相关函数讲解

1.光标移动到某一指定坐标的函数

#include <windows.h>//坐标的API

void gotoxy(int x, int y)
{HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);COORD coord; //定义结构体coord (坐标系coord)coord.X = x; //横坐标xcoord.Y = y; //纵坐标ySetConsoleCursorPosition(handle, coord); //移动光标
}

2.kbhit按键检测函数

#include <conio.h>//按键

引用一下其他网友的解答：

#include <conio.h>
#include
using namespace std;
int main()
{
while(!kbhit()) //当没有键按下
{
cout<<“无键按下”<<endl;
}
cout<<“有键按下”<<endl; //有键按下时输出这
system(“pause”);
}
kbhit() 在执行时,检测是否有按键按下,有按下返回非0值，一般是1
没有按下返回0;是非阻塞函数
getch() 在执行时,检测按下什么键,如果不按键该函数不返回;是阻塞函数
类似地
在Tc2.0中有一个处理键盘输入的函数bioskey();
int bioskey(int cmd);
当cmd为1时，bioskey()检测是否有键按下。没有键按下时返回0；有键按下时返回按键码(
任何按键码都不为0)，但此时并不将检测到的按键码从键盘缓冲队列中清除。 是非阻塞参数。
当cmd为0时，bioskey()返回键盘缓冲队列中的按键码，并将此按键码从键盘缓冲队列中清
除。如果键盘缓冲队列为空，则一直等到有键按下，才将得到的按键码返回。是阻塞调用。
//个人理解kbhit()有点像bioskey(1)
具体搜索bioskey词条吧 ：）

3.playsound函数
引用一下这个函数的详细说明
所需头文件，顺序要这样子

#include <windows.h>//坐标的API
#include <MMSystem.h>
#pragma comment(lib,"winmm.lib")

在main函数里面使用，m1.wav为文件名，我放在跟cpp文件同目录下来了

PlaySound(L"m1.wav", NULL, SND_FILENAME | SND_ASYNC | SND_LOOP);//播放声音

基本要素

1. 画地图（包含刚开始的画蛇和食物）
2. 按键检测
3. 产生食物
4. 判断蛇的状态
