写一个简单的打飞机游戏（Ｄｏｓ界面）

首先分析打飞机游戏的要素：

1、计分。

2、是否被敌机碰撞摧毁（被击中未实现。。。）

3、发射子弹。

（因为是一个简化的游戏。。要素很少。。）

思路：将布局采用二维数组，用*号代表玩家，0代表敌机，敌机用rand()函数设定位置。

ps：代码很乱，有很多不应该在Barod类中实现出现的方法，应该放在player类中实现。

Barod提供布局、输出、设置位置、获取位置。

player类提供了判断是否被碰撞，玩家用wasd控制数组上的移动，子弹射击，控制敌机下落速度。

代码如下：

#pragma once
#include<stdlib.h>//使用该头文件中的rand()函数
#include<iostream>
#include <conio.h> //通过控制台输入输出流头文件，调用kbhit()刷新查看是否输入，对控制台进行刷新,
#include <windows.h>
using namespace std;
void gotoxy(int x, int y)  //光标移动到(x,y)位置,从而达到刷新控制台的视觉效果
{
HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
COORD pos;
pos.X = x;
pos.Y = y;
SetConsoleCursorPosition(handle, pos);
}
