代码框架

坦克大战游戏代码框架如下

在 main.c 中,创建应用窗口,并初始化一些系统资源,然后初始化gdi,初始化坦克大战游戏.
在 gdi.c 中,对系统的HDC及绘图接口进行了一次封装,使用WIN32系统提供的绘图接口来实现我们自己的图形绘制API.这里使用到了双缓冲技术,下文会简单介绍.
在 Tank.c 中,实现了坦克大战的游戏逻辑,包括贴图系统,地图系统,坦克制造,炮弹制造,装备生成,坦克移动,炮弹移动,以及坦克被炮弹击中,坦克吃到装备,等等.
下面将对代码进行详细的分析.

代码主函数

在 main.c 中,创建应用窗口,并初始化一些系统资源,然后初始化gdi,初始化坦克大战游戏.

//主函数
int APIENTRY wWinMain(_In_ HINSTANCE hInstance,_In_opt_ HINSTANCE hPrevInstance,_In_ LPWSTR    lpCmdLine,_In_ int       nCmdShow)
{//注册窗口类,创建窗口,初始化等: MyRegisterClass(hInstance);InitInstance(hInstance, nCmdShow);//显示初始化及游戏初始化gdi_init(hWnd);tank_init();//创建坦克大战运行线程hTankRunT = CreateThread(NULL, 0, TankRun, NULL, 0, &dwTankRunTId);//快捷键hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_GAMETANK));// 主消息循环: while (GetMessage(&msg, NULL, 0, 0)){if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)){//TranslateMessage(&msg);DispatchMessage(&msg);}}return (int)msg.wParam;
}//目的: 注册窗口类。
ATOM MyRegisterClass(HINSTANCE hInstance)
{WNDCLASSEXW wcex;......wcex.lpfnWndProc = WndProc;//绑定窗口消息处理函数......return RegisterClassEx(&wcex);//注册窗口类
}//目的: 保存实例句柄并创建主窗口
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{hInst = hInstance; // 将实例句柄存储在全局变量中......hWnd = CreateWindow(......);//无窗口创建数据ShowWindow(hWnd, nCmdShow);UpdateWindow(hWnd);return TRUE;
}//目的:    处理主窗口的消息。
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{......switch (message){case WM_COMMAND:{// 分析菜单选择: switch (wmId){case IDM_ABOUT: //关于GAME_CTRL.run = FALSE;//点击对话框的时候暂停DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);break;case IDM_README: //说明GAME_CTRL.run = FALSE;//点击对话框的时候暂停DialogBox(hInst, MAKEINTRESOURCE(IDD_READMEBOX), hWnd, Readme);break;case IDM_EXIT://退出DestroyWindow(hWnd);break;......default:return DefWindowProc(hWnd, message, wParam, lParam);}}break;case WM_PAINT:{hdc = BeginPaint(hWnd, &ps);// TODO: 在此处添加使用 hdc 的任何绘图代码...gdi_update();EndPaint(hWnd, &ps);}break;case WM_DESTROY:gdi_dinit();PostQuitMessage(0);break;case WM_KEYDOWN:switch (wParam){case VK_UP://上GAME_CTRL.dir = DIR_UP;break;case VK_DOWN://下GAME_CTRL.dir = DIR_DOWN;break;case VK_LEFT://左GAME_CTRL.dir = DIR_LEFT;break;case VK_RIGHT://右GAME_CTRL.dir = DIR_RIGHT;break;case VK_RETURN://回车键开火GAME_CTRL.fire = TRUE;break;......default:break;}break;default:return DefWindowProc(hWnd, message, wParam, lParam);}return 0;

}

GDI绘图

在 gdi.c 中,对系统的HDC及绘图接口进行了一次封装,使用WIN32系统提供的绘图接口来实现我们自己的图形绘制API.这里使用到了双缓冲技术.

双缓冲技术

坦克大战的每一次运行,坦克和炮弹的每一次移动,我们都要不断的清除屏幕上原来的内容,然后重新绘制新的内容,假如我们每一次更改显示内容都直接调用WIN32的api实时的刷新到屏幕上,一旦游戏运行速度很快的时候,就会造成屏幕上的内容一直在闪烁,非常影响游戏体验.
双缓冲技术主要是为了解决坦克大战实时刷新造成的屏幕闪烁问题.其原理就是,加入地图上共有10辆坦在战斗,每辆坦克都在移动,每移动一步我们都需要重新计算并显示10辆坦克的位置,但是我们不必在计算每一辆坦克的时候都把他刷新到屏幕上,而是先把这辆坦克绘制到内存上,等到所有的坦克都计算并完成移动之后,再同一把内存上的内容刷新到屏幕上,这样做就大大减少了刷新屏幕的次数,也就可以避免实时刷新造成的屏幕闪烁问题.
更详细的介绍,请参考下面这篇文章:

坦克大战

坦克系统

如上图所示,每个坦克由6个小方块组成,把这6个小方块按顺序标号.每个坦克有上下左右四个方向.为了简化程序操作,把这四个方向的坦克放在一个(二维)数组 TANK_SHAPE_BOX 中,即TANK_SHAPE_BOX[4][6],4表示共有四种形状的坦克(四个方向),6表示每种坦克由6个小方块. 数组的每个元素保存的是这6个小方块的相对坐标.坦克的每个方块的实际坐标可以通过坦克左上角的坐标与这6个相对坐标计算得到.
