篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了c语言 贪吃蛇 程序相关的知识，希望对你有一定的参考价值。
参考技术A基本思路：
蛇每吃一个食物蛇身子就增加一格，用UP, DOWN, LEFT, RIGHT控制蛇头的运动，而蛇身子跟着蛇头走，每后一格蛇身子下一步走到上一格蛇身子的位置，以此类推。
#include <stdio.h>
#include <conio.h>
#include <windows.h>
#define BEG_X2
#define BEG_Y1
#define WID20
#define HEI20
HANDLE hout;
typedef enum UP, DOWN, LEFT, RIGHT DIR;
typedef struct Snake_body
COORD pos;//蛇身的位置
struct Snake_body *next;//下一个蛇身
struct Snake_body *prev;//前一个蛇身
SNAKE, *PSNAKE;
PSNAKE head = NULL;//蛇头
PSNAKE tail = NULL;//蛇尾
//画游戏边框的函数
void DrawBorder()
int i, j;
COORD pos = BEG_X, BEG_Y;
for(i = 0; i < HEI; ++i)
SetConsoleCursorPosition(hout, pos);
for(j = 0; j < WID; ++j)
if(i == 0)//第一行
if(j == 0)
printf("┏");
else if(j == WID - 1)
printf("┓");
else
printf("━");
else if(i == HEI - 1)//最后一行
if(j == 0)
printf("┗");
else if(j == WID - 1)
printf("┛");
else
printf("━");
else if(j == 0 || j == WID - 1)//第一列或最后一列
printf("┃");
else
printf(" ");
++pos.Y;
//添加蛇身的函数
void AddBody(COORD pos)
PSNAKE pnew = (PSNAKE)calloc(1, sizeof(SNAKE));
pnew->pos = pos;
if(!head)
head = tail = pnew;
else
pnew->next = head;//新创建蛇身的next指向原先的蛇头
head->prev = pnew;//原先的蛇头的prev指向新创建的蛇身
head = pnew;//把新创建的蛇身作为新的蛇头
SetConsoleCursorPosition(hout, head->pos);
printf("◎");
//蛇身移动的函数
void MoveBody(DIR dir)
PSNAKE ptmp;
COORD pos = head->pos;
switch(dir)
case UP:
if(head->pos.Y > BEG_Y + 1)
--pos.Y;
else
return;
break;
case DOWN:
if(head->pos.Y < BEG_Y + HEI - 2)
++pos.Y;

else

break;
AddBody(pos);//添加了一个新的蛇头
ptmp = tail;//保存当前的蛇尾
tail = tail->prev;
if(tail)
tail->next = NULL;
SetConsoleCursorPosition(hout, ptmp->pos);
printf(" ");
free(ptmp);
int main()
int ctrl;
DIR dir = RIGHT;//初始蛇的方向是向右的
COORD pos = BEG_X + 2, BEG_Y + HEI / 2;
system("color 0E");
system("mode con cols=90 lines=30");
hout = GetStdHandle(STD_OUTPUT_HANDLE);
printf(" ------------贪吃蛇的移动------------");
DrawBorder();
//自定义几个蛇的身体
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
pos.X += 2;
AddBody(pos);
//控制蛇的移动
while(ctrl = getch())
switch(ctrl)
case 'w':
if(dir == DOWN)
continue;
dir = UP;
break;
case 's':
if(dir == UP)
continue;
dir = DOWN;
break;
case 'a':
if(dir == RIGHT)
continue;
dir = LEFT;
break;
case 'd':
if(dir == LEFT)

dir = RIGHT;
break;
case 'q':
return 0;
MoveBody(dir);
return 0;
扩展资料：
实现逻辑
1，可以设置光标，就能实现制定位置打印制定符号。
2，涉及一个结构体，包含两个元素坐标元素和一个结构体指针。
3，结构体串联形成链表，遍历获取成员坐标，打印符号得到蛇身。
4，不断的加头，去尾，重新遍历坐标，再打印形成蛇的移动。
5，食物产生的位置判定，不能越界，也不能与蛇身体重合。
6，蛇的转向判定，一条规则，不允许倒退。
7，转向的实现，跟行进方向决定新的关节坐标（当前头的上下左右）
8，死亡检测，是否头节点坐标是否与墙壁重合，是否与身体其他关节重合。
9，加速减速，设置刷新休眠时间实现。

C语言贪吃蛇
基于C语言编写的贪吃蛇
开发环境：VS2019
这是一个基于C语言链表开发的贪吃蛇游戏
其实贪吃蛇游戏要解决的主要问题就是
1、这个游戏的基本组成元素和架构
2、如何初始化贪吃蛇并正常行走
3、如何判断事件发生
代码中运用到了键盘虚拟键判断、终端窗口大小的改变、光标的定位以及输出字体的颜色
