在这里，我们主要使用C语言和数据结构链表来实现对贪吃蛇小游戏的实现。

主函数

在主函数中，我们需要实现对贪吃蛇游戏的整体流程的实现。

HideCursor();//隐藏光标显示，调用一次 srand((unsigned)time(NULL)); Snake snake; //创建游戏框架 GameStart(&snake); //游戏开始 GameRun(&snake); //游戏过程 GameEnd(&snake); //游戏结束 123456

游戏信息定义

#define INIT_X 26 //初始位列 #define INIT_Y 12 //初始位行 enum Direction //蛇的运动方向 {UP, //上DOWN, //下LEFT, //左RIGHT //右 }; enum Gamestatus //游戏状态 {OK, //正常状态NORMAL_END, //正常退出KILL_BY_WALL, //撞墙死亡KILL_EY_SELF //撞蛇死亡 }; typedef struct SnakeNode //结点位置 {int x;int y;struct SnakeNode* next; }SnakeNode, *pSnakeNode; typedef struct Snake //游戏框架 {pSnakeNode _pSnake; //蛇头指针pSnakeNode _pFood; //食物位置指针int _TotalScore; //得分int _AddScore; //增加的分数int _SleepTime; //休眠时间enum Direction _Dir;//方向enum Gamestatus _status;//游戏状态 }Snake, *pSnake;

游戏信息设置

游戏界面设置

实现对游戏界面的初始化

void WecomeToGame()//打印欢迎界面 {//设置窗口大小system("mode con cols=100 lines=30");//设置DOS窗口的尺寸将会变为100列30行的/*键入mode con cols = 100 lines = 30则DOS窗口的尺寸将会变为30行100列的，cols(列)最小值为13，lines(行)最小值为1。在C语言中也可以通过system函数调用这个dos命令来实现这个功能。*///打印文字SerPos(37, 12); //定位光标列，行printf("欢迎来到贪吃蛇小游戏");SerPos(37, 20);system("pause");system("cls");SerPos(37, 12); //定位光标列，行printf("提示：↑ ↓ ← → 控制贪吃蛇方向");SerPos(37, 13); //定位光标列，行printf("提示：F1：加速，F2，减速加速可获得更高的分数");SerPos(37, 20);system("pause");system("cls"); }

123456789101112131415161718192021222324 创建地图

通过一些特殊字符，来实现对地图边界的划分.

void CreateMap()//创建地图 60列 * 28行 {int i = 0;//上边界for (i = 0; i < 60; i = i + 2){SerPos(i, 0); //定位光标列，行printf("%s", "▇");}//下边界for (i = 0; i < 60; i = i + 2){SerPos(i, 27); //定位光标列，行printf("%s", "▇");}//左边界for (i = 1; i < 27; i++){SerPos(0, i); //定位光标列，行printf("%s", "▇");}//右边界for (i = 1; i < 27; i++){SerPos(58, i); //定位光标列，行printf("%s", "▇");} }

12345678910111213141516171819202122232425262728 打印信息

void PrintInformation(pSnake ps)//打印信息 {//打印得分SerPos(70, 10);printf("得分：%d ", ps->_TotalScore);SerPos(70, 11);printf("当前所加得分：%d ", ps->_AddScore);//打印文字SerPos(70, 12);printf("↑ ↓ ← → 控制贪吃蛇方向");SerPos(70, 13);printf("提示：");SerPos(70, 14);printf("F1：加速，F2：减速");SerPos(70, 15);printf("空格：暂停");SerPos(70, 16);printf("Esc：退出"); }
