最佳答案

You can define class methods by prefixing them with @:

class Box2DUtility
constructor: () ->
@drawWorld: (world, context) -> alert 'World drawn!'


# And then draw your world...
Box2DUtility.drawWorld()

And if you want your drawWorld to act like a constructor then you can say new @ like this:

class Box2DUtility
constructor: (s) -> @s = s
m: () -> alert "instance method called: #{@s}"
@drawWorld: (s) -> new @ s


Box2DUtility.drawWorld('pancakes').m()
