C++中怎么执行LUA 的整篇代码不是一个函数
local function createLayer()
local layer = CCLayer:create();
local sprite = CCSprite:create("bg.png");
sprite:setPosition(200, 200);
return layer;
end
local scene = CCScene:create();
scene:addChild(createLayer());
CCDirector:sharedDirector():replaceScene(scene);

strcat_s( szScriptFilePath, MAX_PATH, pScriptFile );
g_pLua = luaL_newstate();
if( g_pLua == NULL )
__leave;
if( ! RegisterLuaAPI())
__leave;
if( luaL_loadfile( g_pLua, szScriptFilePath ) != 0 )

if( MessageBox( NULL, "配置文件中存在语法错误，无法加载，要查看详细信息吗？", "错了", MB_YESNO ) == IDYES )
