上午没事刷到网上最近炒热了一些简单的小游戏和爱心代码，单身8个月了，对爱心代码不是很感冒，所以想蹭个热度，写一个飞机大站来玩玩。

首先，分析小游戏需要那些技术与怎么设计：

窗体，因为是java小游戏，那么就需要用到java的swing或者是Fx包里的相关图形化方法。

多线程，因为不可能是只有我们的飞机在飞，敌方也有飞机，子弹也需要飞行。

图片读取：需要将图片放入窗体中，所以需要借助画布，但是前提是我们需要将图片解析出来。

实体设计：越成熟的游戏设计的敌方飞机与我方飞机的功能与属性越多，这都需要基于实体实现。

那么基于以上几个点，我们首先就是建立一个可视化的窗体出来：

借助所谓的JFrame窗体类实现（也可继承来实现）：

public static void main(String[] args) throws IOException {JFrame frame = new JFrame();GamePanel gamePanel = new GamePanel();frame.add(gamePanel);frame.setSize(576, 840);frame.setTitle("战机");frame.setLocationRelativeTo(null);frame.setVisible(true);frame.setDefaultCloseOperation(3);gamePanel.move();frame.addMouseListener(gamePanel);frame.addMouseMotionListener(gamePanel);}

因为是一个窗体，所以我们需要借助画布对象来给窗体内部添加一些元素。也需要借助鼠标监听的相关接口对鼠标事件进行业务重写。

这里我们直接挂出来（相关代码的释疑都在注释里）：

画布类：
