Event design - client listens directly to object

gistfile1.coffee

class enemy extends EventEmitter

load: ->
  emit 'load'

move: (location) ->
  # moves an enemy across the game
  emit 'move', location

class world extends EventEmitter

enemy.on 'load'
  # process loading
  emit 'loaded', enemy
  enemy.move [3, 2]
  

class client extends EventEmitter

world.on 'loaded', object
  # load object data
  object.on 'move'
    # show enemy moving to the client
