HTML5 2D 游戲引擎：Coffee2D

Coffee2D 是一個 HTML5 游戲引擎，它將開發 HTML5 Canvas 游戲中大量的工作抽象出來，例如 CoffeeScript 特性（如 class 關鍵字）來更好的與游戲和 CoffeeScript 集成。

Coffee2D 當前提供：

• 簡單場景圖

• 精靈渲染

• 事件處理

• 動畫

• Isometric 地圖

組件：

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()

事件處理：

# 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'}
