JAVA飞机大战游戏
简介：本人在本学期，通过JAVA实训，做了一款Java桌面程序游戏（飞机大战），设计思想和自己之前的C语言一样。还是通过多线程技术为核心。因为是学校实训内容，主要目的是巩固JAVA的学习，利用到了Java中面向对象的思想（继承，封装，多态），文件的读取，数组，集合（List）, 线程同步，JAVAFx图形界面，鼠标事件监听等。
游戏规则设计
主要是英雄机和敌机对战，英雄机和敌机都可以发射子弹，并且英雄机可以和敌机对掉子弹。英雄机打爆某一特殊敌机时，有奖励作用，分为加一条命，或者加火力值。
先看效果图
核心技术分析
Canvas canvas = new Canvas(ShootGame.WIDTH, ShootGame.HEIGHT);
GraphicsContext gc = canvas.getGraphicsContext2D();
gc.drawImage(image, 110, 375);通过JAVAFx的二维画笔，画出资源路径下的图片文件。
再通过Timer 定时器，通过不断的去绘制图片，达到动态效果，再监听鼠标事件，坐标监听，来完成游戏规则。

主界面代码及布局文件
public class Main extends Application {
private static final int WIDTH = 400;
private static final int HEIGHT = 654;
private static Image background = Tool.readImg("main2.jpg"); @Override

ObservableList<Node> children = ((Pane) root).getChildren();
Button plane = (Button) children.get(1);
plane.setOnAction(event -> {

/**
