贪吃蛇，但可以双人

首先声明本代码修改于该文章，只是稍微增加一些其它功能：http://t.csdn.cn/zvvh9

我们需要下载一个插件，名字叫做EasyX.

如图：

 点进去，然后点击下载

随后安装，之后打开

 点击下一步，

 之后点安装就行了，最好第一个和第二个都安装起

之后打开visual stduio 2022,新建项目。

之后点开项目，点击属性如图：

 然后将SDL检查改为否，并且将字符集改为使用多字节字符集：

 随后创建一个game.h的头文件，game.cpp的源文件，再创建一个main.cpp的源文件.如图：

 其中,game.h文件下的代码为：

#include
#include
#include
#include		
#include
#define SNAKE_SIZE 360int Initgame(int a);
void Drawgame(int a);
void KeyControl(int a);
void snakemove(int a);
void Eatfood();

game.cpp文件的代码为：

void Eatfood()

}

main.cpp文件的代码为：

#include"game.h"
int main()
{int a;printf("请输入你想挑战的难度:\n");printf("1.简单\n");printf("2.普通\n");printf("3.困难\n");printf("4.双人模式\n");scanf_s("%d", &a);int c=Initgame(a); while (c){Drawgame(a);KeyControl(a);snakemove(a);Eatfood();Sleep(80);}return 0;
}

这样，就可以运行起了

简单模式下：

 普通模式下：

困难模式下：

 双人模式下：

 注意：开始时需要将字母改为大写，其中白色的蛇的控制上下左右的按键为WSAD，空格为暂停。

控制另一条蛇的按键为IKJL，空格为暂停.

不同模式下蛇的大小和蛇行进速度不一样。

欢迎大家修改代码，让其变得更加有趣。
