本文实例为大家分享了C++实现贪吃蛇游戏的具体代码，供大家参考，具体内容如下

刚学完了C语言，便尝试的写了贪吃蛇的代码，但是效果不佳，很多的bug，所以，这个学了C++，便重新的写了这个小游戏，用类来封装！

先是头文件：

struct Snake

{

int x, y;

};

class snake

{

public:

snake() //构造函数

{

length = 3;

s[2].x = 10;

s[2].y = 10;

s[1].x = 9;

s[1].y = 10;

s[0].x = 8;

s[0].y = 10;

up = right = left = down = 0;

}

~snake(){}

void display(); //显示蛇身函数

void Rightmove(); //右移函数

void Leftmove(); //左移函数

void Upmove(); //上移函数

void Downmove(); //下移函数

int cheak(); //检查是否撞墙或撞到自身

void creat_food(); //产生食物

int eat_food(); //吃食物

private:

struct Snake s[100]; //先定义蛇身最长100

int length; //当前蛇长度

int x3, y3; //食物坐标

int up, down, right, left; //蛇的状态，是上移还是下移或...

};

void make_frame(); //打印框架的函数

void show(); //游戏开始倒计时函数

void gameover(); //游戏结束函数

下面是各个函数的实现的cpp文件：

# include

# include

# include

# include "snake.h"

# define MaxLen 20

# define MaxWen 30

using namespace std;

HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE); //获取句柄

void gotoxy(HANDLE hOut, int x, int y) //输出位置的函数

{

COORD pos;

pos.X = x;

pos.Y = y;

SetConsoleCursorPosition(hOut, pos);

}

void snake::display() //打印蛇身

{

for (int i = length - 1; i >= 0; i--)

{

if (i == length - 1) //打印蛇头

{

gotoxy(hOut, s[i].x, s[i].y);

cout << char(15);

}

else //打印蛇身

{

gotoxy(hOut, s[i].x, s[i].y);

cout << '*';

}

}

gotoxy(hOut, 0, 22);

}

void snake::Rightmove() //右移

{

right = 1; up = down = left = 0;

int x1, x2, y1, y2;

x1 = x2 = s[length - 1].x;

y1 = y2 = s[length - 1].y;

s[length - 1].x++; //蛇头x坐标自增

for (int i = length - 2; i >= 0; i--) //除了蛇头，其他的结点都等于它的上一个结点的坐标

{

x2 = s[i].x; y2 = s[i].y;

s[i].x = x1; s[i].y = y1;

x1 = x2; y1 = y2;

下面是游戏的截图：

控制台的实现，不是很美观，主要是由于上下和左右的间隙不一样大，所以看起来不是很好看，但总体还是实现了贪吃蛇！
