}逐行读下，最后一行是TestLua中调用到lua脚本了以下。我们细看一下controller.lua做了些什么。
-- avoid memory leak
collectgarbage("setpause", 100)
collectgarbage("setstepmul", 5000)
require "luaScript/mainMenu"
----------------
-- run
local scene = CCScene:create()
scene:addChild(CreateTestMenu())
CCDirector:sharedDirector():runWithScene(scene)
2.创建一个场景
3.把CreateTestMenu() 的返回值加入到场景类里。执行场景。CreateTestMenu()方法是在mainMenu.lua里的
进入mainMenu.lua里看一下
1.首先require一堆文件
2.有一个局部变量_allTests。这个table是构造出TestLua的demo的主菜单。(lua通过表来构造自己想要的结构。这是强大的地方之中的一个)
3.CreateTestMenu里做些什么事呢？
local Idx = tag - 10000
local testScene = CreateTestScene(Idx)
if testScene then --替换场景
CCDirector:sharedDirector():replaceScene(testScene)
endlocal function CreateTestScene(nIdx)
--通过下标来调用相应的函数
local scene = _allTests[nIdx].create_func()
--清空缓存
CCDirector:sharedDirector():purgeCachedData()
return scene
end
menuCallBack主要为了通过下标来找到相应要调用的函数来创建场景。
