LayaAir 3.2.8 Engine Library

更多版本日志以及IDE的下载，请前往LayaAir官网：https://layaair.com/#/engineDownload

BUG Fixes

1. Fixed a bug where destroying a Spine object did not release video memory, causing VRAM accumulation.
2. Fixed a bug causing animation memory overflow.
3. Fixed a bug where after setting the 2D rigid body angular velocity or setting the rigid body gravity scale to 0, the rigid body would still fall and rotate.
4. Fixed a bug on Windows where button text did not scale when the window was enlarged.
5. Fixed a bug where enabling fast rendering mode in IDE preview for Spine caused an error.

New Features

1. Added: Text/Label now has a Single Character Rendering property. When enabled, characters with the same glyph and font size will share a single global cache, useful for dynamic text. This avoids memory and performance overhead caused by generating a large number of text atlases when text content is frequently updated.

New Features and Optimizations

1. Added: Refactored the statistics system. IDE now supports customizable statistics display and engine provides interfaces for custom statistics. Developers can freely choose what to display and organize.
2. Added: 2D DrawCall auto-optimization feature.
   1. The new 2D system supports dynamic batching: consecutive elements meeting certain conditions (e.g., from the same atlas, same material) are automatically merged into a single DrawCall (DC).
   2. LayaAir will adjust objects with the same material to consecutive rendering order without changing final display, allowing dynamic batching. This adjustment is transparent to developers.
   3. Enabled via node property DrawCallOptimize; all child and grandchild nodes of the node will be automatically merged. Note: when element count exceeds ~500, CPU usage may increase.
3. Added: Text/Label (classic UI)/GTextField (new UI) has a "single-character rendering" option. When enabled, identical characters of same size share one cache globally, reducing memory and performance overhead for dynamic text.
4. Added: Sprite now has zIndex property to control rendering order. Higher zIndex renders on top. By default, this order is global. When stackingRoot = true, zIndex only affects internal rendering order.
5. Added: Classic UI layout containers HBox/VBox now support autoSizeMode and skipHidden options for automatic layout.
6. Added: 3D scene viewport coordinate axis widget with quick keys for front, back, left, right, top, bottom views (Ctrl+Shift+1 to Ctrl+Shift+6).
7. Added: Timeline panel now supports selecting all keyframes vertically below the clicked frame when holding Ctrl+Shift.
8. Added: TileMap can now be dragged with middle mouse button for editing.
9. Added: TileMap editing now supports Ctrl+Z undo and Ctrl+Y redo.
10. Added: Third-party TiledMap exports now support CSV format.
11. Added: Audio resources can be dragged into the hierarchy panel to create audio nodes directly.
12. Added: Blueprint panel now supports custom shortcuts; developers can assign keys to frequently used panels.
13. Optimized: Blueprint materials now support Chinese.
14. Optimized: Animation state machine parameter panel now uses input fields for parameter names, avoiding confusion about editing.
15. Optimized: Refactored native engine audio playback.
16. Optimized: Improved list and panel component property panel display in IDE.
17. Optimized: Refactored 2D physics helper lines to no longer depend on Line2D library, avoiding errors when Line2D is not checked.
18. Optimized: Native installer now prompts network error if no connection on startup.

1. Decoupled the engine library reference relationships, solving the issue where .glsl files could not be loaded if the 3D core module was not checked in the IDE.
2. Added the mulDefine macro configuration setting in ShurikenParticleShaderDeclaration, allowing developers to choose whether to enable it, optimizing shader compilation efficiency in different scenarios.
3. By default, the texture source file option is checked when publishing on Douyin and WeChat platforms to avoid confusion for developers.
4. Upgraded the API documentation website with a brand-new interface, supporting both light and dark modes (URL: https://layaair.com/3.x/api/index.html).
5. Added a shape editing tool button for 3D physics colliders and optimized the display of component properties and descriptions for 3D physics components.
6. Removed deprecated parameters from OPPO (which caused errors).
7. Removed the restriction on the required suffix when publishing to the vivo platform (vivo platform update).
8. After publishing a vivo mini-game, command-line QR code debugging is now supported.

Version 3.2.3 Release Changelog

Bug Fixes

Engine

1. Fixed a rendering error when all slot.alpha values in a Spine animation are set to 0, and an issue with the last frame not updating correctly.
2. Fixed the incorrect playState return after a non-looping Spine animation finishes playing.
3. Fixed an issue where enabling fast rendering in Spine caused rendering to freeze on the first frame after playback in certain scenarios.
4. Fixed inconsistencies between Spine editor effects and engine rendering under specific conditions.
5. Fixed incorrect brightness when using additive blending in Spine.
6. Fixed errors in Spine under WebGPU mode when sceneData is null.
7. Fixed an issue where child node scripts continued executing after the parent node was disabled and the child node was removed.
8. Fixed an issue with HTML text formatting where overflow handling and truncation with ellipsis displayed abnormally.
9. Fixed a bug where frequent changes to button skins could cause display confusion.
10. Fixed unit conversion issues when retrieving linear velocity for 2D rigid bodies.
11. Fixed an error when enabling 2D rigid bodies.
12. Fixed an issue where canvas transparency settings were ineffective.
13. Fixed incorrect masking effects when mask nodes were rotated.
14. Fixed an issue where setting texture repeat on PBR materials with non-power-of-two textures was ineffective.
15. Fixed incorrect video texture effects in the native engine.
16. Fixed the bug where the ray function modified the input values.

IDE

1. Fixed incomplete display of a polygon set as a mask node in the scene panel of the IDE.
2. Fixed an error in the atlas creation tool when texture scaling was set to 0.8.
3. Fixed an error during undo (Ctrl+Z) after deleting a polygon point using Alt.
4. Fixed an error when converting a text node to a label node.
5. Fixed an issue where multiple settings of Constant in timeline animations could not be saved.
6. Fixed an issue where new vertices could not be added to the last edge of a polygon in the scene editor.
7. Fixed an issue where the Tree component's tree node rendering callback was triggered twice.
8. Fixed an issue where replacing images in prefabs displayed correctly in preview but not after publishing.
9. Fixed an issue where the 2D scene editing area would not display in certain scenarios.
10. Fixed a bug where the order of serialized properties for prefab root nodes differed from the definition order.
11. Fixed an error when extracting template files with a large number of compressed files, causing decompression failures on some computers.
12. Fixed an issue on macOS where the Command+Option+I shortcut remained occupied by the IDE even when it lost focus, preventing the same shortcut from being used in other applications.
13. Fixed an issue where more than 30 scenes in the build and publish settings could not be displayed.
14. Fixed a bug in the texture processing tool where scaling to a power of two was skipped.

Additions and Optimizations

1. Optimized a series of resource memory recycling issues, thanks to detailed feedback from the community developer (ID: codetypes).

2. Optimized particle compilation duration by adding the mulShaderDefineMode configuration to the ShuriKenParticle3DShaderDeclaration class. When set to true, it enables multi-macro mode, reducing single-particle compilation time but increasing macro variables and shader count. When set to false, it disables multi-macro mode, increasing single-particle compilation time but reducing macro variables and shader count.

3. Disabled setting button state color transparency in the IDE to prevent developer misuse.

4. Added the maxDeltaTime interface to Spine, allowing developers to remove playback speed limits when controlling playback speed via Laya.timer.scale.

   It is recommended to use playbackRate() to control playback speed instead of modifying Laya.timer.scale for Spine playback.
