本节简单对新生成的hellowrold 项目相关代码进行简单分析，具体以代码注释的方式展示给大家。代码相对简单些，在此不作过多赘述，直接上码：

int APIENTRY _tWinMain(HINSTANCE hInstance,                       HINSTANCE hPrevInstance,                       LPTSTR    lpCmdLine,                       int       nCmdShow){    // UNREFERENCED_PARAMETER 避免编译器关于未引用参数的警告    UNREFERENCED_PARAMETER(hPrevInstance);    UNREFERENCED_PARAMETER(lpCmdLine);        //新建一个代理实体    AppDelegate app;    CCEGLView* eglView = CCEGLView::sharedOpenGLView();    // 初始化win32下游戏窗体大小及标题等信息    eglView->setViewName(UTEXT("这是一个测试啦"));    eglView->setFrameSize(900, 600);    return CCApplication::sharedApplication()->run();}
