这学期java最后让编一个程序，第一次写这么多行的程序，收获很大。
写的第一个博客，以后要经常写，记录自己遇到的问题和解决方法。

问题

1.闪烁

解决方法

1.使用双缓冲，但是没有效果
2. 继承JPanel类，成功

2.子弹不能多发

解决方法

建立子弹数组，由开火函数写在飞机类中，所有画图都调到游戏主窗口类的paint中。

1.主菜单

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
/** 主菜单，主方法类*/
public class Welcome extends JFrame{Image background2=GameUtile.getImage("image/menuback.png");public Welcome() {//大小this.setSize(800,600);//标题this.setTitle("雷电");//窗口居中this.setLocationRelativeTo(null); //可见this.setVisible(true);JButton startGame=new JButton("开始游戏");JButton infoGame=new JButton("玩法介绍");JButton endGame=new JButton("退出");startGame.setBounds(350, 290, 100, 50);infoGame.setBounds(350, 350, 100, 50);endGame.setBounds(350, 410, 100, 50);this.add(startGame);this.add(infoGame);this.add(endGame);this.setLayout(null);        ImageIcon img1=new ImageIcon("src/image/menuback.png");JLabel la3=new JLabel(img1);la3.setBounds(0,0,800,600);this.getLayeredPane().add(la3,new Integer(Integer.MIN_VALUE)); getContentPane().add(la3);this.setResizable(false);startGame.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stub/*点开始游戏，销毁主菜单窗口* 创建选择模式窗口*/dispose();ChooseModel cm=new ChooseModel();}});infoGame.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stub/** 点击玩法介绍，创建玩法介绍窗口*/InfoFrame infoframe=new InfoFrame();}});endGame.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubdispose();}});}public static void main(String[] args) {// TODO Auto-generated method stubWelcome welcome=new Welcome();//        GameWindow gw=new GameWindow();//      gw.MyWindow();//gw.setVisible(true);}}

2.模式选择菜单

package com.lhyltzj.www;import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
/** 模式选择类* */
public class ChooseModel extends JFrame{public ChooseModel(){this.setSize( 500, 400);this.setTitle("模式选择");this.setVisible(true);this.setLocationRelativeTo(null); this.setLayout(null);JButton normal=new JButton("闯关模式");JButton endless=new JButton("无尽模式");normal.setBounds(200, 100, 100, 50);endless.setBounds(200, 200, 100, 50);this.add(normal);this.add(endless);ImageIcon img1=new ImageIcon("src/image/chooseback.png");JLabel la3=new JLabel(img1);la3.setBounds(0,0,700,800);this.getLayeredPane().add(la3,new Integer(Integer.MIN_VALUE)); getContentPane().add(la3);this.setResizable(false);this.setLayout(null);normal.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stub/** 闯关模式* 传参数false*/dispose();GameWindow gw=new GameWindow();gw.MyWindow(false);}});endless.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stub/** 无尽模式* 传参数ture*/dispose();GameWindow gw=new GameWindow();gw.MyWindow(true);}});}}
