所用知识:

  1. 一维数组的使用
  2. 结构体的使用
  3. 播放音乐函数的使用
  4. 电脑按键的检测
  5. 窗口光标坐标函数的使用

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x
	coord.Y = y; //纵坐标y
	SetConsoleCursorPosition(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

代码

game.cpp

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>//坐标的API
#include <conio.h>//按键
#include <time.h>//产生随机数要用到
#include"game.h"

SNAKE snake;//定义SNAKE 类型的snake,不可在.h文件中定义
FOOD food;//同上
int score = 0;//得分
char key = 'W';//键盘获得的方向
char tempkey = 'W';//当前蛇行进方向
bool changeflag = false;//用于有无吃到食物的标志

//到某一指定坐标的函数
void gotoxy(int x, int y)

}
//画地图
void drawmap()
