Drag and drop

drag_drop.coffee

define [
  'caper/actor'
], (Actor) ->

  class Ball extends Actor
    added: ->

      #DRAGGABLE
      @dragImage = @bitmap 'draggy'
      @stage.addChild @dragImage
      
      @draggable = @makeDraggable(@dragImage)
   
      @draggable.on 'dropped', (draggable, droppable) =>
        @emit 'dropped', draggable, droppable

      #DROPPABLE
      @dropImage = @bitmap 'dropzone'
      @stage.addChild @dropImage
      @droppable = @makeDroppable(@dropImage)
      @droppable.on 'dropped', (droppable, draggable) =>
        console.log 'droppable detected a drop'

FYI you're missing the droppable class in the define
