飞机大战Java源代码

很快，大二这个学期就要完结了，所学的大部分课程都快要结束了，Java课程也是如此。而Java这门课程也有一个惯例就是要做一个课程设计，老师给了我们三个选择，分别是飞机大战、推箱子和学生成绩管理系统。在经过深思熟虑后，我选择了飞机大战。一方面是觉得他比较有趣和好玩，另一方面，觉得这难度也适中，所以就选择了它。

现在，我对这个飞机大战进行解说。主要分为六个部分，分别是底层窗口和容器类、各种组件类、碰撞类、监听器类、线程类和音效媒体类。

游戏运行图片如下：

一底层容器和窗口

在利用Java制作飞机大战这个游戏时，首先就要构造一个窗口。只有创建了窗口之后，你后面的游戏背景图片、飞机、子弹和空投等等，才能放入界面中。

Main主程序：程序的运行由此开始。

public class Main {public static void main(String[] args) {new BaseFrame();String bg="Music/bg.wav";Music music = new Music();music.playMusic(bg);}}

在底层容器中，我是利用JFrame去构造。创建BaseFrame类去继承JFrame，然后再对鼠标设立监听器去控制英雄机的移动。后面再在创建MyPanel类去继承JPanel去实现窗口。
BaseFrame类:

import java.awt.*;
import javax.swing.*;
public class BaseFrame extends JFrame{public static int frameWidth=345;public static int frameHeight=575;public Graphics g;public MyPanel myPanel;//存放的是鼠标监听器public FrameMouseListener frameMouseListener;public FrameMouseClick frameMouseClick;//设置监听器public void setTouchListener1() {this.frameMouseListener=new FrameMouseListener();this.frameMouseListener.baseFrame=this;//注册监听器this.addMouseMotionListener(this.frameMouseListener);}public void setTouchListener2() {this.frameMouseClick=new FrameMouseClick();this.frameMouseClick.baseFrame=this;//注册监听器this.addMouseListener(this.frameMouseClick);}public BaseFrame() {super("飞机大战");//获得屏幕的分辨率Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();//设置窗口的大小和位置this.setBounds(((int)screenSize.getWidth()-frameWidth)/2,50,frameWidth,frameHeight);//设置布局方式this.setLayout(null);//创建一个MyPanel对象this.myPanel=new MyPanel();//设置MyPanel对象的大小和位置this.myPanel.setBounds(0,0,frameWidth,frameHeight);//设置监听器setTouchListener2();setTouchListener1();//将组件添加到窗口this.add(this.myPanel);//显示窗口this.setVisible(true);//设置窗口的关闭行为this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}}

MyPanel类：去存放飞机、子弹等等小组件，里面利用的计时器timer去控制整个游戏的进行，包括背景图的移动，子弹的发射，敌机的前进，空投的下落等等。

}

二各种组件类

各种组件类中就比较多了，包括英雄机类，子弹类，空投类，boss类等等，以下一一通过代码展示。
英雄机类：

import java.awt.*;
import javax.swing.*;public class Player {public MyPanel myPanel;public int width=60;public int height=61;public int x;public int y;public int attackMode=1;//火力等级public int imageindex=0;//存放当前图片下标public Image[] images=new Image[] {Toolkit.getDefaultToolkit().getImage("Picture/player1.png"),Toolkit.getDefaultToolkit().getImage("picture/player2.png"),Toolkit.getDefaultToolkit().getImage("Picture/playerX.png")};public Player(MyPanel myPanel) {this.myPanel=myPanel;this.x=(BaseFrame.frameWidth-this.width)/2;this.y=(BaseFrame.frameHeight-this.height+260)/2;}public void drawSelf(Graphics g) {g.drawImage(this.images[imageindex], x, y, width, height, null);if(this.myPanel.timer%50==0) {if(this.myPanel.score<=300) {imageindex++;if(this.imageindex==2)this.imageindex=0;}else {imageindex=2;}}}
}

敌机类：

import java.awt.*;
import java.util.Random;import javax.swing.*;
public class Enemy {public MyPanel myPanel;public int width=40;public int height=25;public int x;public int y;public Image image;public Enemy(MyPanel myPanel) {this.myPanel=myPanel;this.image=Toolkit.getDefaultToolkit().getImage("Picture/enemy.png");}public void drawSelf(Graphics g) {g.drawImage(this.image, x, y, width, height, null);if(this.myPanel.timer%1==0)y++;if(y+height>BaseFrame.frameHeight)this.myPanel.enemies.remove(this);}
}

boss类：

import java.awt.*;
public class Boss {public MyPanel myPanel;public int width=100;public int height=73;public int x;public int y;public Image image;public int flag=1;public int lives=500;public Boss(MyPanel myPanel) {this.myPanel=myPanel;this.image=Toolkit.getDefaultToolkit().getImage("Picture/Boss.png");this.x=(BaseFrame.frameWidth-this.width)/2;this.y=0;}public void drawSelf(Graphics g) {g.drawImage(this.image, x, y, width, height, null);if(this.myPanel.timer%3==0&&this.y<=100&&lives>0)this.y++;if(lives<0)this.y--;if(this.myPanel.timer%3==0&&this.y>100) {if(this.x+this.width>BaseFrame.frameWidth)flag=0;if(this.x==0)flag=1;if(flag==1)this.x++;if(flag==0)this.x--;}}
}

空投类：

import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.util.Random;public class Airdrop {public MyPanel myPanel;public int width=40;public int height=40;public int x;public int y;public int flag=0;Random ran;public Image image;public Airdrop(MyPanel myPanel) {this.myPanel=myPanel;this.image=Toolkit.getDefaultToolkit().getImage("Picture/airdrop.png");}public void drawSelf(Graphics g) {g.drawImage(this.image, x, y, width, height, null);if(this.myPanel.timer%3==0) {y++;if(flag==0) {x++;}if(flag==1) {x--;}if(this.x+40>BaseFrame.frameWidth)flag=1;if(this.x<0)flag=0;}if(y+height>BaseFrame.frameHeight)this.myPanel.airdrops.remove(this);}}

英雄机子弹类：

import javax.swing.*;
import java.awt.*;
public class Bullet {public MyPanel myPanel;public int width=6;public int height=14;public int x;public int y;public int index=0;public Image[] bulletImage=new Image[] {Toolkit.getDefaultToolkit().getImage("Picture/ammo.png"),Toolkit.getDefaultToolkit().getImage("Picture/bullet1.png")};public Bullet(MyPanel myPanel) {this.myPanel=myPanel;}//画子弹public void drawSelf(Graphics g) {g.drawImage(this.bulletImage[index], x, y, width, height, null);if(this.myPanel.timer%1==0)y--;if(y<0)this.myPanel.bullets.remove(this);if(this.myPanel.score>100)index=1;}
}

boss子弹类：

import java.awt.*;
public class BossBullet {public MyPanel myPanel;public int width=20;public int height=20;public int x;public int y;public int index=0;public Image[] images=new Image[] {Toolkit.getDefaultToolkit().getImage("Picture/BossBullet.png"),Toolkit.getDefaultToolkit().getImage("Picture/BossBullet1.png"),Toolkit.getDefaultToolkit().getImage("Picture/BossBullet2.png")};public BossBullet(MyPanel myPanel) {this.myPanel=myPanel;}public void drawSelf(Graphics g) {g.drawImage(this.images[index], x, y, width, height, null);if(this.myPanel.timer%1==0)y++;if(y>580)this.myPanel.bossBullets.remove(this);if(this.myPanel.timer%2==0) {index++;if(index==images.length)index=0;}if(y>BaseFrame.frameHeight)this.myPanel.bossBullets.remove(this);}}

三组件碰撞类

因为飞机大战中，重要利用的就是各种组件相碰撞而制作成的游戏，所以这部分肯定少不了。这里需要对各种组件进行判断，看他们是否相碰撞，判断的依据就是他们之间的距离是否小于最小距离。
碰撞类：

public class Crash {public MyPanel myPanel;Music music = new Music();public String enemy_bomb="Music/enemy_bomb.wav";public String hero_bomb="Music/hero_bomb.wav";public String boss_boom="Music/10804.wav";public Crash(MyPanel myPanel) {this.myPanel=myPanel;}//判断子弹和敌机碰撞public boolean Boom1(Bullet bullet,Enemy enemy) {int bulletx,bullety;int enemyx,enemyy;boolean crash=false;//子弹坐标bulletx=bullet.x+3;bullety=bullet.y+7;//敌机坐标enemyx=enemy.x+20;enemyy=enemy.y+12;if(Math.abs(enemyx-bulletx)<20&&Math.abs(bullety-enemyy)<12) {crash=true;//如果相撞返回真music.playMusic(enemy_bomb);}return crash;}//判断子弹击中boss机public boolean Boom5(Bullet bullet,Boss boss) {int bulletx,bullety;int bossx,bossy;boolean crash=false;//子弹坐标bulletx=bullet.x+4;bullety=bullet.y+9;//敌机坐标bossx=boss.x+50;bossy=boss.y+36;if(Math.abs(bulletx-bossx)<50&&Math.abs(bullety-bossy)<36&&this.myPanel.boss_flag==1) {crash=true;//如果相撞返回真music.playMusic(enemy_bomb);}return crash;}//飞机碰撞敌机public boolean Boom2(Enemy enemy,int x,int y) {int enemyx,enemyy;boolean crash=false;//敌机坐标enemyx=enemy.x+20;enemyy=enemy.y+12;//英雄机坐标x=x+40;y=y+36;//相撞条件if(Math.abs(x-enemyx)<50&&Math.abs(y-enemyy)<50) {crash=true;music.playMusic(hero_bomb);}return crash;}//英雄机被Boss的子弹击中public boolean Boom4(BossBullet bossBullet,int x,int y) {int bossbx,bossby;boolean crash=false;//敌机坐标bossbx=bossBullet.x+10;bossby=bossBullet.y+10;//英雄机坐标x=x+45;y=y+36;//相撞条件if(Math.abs(x-bossbx)<50&&Math.abs(y-bossby)<50) {crash=true;music.playMusic(hero_bomb);}return crash;}//飞机获取空投public boolean Boom3(Airdrop airdrop,int x,int y) {int airdropx,airdropy;boolean crash=false;//空投坐标airdropx=airdrop.x;airdropy=airdrop.y;//英雄机坐标x=x-30;y=y-30;//相撞条件if(airdropx>x+20&&y-airdropy<20&&airdropx<x+60) crash=true;return crash;}}

四线程类

这里主要控制游戏的进行，飞机大战中利用了线程去实现，从而使游戏的表现更好，能一致进行。
线程类：

import java.awt.*;
import javax.swing.*;
public class DrawableThread extends Thread{public MyPanel myPanel;public DrawableThread(MyPanel myPanel) {this.myPanel=myPanel;}public void run() {while(true) {this.myPanel.repaint();//重绘调用paintComponenttry {Thread.currentThread().sleep(1);}catch(InterruptedException e) {e.printStackTrace();}}}
}

五监听器类

这里主要使用监听器去实现用鼠标控制英雄机的移动，和用鼠标控制游戏的开始和结束。
控制英雄机的移动：

import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;
import java.awt.event.MouseMotionListener;
public class FrameMouseListener extends MouseMotionAdapter{public BaseFrame baseFrame;@Overridepublic void mouseMoved(MouseEvent e) {// TODO Auto-generated method stubthis.baseFrame.myPanel.player.x=e.getX()-this.baseFrame.myPanel.player.width/2;this.baseFrame.myPanel.player.y=e.getY()-this.baseFrame.myPanel.player.height/2;}}

控制游戏的开始和结束：

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;import javax.swing.JFrame;
public class FrameMouseClick extends MouseAdapter{public BaseFrame baseFrame;@Overridepublic void mouseClicked(MouseEvent e) {// TODO Auto-generated method stubif(this.baseFrame.myPanel.flag==2||this.baseFrame.myPanel.flag==3){this.baseFrame.dispose();//直接退出new BaseFrame();}this.baseFrame.myPanel.flag=1;}}

六音效媒体类

为了增加游戏的体验感和沉浸感，我给游戏添加了游戏背景音乐和子弹击中音效和英雄机死亡音效，效果不错。

import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;public class Music {void playMusic(String musicLocation){try{File musicPath = new File(musicLocation);if(musicPath.exists()){AudioInputStream audioInput = AudioSystem.getAudioInputStream(musicPath);Clip clip = AudioSystem.getClip();clip.open(audioInput);clip.start();clip.loop(0);}}catch(Exception ex){ex.printStackTrace();}}}
