C语言小游戏源代码《贪吃蛇》

C语言程序设计：贪吃蛇程序源代码用TC2.0编译本程序为贪吃蛇游戏,想必大家都玩过这个游戏,程序源代码用TC2.0编译通过,需要图形驱动文件的支持,在TC2.0的集成环境中有.本程序利用数据结构中的链表,来将蛇身连接,同时当蛇吃到一定数目的东西时会自动升级,及移动速度会加快,程序会时刻将一些信息显示在屏幕上,包括所得分数,要吃多少东西才能升级,并且游戏者可以自己手动选择游戏级别,级别越高,蛇的移动速度越快.另外,此游戏可能与CPU的速度有关系.源代码如下:******************************************************************************* ***/*******************************COMMENTS**********************************/ /* snake_game.c*//* it is a game for entermainment.*//* in the begin,there is only a snake head,and it will have to eat food *//* to become stronger,and it eat a piece of food each time,it will *//* lengthen it's body,with the number of food the snake eats going up,it *//* will become long more and more,and the score will goes up also. *//* there is always useful information during the game process. *//* if the path by which the snake goes to eat food is the shortest,the *//* score will add up a double.*//**//* enjoy yourself,and any problem,contact <blldw@> *//*************************************************************************//* all head file that will be used */#include<stdio.h>#include<time.h>#include<graphics.h>#include<stdlib.h>#include<ctype.h>#include<string.h>/* useful MACRO */#define FOOD_SIZE 8#define SCALE 8#define UP_KEY 0x4800#define DOWN_KEY 0x5000#define LEFT_KEY 0x4b00#define RIGHT_KEY 0x4d00#define MOVE_UP 1#define MOVE_LEFT 2#define MOVE_DOWN 3#define MOVE_RIGHT 4#define INV ALID_DIRECTION 0#define QUIT_KEYC 0x1051#define QUIT_KEY 0x1071#define SELECT_KEYC 0x1f53#define SELECT_KEY 0x1f73#define PAUSE_KEYC 0x1950#define PAUSE_KEY 0x1970#define DEFAULT_LEVEL 1#define HELP_COLOR WHITE#define WELCOME_COLOR WHITE#define DEFAULT_COLOR GREEN/* define the macro as follows to improve the game in future */#define FOOD_COLOR YELLOW#define SNAKE_HEAD_COLOR RED#define DEFAULT_SNAKE_COLOR YELLOW#define EXIT_COLOR WHITE#define SCORE_COLOR YELLOW/* sturcture for snake body mainly ,and food also */typedef struct food_infor *FOOD_INFOR_PTR;typedef struct food_infor{int posx;

《贪吃蛇》游戏程序代码1. 游戏初始化：设置游戏窗口、蛇的初始位置和长度、食物的初始位置等。

2. 蛇的移动：根据用户输入的方向键，更新蛇的位置。

确保蛇的移动不会超出游戏窗口的边界。

3. 食物的：在游戏窗口中随机食物的位置。

确保食物不会出现在蛇的身体上。

4. 碰撞检测：检测蛇头是否撞到食物或自己的身体。

如果撞到食物，蛇的长度增加；如果撞到自己的身体，游戏结束。

5. 游戏循环：不断更新游戏画面，直到游戏结束。

6. 游戏结束：显示游戏结束的提示，并询问用户是否重新开始游戏。
