C语言实现贪吃蛇小游戏无需graphich头文件.docx

这个程序是参考了一部分资料以后，然后自己修改了一下，附加了一些注释，实现了贪吃蛇的基本功能。共包含snake.h和snake.c两个文件，亲测可用，下面附图一张。有共同兴趣爱好的可以进我的博客一起学习，讨论，/fisherwan/article/details/19674145snacke.h#ifndef _SNAKE_H_H_H#define _SNAKE_H_H_H/调节游戏界面大小，这里设置为15*15int const COL = 15;int const ROW = 15;/蛇节点typedef struct Nodeint x;int y;struct Node *pre;struct Node *next;NODE, *pNODE;/食物typedef struct Foodint x;int y;char c;FOOD, *pFOOD;/初始化，创建蛇的第一节pNODE InitSnake(void);/初始化食物成员FOOD InitFood(void);/蛇运动函数int MoveSnake(pNODE pHead, char c);/检查键盘按键char KbHit(char orient);/蛇吃到食物处理函数pNODE SnakeEatFood(pNODE pHead, pFOOD pFood);/打印游戏界面函数void Print(pNODE pHead, FOOD food);#endifSnake.c#include #include #include #include #include #include snake.h/主函数int main(void)char orien = a, get_char;int game_over = 0;FOOD food = InitFood();pNODE head = InitSnake();while (1)head = SnakeEatFood(head, &food);get_char = KbHit(orien);if (27 = get_char)game_over = 1;break;elseorien = get_char;game_over = MoveSnake(head, orien);if (game_over)break;system(cls);Print(head, food);Sleep(200); /ms级，刷屏间隔时间if (game_over)printf(游戏结束！n);getch();return 0;/初始化，创建蛇的第一节pNODE InitSnake(void)pNODE pHead = (pNODE)malloc(sizeof(NODE);srand(unsigned)(time(NULL)+1);if (NULL = pHead)printf(内存分配失败！n);exit(-1);pHead-x = rand() % ROW;pHead-y = rand() % COL;pHead-next = NULL;pHead-pre = NULL;return pHead;/初始化食物成员FOOD InitFood(void)FOOD food;srand(unsigned)time(NULL);food.x = rand() % ROW;food.y = rand() % COL;food.c = 65 + rand()%26;return food;/蛇吃到食物处理函数pNODE SnakeEatFood(pNODE pHead, pFOOD pFood)pNODE p_add = NULL, pt = NULL, rear = NULL;if (pFood-x = pHead-x & pFood-y = pHead-y)p_add = (pNODE)malloc(sizeof(NODE);if (NULL = p_add)printf(内存分配失败！n);exit(-1);pt = pHead;while (pt-next != NULL)pt = pt-next;p_add-pre = pt;p_add-next = NULL;pt-next = p_add;*pFood = InitFood();/不让食物出现在蛇的位置上pt = pHead;while (pt != NULL)if (pFood-x = pHead-x & pFood-y = pHead-y)*pFood = InitFood();break;pt = pt-next;return pHead;/检查键盘按键char KbHit(char orient)char c;if (kbhit()c = getch();if (orient != d & c = a)orient = c;else if (orient != a & c = d)orient = c;else if (orient != w & c = s)orient = c;else if (orient != s & c = w)orient = c;else if (27 = c)orient = c;return orient;/蛇运动函数int MoveSnake(pNODE pHead, char c)INT game_over = 0;pNODE pt = pHead;/让pt指向蛇尾while (pt-next != NULL)pt = pt-next;/从蛇尾向向蛇头前进while(pt != pHead)pt-x = pt-pre-x;pt-y = pt-pre-y;pt = pt-pre;if (d = c)pHead-x += 1;if (pHead-x = ROW)pHead-x -= ROW;if (a = c)pHead-x -= 1;if (pHead-x x += ROW;if (s = c)pHead-y += 1;if (pHead-y = COL)pHead-y -= COL;if (w = c)pHead-y -= 1;if (pHead-y y += COL;/当蛇头碰到蛇身，游戏结束pt = pHead-next;while (pt != NULL)if (pt-x = pHead-x & pt-y = pHead-y)game_over = 1;pt = pt-next;return game_over;/打印游戏界面函数void Print(pNODE pHead, FOOD food)int row = 0, col = 0, flag = 0;pNODE pt = NULL;printf( 方向控制上:w 下:s 左:a 右:d(Esc退出)n );for (row=0; rowROW; row+)printf();putchar(n);for (col=0; colCOL; col+)printf( |);for (row=0; rowx & col = pt-y)if (pt = pHead)printf();elseprintf();flag = 1;break;pt = pt-next;/打印出食物或两个空格if (0 = flag
