C语言课程设计贪吃蛇源代码

1、C语言程序贪吃蛇代码#include#include#include#include#include#define N 21FILE *fp;int S;void boundary(void);/开始界面void end(void); /结束void gotoxy(int x,int y)/位 置函数COORD pos;pos.X=x;pos.Y=y;SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos); void color(int a)颜色函数SetConsoleTextAttribute(GetStdHandle(ST

2、D_OUTPUT_HANDLE),a); void init(int food2)初始化函数(初始化围墙、显示信息、苹果) system(cls);int i,j;/初始化围墙int wallN+2N+2=0;初始化围墙的二维数组for(i=1;i=N;i+)for(j=1;j=N;j+)wallij=1;color(10);for(i=0;iN+2;i+) 畵围墙for(j=0;jN+2;j+)if(wallij)printf( );else printf(#) ;printf(n) ;gotoxy(N+3,3);显示信息color(14);printf(tt 按 a,b,c,d 改变方向n

3、);gotoxy(N+3,1);color(14);printf(tt按任意键暂停，按1返回，按2退出n);gotoxy(N+5,3);color(14);printf(score:n);food0=rand()%N+1; 随机出现食物food1=rand()%N+1;gotoxy(food0,food1);color(12);printf(*n);void play()具体玩的过程system(cls);int i,j;int* snake=NULL;定义蛇的二维指针int food2;食物的数组，food0代表横坐标，food1代表纵坐标int score=0;为得分int tail2;此

4、数组为了记录蛇的头的坐标int node=3;蛇的节数char ch=p;srand(unsigned)time(NULL);随机数发生器的初始化函数init(food);snake=(int*)realloc(snake,sizeof(int*)*node);/改变 snake 所指内存区域的大小为 node 长度for(i=0;inode;i+)snakei=(int*)malloc(sizeof(int)*2);for(i=0;i0;i-)/蛇想前移动的关键算法，后一节的占据前 节的地址坐标snakei0=snakei-10;snakei1=snakei-11;gotoxy(snakei

5、0,snakei1);color(14);printf(*n);if(kbhit()捕捉输入信息ch=getche();switch(ch)case w:snake01-;break;case s:snake01+;break;case a:snake00-;break;case d:snake00+;break;case 1:boundary() ;break;case 2:end();break;default: break;gotoxy(snake00,snake01);color(14);printf(*n);Sleep(abs(200-0.5*score);/使随着分数的增长蛇的移动

6、速度越来越快if(snake00=food0&snake0l=foodl)/R吃 掉食物后蛇分数加 1,蛇长加 1 score+;分数增加S=score;node+;/节数增加snake=(int*)realloc(snake,sizeof(int*)*node);snakenode-l=(int*)malloc(sizeof(int)*2);food0=rand()%N+1;产生随机数且要在围墙内部food1=rand()%N+1;gotoxy(food0,food1);color(12);printf(*n);gotoxy(N+12,3);color(14);printf(%dn,scor

7、e);输出得分if(snake01=0|snake01=N+1|snake00=0|snake00=N+1)/撞到围墙 后失败gotoxy(N/2,N/2);color(30);printf(GAME OVERn);for(i=0;inode;i+)free(snakei);Sleep(INFINITE);exit(0);/从蛇的第四节开始判断是否撞到自己，因为蛇头为两节，第三节不可能拐过来for (i=3; inode; i+)for(j=0;jnode;j+)if (snakei0=snakej0 & snakei1=snakej1) gotoxy(N/2,N/2);color(30);p

8、rintf(GAME OVERn); for(i=0;inode;i+) free(snakei);Sleep(INFINITE); exit(0);void end()结束函数system(cls);system(cls);printf(EXITn);void grade()成绩记录函数system(cls);int i=0;char s;if( (fp=fopen(f:贪吃蛇 贪吃蛇.txt,ar) )=NULL)打开文件 printf(nCannot open file!n);exit(0);if(iS)i=S;color(14);fwrite(&i,sizeof(i),1,fp);fclose(fp);printf(最高的分为：dnn,i);printf(t 按 1 返回nn);printf(t 按 2 退出nn);s=getche();switch(s)case 1:boundary();break;case 2: end();break;void boundary。/开始界面system(cls);char s;color(14);printf(tt 欢迎来玩！! nn);printf(tt1：开始nn);printf(tt2：查看成绩nn);printf(tt3：退出nn);pr
