win32，main入口

int APIENTRY _tWinMain(HINSTANCE hInstance,                       HINSTANCE hPrevInstance,                       LPTSTR    lpCmdLine,                       int       nCmdShow){    UNREFERENCED_PARAMETER(hPrevInstance);    UNREFERENCED_PARAMETER(lpCmdLine);    // create the application instance    AppDelegate app;    return Application::getInstance()->run();}

  UNREFERENCED_PARAMETER：作用，不必显示警告

  AppDelegate app; //AppDelegate继承private Application继承public ApplicationProtocol
ApplicationProtocol是一个抽象类，定义了Platform平台一些程序运行状态的函数，applicationDidFinishLaunching，applicationDidEnterBackground，applicationWillEnterForeground
帧数，当前语言，当前平台
CCApplication:抽象类(没有实现父类所有接口函数)，单列模式
 Application::getInstance()->run();
//...
if(!applicationDidFinishLaunching())->在AppDelegate中实现
{
return 0;
}
//...
//主循环
  while(!glview->windowShouldClose())    {        QueryPerformanceCounter(&nNow);        if (nNow.QuadPart - nLast.QuadPart > _animationInterval.QuadPart)        {            nLast.QuadPart = nNow.QuadPart;                        director->mainLoop();            glview->pollEvents();        }        else        {            Sleep(0);        }    }
AppDelegate中实现
bool AppDelegate::applicationDidFinishLaunching() {    // initialize director    auto director = Director::getInstance();    auto glview = director->getOpenGLView();    if(!glview) {        glview = GLView::create("My Game");//        director->setOpenGLView(glview);    }    // turn on display FPS    director->setDisplayStats(true);    // set FPS. the default value is 1.0/60 if you don't call this    director->setAnimationInterval(1.0 / 60);    // create a scene. it's an autorelease object    auto scene = HelloWorld::createScene();    // run    director->runWithScene(scene);    return true;}

//todo java

cocos2d-x 程序的结束流程

在弹出最后一个场景，直接调用CCDirector::end()；触发游戏清理工作purgeDirector
