写了个贪吃蛇

一个简单的在终端运行的贪吃蛇

效果如下：

代码：

#include<iostream>
#include<conio.h>
#include<windows.h>
#include<random>
#include<ctime>
#include<chrono>
#include<sstream>
using namespace std;#define height 20
#define wdith 30//头部和坐标
char head = '@';
int pos_x = wdith / 2;
int pos_y = height / 2;//身体长度和坐标，默认为3
int length = 3;
int body_x[100];
int body_y[100];// int food_num = 3;
// int food_x[100];
// int food_y[100];//食物坐标
int food_x;
int food_y;//分数
int score = 0;//方向，默认向上
int dir = 1;//生成随机数，获取食物坐标
int randomNumGen(int l,int r){static default_random_engine e(chrono::steady_clock::now().time_since_epoch().count());uniform_int_distribution<int> u(l,r);return u(e);
}//获取控制台句柄
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);//光标移动函数，将输出光标移动到指定位置
void gotoXY(int x,int y){COORD pos = {(SHORT)x,(SHORT)y};SetConsoleCursorPosition(hConsole,pos);
}bool isOnBody(int x,int y){if(x == pos_x && y == pos_y){return true;}for(int i = 0;i<length;i++){if(x == body_x[i] && y == body_y[i]){return true;}}return false;
}//生成食物
void genFood(){int x = randomNumGen(2,wdith-1);int y = randomNumGen(2,height-1);//防止生成到蛇身上if(isOnBody(x,y)){genFood();}food_x = x;food_y = y;
}//墙壁检测
// bool noWallY(int pos){
//     return (pos < height && pos >= 0);
// }
// bool noWallX(int pos){
//     return (pos < wdith-1 && pos > 0);
// }//游戏结束条件
