v0.7.0

Audio System

A complete cross-platform audio module with ECS components, bus-based mixing, and spatial audio support.

AudioSource component — attach to any entity to play sound effects or music, with properties for volume, pitch, loop, bus routing (sfx, music, ui, voice), and playOnAwake
AudioListener component — add to the camera or player entity to enable spatial audio with configurable attenuation models (Linear, Inverse, Exponential)
Static Audio API — Audio.playSFX(), Audio.playBGM(), Audio.stopBGM() for quick one-shot playback; per-bus volume control via Audio.setMasterVolume(), Audio.setMusicVolume(), etc.
Editor integration — audio file inspector with inline preview player, drag-to-scene support, and a mute toggle button in Game View
Cross-platform — uses Web Audio API with automatic AudioContext resume handling; playOnAwake defers until the context is running

A frame-based sprite animation system with a visual clip editor in the editor.

SpriteAnimator component — plays registered animation clips with configurable speed, loop, and play state
.esanim asset format — define animation clips with a list of texture frames and FPS
Clip registry — registerAnimClip() / getAnimClip() API for managing animation clips at runtime
Editor visual editor — create and edit .esanim clips directly in the editor with frame preview

Real-time performance monitoring with an overlay panel and frame inspection.

StatsPlugin — add to your app to enable performance collection with an optional on-screen overlay
Metrics — FPS, frame time, draw calls, triangle count, sprite/text/spine/mesh counts, culled entities, total entity count
System timings — shows the top 5 slowest systems per frame with execution time in milliseconds
Frame history — 300-frame rolling buffer for trend analysis; supports pause/resume and per-frame inspection
Editor integration — profiler panel accessible from the editor toolbar

JS-side value tweening for animating custom properties beyond the built-in targets.

Tween.value() API — tween any numeric value with a callback, using the same easing, delay, loop, and sequencing features as Tween.to()
16 easing functions — all easing functions ported 1:1 from C++ to JS, including CubicBezier and EaseOutBounce
Cross-type chaining — chain Tween.to() and Tween.value() via .then() in any order
applyEasing() utility — public function to evaluate any easing curve for custom use

Asset build transforms — registerAssetBuildTransform() API on AssetTypeEntry replaces per-type branching in emitters. Both platform emitters now use generic entry.buildTransform() calls. Users can register custom transforms for their own asset types.
Tree-shaking — enable tree-shaking and consolidate runtime initialization logic for smaller bundles
AssetTypeRegistry — centralized asset type metadata, replacing scattered per-module registration
Audio platform abstraction — audio backend creation moved into the platform adapter layer
WASM optimizations — enable bulk-memory and nontrapping-float-to-int in wasm-opt for better performance

Fix gizmo drag Transform value fighting — use direct Transform sync instead of deferred updates
Fix circular dependencies between AssetTypeRegistry and FileInspector / InspectorHelpers
Preload audio assets in editor scene manager
Skip AudioPlugin system registration in editor Scene View (audio only runs in Game View)
Stop all audio when exiting editor play mode

Defer playOnAwake until AudioContext is running to avoid silent playback on first load
Add audio MIME type detection and auto-repair for unknown asset meta files
Fix WeChat audio not playing — set properties before src, use explicit play() instead of autoplay, add onError callback

Fix anim-clip textures missing in build — add build transform to rewrite atlas-packed frame paths with atlasFrame metadata

Add TDD tests for core SDK modules (world, input, resource, query) with 100% coverage
Add TDD tests for rendering pipeline (renderTexture, sceneManager)
Add TDD tests for UI modules (uiMath, uiLayout)
Add asset type tests and expand logger test coverage to 100%
