Cocos Creator v3.4.1 released!

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

  1. Refactored 2D batching strategy, RenderData holds static VertexBuffer memory to optimize 2D rendering performance on all platforms

  2. Optimize the state management of 2D rendering components, and change the UV and Color to fill immediately to avoid polluting the VB state

  3. Material.copy now supports accepting override material modification parameters

  4. Enable WebGL 2.0 on WeChat to prepare for future WeChat versions that support WebGL 2.0

  5. Slightly optimize the performance of the particle system

  6. Fix the problem that the editor with too many startup scripts is slow

  7. Fix the problem that an error will be reported when compiling the simulator

  8. Limit the maximum device pixel ratio of the web platform to 2, and fix the performance degradation caused by it

  9. Fix event dispatch priority so that UI listeners always take precedence over input event listeners

  10. Fix the problem of performance degradation in shadow collection logic

  11. Fix the problem of abnormal exit when restart is called for the second time in iOS/macOS

  12. Fix the problem that the game logic stops when the Android platform enters the background

  13. Fix the problem of independent use of SkeletalAnimation sample API

  14. Fix the confusion problem of animation crossFade API

  15. Fix the color setting problem of TiledLayer

  16. Fix the problem that multiple camera outputs are overwritten when rendering to the same RenderTexture

  17. Fix some memory fragmentation issues on the native platform

  18. Fix the problem that Label spacingX property is not serialized

  19. Fix the problem that the profiler disappears after restarting in debug mode

  20. Fix the problem that burst does not behave correctly after replaying after pause

  21. Fix the problem that the UseHDR button has the opposite effect when switching scenes

  22. Fix iOS & Mac Safari does not support USE_REFLECTION_DENOISE

  23. Fix the problem of performance degradation introduced by getSystemInfoSync on Cocos Play and WeChat platform

  24. Fix the problem that Sphere Light doesn’t work correctly on Android Web

Known legacy issues

  1. Slider cannot be smoothly dragged in ScrollView: solution planned in v3.4.2

  2. SkeletalAnimation directly setTime is invalid without calling play Solution in v3.4.2

  3. 2D particles flicker in some cases: Solution in v3.4.2

  4. DragonBones needs to call ArmatureDisplay.markForUpdateRenderData after setting the position to update correctly: Solution in v3.4.2

  5. Potential crash in Android 12 with Vulkan backend: Solution in v3.4.2
