Windows程序设计 贪吃蛇c

Windows程序设计 贪吃蛇c

看Windows程序有段时间了，终于动手写东西。

贪吃蛇算是一个开始吧，下面的贪吃蛇很简单，也有很多地方需要修改，还有情况没有考虑QAQ 但这不是我的目的了。

。

。

思路很简单：建个链表储存蛇身节点即可。

#include <windows.h>

#include <time.h>

#define ID_TIMER    1

#define TIMERSET    600

char    score,temp=;

int     flag,tempx,tempy,

        foodx,foody,key;//运动方向，食物坐标，标记

bool    havebody[][];

bool    over = false;

struct Snake

{

    Snake *next;

    int x;

    int y;

};

struct Snake *head;

struct Snake *creat()//链表初始化

{

    struct Snake *p1,*p2,*p3;

    head=(struct Snake*)malloc(sizeof(Snake));

    p1=(struct Snake*)malloc(sizeof(Snake));

    p2=(struct Snake*)malloc(sizeof(Snake));

    p3=(struct Snake*)malloc(sizeof(Snake));

    head->x=;head->y=;

    head->next=p1;

    p1->x=;p1->y=;

    p1->next=p2;

    p2->x=;p2->y=;

    p2->next=p3;

    p3->x=;p3->y=;

    p3->next=NULL;

    return head;
