class 关键字）来更好的与游戏和 CoffeeScript 集成。
Coffee2D 当前提供：
-
简单场景图

Isometric 地图
组件：
class Card extends Component constructor: (@suit, @value) -> super() @setSize(50, 80) # the rectangle will be drawn automatically @addChild new Rect 0, 0, @size.w, @size.h, 'white' update: (dt) -> # dt is delta time passed since last update # (update stuff...) super() draw: (ctx) -> # ctx is the canvas context associated with this scene # (draw additional stuff other than the rectangle...) super()
事件处理：
# event origin is automatically set to unit
unit.dispatchEvent {type: 'kill', target: enemy}
enemy.addListener 'kill', (evt) -> if evt.target == enemy then enemy.die()
# can also fire events from Event class, origin will not be set
Event.dispatchEvent {type: 'init'}
