Release Note

Engine

New Features

  • Added functionality for manually loading Wasm/AsmJS modules to improve initial scene load speed. PR.
  • node.setSiblingIndex now supports negative indices, enabling reverse indexing of child nodes. PR.
  • Added support for PipelinePass in the new rendering pipeline, allowing effects like post-processing through component additions. PR.

Optimizations

  • Package size reductions:
    • Removed unused Web platform GFX layer code and applied Terser compression to shorten internal property lengths. PR.
    • Enabled “inline enums” and “private property compression” for engine code. Internal properties marked with a ` suffix are compressed in the build process.
    • Spine module optimized, reducing size by approximately 40% compared to v3.8.4.
    • Declared ts class constructors explicitly to avoid generating unnecessary code. PR.

Bug Fixes

  • Fixed an issue where receiving WebSocket messages on Android when switching to the background or covered by other activities caused JNI crashes. PR.
  • Resolved an issue with the character controller not triggering onControllerTriggerEnter. PR.
  • Fixed raycast errors in the Bullet engine. PR.
  • Resolved raycast issues in Box2D caused by inconsistent object masks. PR.
  • Addressed memory leaks in Bullet physics. PR.
  • Fixed hot update UI freezing when handling a large number of files. PR.
  • Additional bug fixes:
    • UiOpacity issues on Web and Native platforms.
    • ScrollView frequent object creation problems.
    • Crashes on Android from repeated game entry/exit.
    • Incorrect mesh instanced attribute handling for INT type attributes.

Editor

New Features

  • Added a “View/Select” Gizmo mode to the scene view.
  • Enabled mouse wheel to adjust base roaming speed in camera roaming mode.
  • Clipping module now supports linked flags, such as manual loading of Spine.
  • Preview support for prefabs and Spine components in the property inspector.
  • Upgraded the Electron version to 31.3.1 for better performance.

Optimizations

  • Improved drag-and-drop and UI indicators in the hierarchy manager to reduce misoperations.
  • Enhanced scene view selection logic for prefabs:
    • First click selects the prefab root node.
    • Subsequent clicks prioritize the target point and gradually select upward.
  • Improved tooltip effects in the property inspector.
  • Smoothed camera zoom effects in the 3D scene view.
  • Optimized script-heavy projects to reduce wait times after modifications.

Bug Fixes

  • Fixed an issue where auto-atlas compression left unused original textures.
  • Resolved problems with frame selection of 2D nodes in the 2D view.
  • Addressed prefab-related issues in the editor, including nested prefab modifications causing node loss.
  • Fixed property inspector issues with nested array deletion affecting outer layers.
  • Improved project build prompts for scripts, engines, and native simulators.

That looks pretty good, team!
One question from my side is regarding the Google Play support. Could you kindly expand on that topic and what features you would be supporting?

4

Sure, it includes:

  • a build target for google play
  • better large screen & foldable support
  • google play API support

Thanks so much for the answer! Looking forward for this update.

  • google play API support → Such support will be possible to be done without the need to tweak the native project?
6

is it possible to add custom editor themes? I saw somewhere in between lines, editor already reads a “theme” file. If you could add a feature to read custom theme files, users can customize the looks of editor.

7

Good idea, but I must say sorry, this feature isn’t supported at the moment.

8

Sorry, what is said google play api is something like paying API. You can invoke pay API in typescript.

I’ve just experienced a potential bug of 3.8.5
Executing these 2 simple lines of code

    const testVec3 = v3(0.0058, 0.011, 0.001);
    console.log(`testVec3 = ${testVec3} // toString=${testVec3.toString()} // JSON.stringify=${JSON.stringify(testVec3)} // x,y,z = ${testVec3.x}, ${testVec3.y} / ${testVec3.z}`);

I got this result

testVec3 = (0.01, 0.01, 0.00) // toString=(0.01, 0.01, 0.00) // JSON.stringify={"x":0.0058,"y":0.011,"z":0.001} // x,y,z = 0.0058, 0.011 / 0.001

It made me confused a while & thought my code has bug but finally found that logging a vec3 out to console had a problem. Did I misunderstand Vec3 or is it a bug?

I think it’s a bug of toString method in vec2/3/4.ts .
They override the toString method and invoke toFixed for each element.

public toString (): string {
    return `(${this.x.toFixed(2)}, ${this.y.toFixed(2)}, ${this.z.toFixed(2)})`;
}

I will try to fix the issue in v3.8.6.
