源码来自罗德岛公共休息室的《C语言/C++经典游戏项目教程—飞机大战，非常适合小白入门练习》。
将敌机的飞机模型改成了狗头表情包，因为某人经常给我发狗头，我就想要做一个打爆狗头的小程序，哼！！
游戏开始界面：
飞机发射子弹
狗头被击打后
本代码编程使用的软件为Vistual Studio,感觉没有pycharm好用，不过用习惯了也还好吧。
完整代码如下：

主要思路是
1、制作飞机，子弹，敌机。
2、定义飞机坐标，子弹坐标，敌机坐标。
3、键盘上下左右空格对应飞机移动和发射子弹。
4、敌机出现位置随机，位置会随时间变化向下移动。
5、子弹位置随时间变化向上移动。
6、当子弹位置与敌机位置重合时，子弹消失，敌机状态发生改变。
