C语言编写的俄罗斯方块

用C语言写的一个简单的俄罗斯方块！会用到graphics.h的库，需要自己准备，可以在网上下载EasyX 解决。

下边是源代码（扩展名为.cpp）：#include <easyx.h>#include <conio.h>#include <time.h>#define WIDTH 10 // 游戏区宽度#define HEIGHT 22 // 游戏区高度#define UNIT 20 // 每个游戏区单位的实际像素// 定义操作类型enum CMD{CMD_ROTATE, // 方块旋转CMD_LEFT, CMD_RIGHT, CMD_DOWN, // 方块左、右、下移动CMD_SINK, // 方块沉底CMD_QUIT // 退出游戏};// 定义绘制方块的方法enum DRAW{SHOW, // 显示方块CLEAR, // 擦除方块FIX // 固定方块};// 定义七种俄罗斯方块struct BLOCK{WORD dir[4]; // 方块的四个旋转状态COLORREF color; // 方块的颜色} g_Blocks[7] = { {0x0F00, 0x4444, 0x0F00, 0x4444, RED}, // I{0x0660, 0x0660, 0x0660, 0x0660, BLUE}, // 口{0x4460, 0x02E0, 0x0622, 0x0740, MAGENTA}, // L{0x2260, 0x0E20, 0x0644, 0x0470, YELLOW}, // 反L{0x0C60, 0x2640, 0x0C60, 0x2640, CYAN}, // Z{0x0360, 0x4620, 0x0360, 0x4620, GREEN}, // 反Z{0x4E00, 0x4C40, 0x0E40, 0x4640, BROWN}}; // T// 定义当前方块、下一个方块的信息struct BLOCKINFO{byte id; // 方块 IDchar x, y; // 方块在游戏区中的坐标byte dir:2; // 方向} g_CurBlock, g_NextBlock;// 定义游戏区BYTE g_World[WIDTH][HEIGHT] = {0};void Init(); // 初始化游戏void Quit(); // 退出游戏void NewGame(); //开始新游戏void GameOver(); //结束游戏CMD GetCmd(); //获取控制命令void DispatchCmd(CMD _cmd);// 分发控制命令void NewBlock(); //生成新的方块bool CheckBlock(BLOCKINFO _block);// 检测指定方块是否可以放下void DrawUnit(int x, int y, COLORREF c, DRAW _draw); // 画单元方块void DrawBlock(BLOCKINFO _block, DRAW _draw = SHOW); // 画方块void OnRotate(); //旋转方块void OnLeft(); //左移方块void OnRight(); //右移方块void OnDown(); //下移方块void OnSink(); //沉底方块// 主函数void main(){Init();//界面函数CMD c;while(true){c = GetCmd();DispatchCmd(c);// 按退出时，显示对话框咨询用户是否退出if (c == CMD_QUIT){HWND wnd = GetHWnd();if (MessageBox(wnd, _T("您要退出游戏吗？"), _T("提醒"), MB_OKCANCEL | MB_ICONQUESTION)== IDOK)Quit();}}}//界面void Init(){initgraph(640, 480); //初始化文本框宽度、高度srand((unsigned)time(NULL)); //产生随机数setbkmode(TRANSPARENT); // 设置图案填充的背景色为透明// 显示操作说明settextstyle(14, 0, _T("宋体"));outtextxy(20, 330, _T("操作说明"));outtextxy(20, 350, _T("上：旋转"));outtextxy(20, 370, _T("左：左移"));outtextxy(20, 390, _T("右：右移"));outtextxy(20, 410, _T("下：下移"));outtextxy(20, 430, _T("空格：沉底"));outtextxy(20, 450, _T("ESC：退出"));// 设置坐标原点setorigin(220, 20);// 绘制游戏区边界rectangle(-1, -1, WIDTH * UNIT, HEIGHT * UNIT);rectangle((WIDTH + 1) * UNIT - 1, -1, (WIDTH + 5) * UNIT, 4 * UNIT);// 开始新游戏NewGame();}// 退出游戏void Quit(){closegraph();exit(0);}// 开始新游戏void NewGame(){// 清空游戏区setfillcolor(BLACK);//游戏区背景颜色solidrectangle(0, 0, WIDTH * UNIT - 1, HEIGHT * UNIT - 1);ZeroMemory(g_World, WIDTH * HEIGHT);// 生成下一个方块g_NextBlock.id = rand() % 7;g_NextBlock.dir = rand() % 4;g_NextBlock.x = WIDTH + 1;g_NextBlock.y = HEIGHT - 1;// 获取新方块NewBlock();}// 结束游戏void GameOver(){HWND wnd = GetHWnd();if (MessageBox(wnd, _T("游戏结束。
