[QUOTE]哎。。这个游戏代码是一本书上的，但是我在实现之后与书上画出的结果完全不同。在书上，画出的是定时出现黄圈并且用线相连，但是自己的却不知道为什么失去了效果。请教大牛们。下面是全部的代码： ------------------------------------- BLIZZARD.CPP全部代码： //Blizzard应用程序 //C++文件 //包含文件如下 #include "Blizzard.h" BOOL GameInitialize(HINSTANCE hInstance) { //创建游戏引擎 g_pGame=new GameEngine(hInstance,TEXT("1a"),TEXT("11"),IDI_ICON2,IDI_ICON1);
