1、C+源代码游戏编程-WinMain()函数集 C+源代码游戏编程-WinMain()函数交流/*/函数：WinMain()/功能：应用程序入口/*int PASCAL WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow) MSG msg; hInst=hInstance; /初始化主窗口 if (!InitWindow( hInstance, nCmdShow) return FALSE; /初始化DirectDraw环境 if (!InitDDraw() MessageBox(

2、hWndMain, 初始化DirectDraw过程中出错！, Error, MB_OK); FreeObjects(); DestroyWindow(hWndMain); return FALSE; /进入消息循环 while(1) if(PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE) if(!GetMessage(&msg, NULL, 0, 0 ) return msg.wParam; TranslateMessage(&msg); DispatchMessage(&msg); else if(bActive) UpdateFrame(); else

3、WaitMessage(); return msg.wParam;/-/ Name: WinMain()/ Desc: Initialization, message loop/-int PASCALWinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow) MSG msg; if (InitApp(hInstance, nCmdShow) != DD_OK) return FALSE; while (GetMessage(&msg, NULL, 0, 0) TranslateMessage

4、(&msg); DispatchMessage(&msg); return msg.wParam;/ 主循环/int PASCAL WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nCmdShow) MSG msg; if(!InitApp(hInst, nCmdShow) return FALSE; while(1) if(PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE) if(!GetMessage(&msg, NULL, 0, 0 ) return msg.wPara

5、m; TranslateMessage(&msg); DispatchMessage(&msg); else if(bActive) Update(); / 翻转上一层缓冲区内容到屏幕。 Screen-Flip(); else WaitMessage(); /int PASCAL WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow) / any windows programmer should be familiar with this MSG msg; lpCmdLine =

7、 row and then flip while(1) ddrval = lpDDSPrimary-Flip(NULL, DDFLIP_WAIT); if(ddrval = DD_OK) break; if(ddrval = DDERR_SURFACELOST) if(ddrval != DD_OK) break; if(ddrval != DDERR_WASSTILLDRAWING) break; / if bActive else /make sure we go to sleep if have nothiing to do WaitMessage(); / win main/-/ Na

8、me: WinMain()/ Desc: 入口,初始化，进行消息循环/-int PASCALWinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow) MSG msg; if (InitApp(hInstance, nCmdShow) != DD_OK) return FALSE; Map0.Width=width; Map0.Hight=height; Map0.Data=(char *)malloc( Map0.Width * Map0.Hight ); Map0.Pro=(char *
