使用JAVA基础知识做的一个增强版飞机大战，仙侠主题，增设关卡BOSS等

第一次在CSDN写博客 不足之处请大家多多指教
先放一下效果图

以下是部分代码介绍
首先定义播放音乐和图片的工具类，都是使用静态代码块来加载资源

   /**读取图片的方法*/

			BufferedImage img = ImageIO.read(Flys.class.getResource(fileName));

		}catch(Exception e){
			e.printStackTrace();
			throw new RuntimeException();
		}
	}
}

package Game;

import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;

public class Music {
	 public static AudioClip ac ;
	 public static AudioClip bg ;//背景音乐
	 public static AudioClip dj ;
	 public static AudioClip fs ;
	 public static AudioClip ly ;
	 public static AudioClip jf ;
	 public static AudioClip my ;
	 public static AudioClip gd ;
	    static{
	    	
				try {
					ac = getMusic("src/鹰啼.wav");
					bg = getMusic("C:\\Users\\chengcheng\\Desktop\\迪迦奥特曼.wav");

	    public static AudioClip getMusic(String path) throws Exception {
	    	@SuppressWarnings("all")
	        AudioClip ac = Applet.newAudioClip(new File(path).toURI().toURL());
	        return ac;
	    }


}

接着是所有飞行物的父类，存放共有的属性和行为

package Game;

import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.util.Random;


public abstract class Flys {
	int hp = 1;
	public static int k = 0;
	public static final int LIFE = 0;//代表活着的状态
	public static final int DEAD = 1;//代表死亡爆炸状态
	public static final int REMOVE = 2;//代表移除状态
	int state = LIFE;//默认当前状态为LIFE
	protected int high;
	protected int width;
	protected int x;
	protected int y;
	BufferedImage img;
	/** 专门为英雄机，天空，子弹提供的构造方法*/
public Flys( int x, int y,int width,int high) {
	super();
	this.high = high;
	this.width = width;
	this.x = x;
	this.y = y;
}
/**专门为大小敌机和小蜜蜂提供的构造 */
  public Flys(int high, int width) {
	super();
	Random r = new Random();
	this.high = high;
	this.width = width;
	x = r.nextInt(World.WIDTH-width);
	y = -high;
  }
  /**因为每个对象获取图片的方式不一致，所以父类中设计获取图片的抽象方法*/
  public abstract BufferedImage getImage();
  public void paint(Graphics g){
	g.drawImage(getImage(),x,y,null);
  }
  public abstract void step();
  public boolean isLife(){
	  return state==LIFE;//状态为life返回true
  }
  public boolean isRemove(){
	  return state==REMOVE;//状态为remove返回true
  }
  public boolean isDead(){
	  return state==DEAD;//状态为dead返回true
  }
  public boolean hit(Flys other){
		int x1 = this.x-other.width;
		int x2 = this.x+this.width;
		int y1 = this.y-other.high;
		int y2 = this.y+this.high;
		int x = other.x;
		int y = other.y;
		
		return x>=x1 && x<=x2 && y>=y1 && y<=y2;
	}
  public void goDead(){
		state = DEAD;
	}
  //检测是否越界的方法
 public boolean isBound(){
	return y>=World.HIGH;
	 
 }
 public int Hp(){
	 hp--;
	 return hp;
 }
 
}

接下来是敌机类，分为大小敌机和奖励机三个，基本思路一致，使用不同的图片相互切换实现图片的动态展示
在这里贴出大敌机类的代码

package Game;

import java.awt.Graphics;
import java.awt.image.BufferedImage;

public  class BigAirplane extends Flys implements EnemyGetScore{

	
	public BigAirplane() {
		super(160, 160);
		if(Flys.k==4){
			width = 220;
			high = 220;
		}
		hp = 6+2*Flys.k;
	}

	public void step(){
		y += 6+Flys.k;
	}
	@Override
	public void paint(Graphics g) {
		g.drawImage(getImage(), x, y, width,high,null);
	}
	int change = 0;
	private int index = 0;
	int index1 = 0;
	int index2 = 0;
	int index3 = 0;
	int index4 = 0;
	/** 重写画大敌机的方法 */
	@Override
	public BufferedImage getImage() {
		change++;
		if(change%20==0){
			index2++;
			index1++;
			index3++;
			index4++;
			index++;
		}
		if(isLife()){
			if(Flys.k==0)
			return Images.bairplanetest[index%4];
			else if(Flys.k==1)
				return Images.bairplanetest2[index2%6];
			else if(Flys.k==2)
				return Images.bairplanetest3[index3%8];
			else if(Flys.k==3)
				return Images.bairplanetest4[index2%6];
			else
				return Images.bairplanetest5[index4%14];
		}else if(isDead()) {
			 img = Images.boom[index%6];
			if(index%6==0){
				//index=0;
			state = REMOVE;
			}
			return img;
		}
			return null;
		
	}

	@Override
	public int getscore() {
		return 3*Flys.k;
	}

	@Override
	public int Hp() {
		hp--;
		return hp;
	}
}

以下是英雄机的代码，

package Game;

import java.awt.image.BufferedImage;
import java.util.LinkedList;



public class Hero extends Flys{
	int bx = this.width/4;
	int by = 20;
	int life = 30;
	int fire=1;
	boolean protect = false;//英雄机的受保护状态
	boolean help = false;
	boolean skill = true;
	public Hero() {
		super(380,800,150,200);
	}
	public void moveMouse(int x,int y){
		this.x = x-this.width/2;
		this.y = y-this.high/2;
	}
   int index = 0;
   int count = 0;
	@Override
	public BufferedImage getImage() {
		
		if(isLife()){
			count++;
			if(count%30==0)
				index++;
			if(!protect)
			return Images.heros[index%Images.heros.length];
			else
				return Images.protect[index%11];
		}else if(isDead()){
			return Images.boom[index%6];
		}
		
		return null;
		
	}
	//英雄机发射子弹的方法
	public LinkedList<Bullet> shoot() {
		 if(fire>=4){
			LinkedList<Bullet> five = new LinkedList<Bullet>();
			five.add(new Bullet(x+bx-5,y+by,0));
			five.add(new Bullet(x+2*bx+5,y+by,0));

				five.add(buhelp2);
			}
			return five;
		}else if(fire==3){
			LinkedList<Bullet> three = new LinkedList<Bullet>();
			three.add(new Bullet(x+bx-5,y+by,0));
			three.add(new Bullet(x+2*bx+5,y+by,0));
			three.add( new Bullet(x+bx+20,y+by,0));
			if(help) {
				Bullet buhelp = new Bullet(x-150,y);
				three.add(buhelp);
				Bullet buhelp2 = new Bullet(x+55,y);
				three.add(buhelp2);
			}
			return three;
		}else if(fire==2){
			LinkedList<Bullet> two = new LinkedList<Bullet>();
			two.add(new Bullet(x+bx-5,y+by,0));
			two.add(new Bullet(x+2*bx+5,y+by,0));
			if(help) {

			}
			return two;
		}else{
			LinkedList<Bullet> one = new LinkedList<Bullet>();
			one.add(new Bullet(x+bx+20,y-by,0));
			if(help) {
				Bullet buhelp = new Bullet(x-150,y-100);
				one.add(buhelp);
				Bullet buhelp2 = new Bullet(x+55,y-100);
				one.add(buhelp2);
			}
			
			return one;
		}
		

	}
	/**
	 * 英雄机增加生命
	 */
	public void addLife(){
		life++;
	}
	/**

	public void subLife(){

	}
	/**

	public int getLife(){
