This project contains the commercially-proven HTML5 game engine based on canvas and DOM/GPU specialized for mobile devices (Android and iOS).

Even there are a number of open source HTML5 game engines out there, we're proud of our engine by differentiating it from others, which provides mobile-device optimized performance improvement techniques. One of them is to support hybrid rendering context of canvas and DOM/GPU.

By capatilizing on the hybrid rendering context, a game based on our engine can be developed to run on even Android 2.3.x and 4.4/4.4.2 (which suffer from severe performance degradation due to Chrome Webview defect).

Major Features

• require.js based modularization
• mobile device optimized performance including canvas/DOM hybrid rendering context, static object pool
• multi-resolution support for various devicePixelRatio handling
• general game engine feature including sound (WebAudio/Audio tag), Sprite Animation, etc

Roadmap (2.0)

• WebGL back-end for better performance on Android L and iOS8
• support to load mixed resolution resources
• WebWorker integration
• Physics Engine integration (Box2D, physicsJs)
• Smart repaint algorithm improvement (invalidated region merge, Board-level support)
• Entity level event binding
• V8/Jit friendly engine refactoring
• Garbage collector improvement (in an effort to suppress GC almost completely)
• Online DPI/canvas-aware optimized image generation
