V3.5.0

Publish Time: 2022.05.06

Important updates

Marionette animation system

We added the Marionette animation system in v3.4 for complex character animation. It supports state machine editing and weighted blending. In v3.5, we added several crucial new features to the Marionette animation system. Layer and skeleton masks are the most important updates because they allow the developer to separate animation blending for different character parts.

Improvement for 2D-only projects

For 2D users and 2D projects, we have improved the user experience in the editor. It's been a very popular request for 2.x users when they consider upgrading. We have progressively improved things and will continue to do so. In v3.5, you can see the following changes:

All scenes created in 2D projects will only contain a default canvas and a 2D camera (ortho projection).
The scene view is in 2D mode by default.
Some inspector is adjusted for 2D editing.
All 3D modules are not selected by default, and there won’t be 3D features in the additional component panel and node creation panel.
If you want 3D features back, you can just select 3D modules back in the project settings.

Frame Pacing Library (Swappy)

For quite a while, we have been working with Google to bring a better Android development experience to our developers.We are proud to announce Frame Pacing Library has been integrated into v3.5. It's part of the Android Game Development Kit (AGDK). It helps OpenGL and Vulkan games achieve smooth rendering and correct frame pacing on Android. You can activate Frame Pacing in the Android build panel.

Geometry Renderer

A new simple geometry render API is introduced in v3.5. It's designed for simple debug rendering using prebuilt primitive geometry types. It supports lines, boxes, spheres, polygons, etc. You can draw them in wireframe or solid mesh. All drawing geometries are in world space with a configurable transform. Furthermore, some geometries can be affected by real-time lighting.

Detailed functionalities are shown in the following chart.

Material editing improvement

We have put a lot of effort into visual effect upgrades in the past versions. Meanwhile, we have also started to invest in improving the DCC workflow. We are starting to ship some improvements in v3.5.0, and you will see much more coming in future releases. Here are what you can expect in this version:

You will no longer need to dump material and modify it into a new one, you can directly modify the imported material of the FBX/GLTF.
While you edit the material, you can now use undo / redo to reverse or rewind actions.
When switching effects during editing, the same properties (e.g. 'mainTexture') will be cached and retained.

Flatten tool in the terrain editor

Terrain editor now has new brush modes Flatten and SetHeight with a height parameter. It's for more effortless sculpting fixed height planes in the terrain editor.

Platform Abstraction Layer

In v3.5, we assembled all platform-related low-level adaptations into Platform Abstraction Layer, including system info, window adaptation, audio, input, etc. The distribution of system-level events is also unified. This is a low-level refactorization, developer-level API hasn't been affected, but it will allow Cocos to adapt to new environments more easily.

Various performance optimization

We continue to improve performance in v3.5, here are the most visible ones.

The performance of spine and dragonbones on native platforms has been improved by reusing the same buffers between native and JS instead of copying them in previous versions.
Optimized memory occupation of RealCurve, CurveRange.
Optimized decorator performance for particle system instantiation.
Improved WebSocket power consumption on Android by using okhttp for implementation.
Improved Label and Graphics render performance on native with less invocation from native to js.

API documentation redesign

We are genuinely sorry that the previous API documentation usage experience is relatively poor, making the user's learning curve steeper. In v3.5, we are using a new generator to make it more clear and more reliable. It's just a start, and we will continue to improve the content of API documentation in the following months.

Please take a look at our new API documentation page.

Engine repository transfer and customization

To better support open source community, we have merged our engine native repository into engine repository, and it has been transferred to cocos/cocos-engine. Since now, we will be more open by maintaining public issues and public projects. If you are using customized engine, you must pay attention to this change, from v3.5, you only need to clone one engine repository. All customizations in typescript engine can be rebased to v3.5, but previous customizations in native engine must be reapplied manually through diffs. You can refer to the engine customization documentation.

Breaking changes

[FIX] Fix dragonbones/spine sockets transform (engine#10260)

From version 3.5.0，please do not set an using node as the target of sp.Skeleton’s (or dragonBones.ArmatureDisplay) sockets directly, otherwise the transform parameters (Position, Rotation and Scale) will be overritten. The correct way is creating an empty node as the target node, and setting components which to be attached to Skeleton component as children of the target node. For more details and examples please read the Spine Attachment documentation.

Instead of global configuration of shadow bias, now we support individual shadow bias configuration for models, this allows detailed control of shadow effect on simple or complex surfaces. If you have any custom effect, please refer to the upgrade documentation for enabling it.
The effect syntax for Macro Tags and Functional Macros have been upgraded to avoid the occupation of standard glsl define, old effects in project will be upgrade automatically, but if you are using external effects without meta or writing a new one, you have to pay attention.
- New syntax for Macro Tag: `#pragma define-meta`
- New syntax for Funtional Macro: `#pragma define`

Known issues

On iOS 15.4, Apple enabled experimental feature "WebGL via Metal" by default, it's causing some games to have serious rendering issue (graphics not refreshing, strange artifact etc). It's been tracked in the issue, the temporary workaround is to disable `ENABLE_WEBGL_ANTIALIAS` macro in project settings (only disable it for iOS build is suggested). It will probably be fixed in future iOS versions.

V3.4.2

Publish Time: 2022.03.10

In v3.4.1, we improved the data submission and batching strategy of 2D rendering components. Since these are basic changes, it caused some problems with Tiledmap and Graphics. Also, the performance of Spine and Dragonbones on the Android browser has not been improved, these problems have been resolved in the v3.4.2 version.

In addition, under the active testing and feedback from the community, we have also fixed some editor-related experience problems, such as memory leaks caused by script recompilation, and resource copying problems when large projects are built on the iOS platform. Thanks again to the community developers.

Developers currently using v3.4 to v3.4.2 should upgrade to get a better stability and development experience.

Important updates

Version notice

Recently, we have conducted extensive exchanges with the majority of users on forums and offline, and received many pertinent suggestions and criticisms. In response to some product usability issues that have been reported by users recently, we have planned version 3.5 to deal with it as soon as possible, and the public beta will be launched soon. 3.5 will iterate in small steps on the basis of 3.4, improve the usability and ease of use of the product, and ensure stability and compatibility as much as possible.

In the remaining releases for this year, the engine team will also focus on the business needs and pain points of developers, do their best to take care of the needs of various types of projects, and benefit all users. In particular, some projects encountered problems such as heat generation, native performance, package body, editor stability and workflow, which will be mainly solved this year.

V3.4.1

Publish Time: 2022.01.25

In v3.4.1, we focused on fixing problems reported by users after the release of v3.4.0 and improving the overall stability. At the same time, in order to help v2.x developers to upgrade to v3, we adjusted the batch strategy of 2D rendering components, which has greatly improved the overall performance of 2D rendering. Compared with v3.3, the improvement rate ranges from 20% - 70%.

For the performance test results, we also compared the v2.x version. Take a look at the comparison charts below, the performance of most of the tests has been close to or the same as that of 2.x, and a small number of tests have exceeded it.

Legend explanation: All tests are done on low-end and mid-range computers. The four intervals of each icon are Android Web, iOS Web, Android WeChat, and iOS WeChat. In addition, the overall performance improvement on the native platform will also be greatly optimized in the native version of 3.6 [GitHub PR].

In addition, in order to allow WebGL 2.0 to be enabled on WeChat mini-games in the future, we have also modified the build options of the WeChat platform and added an experimental option: support to enable WebGL 2.0 following the configuration of the project module, and to turn off the reduced package by default. If you choose to follow the configuration of the project module, and the WebGL 2.0 rendering backend is checked in the project module, then the future and other WeChat environments that support WebGL 2.0 can be successfully enabled.

Important updates

Refactored 2D batching strategy, RenderData holds static VertexBuffer memory to optimize 2D rendering performance on all platforms
Optimized the state management of 2D rendering components: UV and Color now fill immediately to avoid polluting the VB state
Material.copy now supports modification parameters from override material
Enable WebGL 2.0 on WeChat to prepare for future WeChat versions that support WebGL 2.0
Slightly optimized the performance of the particle system
Fixed the response speed problem when the editor has too many startup scripts
Fixed the problem that an error will be reported when compiling the simulator
Limit the maximum device pixel ratio of the web platform to 2, and fixed the performance degradation caused by it
Fixed event dispatch priority so that UI listeners always take precedence over input event listeners
Fixed the problem of performance degradation in shadow collection logic
Fixed the problem of abnormal exit when restart is called for the second time in iOS/macOS

V3.4.0

Publish Time: 2021.12.20

Cocos Creator v3.4 is the final version we released this year for Creator. Stability is our most important goal! The development and testing cycle of this version is longer than any previous version, and it has been publicly tested in the community for a month. Thank you to all the developers who participated in the test!

In v3.4, not only important functions such as the Marionette animation system have been added, but also a lot of work has been done in terms of product experience, stability, performance optimization, and infrastructure levels. In addition, we listened to the community and fixed a number of problems that have received a lot of feedback. Our devoted engine team believe 3.4 version will become a great milestone in terms of game development user experience!

Highlights

Animation System Marionette

The all new animation system is the most important feature in 3.4. We named it Marionette, which means 'puppet', which both captures the essence of the animation system and also by itself, a long-standing traditional Chinese art form. It has appeared since the Tang Dynasty and has been circulating for thousands of years, and it is still an important opera form till this day in the Minnan region (where our company is located!). With Marionette, we also hope that developers can precisely control the game characters and enhance the game’s narrative ability.

In version 3.4, Marionette supports the key features of an animation system, including state machines, sub-state machines, animation node graphs, trigger variables, multidimensional blending, etc. Of course, more new features are already under development, such as animation levels and masks, humanoid bones and IK support. To help you learn the Marionette animation system, we have also prepared detailed documents, a [Demo](https://github.com/cocos-creator/MarionetteDemo) and video tutorials.

Editor experience optimization

In terms of editor experience, we have done a lot of fixes and enhancement for user experience. Features and experience optimizations include:

The animation editor supports Bezier curve presets now, select the curve segment and click on the curve preset to apply.

Added smart alignment for Rect Gizmo

Customized macros are supported now

Added wrap mode and filter controls for RenderTexture

Added Octree space accleration structure, optimized frustum culling performance that can be activate in the inspector

Lighting Model And Rendering Optimization

Starting from v3.0, Creator has been elevating and polishing its rendering capabilities. In v3.4, in order to improve the rendering quality of the engine, we brought a series of important upgrades. In particular, the enhancement of the lighting model will make the rendering more refined for our engine.

Automatic generation of environment map for diffuse reflection

manually set ambient light vs automatically generate diffuse map

upport HDR and LDR rendering switch (located in the scene node, under Skybox configuration).

HDR on vs HDR off

BL sampling noise reduction( USE REFLECTION DENOISE option under "stardard material")

Denoise on vs Denoise off

Render pipeline enhancement

In terms of rendering pipeline, FrameGraph is an infrastructure introduced in v3.1. After several iterations, in v3.4 we formally docked both the Forward and Deferred pipelines with FrameGraph. Below is a simplified deferred pipeline FrameGraph:

Currently, the engine’s deferred pipeline contains a total of 2 calculation passes and 7 rendering passes. Although it is not complicated, it can already highlight the role of FrameGraph. On the one hand, it simplifies the code organization of the pipeline layer and reduces maintenance costs; on the other hand, it also reduces the cost of developers when customizing pipelines. Based on FrameGraph, the Huawei HMS CG Kit team continued to contribute Clustered Light Culling to the deferred pipeline in v3.4 to optimize the calculation performance of dynamic light sources. It can support hundreds of dynamic light sources on the same screen on the mobile side (Kirin 990 chip in Sponza scene Running 1000 dynamic light sources can reach 40 fps).

In addition, the Subpass in the rendering pipeline is also implemented based on FrameGraph. The second major advantage of FrameGraph is the deferred mode for rendering (different from the deferred rendering pipeline). The engine can analyze the rendering process and optimize it before executing the complete rendering process. Currently, mobile GPUs share system memory with CPUs. One of the hotspots of power consumption is the reading and writing of video memory. Subpass optimization is to make full use of the GPU’s Tiled cache to reduce the power consumption of video memory read and write. When the write and read resources of two adjacent rendering Subpass are the same in-frame resource and will not be referenced by other passes, this Resources can be read and written directly through the Tiled cache without wasting any memory bandwidth, which can significantly reduce power consumption. This automatic derivation of resources and rendering processes is exactly the advantage that FrameGraph brings.

Important Fix and performance optimization

Stability is the primary goal of the v3.4 version, so we have also fixed some flaws that have been troubling for a long time, pushing the stability of the engine to a new height. Here are some of the more important fixes:

Fixed the serious problem that using Active during animation editing may cause data loss.
Fixed the problem that the MissingScript component will appear when some abnormal errors are reported in the scene, which causes the scene to fail to start.
Fixed the crash caused by repeatedly exiting and entering iOS.
Fixed the crash caused by material compilation on some chips in the back end of GLES3.
Fixed the black screen problem of Vulkan backend on some low-end machines (by issuing barriers and image layout conversion more accurately).
Fixed the crash of Vulkan backend on some low-end machines (by modifying some shader usages to workaround some problematic drivers).
Fixed the problem of Vulkan backend crashing or incorrect resolution when rotating or splitting screens.
Fixed a crash when using a large number of high-resolution textures in the Vulkan backend.
Fixed the black screen issue on Chrome on a few devices.
Fixed the problem that PrefabInstance in mountedChlidren may cause data errors.
Fixed the fileId conflict that may occur when copying Prefab, which will cause data loss and error.
Fixed the problem that the deleted element data is referenced in Prefab, which causes a lot of redundant data to be serialized.
Fixed the issue that Undo may cause some override data in the prefab to be lost.
Fixed the problem that data errors may occur when the terrain is restored.
Fixed the problem that the GPU memory referenced by Label is not released after switching scenes at runtime.
Fixed the memory leak problem of InstanceBuffer and BatchedBuffer due to holding aglobal Map.
Fixed a large number of problems caused by the failure of global precision designation on some small game platforms, such as the shadow sampling problem.
Fixed the problem that the native platform did not pass the correct baked parameter in the case of scene baking.
Fixed the random model flickering issue under GLES (by using glMapBufferRange instead of glBufferSubData).
Fixed the screen glitching issue on devices that do not support floating-point mapping when there are NaNs in the model's joint weights (by equally dividing all NaN weights in the importer).
Fixed the crash of large-scale data synchronization after the native-side pre-baked animation Instancing is processed.
Fixed the problem that multiple plugins with the same name and registered resources will cause script compilation to fail.
Fixed the problem that the content of the remote resource package cannot be updated after the native platform is rebuilt feedback from the forum.
Fixed the problem that the original code is still entered into the apk after the original selection encryption is built feedback from the forum.
After repairing the automatic atlas using compressed textures, modify the atlas configuration to rebuild and still use the cache.

In addition to fixing important issues, the overall performance of the engine has also been improved, such as 2D rendering and batch efficiency, physical performance, iOS Web 3D scene performance, and Android partial scenes. Here are some test results of 2D rendering:

Known Defects and Potential Compatibility Issues

Build Template Upgrade

Due to the adjustment of the relevant logic of web platform screen adaptation, we have changed the web-related index.html template, which includes preview templates and building web platform templates. We have done related compatibility processing inside the engine cocos-creator/engine#9830

This process will ensure that there is a fixed div structure inside index.html:

<div id="GameDiv">
    <div id="Cocos3dGameContainer">
        <canvas id="GameCanvas"></canvas>
    </div>
</div>

If GameDiv/Cocos3dGameContainer is missing, it will be automatically filled during runtime.

IBL sampling noise reduction

The newly added IBL sampling noise reduction algorithm currently has some problems with the compatibility of the iOS Web environment. Since it was found that it was not merged in the version later, the support for iOS Web will be completed in the follow-up 3.4.1

Delayed pipeline defects

Currently, the deferred pipeline is still in the process of high-speed iteration, and there are still some problems with function and platform compatibility. It is not recommended to use it in actual projects for the time being. Some of the current known issues include some particle blending modes that cannot be rendered, builtin-toon materials are not supported temporarily, some low-end platforms and devices have compatibility issues, spotlight shadows are not supported, and 2D & 3D camera mixing issues.

V2.4.7

Publish Time: 2021.11.24

To do their job well, a worker must first sharpen their tools. After a long period of preparation and testing, version 2.4.7 is finally released. Thank you to all the friends who gave us valuable feedback! In this update, we have concentrated on fixing some 2.x-related issues that we have discovered recently, focusing on improving the stability of the editor, and we recommend that all 2.x users upgrade.

According to the plan when the 3.0 version was officially released on February 7 of this year, 2.4 as the LTS version will continue to provide bug fixes this year. At the same time next year, we will continue to pay attention to 2.4 key issues and major platform adaptation issues, and update the version from time to time to support the safe operation of online projects.

Once again, to answer questions about the 3.x upgrade:

New projects are no longer recommended based on 2.4, please use the 3.x version for development, we will continue to optimize the 3.x development experience, pay attention to the package and efficiency of lightweight games, and support 2D, 3D and other different types of game development.
If the current 2.x project has reached the mid-development stage or is about to go online, there is no need to upgrade to 3.x.
If the current 2.x project is still in the early stages of development, you can evaluate whether you need to upgrade to 3.x. If you are sure to upgrade, you can use the 2.x resource import tool provided by Creator. This tool will support the perfect import of old project resources and the auxiliary import of codes. Code-assisted import will convert js into ts, add component type declarations, attribute declarations and function declarations. The references of components in the scene will be preserved, and the code inside the function will be imported in the form of comments, which can reduce the developer’s upgrade Difficulty. For detailed upgrade instructions, please refer to Upgrade Guide. If developers encounter difficulties during the upgrade, please feel free to give us feedback and we will try our best to assist.

Upgrade Tips

As Cocos Creator 3.0 version has been officially released, v2.4.x will be used as the LTS (long-term support) version, providing continuous updates for the next two years! In 2021, 2.4 will continue to be updated to provide bug fixes and new mini-game platform support to ensure the successful launch of your project; in 2022, we will continue to provide developers with the key to 2.4 Bug fixes to ensure the smooth operation of online games! therefore:

Existing 2.x projects can continue to develop without compulsory upgrade to 3.0.
For new projects, it is recommended to use version 3.0 for development. We will continue to optimize the development experience and operating efficiency of 3.0 to support the smooth launch of heavy games of different categories such as 2D and 3D.

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Most projects can usually be upgraded automatically, but because the project is inevitably unique, developers should try and evaluate the new version of the engine in advance according to the needs of the project. In addition, due to stability considerations, it is recommended that projects that are about to go online or already online should be carefully upgraded. The following is the upgrade instructions. If developers encounter difficulties during the upgrade, please give us feedback and we will try our best to assist.

Upgrade from <2.4.0 version

cc.loader is no longer recommended, please use the latest cc.assetManager instead, please refer to the Resource Management Module Upgrade Guide
The sub-package function has been upgraded to Asset Bundle, please refer to the Resource Subcontract Upgrade Guide
Adjusted the directory structure after the project is built and adjusted the API of BuildResults. If you use the editor plug-in to get the editor’s build results, please refer to Customized Project Build Process Upgrade Guide
The cc.RawAsset that was deprecated since 1.10 has been officially removed, please use cc.Asset instead. Since 2.4 is no longer compatible with the legacy usage of the RawAsset type in the original 1.x project, it is recommended that all projects to be upgraded to 2.4, especially those upgraded from version 1.9, be edited in any 1.10 ~ 2.3 version. All warnings or errors output when the compiler compiles the code are processed correctly, and then upgraded to 2.4.
cc.Color.fromHex is deprecated, please use cc.Color.fromHEX interface

Upgrade from < 2.3.3 version

The CCTexture2D and CCTexture2DRGB methods in the Effect have been abandoned.
Vec3.FRONT has been abandoned, please use Vec3.FORWARD instead.

Upgrade from < v2.3.0 version

Since v2.3.0, Android and Android Instant use the same build template, please note:

If the code is used solely by the Android platform, please put it in the app/src directory, and the third-party library used by itself, please put it in the app/libs directory.
If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.
For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.
proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.
When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute in stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.


// Assuming testNode is a node in the scene, if it was manually

// removed from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

If a node is managed via cc.NodePool, it is not affected.

V3.3.2

Publish Time: 2021.10.11

Highlights

The main function of this version is to allow native applications built by the engine to support iOS 10+. In order to support iOS 10+, the engine code removed the dependency on C++17.

Some functions of the engine depend on C++17, and some functions require using the Android API. For the convenience of developers, the function configuration interface of the editor prompts for these dependencies. For example, when Android uses the delayed pipeline, Android API 21+ is required. If the configuration chooses to use the delayed pipeline, the editor will prompt the required Android API version:

Of course, we also provide a complete document explaining the requirements of each functional module for the Android API and C++ versions. For more information, please refer to the native options documentation.

What’s new!

Performance optimizations

In version 3.3, the focus continues to be optimizing the loading performance and running performance of the WeChat mini-game platform. After all internal projects are upgraded, the WeChat cloud testing starts with a performance score that can reach more than 80 points.

We continue to leverage the native binding layer to a new level, we have implemented a native version of render scene, lighting, model and other render objects, the render objects collection process is also completely running with native implementation, which further improved the performance of the native platform.

There is also a side benefit. Due to the upward migration of the binding level, some underlying data sharing mechanisms have been lifted, such as Pass, SubModel, etc. This makes the implementation of the upper layer of the JS engine, especially the data related to the UI and 2D rendering batches more simplified, and the data structure of some high-frequency operations is restored from TypedArray to direct properties, which makes the performance of the Web and small game platforms also visible improvements .

Optimized Scene editing experience

Optimize the roaming mode of the scene camera, and add an acceleration switch.

2. Add a scene light switch (open by default).

3. Increase the display of the maximum and minimum coordinates of the model.

4. Increase the snap function of Transform Gizmo (when you move, rotate, zoom Gizmo, hold down the Ctrl key, you can increase the value according to the set step length.

5. Optimize the experience of using large projects: reduce the memory usage of the editor, avoid crashes, and optimize lag.

New Animation Editor and Animation Data upgrade

Currently, the Animation Editor has built-in curve editing, which matches the time axis, and supports the editing of the time curve between any key frames.

Animation Data has also bee upgraded to introduce a new basic curve class, refactoring AnimationClip, and unifying the curve data used by animation and particle systems. These works are prepared for the subsequent improvement of the animation system. In the subsequent version, we will support advanced functions such as animation state machine editing and Blend Tree animation fusion.

In addition, the Animation Editor also:

Supports the animation display editing after the animation root node is hidden.
Optimizes the occlusion relationship between the key frame of the Animation Editor and the small red line, the size of the key frame, the selected color, etc…
The Animation Editor supports holding down shift + mouse wheel scrolling to move the timeline.

Platform support and Build system optimizations

Windows x64 build option have been added, and the win32 platform will be gradually deprecated in the future.

In the Build panel, there are many new optimizations:

The iOS build configuration option supports developer id configuration related to the target iOS version and signature.
After constructing md5Cache, you can add md5 suffix to the script to ensure that the version is updated; (feedback from the forum.)
As some versions of WeChat already support astc, the compressed texture configuration of the small game platform astc is currently open.
Preferences-Build a new option to open the build log.
Build an interstitial configuration panel, which supports direct drag and drop of pictures in the file system to place.
Command-line construction supports the input logDest to specify the log output path.
Due to the limitation of the number of exit codes on the Mac, the command line to build the exit code has been modified.
After the native platform is built, the game name cannot be modified a second time.

Shadow effects and settings optimization

In previous versions, the configuration of shadows has always been a feature that confuses developers. We have a complete plan and are gradually improving shadow support. v3.3 will first simplify the configuration of shadows, optimize soft shadow algorithms, and repair shadows. Part of the effect problem. Configuration adjustments include:

Shadow color is migrated to the grayscale adjustment option of Shadow saturation, which will automatically migrate the alpha channel of the old version.
The soft shadow options are changed from the previous X9, X25, etc. to Soft and Soft2X.
The size of the simplified shadow map is set to High, Medium, Low.
Remove the SelfShadow option, now self-shadow calculation will be turned on by default.

v3.1

v3.3

Perfect Physics system

As v3.1 supports the PhysX physics backend, the selection and use of multiple sets of physics engines has also become our focus of use experience. In v3.3, we not only strengthened the physical functions, but also unified the different physical backends as much as possible.

Support CCD continuous collision detection function

Increase the minimum volume control of the collision body to avoid a series of problems caused by node zero scaling.
Supports more flexible configuration options for the PhysX physical packed byte platform.
Support the global control in Bullet physics to allow automatic sleep.
Support Bullet physics in ray detection filter trigger collision body.
Fix local inertia with no additional status of rigid body in Bullet physics.

Other

After the audio system removed the playback control interface on all AudioClip resources in v3.1, the developers were quite dissatisfied. In v3.3, we added the playback control interface back to the AudioClip resource by marking it as obsolete. We still hope that all developers can switch to using the AudioSource component to play audio, which is essential for future audio system enhancements.
Input events were dispatched before they were received. If the event response logic is complex, it may affect the frame callback and cause the frame rate to be unstable. v3.3 has been adjusted to the inter-frame recording event queue, and the events are processed in the main loop. Queue.
The View and Screen interfaces have been simplified, some platform-related interfaces have been discarded, and some of the View’s window control functions have been unified on the Screen.

If the code is used solely by the Android platform, please put it in the app/src directory, and the third-party library used by itself, please put it in the app/libs directory.
If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.
For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.
proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.
When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute in stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.

// Assuming testNode is a node in the scene, if it was manually

// removed from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

If a node is managed via cc.NodePool, it is not affected.

Upgrade from < v2.0

V3.1.2

Publish Time: 2021.07.15

What’s new!

Cocos Creator 3.1.2 mainly fixes the stability problems of v3.1 and optimizes the editor workflow. All developers are welcome to use and experience! Please make a backup of relevant files before upgrading! The following is the detailed update content.

v3.1.2 is a version that optimizes experience and performance on v3.1.1. The update content of this version is not included in v3.2. Later, the v3.1.2 update will be merged into v3.2.1 and v3.3.0!

Since 3.1.0, the engine group has actually been advancing three version lines in parallel, v3.2.0, v3.1.x, v3.3.0, of which v3.2 has a requirement for the release of Hongmeng 2.0, so the release date is set early Now, for stability, the main reason is to increase the Hongmeng platform support on the basis of v3.1.1. After that, we continue to receive feedback from developers about 3.1. In order to more effectively solve the pain points encountered by developers and lower the upgrade threshold for developers, we have decided to continue to optimize the experience and performance on v3.1.2 Performance, delivered to developers. At present, Cocos Creator v3.x, as a new 3D engine, is still far from the expectations of developers. We hope to give developers stronger confidence through this practical action of continuous delivery.

V3.1.0

Publish Time: 2021.05.12

The launch of Cocos Creator v3.0 marks a new journey for Creator, and Cocos Creator 3.1 is the first cornerstone of the journey. This version update brings many great new features, including deferred rendering contributed by the Huawei HiSilicon team. Pipeline, PhysX physics backend support, etc.; at the same time, compared to version 3.0, various aspects of performance have also been optimized, such as frame animation performance, loading performance, package body, and so on. We will continue to cultivate deeply on the basis of 3.x, with a sincere attitude and dedicated spirit, steadfastly improve the product experience, and benefit all developers. All developers are welcome to use and experience! Please make a backup of relevant files before upgrading! The following is the detailed update!

What’s new

Added deferred rendering pipeline (thanks to the contribution of the Huawei HiSilicon team), you can select the deferred rendering pipeline in the project settings：

Introduce multi-threaded rendering architecture. On the native platform, the traditional single-threaded architecture can no longer meet the rendering of large-scale scenes. Therefore, Creator initially split the traditional single-threaded architecture into two main threads, a rendering thread and a device thread, in v3.1. In addition to the split of the main thread, Creator also parallelizes the submission process of command buffers to speed up rendering efficiency. The multi-threaded rendering architecture diagram is as follows:

Added PhysX physics support, currently supports native platforms other than Android x86, and has a performance improvement of more than 100% on iOS (if you need to preview on the web platform, you can refer to the physics-3d project in example-3d, the main content is modified In the preview-template folder):

The editor supports bone octahedron display, you can visually see the distribution status of the model bones:

Support previewing animation on the Inspector of FBX/glTF resources:

Open the new version of the curve editor, support to edit the left and right slopes separately, and support the cycle mode of directly displaying the curve:

Android platform supports the construction of x86_64 architecture.
Support adding/removing components on the Prefab instance.
The Mac build supports the M1 option, which is used to better prompt the support issues of some known engine modules on Apple M1 (Silicon) architecture devices.
Added the laboratory function of scene instant cache, which is enabled by default, and can restore data after the scene exits abnormally.
The editor adds ui-curve and ui-curve-editor components, which can be used directly by plug-in developers.

Release Notes

Improvements

Improve the operating performance of the engine’s native platform.
Improve the performance of engine frame animation.
Improve the loading speed of runtime resources (build mode).
Optimize the stuttering problem of the animation editor when editing a large number of key frames.
The auto atlas panel adds three optimization options when using auto atlas in the Bundle, which is used to eliminate unused resources in the auto atlas in the Bundle to reduce the package body.
Optimize the problem that the automatic atlas is referenced by multiple Bundles, which causes the pictures to be copied, and reduce the package body.
Shadow Map supports linear depth, depth map compression (mutually exclusive with linear depth function), self-shadow effect, and normal bias parameter settings.
Lighting Map supports RGBE format.

Editor

Optimize the event editing panel of the animation editor to avoid generating empty function data.
The release path of the build release panel is adjusted to a switchable protocol header.
The export/import build configuration function of the build release panel supports cross-version import after export.
The build release panel adds a verification mechanism, and the build cannot be built when the build options are filled in incorrectly.
Optimize the output log of packaged rpk for some small game platforms.
Optimize the construction of output log information and fix the problem of log loss.
Optimize the handling of resource loss, which can be automatically restored after resource recovery.
New Button locks the Label node by default, making it easy to select in the scene.
Fix the scene data problem that may be caused by exiting from Prefab.
The animation baking rate can be selected when FBX is imported.
Solve the problem that some FBX import will cause the editor to freeze.
FBX/glTF adds import option Promote single root node.
Fixed the issue that TiledMap was lost when importing .tmx resources.

Engine

Fixed the problem of TiledMap animation failure.

Fixed the issue that the transparency display of Spine was abnormal when the premultiplication was turned on.
Fixed the incompatibility of Vulkan drivers for some models.
Fix the problem that the Shadow Map display of Metal related platforms is disordered.

Breaking Changes

The playback interface of AudioClip has been removed, and the started event monitoring is not supported. AudioClip is now a pure audio resource type.
You can no longer directly call the CCStandardShading function in the effect resource, and encapsulate it in the CC_STANDARD_SURFACE_ENTRY macro definition. It is recommended to only do custom logic in the surface function.
Rename the GFX module, remove the GFX prefix, and use import {gfx} from'cc'.
The automatic atlas and compressed texture switches have been removed from the build panel, and the project will be processed directly after the automatic atlas and compressed texture are configured.
Deprecated cc-fog header files, use cc-fog-vs and cc-fog-fs instead.
Removed some constants under sys, including sys.LINUX, sys.BLACKBERRY, sys.EMSCRIPTEN, sys.TIZEN, sys.WINRT, sys.WP8, sys.QQ_PLAY, sys.FB_PLAYABLE_ADS.

Known Issue

There is a problem with the keyboard and mouse adaptation of WeChat PC. We will fix this problem in v3.1.1. You can merge this PR manually to fix #8626.
The SafeArea component is temporarily unavailable. We will fix this problem in v3.1.1. You can solve this problem by manually merging this PR #8652.

If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.
For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.
proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.
When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute in stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.


// Assuming testNode is a node in the scene, if it was manually

// removed from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

If a node is managed via cc.NodePool, it is not affected.

Upgrade from < v2.0

V3.0.0

Publish Time: 2021.02.07

After the v3.0 preview was released, the engine team received a lot of enthusiastic feedback from developers, this feedback really helped to increase the team’s motivation to release an amazing product. Creator v3.0 unifies the development workflow of 2D and 3D, taking into account the development experience from light and heavy games, and integrates almost all the functions of Creator v2.x and Creator 3D 1.x. v3.0 now encompasses these versions under a single umbrella.
v3.0 has been further optimized in performance, improved quality, and introduces more features, such as access to the native runtime of Spine and DragonBones, support for the use of NPM libraries, and refactored the Prefab system and UI System and many other contents.

What’s new

v3.0 uses a new future-oriented engine architecture, which will bring high-performance, data-oriented and load-balanced renderers to the engine, and seamlessly support Vulkan, Metal & OpenGL ES multi-backend rendering. In the future, we also plan to support mobile VR/AR and some of the desktop & console platforms. Below is a brief introduction to core features of v3.0.

Powerful editor features

The integrated editor brings a lightweight and easy-to-use creative experience. Cocos Creator v3.0 is refactored, expanded and upgraded on the editor framework that Cocos Creator 2.x has used for many years.

Brand new interface design, more concise and clear.
Resource system upgrade, enhanced support for super large projects, more efficient and reliable.
Code isolation between modules, pure message-driven, more stable.
The extension system is completely modularized to welcome a more powerful plug-in mechanism.

One-click access to Cocos’s quality services

Cocos Creator v3.0 provides one-click access to various high-quality services officially launched by Cocos, improving development efficiency and launching more high-quality content. Cocos will continue to launch additional and improved services.

Brand new Prefab system

Creator v3.0 re-implements the Prefab system with features such as:

Support Prefab automatic synchronization.
Prefab instance can overwrite attributes in Prefab resource.
Support Prefab nesting.

Build system

Build content caching

After building, Creator v3.0 will cache most of the build content, including resources, compressed textures, automatic atlas, engine code, etc. In the subsequent build, if nothing has changed, the cached content will be used directly to speed up the build and improve efficiency.

Task-based build list

The build and publish will be carried out in the form of build tasks, saving the configuration, status, log, etc. of each build, making it easy to switch build tasks and view historical configurations.

Compile and generate separately after build

The generation stage of each mini game platform is extracted, allowing to modify the content of the file after build to regenerate rpk/cpk.

Build process hooks

The build extension support adding hooks before and after compilation to customize the build process.

Support Asset Bundle

Creator v3.0 uses Asset Bundles as a resource modularization tool. Developers can build textures, scripts, scenes and other resources into multiple Asset Bundles, and then load them on demand during the game’s running process, thereby reducing the time required to download and load the game for the first time. Asset Bundles can be placed freely as required, for example, they can be placed in remote servers, local, or sub-packages of small game platforms, or they can be reused across projects to load Asset Bundles in sub-projects.

Splash Screen

It supports setting up Splash Screen during construction, which is used to display a cutscene before the game starts, and optimize the startup speed of the first screen.

GameView

GameView is a game running panel embedded in the editor. Developers can run the game directly in the editor without opening the browser preview. In addition to a more seamless development experience, debugging and modifying element states in real time through the scene editor or other panels during the game running process, making game development more efficient!

Extension

Powerful extension system

Cocos Creator v3.0 has a more powerful extension system. Almost all internal modules of the editor are built with extension system. You can quickly create your own extensions in the extended menu to achieve the customizations you want. In addition, Creator v3.0 also provides an extension manager, which can easily manage the operation and uninstallation of all extensions.

Message communication

Extensions can use IPC messages to communicate with other extensions or the editor core, and quickly and easily use the capabilities provided in the editor. Cocos Creator v3.0 also provides a message manager, which can clearly see the functions currently provided in the editor, reducing the threshold for extension development.

Animation Editor

The Animation Editor is an important module that we have been continuously optimizing. In addition to standard displacement, rotation, zoom animation and sequence frame animation, this animation system also supports driving arbitrary component attributes and user-defined attributes, plus it can be edited at will The time curve and innovative movement trajectory editing functions allow content producers to produce various dynamic effects without writing a line of code, and drive the game logic at will.

In addition to regular operations, the v3.0 Animation Editor also provides the following shortcut operations to help game developers achieve the desired content:

Batch key frame interval adjustment.
Copy and paste across node tracks.
Indirect attributes (such as material attributes) keyframe editing.
Directly select resources and directly edit key frame data in the animation editor.
Multi-select key frame zoom, move and delete.
Support multi-select nodes to add attribute tracks in batches.
Support copy and paste all animation data on the node.
Support shielding no key frame nodes and search nodes.
Support editing component tracks.
Support to adjust the layout of the animation editor.

A more complete tool chain

Support model preview.
- After selecting the model in the editor, you can preview the model resources in all directions, and you can also view various textures used in the default materials.
New version of FBX importer.
Support the import of glTF resources, support khr-draco-mesh-compression, sparse accessor.
Support animation cutting.
Provide Mesh Optimizer tool.
Model import support quantized joints/weights.

Terrain Editor

Convenient terrain system to quickly draw terrain textures. Terrain editing mainly includes three major functions: Manage, Sculpt, and Paint. It also supports Normal Map, PBR material and custom material.

Built-in baking system

Baking is the process of generating light maps by pre-calculating the influence of light sources on objects and shadows projected with very high level of details. The light maps are then applied to the scene in runtime very efficiently, which can greatly improve the graphics quality of static scenes.

Configuration

Visual macro configuration

Provides a shortcut to modify the engine macro configuration. The configured macro will take effect during preview and build. At the same time, the default value of the current macro configuration will be updated with the configuration of the custom engine.

Batch configuration of compressed textures via presets

Support for adding compressed texture preset configuration, which is used to quickly configure the compression method of texture. After setting presets for image assets, you can also directly modify the presets to update the configuration for corresponding textures all at once, which greatly facilitates the overall management of the project.

Support 2.x project migration

In order to facilitate the upgrade of 2.x users, we provide a project migration plugin in 3.0, which can migrate projects above version 2.4.3 to version 3.0.0. This tool will support the perfect import of old project resources and the auxiliary import of code. Code-assisted import will convert js into ts, add component type declarations, attribute declarations and function declarations. The references of components in the scene will be preserved, and the code inside the function will be imported in the form of comments, which can reduce the developer’s upgrade Difficulty. However, there is still a big difference between the 2.x API and 3.0. We use deprecation and removal mechanisms to make runtime warnings as much as possible. But developers still need to make a lot of adjustments to the code in order to upgrade to 3.0 perfectly.

Powerful engine features

Cocos Creator v2.4 is very powerful in 2D rendering, while Cocos Creator v3.0 allows developers to make more beautiful 3D games. We have integrated the advantages of the two in 3.0, and fully support various functions of 2D and 3D. Whether 2D or 3D, 3.0 will meet your needs.

Rendering system

As the core module of the game engine, the rendering system plays a vital role and directly determines the content that the game can output to the player. An excellent rendering system must also take into account various platforms and smooth the differences between platforms. The rendering system of Cocos Creator v3.0 aims at future-oriented, high-performance, and cross-platform from architecture to design, which greatly improves rendering capabilities and robustness.

Supports multiple rendering backends of Metal, Vulkan, WebGL 1.0, WebGL 2.0, GLES2, GLES3, and provides a unified GFX graphics API layer to the rendering pipeline layer.
The GFX API design close to the modern graphics API helps the rendering pipeline layer to release the performance and possibilities provided by the modern graphics API as much as possible.
Built-in forward rendering pipeline, support user-defined rendering pipeline.
Physically based light sources, cameras and materials help developers use industrialized processes to create the most realistic visual effects.

Supports GPU Instancing batch optimization, which is suitable for drawing a large number of dynamic models with the same mesh, and supports instancing batches of models containing skeletal animation calculations.

Support global fog effect.

Powerful native renderer, using memory sharing mechanism to reduce JSB calls and speed up data access.
Support ASTC, ETC, ETC2, PVR and other compressed textures.

Light and Shadow

In the 3D world, light and shadow have always been extremely important components. They can enrich the environmental performance, and good quality shadows can achieve a fake effect and make the whole world more three-dimensional.

Physically based light source.
Cocos Creator v3.0 uses optical measurement units to describe light source parameters. Based on optical measurement units, we can convert all the relevant parameters of the light source into physical values in the real world. In this way, the designer can adjust the light intensity, color, range and other information according to the actual lighting industrial parameters and the actual physical parameters of the real environment, so that the overall lighting effect and light attenuation are more in line with the real natural environment.

Multi-light support based on multi-pass.
Support high-performance flat shadow Planar Shadow.
Directional light and spotlight dynamic shadow based on Shadow Map, support PCF soft shadow and GPU Instancing.

Particle System

The particle system is the basis of the special effects of game engines. It can be used to simulate natural phenomena such as fire, smoke, water, clouds, snow, and fallen leaves, and it can also be used to simulate abstract visual effects such as luminous trajectories and speed lines. Good particle effects can make the game screen more stunning.

Support up to dozens of module settings, and support various types of curves, constant changes.

Support GPU particles, greatly improving rendering performance.
Support Cocos traditional 2D particles.

Material System

As a resource, material determines the rendering effect of the attached object. Almost all the rendered effects in the game are inseparable from the material. As a basic module, the material system provides a solid foundation for the superstructure.

Built-in physical-based standard materials.
Support Cocos Effect.
The Cocos Effect based on YAML and GLSL designed by Cocos is a single-source embedded domain specific language(single-source embedded DSL). The YAML part declares the flow control list, and the GLSL part declares the actual Shader fragment. The above complement each other and together constitute a complete rendering process description.
Support more than 32 Effect macro definitions.
Cocos Effect compiler automatically removes invalid codes.
Support importing Effect header files.
Effect’s resource panel now supports previewing the compiled Shader code, and supports visual editing of each Define of the Shader.
Support material preview.

Middleware

Support TiledMap.

Support Spine, DragonBones.
Support Spine, DragonBones and TiledMap rendering in 3D scene (need to customize material to control depth detection).

Skeleton Animation System

Cocos Creator v3.0 has a built-in general animation system to display animation based on key frames. In the editor, we can easily produce key frame animation clips. We can also support importing skeletal animations already contained in external FBX and glTF resources. These animations can be edited in the resource manager. Animation effects can be previewed in the animation editor, animation event triggers can be added, and animation system APIs can be used. You can also freely control the animation playback.

In addition, we also support the following features:

CPU or GPU driven skeletal animation, can be switched freely.
Supports the fusion transition of animation (CPU driven).
Use binary format to store skeletal animation to reduce file size.
Support two components: general animation and skeletal animation.
Support material sub-attribute animation such as Uniform.
Support CPU driven Morph Target (Blend Shape).

Script system

The project development of Cocos Creator v3.0 has fully turned to TypeScript, and JavaScript is no longer supported in the project except for plug-in scripts in JavaScript or NPM modules. TypeScript support has been improved in v3.0:

Embrace ES6 and TypeScript, complete code hints and automatic import.
Attributes support independent type decorator: @integer, @float, @string, @boolean, @type etc…
Support Async Await syntax.
Optional Chaining support.
Nullish Coalescing support.
Certain circular reference behaviors will be detected and warned during operation.
Added core-js polyfills to help some low-end platforms complete ES6 support.
Support loose compilation mode, which can reduce package body and optimize performance.
Support using NPM modules.
Subdivide engine modules, allowing more detailed module removal.

UI system

Cocos Creator v3.0 continues the 2.x UI design, and further optimizes and upgrades, including the following:

Flexible and concise 2D rendering and UI interaction, layout components, support 20 kinds of components including Sprite, Label, Button, Widget, etc. You can use these basic components to combine various types of UI effects.
Support static batching.
The engine provides the UIStaticBatch component. UIs that do not require frequent changes can use this component to cache rendering data, thereby reducing rendering consumption and improving performance.
Support dynamic image combining at runtime, reduce the number of drawcalls, and optimize performance.

Merged the UI rendering process and the forward rendering process, allowing 2D and 3D rendering components to be mixed, and rendering visibility is completely determined by the node Layer and camera Visibility.

Physics

Cocos Creator v3.0 currently has a built-in lightweight collision detection system Builtin and a physics engine cannon.js with physical simulation, as well as a powerful bullet compiled into asm.js/WASM version ammo.js, and provides users with an efficient componentized workflow and convenient usage.

Support multiple physical backend options, including ammo.js, cannon.js and more lightweight builtin physical.
Support WeChat mini games using WASM physical backend, which can achieve higher performance on iOS.
Physics system supports fixed step refresh.
Support physical materials.
Supports a variety of practical collision bodies including simple shapes, cones, planes, terrain, capsules, cylinders, static mesh collision bodies, etc…

Support point-to-point and hinge constraint components.
Mesh collider adds convex hull approximation function.

Support traditional Creator 2D physics and collision system.

In a near future, we will provide builtin PhysX backend on native platforms, which will greatly improve performance and physics capabilities.

When the terrain’s size is not by n*n, the baking process will fail.
Upgraded old project from v2.x might have property referencing issue in prefab data, please refer to this topic 1 for detailed information and fix.

Breaking changes

The built-in effects of the engine source code are uniformly changed to a different naming rule from the editor resources. If an effect is not used at all in the project scene, it will not be obtained by using the effect name in the script (such as builtin-unlit, etc.). It is recommended that when developers need to create materials programmatically, they should uniformly expose the effect asset as the property of the script, mount it in the scene, and then directly pass in material.initialize.
The editor HOME directory has been switched from \~/.CocosEditor3D back to \~/.CocosCreator, and the plugin directory has been renamed from packages to extensions. Plugins after 3.0 will be stored in \~/.CocosCreator/extensions and PROJECT/extensions.
The original subdomain plan is no longer applicable, please switch to the latest subdomain plan.
No longer supporting JavaScript, only TypeScript.
cc.global variables are no longer supported, please use module import.
The 2D node will now strictly judge whether it can be rendered according to the visibility of the layer and the camera. If multiple cameras exist, there may be repeated rendering, and the layer of the node needs to be re-adjusted.
Refactored physics events. Events between static rigid bodies are no longer supported. It is recommended to add a Kinematic or Dynamic rigid body component to the corresponding node of the collision body that monitors the event.
Unable to upgrade to the Prefab of the new Prefab system, it will break the relationship and restore to a normal node.

Existing 2.x projects can continue to develop without compulsory upgrade to 3.0.
For new projects, it is recommended to use version 3.0 for development. We will continue to optimize the development experience and operating efficiency of 3.0 to support the smooth launch of heavy games of different categories such as 2D and 3D.

The original Cocos Creator 3D, as a branch version of Creator, has been iterated in China for a year, and has successfully launched major projects such as Starry Sky Battle and The Strongest Magic Fighter! After 3.0 is released, Creator 3D will also be included in 3.0, and existing 1.2 projects can be directly upgraded. Therefore, Cocos Creator 3D will not release a separate version in the future, and we hope developers using Creator 3D versions to be noticed.

Although we do not recommend projects under development, especially those that are about to go online, to upgrade to 3.0, we will still launch 2.x resource import tool in the 3.0 official version. If the existing project needs to be upgraded for special reasons, and you encounter technical or workload difficulties, you can also contact zhengxiong.zhao@cocos.com for our manual assistance!

Upgrade Tips

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Projects under development can usually be upgraded seamlessly, but because of the uniqueness of each project, developers should conduct a technical evaluation based on their project’s own needs. If developers encounter difficulties in upgrading, please feel free to give us feedback and we will try our best to assist. In addition, due to stability considerations, it is recommended that projects that are about to be launched or already launched be upgraded with caution.

Upgrade from <2.4.0 version

cc.loader is no longer recommended, please use the latest cc.assetManager instead, please refer to the Resource Management Module Upgrade Guide
The sub-package function has been upgraded to Asset Bundle, please refer to the Resource Subcontract Upgrade Guide
Adjusted the directory structure after the project is built and adjusted the API of BuildResults. If you use the editor plug-in to get the editor’s build results, please refer to Customized Project Build Process Upgrade Guide
The cc.RawAsset that was deprecated since 1.10 has been officially removed, please use cc.Asset instead. Since 2.4 is no longer compatible with the legacy usage of the RawAsset type in the original 1.x project, it is recommended that all projects to be upgraded to 2.4, especially those upgraded from version 1.9, be edited in any 1.10 ~ 2.3 version. All warnings or errors output when the compiler compiles the code are processed correctly, and then upgraded to 2.4.
cc.Color.fromHex is deprecated, please use cc.Color.fromHEX interface

Upgrade from < 2.3.3 version

The CCTexture2D and CCTexture2DRGB methods in the Effect have been abandoned.
Vec3.FRONT has been abandoned, please use Vec3.FORWARD instead.

Upgrade from < v2.3.0 version

Since v2.3.0, Android and Android Instant use the same build template, please note:

If the code is used solely by the Android platform, please put it in the app/src directory, and the third-party library used by itself, please put it in the app/libs directory.
If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.
For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.
proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.
When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute in stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.


// Assuming testNode is a node in the scene, if it was manually

// removed from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

If a node is managed via cc.NodePool, it is not affected.

V2.4.2

Publish Time: 2020.07.30

Following the release of v2.4.1 last week, Cocos Creator has brought you the long-awaited byte game platform support! A new platform always means new opportunities and challenges, and will bring more users and potential to developers. We also look forward to the explosion of more excellent products on byte games! We recommend that developers who need to release byte games upgrade the engine to the latest version to get the best experience.

What’s new

Byte games

The byte game is developed based on the full product matrix of Bytedance and includes such creations as Today Toutiao, TikTok and Today Toutiao Speedy Edition. It does not require users to download, just click to open the new game type that is ready to play. ByteDance’s full product matrix takes content distribution as the core, and promotes the distribution of small games through content, and uses content to bring volume and fission to small games. Currently, there are very rich application scenarios. There are traffic portals in natural search, feed stream, personal homepage, small video, video comment area, etc. For detailed instructions, please refer to the Understanding Mini Games: Overview of Traffic Portals article (Chinese Only). In terms of revenue, ByteDance currently supports both advertising and in-app purchases.

For games developed with Cocos Creator, developers only need to select the ByteDance game publishing platform when building, and Cocos Creator automatically completes the adaptation and building. For details, please refer to the Publish to Byte Games documentation.

Known issues

After the iOS device is upgraded to iOS 14 beta.3, there will be a problem that the web platform cannot display the screen temporarily. You can customize the engine and manually merge the changes #6974 for repair.

v2.4.1 Byte platform has been unlocked synchronously

Cocos Creator v2.4.2 and v2.4.1 are exactly the same in terms of product functions, so the release portal of byte games for existing v2.4.1 users has been unlocked through hot updates. v2.4.1 users only need to start Cocos Dashboard v1.0.8 when the network is connected, and then open the editor. If unsuccessful, please make sure that Cocos Dashboard is using the latest v1.0.8, and completely exit and reopen. Minimizing the app isn’t good enough.

In addition, there is more good news: v2.4.1 already supports the Huawei AppGallery Connect platform, and developers can access Huawei HMS Core with one click, currently including account, Services such as payment, advertisement, and games will continue to support SDKs such as push, analysis and positioning in the near future.

Also, Cocos Creator will cooperate with Huawei in all aspects, especially at the technical level, integration with the underlying algorithms of CG Kit, tap Vulkan’s extreme rendering capabilities, release greater graphics rendering performance, and improve rendering efficiency. At the product level, Huawei’s HMS Core and AppGallery Connect will also be successively connected to more high-quality services to help developers develop higher-quality games.

Upgrade Tips

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Projects under development can usually be upgraded seamlessly, but because of the uniqueness of each project, developers should conduct a technical evaluation based on their project’s own needs. If developers encounter difficulties in upgrading, please feel free to give us feedback and we will try our best to assist. In addition, due to stability considerations, it is recommended that projects that are about to be launched or already launched be upgraded with caution.

Upgrade from <2.4.0 version

cc.loader is no longer recommended, please use the latest cc.assetManager instead, please refer to the Resource Management Module Upgrade Guide
The sub-package function has been upgraded to Asset Bundle, please refer to the Resource Subcontract Upgrade Guide
Adjusted the directory structure after the project is built and adjusted the API of BuildResults. If you use the editor plug-in to get the editor’s build results, please refer to Customized Project Build Process Upgrade Guide
The cc.RawAsset that was deprecated since 1.10 has been officially removed, please use cc.Asset instead. Since 2.4 is no longer compatible with the legacy usage of the RawAsset type in the original 1.x project, it is recommended that all projects to be upgraded to 2.4, especially those upgraded from version 1.9, be edited in any 1.10 ~ 2.3 version. All warnings or errors output when the compiler compiles the code are processed correctly, and then upgraded to 2.4.
cc.Color.fromHex is deprecated, please use cc.Color.fromHEX interface

Upgrade from < 2.3.3 version

The CCTexture2D and CCTexture2DRGB methods in the Effect have been abandoned.
Vec3.FRONT has been abandoned, please use Vec3.FORWARD instead.

Upgrade from < v2.3.0 version

Since v2.3.0, Android and Android Instant use the same build template, please note:

If the code is used solely by the Android platform, please put it in the app/src directory, and the third-party library used by itself, please put it in theapp/libs directory.
If the code and third-party libraries used by Android Instant are separate, please put them in the game/src, game/libs directories.
For code and third-party libraries shared by Android and Android Instant, please place them in the src and libs directories under the proj.android-studio root directory, respectively.
proj.android-studio under the root directory jni/CocosAndroid.mk, jni/CocosApplication.mk, mainly used to configure engine-related configuration, developer configuration, it is recommended that Android be placed in app/jni/Android.mk and app/jni/Application.mk, Android Instant, please put in game/jni/Android.mk and game/jni/Application.mk.
When Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling for Android Instant, it will execute instant: assembleRelease/Debug.

In addition, when Cocos Creator compiles for Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will executein``stant:assembleRelease/Debug.

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.


// Assuming testNode is a node in the scene, if it was manually removed

//from the scene before, such as

testNode.parent = null;

// or

testNode.removeFromParent(true);

// or

parentNode.removeChild(testNode);

// If testNode will be used again in the future, there is no need to

// manually destroy the node otherwise it should be called manually

testNode.destroy();

If a node is managed via cc.NodePool, it is not affected.

Cocos Creator v2.4.0 is here! This update brings more new features, optimizes performance and improves stability. Efficiency is everything! This version contains many new features and updates, such as resource management system refactoring, asset bundles, optimized the performance of graphic rendering.

It is recommended for all v2.3.x developers to upgrade! Please perform the necessary technical evaluation and backups before upgrading.

What’s New

If the worker wants to do his best, he must first sharpen his weapon! After two months of testing, version 2.4.0 is finally here! Thanks to all the friends who gave us valuable comments and suggestions!

Support Asset Bundles

Asset Bundle can divide the resources in a project into modules according to the wishes of the developer, and divide the resources with different needs in different scenarios into multiple packages. This reduces the time required to download and load a game for the first time, and can also be copied across projects.

Asset Bundle also provides priority, compression type and other related settings to optimize the package and loading of the Asset Bundle.

For additional details, please refer to the Asset Bundle documentation and the Load Asset Bundle documentation.

Added `cc.AssetManager` module for resource management

Asset Manager is newly introduced in Cocos Creator v2.4. It has the function to load resources, find resources, destroy resources, cache resources, asset bundles and so on. Asset Manager has better performance, easier-to-use APIs, and stronger scalability. It mainly provides the following new features:

Supports loading and pre-loading of all resources, pre-loading can run silently in a lighter way, without affecting operation efficiency.
Supports Asset Bundles.
Supports a more secure automatic release mechanism, no need to consider its reference when releasing resources, to avoid mistaken release of resources.
Support download failure retry, download priority, download concurrent number and other settings, which can be adjusted according to various situations.
Support more convenient custom loading process to achieve special effects.

For details, please refer to the Asset Manager documentation and the Dynamic Loading documentation.

Add Label blending options

Supports setting Label’s belnding options, and different settings in different usage scenarios can be used to maximize text rendering performance. For details, please refer to the Blending Mode of System Fonts documentation.

Use FreeType to render Label on native platforms

Increased Label initialization speed, Android increased by about 5 times, iOS increased by 3 times
Support bold, outline, shadow and other effects when using TTF font and Char mode

Support Graphic anti-aliasing effects

Using SDF technology to optimize Graphic’s aliasing problem:

Support the compressed texture of other small game platforms

The editor further supports the compression texture limitation of more mini game platforms. Just add the compressed texture format in the Mini Game item to set the compression of multiple platforms including WeChat mini games, OPPO mini games, Vivo mini games, etc.

Improve native hot update support

Cocos Creator v2.4 further improves the native hot update capability and optimize the following:

Add interface to get update package size
Add MD5 parameter to the link, more friendly to CDN

If you have customized the pause logic when switching between audio background and background, please remove it after upgrading to 2.3.0 Currently Cocos Creator games automatically pause and resume audio internally when switching between front and back on all platforms. If the developer has customized this block before, and listens for and performs audio operations like cc.audioEngine.pause() and resume(), it may conflict with the engine’s default behavior. If you encounter related audio issues, simply remove the corresponding custom code.

Upgrade from version v2.0 – v2.3.0

Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0

Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.

In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.

If a node is managed via cc.NodePool, it is not affected.

An error will occur when importing Cocos Studio projects into Cocos Creator v2.3.2. This issue will be fixed in v2.3.3. Developers can temporarily import the project into an old version, if needed, and then upgrade to v2.3.2 for use, or use a custom engine and incorporate this change [#6278]

Deprecation

Starting with v2.2.0, we no longer recommend using the Skew feature of Nodes. Skew is usually used to simulate 3D effects in 2D engines. With Cocos Creator’s in-depth support for 3D nodes, Skew effects can be completely achieved by using 3D nodes. Backward compatibility will be maintained for a period of time, developers can continue this original practice, in the old project. In the future, we will further improve the compatibility method and upgrade cases, and officially choose to remove the Skew function.

Upgrade Tips

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Projects under development can usually be upgraded seamlessly, but because of the uniqueness of each project, developers should conduct a technical evaluation based on their project’s own needs. If developers encounter difficulties in upgrading, please feel free to give us feedback and we will try our best to assist. In addition, due to stability considerations, it is recommended that projects that are about to be launched or already launched be upgraded with caution.

Upgrade from < v2.3.0 version

If a Can not find module.module for path… loading warning occurs:

After upgrading to 2.3, this warning may be due to the stricter case detection of the import/requirepaths in the script. In the old version, if the case of the path does not match the actual file, there may be some potential errors which may not be manifested. We recommend that projects experiencing this issue correct the capitalizations.

Since v2.3.0, Android and Android Instant use the same build template, please note:

V2.3.0

Publish Time: 2020.02.16

After a long period of development and preparation, and after a memorable Spring Festival, Cocos Creator v2.3 is officially released. v2.3 is a very important version that officially integrates support for 3D physics, collisions, and 3D particles, and is capable of developing more types of 3D games! At the same time, the material system has been upgraded from the experimental version to the official version, which can greatly improve the expressiveness of a game. It is recommended that all developers upgrade! Please perform the necessary technical evaluation and backups before upgrading.

Support publishing to Qutoutiao (QTT) mini games

Cocos Creator v2.3 officially supports publishing to a brand new platform: Qutoutiao Mini Games. For detailed steps on platform access, please refer to Publish to Qutoutiao Mini Games.

Support 3D physics system

Like Cocos Creator 3D, Creator’s physics engine is based on cannon.js and provides users with an efficient, componentized workflow with convenient usage methods. Currently, supported functionality is: rigid body, Box/Sphere collision components, trigger and collision events, physical materials, ray detection and many other features.

For detailed information, please refer to the Physics 3D documentation.

Supports 3D collision system

Like Cocos Creator 3D, Creator provides a lightweight collision detection system called Builtin. Builtin is a physics module with only a collision detection system. Compared to other physics engines, it does not have complicated physics simulation calculations, which will make the game’s package smaller and provide better performance.

For detailed information, please refer to the Physics Select documentation.

Support 3D particle system

The implementation of 3D particles is basically the same as Cocos Creator 3D. It is powerful and supports debugging in the editor.

There are currently dozens of modules to choose from, including Shape, Color, Velocity, Size, Sequence Frame, Trailing, and so on.

Currently provided are a variety of parameter settings such as: Constant, Curve, Two Constant, Two Curve, Gradient, etc.

For detailed information, please refer to the Particle System 3D documentation.

Upgrade the material system to the official version

Creator’s material system was originally added in v2.1.1, but has been marked as an experimental feature in the editor and lacked relevant documentation. After a few iterations, it has upgraded to the official version! This version of the Effect compilation syntax is consistent with Cocos Creator 3D. It can be written using VS Code’s Cocos Effect plugin, but the built-in shader variable names are slightly different. Developers who have customized materials in the previous version of Creator can try to upgrade to the official version according to the documentation. If you encounter difficulties, you can post on the forum for help. The features of the new version of the material system are as follows:

Support real-time preview of modified results in the scene when modifying materials.
Supports material variants and effect variants, making it more friendly to 2D games.
Supports multiple techniques.
Supports setting Technique, Pass, Property names.

For detailed information, please refer to the Materials documentation and the Effects documentation.

Support Spine and DragonBones mount nodes

When playing skeletal animations, developers often need to mount nodes on a certain part of the skeletal animation to achieve the effect of linking the node with the animation. In Creator v2.3, only a single, very simple operation is needed to mount any node to the bone animation. The node will follow the animation and transform it to achieve the effect of the hanging point. You can also add collision components to the node to achieve collision detection!

For detailed information, please refer to the Spine documentation.

Support Spine binary resource format

In Cocos Creator v2.3, the Spine runtime was upgraded to v3.8. v3.8 supports the skel binary format for importing from Spine. The usage of the skel format is the same as the original JSON format, but the file is smaller and loads faster!

Only recompile scripts when building

In the build panel, if you have successfully built the project before, you can check Build script only for the second build. The checked build will reuse the engine and resources that were built last time, and only recompile the scripts, which will greatly facilitate debugging! This is a very popular feature in the community, thank you very much for suggesting it.

BREAKING CHANGES

cc.Mat4.translate method no longer supports rotation transformation, only pure displacement transformation is supported. If you need to support rotation, please usecc.Mat4.transform instead.

KNOWN ISSUES

Requiring node_modules directly is not available in v2.3.0 temporarily. It will be fixed in the next version. It is currently recommended that external libraries be compiled separately and imported using the Plugin Scripts.

Deprecation

Starting with v2.2.0, we no longer recommend using the Skew feature of nodes. Skew is usually used to simulate 3D effects in the 2D engine. With Cocos Creator’s deep support for 3D nodes, the Skew effect can be completely realized by 3D nodes. Inorder to unify the user experience and further optimize the underlying implementation of the engine, we discarded the Skew attribute. However, we will still maintain backward compatibility for a period of time, developers can continue the original practice in the old project. In the future, we will further improve the compatibility method and upgrade cases, and officially choose to remove the Skew function.

Upgrade Tips

Upgrading a project from a previous version of Cocos Creator is irreversible. Please backup the old version of the project before upgrading.

Projects under development can usually be upgraded seamlessly, but because of the uniqueness of each project, developers should conduct a technical evaluation based on their project’s own needs.

When Cocos Creator compiles Android, it will execute assembleRelease/Debug by default, and when compiling Android Instant, it will execute instant: assembleRelease/Debug.

Upgrade from version v2.0 - v2.3.0
Starting from 2.3.0, the Canvas component is no longer responsible for setting the Canvas node size to the screen size. This behavior will be implemented in conjunction with the Widget component. To ensure compatibility, after the 2.0 project is upgraded, the node where Canvas is located will automatically add Widget components. (No problem upgrading from a 1.0 project)

Upgrade from < v2.2.0
Starting from 2.2.0, we have strengthened the memory management mechanism, and now require users to dynamically create cc.Node which is independent of the scene node tree through code must be released through destroy(), otherwise the engine cannot know when to recycle this type The memory of the node will cause a memory leak.In addition, the nodes that are manually removed from the scene need to be unified when they are not needed.

The game engine plug-in is a new feature of WeChat version 7.0.7. This can greatly reduce the download time of games. This plug-in is now integrated into Cocos Creator v2.2.1 as part of the environment and will be more convenient to use. Developers only need to check Allow engine separation in the Build panel, and then build the release normally, without any other manual operations.

For more information, please refer to《WeChat Engine Plugin》.

Upgrade Instructions

If you open the 1.x project, all resources such as the scene will be automatically upgraded. If there is a warning or an error, please refer to 1.10.0 Resource Upgrade Guide and 2.0.0 Upgrade Documentation to make adjustments.
2.0, 2.1 Projects can be upgraded directly and seamlessly.
Starting with 2.2, we have enhanced the memory management mechanism. Now the cc.Nodethat is dynamically created by the code and independent of the scene node tree must be released by destroy(), otherwise the engine doesn’t know when to recycle such nodes. In addition, nodes that are manually removed from the scene need to unify destroy when they are not needed. If the node is managed via cc.NodePool, it is not affected.

    // Suppose testNode is a node in the scene, if it was manually removed from the scene, such as
    testNode.parent = null;
    // or
    testNode.removeFromParent(true);
    // or
    parentNode.removeChild(testNode);
    // If testNode will be used again later, there is no need to manually destroy the node.
    // Otherwise it should be called manually
    testNode.destroy();

V2.2.0

Publish Time: 2019.10.18

The Cocos Creator team has been hard at work ensuring that your games perform very well on each platform we support. Cocos Creator v2.2.0 greatly enhances the performance of the native platform, and includes a large number of feature enhancements and experience improvements. All Cocos Creator developers should consider upgrading to this latest version.

Greatly improve native platform rendering performance

In this version, we have significantly upgraded the rendering engine and achieved tremendous performance improvements on native platforms, surpassing the speeds of all previous versions of Cocos Creator, Cocos2d-js and Cocos2d-x.

Cocos Creator v2.2 can meet all the performance needs of every game, small to large, simple to complex, few gaphics to 1,000’s of graphics. To help gauge performance, low-end devices, such as the OPPO A57 and the iPhone 6S+ were used. We also compared previous versions of Cocos Creator, Cocos2d-js, Cocos2d-x and Cocos2d-lua to ensure we were testing in a broad spectrum, to provide the most accurate data. The results:

On Android native, the performance of Cocos Creator v2.2.0 is 1.5x - 1.7x Cocos2d-lua and Cocos Creator v1.9.3.
On iOS native, the performance of Cocos Creator v2.2.0 is flush with
Cocos2d-lua, which is 3x - 4x Cocos Creator v1.9.3.

In addition, Cocos Creator v2.2.0 running on iOS not only improves the frame rate, but also greatly reduces any possibility of jittering when garbage collection occurs. This means the actual game play experience will be really smooth. Here is detailed performance data：

Support 3D model rendering batch

Cocos Creator v2.2.0 adds support for rendering batches of 3D models, which effectively reduces the drawcalls for 3D games. To enable this feature, you simply check the enableAutoBatch attribute on the Mesh Renderer and the engine will automatically batch based on the material used, as well as the Mesh vertex format and Primitive Type. For better optimization, it is recommended that you enable this option only for models that can be batched and have a small number of vertices.

Support for alpha channel separation of PVR compressed textures

Alpha channel separation format (RGB+A) for PVR compressed textures has been added. This format uses a similar method to etc. to separate and compress the transparent channel of the texture. After compression, the texture height will be twice that of the original image, thus avoiding the problem of low image quality in the conventional PVR RGBA format.

Support for custom browser preview templates

Allow users to customize the webpage used for browser preview in a way similar to custom build templates. Support for 3 formats: HTML, Jade, EJS. See: Custom Preview Templates.

Support for ambient light settings

We have added an ambient light setting to the Light component for basic lighting of 3D scenes. This is often used to solve the problem of blackout of the back surface of the model. Just select Create Light → Ambient in the Node creation menu. You can also add a Light component to the Node and set the type to be created for AMBIENT.

Further improve the performance of Spine and DragonBones

Cocos Creator v2.2.0 optimizes the performance of 2D skeletal animation on various platforms.

On the native platform, we have added support for Spine and DragonBones SHARED_CACHE and PRIVATE_CACHE. When the acceleration mode is enabled, the Spine performance of the Android platform is 2x that of the original, and the DragonBones performance
is 7x the original. iOS platform Spine performance is 3x the original,
DragonBones is 5x the original.
After enabling acceleration mode on the web platform, Android Spine performance is 3x the original, and DragonBones performance is 4x the original. iOS Spine performance is 1.25x the original, DragonBones performance is 1.39x the original.

Here is a breakdown of the detailed performance data:

To enable acceleration mode, simply set the Animation Cache Mode to SHARED_CACHE or PRIVATE_CACHE on the Spine or DragonBones component. For more detailed information acceleration mode, refer to the property descriptions in the documentation.

Spine runtime upgraded to 3.7

Support Spine partial reloading, please refer to Spine Component Reference, see SpineSkin in the engine’s own example.
Support Spine vertex effect, please refer to Spine Component Reference: Spine Vertex Effect, please refer to SpineMesh in the engine’s own example.

Significantly enhanced TiledMap support

Cocos Creator v2.2.0 further improves the support of TiledMap. Grid rotation, grid animation, image layers, layer offsets, and object group text are now supported. Supporting multiple Tilesets in a single layer is also now possible. It also supports adding child nodes to the scene and creating an occlusion relationship with the map. And fixed the problem of rendering errors after a single map vertex exceeds 65535. For details, see TiledMap Component Reference. For details on use cases, see ShieldNode in the engine’s own example.

Property inspector tag supports width adjustment

We added a width adjustment function to the Property inspector to solve the problem of incomplete display of attribute names on some components. Now users do not need to greatly adjust the size of the entire panel, just drag the dividing line to the right of the property name to freely adjust the split ratio.

V2.1.2

Publish Time: 2019.07.17

Six months has passed since the release of Cocos Creator v2.1.0, and the team has been hard at work creating the next releases. Cocos Creator v2.1.0 is our most popular release to date. The development teams effort will be spent on Cocos Creator v2.1.0 and therefore maintenance of v2.0.xwill be discontinued. v2.0.x users should consider upgrading to v2.1.1 when it makes sense to do so.

The v2.1.2 update includes not only general experience optimizations and bug fixes, but also the optimization of pure 2D projects, as well as a decrease in project size. At the same time, this version also incorporates all the changes in v2.0.10, supporting the two new platforms: Xiaomi Mini Gamesand Cocos Play.

Optimizing 2D projects

Previously we had always positioned v2.1 as a 3D predecessor, so v2.1 was lagging behind for the care of pure 2D projects. However, v2.1.2 has been carefully optimized to work well with both 2D and 3Dprojects. Now we officially recommend that all v2.0 projects be upgraded to v2.1.2. Projects upgraded from v2.0 will default to 3D modules, ensuring that there is no impact on the package and performance of 2D projects. To add 3D support, manually check the 3D module in Menu → Project → Project Settings → Module Settings.

Supports Xiaomi Mini Games

Cocos Creator officially supports publishing to Xiaomi Mini Games. For detailed usage, please refer to Publish to Xiaomi Mini Game.

Supports Cocos Play

V2.1.1

Publish Time: 2019.04.30

Since the release of Cocos Creator 2.1.0, we have received a lot of valuable suggestions from users. Based on previously announced plans, we will continue to speed up the iteration of the v2.1 series to implement user suggestions as quickly as possible. At the same time, in order to prevent these changes from affecting the stability of old projects, we only recommend upgrading projects with 3D requirements to v2.1. Other projects can continue to use v2.0, and wait until v2.2 is released before upgrading. This v2.1.1 upgrade mainly supports 3D scene editing, camera preview, lighting system, and also incorporates the latest 2.0.x changes.

Support 3D scene editing

The Scene Editor allows you to switch to 3D editing mode with one click, making it easy to edit 3D objects, cameras, and lights. See the 3D Scenes document 1 for details.

Add game preview panel

A separate preview panel has been added to visually preview the images seen by the camera during scene editing. Panel Open: Main Menu → Panel → Game Preview, the preview panel can be placed in a separate window or dragged into the main editor window.

Upgraded EditBox component

Now, developers can set the Text Label, Placeholder Label and Background nodes separately, making them more flexible, simple, and more in line with the component development. See the EditBox Component Reference documentation.

Add text shadow rendering component

A new LabelShadow component has been added to add a shadow effect to the Label component, similar to the LabelOutline usage. See the Label Component Reference documentation.

Support for dynamically creating 3D Primitive models

Added cc.primitive module to dynamically create 3D models at runtime, including: box, cone, cylinder, plane, etc. See the Basic 3D Objects documentation.

Integrated Material System (Beta)

Added support for material systems, allowing users to create Material and Effect (Shader) resource types. It should be noted that the current material system is mainly provided to the internal use of the engine and is only for developer preview. We plan to upgrade the material system in v2.1.2, however it will not be back-ported to this version.

Editor Fixes

Follow-up version notice

v2.0.7 will be released soon, focusing on optimizing native platform performance

We will soon be beta testing v2.0.7. In this version we optimized the rendering performance of the engine, especially the Spine and DragonBones of the native platform, and the performance has been greatly improved.

v2.1 iterations will be more aggressive

Compared with v2.0, the upgrade of v2.1 will mainly focus on the 3D field. We recommend upgrading new projects with 3D requirements to this version, and establishing contact with us in forums and other channels. Our responsible 3D partners will provide relevant support. . Since v2.1 is a very new version, we will speed up the iteration and try to meet the needs of developers. We will be releasing v2.1.1 in the near future to support 3D scene editing, camera preview and material systems, and to optimize the 3D development process.

WINDOWS MAC

2018.11.05

V2.1.0

Publish Time: 2018.11.05

Cocos Creator v2.1, adds support for 3D features such as: 3D model rendering, 3D Camera, 3D skeletal animation, and 3D point selection. The Cocos Creator editor now natively supports parsing 3D model files in FBX format. It’s that simple, no additional workflow is required!

In the previous version, v2.0, Cocos Creator had used a Cocos3D based 3D renderer to officially introduce 3D support. The addition of 3D features can greatly enrich the expressiveness of 2D games, reduce the resource overhead of 2D games, and bring more imagination and ideas to expand games.

However, it should be emphasized that the target users of Cocos Creator is still 2D game development, and the 2D game is still the core service of Cocos Creator 2.x. We will continue to optimize the development experience and basic performance of 2D games, and gradually increase the 3D functions suitable for integration into 2D games. Therefore, Cocos Creator does not allow a pure 3D game, which is the goal of Cocos3D. Cocos Creator’s development path is closer to 2.5D.

This is not the first time Cocos has upgraded the engine from 2D to 3D. A few years ago, Cocos2d-xexpanded to the 3D space and accumulated a lot of experience. It also produced a very good game concept like Sword and Home. However, at that time, 3D functions were piled up on a very heavy 2D renderer, and there was no editor support. It was not widely recognized by the market. This time, Cocos Creator is based on Cocos3D’s 3D renderer, which has a lot of 3D stability and guarantees a seamless editor experience.

Follow-up Version Notice

v2.0 will continue to be maintained, native platform performance will be optimized as soon as possible

v2.0 and v2.1 will grow together over a period of time.v2.0 will continue to be maintained, adding more performance optimizations and bug fixes. We will soon be beta testing v2.0.7. In v2.0.7 the rendering performance of the engine has been optimized, especially Spine and DragonBones. Also, the performance has been greatly improved.

v2.1 iterations will be more aggressive

Compared with v2.0, the upgrade cycle of v2.1 will mainly focus on 3D features. We recommend upgrading new projects with 3D requirements to this version, and establishing contact with us on our forums. This allows us and our 3D partners to provide support.Since v2.1 is a very new version, we will speed up the iteration and try to meet the needs of developers. In particular, currently v2.1.0 version still does not support 3D scene editing, only the 3D parameters can be set in the property inspector. We will be releasing v2.1.1 in the near future to support 3D scene editing, material systems and optimizing the 3D development process.

Complete list of changes (compared to v2.0.5)

3D Node

In v2.1, newly created Node objects are still 2D by default. When needed, you only need to click the 2.5D button at the top right of the Node to switch to 3D mode. After switching, you can edit the z axis. See 3D Node .

3D Camera

Like Node, Camera is also divided into two modes. When you add a Camera component to a normal 2D node, it becomes a 2D Camera. When you switch Node to 3D mode, Camera will also enter 3D mode, and then you can edit Camera's FOV and other parameters in 3D mode.

3D model import

Currently, Cocos Creator supports importing 3D model formats for a very wide range of .fbx files. .fbxis the de-facto standard in 3D modeling software. The process of importing is very simple, just drag the .fbx model into the Explorer and wait a few moments for the import to complete. After the import is completed, you can see that the imported model is a folder that can be expanded in Explorer. When importing the model, the editor will automatically parse the content of the model and generate a Prefab, a Grid, a Bone Animation and other resources. See Import Models

s_D5EB83DE4EB14ED7F4E0412694594BEA563C6F613AB6CAC04191666891BDD83C_1543326015234_image

Mesh Renderer Component

Mesh Renderer is used to draw grid resources. See Mesh Renderer .

Bone Animation Component

The Skeletal Animation component inherits from the Animation component. The Skeletal Animationcomponent is not much different from the Animation component. The exception is the Skeletal Animation component uses a clip that can only be a Skeletal Animation clip. The Skeletal Animationcomponent is automatically added to the model’s Prefab when it is imported. See Bone Animation Component for details.

For more 3D instructions, please consult the documentation 3D System .

Optimize automatic gallery build speed

v2.1 greatly optimizes the speed of auto-atlas construction. If the atlas has not changed, the results of the last build are used.

Further improve rendering performance

Between v2.0 compared to v1.x, there are some cases where the engine does not render batches, resulting in an increase in draw calls. v2.1 re-optimized these conditions. If the previous color or opacity cannot be batch processed, sliced and non-sliced share the same texture and cannot be batched. The problem that the opacity 0 node still occupies the draw call is solved.

Add simulator debugging function

In the Project Settings -> Preview Run Panel, the Open simulator debugger panel option and the Wait for debugger connect option have been added. The purpose of the Open simulator debugger panel option is to automatically open the debug window when the simulator previews the project. The Wait for debugger connect option is used to suspend the boot process until the debugger connection is complete for debugging the load process.

s_D5EB83DE4EB14ED7F4E0412694594BEA563C6F613AB6CAC04191666891BDD83C_1543327279764_image

Texture Auto Compression

The compression required by the texture can be set directly in the editor, and Cocos Creator will automatically compress the texture when the project is published. Exporting multiple image formats simultaneously on the web is supported. The engine will automatically download the appropriate format according to the different browsers. See Compressed Textures for details.

Enhancements

Editor

Dashboard is closed when the project is opened, and automatically opened when the project is closed.
Dashboard will automatically record the last created project path.
Optimize the preview of the Button under the editor.
Optimize the way Button Click Event indexes components, avoiding the loss of indexes after scripts are renamed.

V2.0.4

Publish Time: 2018.10.18

The Playtime Conference hosted by Google Play was held in Germany on October 18th, 2018. The BIG NEWS: In partnership with Google, Cocos Creator v2.0.4 was released, supporting Google Play Instant games.

Google Play Instant and Cocos

In March of this year, Google showed Google Play Instant, a game store-based distribution solution called Search Instant. For the player, they are allowed to try the game before deciding to download the full version of the game, which greatly saves their device storage space. For developers, it means they can offer a demo experience to players who wouldn’t have installed these games, which in turn will increase the game download conversion rate.

Google Play Instant offers a higher APK size limit (10MB), support for progressive downloads for both executable code and game assets, allowing developers to use the NDK and game engine with existing toolchains. In order to make instant apps and games easier to build, as a Google Play Instanttechnology access partner, in May of this year, the Cocos engine began to do integration testing with Google and beta users of the Cocos community.

Developers only need to select Google Play Instant as the publishing platform to automate all technical docking of the Google Play Instant platform. The output is compatible with Google Play Instant. Technically-standard games, quickly launched on Google Play Instant for testing, greatly reducing development costs.

Release Notes

v2.0.4 only adds Google Play Instant Support, no other changes from v2.0.2.

V2.0.0

Publish Time: 2018.08.03

After a large-scale underlying refactoring and a two-month stability iteration, Cocos Creator v2.0 is finally available. The core goals of the Cocos Creator v2.0 design were twofold:

Significantly improve the engine performance
Provide more advanced rendering capabilities and richer rendering customization’s

In order to accomplish this goal, we completely rewrote the underlying renderer, which structurally guarantees performance improvements and upgraded rendering capabilities. At the same time, in order to ensure that user projects can be upgraded more smoothly, we have almost no changes to the API of the component layer. Of course, these changes are not completely transparent to the user, such as the engine loading process, the event system, the streamlining and reorganization of the engine’s overall API, which will have an impact on the user-level API.

Editor

Implemented premultiply alpha, filter mode, wrap mode configuration of Texture
Abstract the mixed mode configuration into the RenderComponent component base class, all render components can be configured
Camera component upgrade, as a direct rendering entry, you can configure various base rendering parameters
With Quick Compile integration, the custom engine only needs to use the menu’s developer options -> compiler engine to compile quickly in a matter of seconds
Open the WeChat game open data domain as a publishing platform with a separate publishing panel

Engine

Add a new renderer based on the 3D engine
Render component is fully upgraded
Remove the render tree completely, assemble the render data directly and submit the render by the render component
Streamlined cc namespace API
Streamline Director API
Camera component upgrade
Start process upgrades, user scripts and plugin scripts can more easily interfere with engine initialization
Platform-specific startup code is separated and easier to customize
Event system optimization, distinguishing between system events dispatched by the capture bubbling mechanism on the node tree and normal events directly dispatched
Fit Width & Fit Height is also compatible with the WeChat game platform.
The RenderTexture resource type has been officially added to save the rendered content captured in the camera.
Simplify TiledMap functionality to pave the way for subsequent upgrades
Physical engine upgrade, performance optimization

Deletions and deprecations

A large number of private and non-core APIs for v1.x have been removed or discarded. For details, please refer to the upgrade guide and deprecated
