entities文件夹下的avatar:

proxy = lua_class( 'proxy' )
local chat_layer        = import('ui.chat_layer')
function proxy:_init()
end
function proxy:chat_msg(msg)
	chat_layer.chat_layer:chat_msg(msg)

服务端：

entities文件夹下的avatar.lua:

avatar = lua_class('avatar')
function avatar:_init(pid)
	self.pid = pid
end
function avatar:say(msg)
	for i, e in pairs(entities) do
		e.client.chat_msg(msg)
