v0.8.3

Tip

v0.8.3 restructures the build pipeline with templates, hooks, and config management, adds physics support for playable builds, and fixes touch input and slider behavior.

Build Pipeline Overhaul

The build system has been restructured with new features for automation and reuse:

• Build Templates — 7 built-in presets (Facebook Playable, Google Playable, Playable Debug, WeChat Production, WeChat Debug, WeChat Single File, WeChat Landscape) plus the ability to save custom templates from existing configs
• Build Hooks — pre-build and post-build hooks for copying files (with glob patterns) or running shell commands, enabling custom automation workflows
• Config Import/Export — export build configurations as JSON for backup or team sharing, and import them on another machine
• Build Status Indicators — green/red dots on each configuration showing the last build result at a glance
• Auto Plugin Detection — the build now automatically detects which UI plugins your scenes need (Text, UIRect, etc.) and includes only those, reducing output size

See the Building guide for details on templates and hooks.

Physics in Playable Builds

Playable ad builds now fully support the Box2D physics module. When physics is enabled in project settings, the physics WASM binary is automatically embedded as base64 in the single-file HTML output. A body position synchronization bug was also fixed, ensuring physics bodies correctly track their Transform positions.

Audio in Playable Builds

Audio loading in playable builds has been fixed. Audio clips referenced by AudioSource components are now correctly embedded and loaded at runtime. Previously, audio files could fail to load in the single-file HTML output.

Touch Input Improvements

• Added touchcancel event handler to the web adapter, preventing stuck touch states when the browser cancels a touch (e.g., system gesture, notification overlay)
• Touch events now call preventDefault() to avoid unintended browser behaviors (scroll, zoom) during gameplay

Slider Fix

The slider drag system now uses UIInteraction.pressed state instead of internal closure state, fixing an issue where sliders could become unresponsive after rapid interactions.

Editor Fixes

• Collision layer dropdown in the Inspector now refreshes immediately when layers are renamed or added in project settings
• Audio playback in the editor preview now works correctly (CSP media-src policy updated)

Example Projects

A new physics-spinner example project demonstrates physics-driven gameplay with dynamic body spawning, motor joints, and collision layers.
