C++控制台实现贪吃蛇游戏

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 <iostream>
# include <Windows.h>
# include <time.h>
# 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;
}
gotoxy(hOut, x2, y2); //消除蛇移动遗留的 ‘*'
cout << ' ';
