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 < 2.3.3 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.

Upgrade from < v2.0

If you open the 1.x project, all resources such as scenes will be upgraded automatically. If there are warnings or errors in the code, you can refer to v1.10.0 Resource Upgrade Guide and the v2.0.0 Upgrade Documentation.

Just in case

Note: If you prefer not to use Dashboard now, you may still download Cocos Creator v2.3.4 for MacOS and Windows.

Cocos Creator v2.3.3 is here! This update brings more new features, optimizes performance and improves stability. Efficiency is everything!

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

Support PCF soft shadow

Starting from v2.3.3, the Light component can set the shadow type to SOFT_PCF3X3 or SOFT_PCF5X5 to turn on soft shadows. After opening, the shadow will not have hard edges, the effect is more soft and natural.

Support zooming Sprite by 9-sliced SpriteFrame in TILED mode

Starting with v2.3.3, the image will be repeated to fit the size of the Sprite when using TILED mode. If the SpriteFrame is 9-sliced, the corners will also remain unscaled while the other areas will be repeated.

Improve web page loading speed during preview

In order to further improve development efficiency, we optimized the loading speed of scripts during web page preview in both the engine and in project code. When the custom engine feature is turned on, or when using a mobile phone to preview, developers get a really smoother experience.

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.

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. 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
  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 inapp/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 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. If a node is managed via cc NodePool, it is not affected.
  
  // 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();

• Upgrade from v<2.0
  If you open the 1.x project, all resources such as scenes will be upgraded automatically. If there are warnings or errors in the code, you can refer to v1.10.0 Resource Upgrade Guide and the v2.0.0 Upgrade Documentation.

Cocos Creator v2.2.2 is intended to fix defects and improve product stability. Please see below for a subset of improvements.

Version Updates

Cocos Creator v2.2.1 is coming soon. please view the Welcome Experience topic. This version will integrate Alipay games.

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 reference documentation
• Dragonbones reference 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.

Improvements

• Optimize the editor and the startup speed of each panel
• Avoid every time the WeChat game build will overwrite the configuration file in the target project in order to retain the user’s custom configuration
• Change the margin property in the SpriteFrame resource panel and Sprite Editor from the trimmed margin to the original margin. Make it consistent with the data given in the art drawing, and have no effect on the old project data.

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.

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.

Add 3D lighting and shadows

A Light component has been added to lay out lights in the scene, and a shadow effect can be set in conjunction with MeshRenderer. See the Light Source Component Reference documentation.

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

• Added shortcut Ctrl/Cmd + Shift + F to align the currently selected node to the perspective of the scene editor.

At the same time, we have further improved the compatibility and stability of the engine and editor, so that everyone can get a better development experience. Good quality is inseparable from careful polishing. Thanks to the feedback from developers on the community, GitHub, Cocos corporate services and other channels.

Improving the performance of DragonBones and Spine on non-native platforms

Cocos Creator v2.0.7 greatly optimized the performance of DragonBones and Spine on native platforms, with performance optimized to more than twice as fast as 1.9 and 1.10. This release, v2.0.9, for Web platforms and non-native platforms. SHARED_CACHE and PRIVATE_CACHE acceleration modes, have improved DragonBones performance by 15 times, and Spine’sperformance has improved by 3 - 6 times.

Performance test results after acceleration mode is enabled:

• The score of the test is converted from the frame rate and the number of animations. The higher the value, the better the performance.

When playing more than three animations on the same screen, SHARED_CACHE acceleration mode can also greatly reduce memory overhead. The following is a memory comparison of one hundred animations on the same screen:

• The lower the score of the test, the less memory is occupied. The more animations SHARED_CACHE saves more memory.

To enable Extreme Mode, simply set the Animation Cache Mode to SHARED_CACHE or PRIVATE_CACHE on the DragonBones or Spine components. For more detailed information on speed modes, refer to the Dragonbones reference documentation and Spine reference documentation.

Support for publishing as Android App Bundle

In Build panel, publishing to Android App bundles has been added. When checked, Android native games can be published as App Bundles. After submitting the App Bundle to Google Play, Google Play will dynamically download different versions of the APK based on the differences in the player’s phone parameters to reduce the game’s package size.

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.

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

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.

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.

Resources

• Creator v2.0 API docs
• v1.10 Resource Upgrade Guide 

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.

Documentation is here.

Compared to v1.9, the v1.10 version adds a lot of features, refactoring the resources of the engine, and greatly optimizing the size of the settings.js file. In addition, v1.10 also supports game code subcontracting on WeChat games, web and native platforms. This will break through the 4MB limit of WeChat’s first package and increase the game loading speed. See Code Subcontract Loading . At the same time, v1.10 has rewritten a lot of editor code, improving the editor’s experience and performance. If your project is planned to be upgraded to v2.0 later, please upgrade to v1.10 in advance to ensure that the entire upgrade process is as smooth as possible.

v1.10.1 is a bug fix for the recently released v1.10.0. It is recommended that all v1.10 users update to this version. This version is not an alternative to v2.0, v2.0 is still the current version, and new projects are still recommended to use v2.0. As the last major version before v2.0, we will try our best to maintain stability until we can support users who are temporarily unable to upgrade to v2.0.

Good quality is important to us. Thank you very much for the feedback from developers through the forum, GitHub, Cocos technical services and other channels. Let us look forward to the upcoming 2.0.1!

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

QQ Play Known Issues:

At present, QQ Play is still in AB Test. Developers are also required to obtain internal beta qualification in order to develop, and currently only support compiling on Mac. In addition, our adaptation work on QQ Play has not been completely completed yet. The following modules are still not supported at present:

• Label: ttf is not supported, system font can only use the default font
• Particle system: Map data is not supported in plist. Only texture urls are supported.
• WebView
• VideoPlayer
• DeviceMotion

The above functions are expected to be supported one by one in future updates. We will also continue to closely communicate with QQ Play’s engineers to continuously optimize the matching effect.
