Version 3.2.0 Release Changelog

Bug Fixes

Engine

  1. Fixed the issue where 3D video textures were displayed incorrectly on the Native Android platform in OpenGLES mode.
  2. Fixed the error caused by the unsupported spine.PathAttachment.
  3. Fixed the bug where a part of the image was missing, and the animation could not play after using path constraints in Spine.
  4. Fixed the display anomaly when the number of Spine bones exceeded 100.
  5. Fixed the error in Spine caused by using the loading timing in the onEnable lifecycle.
  6. Fixed the flickering issue in Spine animation frames.
  7. Fixed the position offset bug caused by setting both filters and anchor points simultaneously.
  8. Fixed the bug where video nodes could not play in Native standalone packages.
  9. Fixed the bug where the 3D navigation navAgent.getCurrentPath() interface reported an error.
  10. Fixed the bug where the engine would freeze if the nine-slice data was unreasonable.
  11. Fixed the bug where the first click on a PC touch screen triggered onmouseclick twice.
  12. Fixed the bug where setting the speed of a 2D animation to a negative value caused incorrect event calls.

IDE

  1. Fixed the issue with particle curve editing.
  2. Fixed the bug where selecting multiple UI components and dragging them to change the X/Y values of the bounding properties in the properties panel would misplace the UI components.
  3. Fixed the bug where FBX animation files exported from 3D Max could not play because the start time was not at frame 0.

Updates and Optimizations

  1. New: Added the strikethrough text feature.

  2. New: Added a package manager.

    Note: Package manager import and management is supported only when the package contains package.json and has the relevant fields configured.

  3. New: Added the ability to set the entry function:

    Note: This script must export a function named main. After the engine initializes, this function will be called directly, and the default scene will not be opened. Developers can decide which scene to open within the entry function.

  4. New: Added support for using the engine's WASM library on the WeChat Mini Game platform.

  5. New: Added support for scene hooks, allowing custom logic insertion in specific processes like creating, loading, or saving objects in the scene. For example, if you want the pivot of all newly created UI nodes to initialize at (0.5, 0.5), you can write a plugin like this:

    @IEditorEnv.regSceneHook()
export class TestSceneHook implements IEditorEnv.ISceneHook {
    //载入场景后调用
    onLoadScene() {
    }
	//保存场景后调用
    onSaveScene(scene: IEditorEnv.IGameScene, data: any) {
    }
	//新建节点对象后调用
    onCreateNode(scene: IEditorEnv.IGameScene, node: Laya.Node) {
        
        if (node instanceof Laya.Sprite)
            node.anchorX = node.anchorY = 0.5;//初始化锚点
    }
	//场景中创建组件后调用
    onCreateComponent(scene: IEditorEnv.IGameScene, comp: Laya.Component) {
    }
}

  6. New: Added the option to include or exclude source code when generating source maps during release.

  7. New: The script collection feature now correctly isolates the code between different script collections. During development, scripts from different collections can be imported directly. The IDE will automatically convert these imports into indirect references during compilation to achieve bundle splitting.

  8. New: Script collections can now choose whether to load before the main script collection.

  9. New: The release interface now supports setting the main package as remote.

  10. New: Spine resources can now be dragged directly from the asset library to the hierarchy or scene, automatically creating Spine render nodes and Spine components.

  11. New: Added support for preset texture types. Since the default value sets imported textures as 3D textures, for 2D projects, this can be changed to sprite textures, eliminating the need for manual adjustments. UI components can now automatically recognize them as 2D sprite textures.

  12. Optimization: When using the 2D empty project template, the default texture type is automatically adjusted to sprite texture, making it more user-friendly.

  13. Optimization: After adding engine components, the corresponding engine libraries are automatically referenced to avoid runtime errors caused by missing engine libraries.

  14. Optimization: Added destruction detection for Spine nodes to prevent errors caused by asynchronously loading already destroyed nodes.

  15. Optimization: Performance improvements for handling a large number of files when using caching on the WeChat Mini Game platform.

  16. Optimization: Improved the efficiency of Native standalone packages, reducing the initial black screen time.

  17. Optimization: Resource management no longer generates meta files for all files in node_modules folders or files and folders ending with “~”.

  18. Optimization: If developers choose to use WASM libraries from the engine modules, such as physics and navigation, the platform will automatically switch to the corresponding pure JS library for platforms that do not support WASM.

  19. Optimization: The build task interface has been changed from a dialog box to a panel.

Major New Features

  1. Added a visual programming module (Blueprint).
  2. Added support and build publishing for the HarmonyOS NEXT platform.

General Updates and Optimizations

  1. Removed Spine from widgets. Starting from version 3.2, the node mode for Spine is no longer supported and has been replaced with the Spine skeleton animation component.
  2. Improved engine performance, especially noticeable in iOS environments.
  3. Added useFrame and updateFrame properties to videoTexture for optimizing video playback, addressing video playback stutter issues in the Android WeChat browser.
  4. Added support for simultaneous touch screen and mouse operations on laptops that support both inputs.

  6. Deprecated the drawToTexture interface in Sprite, replacing it with the drawToRenderTexture2D interface.
  7. Changed the ES5 conversion function in Alipay mini-game publishing to be built into the IDE, no longer using Alipay's converter to prevent large files from being ignored by Alipay.
  8. Added a debug log window to the Native mode of Window. The ShowDebugConsole=true option in the config.ini file will display the log window, which is hidden by default.
  9. Added support for modifying boolean properties in the 2D timeline animation panel.
  10. Added an option to change the layer property of all child nodes when modifying the layer property in the 3D node property panel.
  11. Added support for automatic edge adaptation based on polygon shapes in 2D physical polygon collisions.
  12. Improved the type property of the custom node in the shader blueprint.
  13. Enhanced the novice user experience: a popup will guide users to download the official Visual Studio Code website if VSCode is not installed. Added a Help menu entry for a beginner's guide (development environment and process).
