概述在main.lua中。必须要的代码 cc.FileUtils:getInstance():addSearchPath("src")cc.FileUtils:getInstance():addSearchPath("res")-- CC_USE_DEPRECATED_API = truerequire "cocos.init"-- cclogcclog = function(...)

在main.lua中。必须要的代码

	 --   local gameScene = require("GameScene") --   local scene = gameScene.create()	--scene:playBgMusic()	    local scene = GameScene:create()	scene:playBgMusic()	if cc.Director:getInstance():getRunningScene() then		cc.Director:getInstance():replaceScene(scene)	else		cc.Director:getInstance():runWithScene(scene)	endendlocal status,msg = xpcall(main,__G__TRACKBACK__)if not status then	error(msg)end

然后定义另外一个GameScene.lua文件
