飞机大战实验报告专业：网络工程132班学号：*********姓名：孙**计算机科学与技术学院二零一六年十二月一、软件运行所需要的软硬件环境本系统是以Windows系统为操作平台，用Java编程语言来实现本系统所需功能的。

本机器的配置如下：处理器：CORE i7主频：1.2Hz以上内存：4G以上硬盘：HHD50G编程语言：Java开发环境：windows7开发软件：Eclipse Mars二、游戏流程1.用户打开游戏，进入开始菜单。

2.用户点击开始游戏按钮，进入游戏界面；3.用户通过触屏方式控制玩家飞机上下左右移动，躲避与子弹相撞；4.游戏失败后，显示本次游戏得分，用的秒数和水平；5.退出游戏三、主要代码1、准备代码设置窗口使用双缓冲使飞机不闪烁Constant设置窗口大小package com.ahut.准备代码;public class Constant {public static final int GAME_WIDTH = 350;public static final int GAME_HEIGHT = 600;}package com.ahut.准备代码;import java.awt.Image;import java.awt.image.BufferedImage;import java.io.IOException;import .URL;public class GameUtil {private GameUtil () {}public static Image getImage(String path) {BufferedImage bi = null;try {URL u = GameUtil.class.getClassLoader().getResource(path);bi = javax.imageio.ImageIO.read(u);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return bi;}}package com.ahut.准备代码;import java.awt.Frame;import java.awt.Graphics;import java.awt.Image;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;public class MyFrame extends Frame{public void lauchFrame() {setSize(Constant.GAME_WIDTH, Constant.GAME_HEIGHT);setLocation(100, 100);setVisible(true);new PaintThread().start();addWindowListener(new WindowAdapter() {@Overridepublic void windowClosing(WindowEvent e) {System.exit(0);}});}private Image offScreenImage = null;public void update(Graphics g) {if (offScreenImage == null)offScreenImage = this.createImage(Constant.GAME_WIDTH, Constant.GAME_HEIGHT);Graphics gOff = offScreenImage.getGraphics();paint(gOff);g.drawImage(offScreenImage, 0, 0, null);}class PaintThread extends Thread {public void run() {while (true) {repaint();try {Thread.sleep(40);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}}主代码飞机：package com.ahut.plane;import java.awt.Graphics;import java.awt.event.KeyEvent;import com.ahut.准备代码.GameUtil;public class Plane extends GameObject {private boolean left, up, right, down;private boolean live = true;public void draw(Graphics g) {if (live) {g.drawImage(img, (int)x, (int)y, null);move();}}public void addDirection(KeyEvent e) {switch (e.getKeyCode()) {case KeyEvent.VK_LEFT: //左left = true;
