java实现飞机大战
用Java写个飞机大战游戏练习一下,实现可播放游戏背景音乐和游戏的基本功能
设计
1、准备好相应的图片和背景音乐(.wav文件);
2、直接看源码;
3、还有部分功能未实现。
源码
package forGame
加载游戏图片类
package forGame; import javax.imageio.ImageIO; import javax.swing.*; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; //游戏图片包装 public class ImageUtil { //图片大小 public static int WIDTH_BACK; public static int HEIGHT_BACK; public static int WIDTH_PLANE; public static int HEIGHT_PLANE; //图片 public static BufferedImage START; public static ImageIcon BUTTON; public static BufferedImage PLANE_1; public static BufferedImage PLANE_2; public static BufferedImage Bullet_1; public static BufferedImage Bullet_2; public static BufferedImage XIAO_PLANE; public static BufferedImage BOMB_PLANE1; public static BufferedImage BOMB_PLANE2; static { try { START = ImageIO.read(new File("src\\image\\背景2.png")); BUTTON = new ImageIcon("src\\image\\开始.png"); PLANE_1 = ImageIO.read(new File("src\\image\\飞机1.png")); PLANE_2 = ImageIO.read(new File("src\\image\\飞机2.png")); Bullet_1 = ImageIO.read(new File("src\\image\\导弹1.png")); Bullet_2 = ImageIO.read(new File("src\\image\\导弹2.png")); XIAO_PLANE = ImageIO.read(new File("src\\image\\小飞机.png")); BOMB_PLANE1 = ImageIO.read(new File("src\\image\\飞机爆炸1.png")); BOMB_PLANE2 = ImageIO.read(new File("src\\image\\飞机爆炸2.png")); } catch (IOException e) { e.printStackTrace(); } WIDTH_BACK = START.getWidth(); HEIGHT_BACK = START.getHeight(); WIDTH_PLANE = PLANE_1.getWidth(); HEIGHT_PLANE = PLANE_1.getHeight(); } }
播放游戏背景音乐类
package forGame; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.Clip; import java.io.File; //播放背景音乐(.wav文件) public class PlayMusic { private Clip clip; //需要传入要播放的文件位置的字符串 public void start(File file) { try { //创建相当于音乐播放器的对象 clip = AudioSystem.getClip(); //转成可播放的文件 AudioInputStream audioInput = AudioSystem.getAudioInputStream(file); //播放器打开这个文件 clip.open(audioInput); //clip.start();//只播放一次 //循环播放 clip.loop(Clip.LOOP_CONTINUOUSLY); } catch(Exception ex){ ex.printStackTrace(); } //死循环不让主程序结束(swing可不用) /* while(true){ } */ } //关闭音乐播放 public void exit(){ clip.close();//停止音乐播放,下次播放重新开始 } //停止音乐播放 public void stop(){ clip.stop();//停止音乐播放,下次播放继续播放 } }
package planeGame
接口
package planeGame; import java.awt.*; //绘制接口 public interface DrawMe { void drawMe(Graphics g); }
package planeGame; //分数接口 public interface Grade { int getGrade(); }
窗口父类
package planeGame; import forGame.ImageUtil; import forGame.PlayMusic; import javax.swing.*; import java.io.File; //窗口父类 public class MyJFrameFather extends JFrame{ protected int y1 = 0; protected int y2 = -830; protected PlayMusic playMusic = new PlayMusic(); public MyJFrameFather(String name){ super(name); setSize(ImageUtil.WIDTH_BACK, ImageUtil.HEIGHT_BACK); setLocationRelativeTo(null); setResizable(false); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); playMusic.start(new File("src\\music\\bgm.wav")); } }
开始界面

飞机父类(抽象类)
package planeGame; import java.awt.*; //飞机父类 public abstract class Plane implements DrawMe{ //飞机坐标 protected Point p = new Point(); //飞机是否活着 protected boolean isLive = true; //飞机移动速度 protected int speed; public Plane(int x,int y){ p.x = x; p.y = y; } //修改飞机坐标以重复使用 public abstract void setP(int x); //画自己 public abstract void drawMe(Graphics g); //移动 public abstract void move(); //获取飞机坐标 protected Point getP(){ return p; } //飞机发射子弹 public void playBullet(Bullet bullet){ //子弹状态为true bullet.setLive(); } //改变飞机状态 public void setLive(boolean aboolean){ isLive = aboolean; } //返回飞机状态 public boolean getIsLive(){ return isLive; } }
主飞机类
package planeGame; import forGame.ImageUtil; import java.awt.*; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; //主飞机 public class MainPlane extends Plane{ //移动方向 1;上 -1:下 2:右 -2:左 private int direction = 1; public MainPlane(int x, int y) { super(x, y); } @Override public void setP(int x) {} private boolean aBoolean = true;//绘制动态主飞机 @Override public void drawMe(Graphics g) { if(isLive){ if(aBoolean) { g.drawImage(ImageUtil.PLANE_1, p.x, p.y, null); aBoolean = false; } else { g.drawImage(ImageUtil.PLANE_2, p.x, p.y, null); aBoolean = true; } } else{ g.drawImage(ImageUtil.BOMB_PLANE1, p.x, p.y, null);//未绘制动态爆炸效果 } } @Override public void move() { if(direction == 1 && p.y > 30) p.move(p.x,p.y + speed); else if(direction == -1 && p.y < ImageUtil.HEIGHT_BACK - ImageUtil.HEIGHT_PLANE) p.move(p.x,p.y + speed); else if(direction == 2 && p.x < ImageUtil.WIDTH_BACK - ImageUtil.HEIGHT_PLANE) p.move(p.x + speed,p.y); if(direction == -2 && p.x > 0) p.move(p.x + speed,p.y); } //监听飞机移动 private KeyListener keyListener = new KeyAdapter() { @Override public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); //移动方向 1;上 -1:下 2:右 -2:左 //上 if(keyCode == KeyEvent.VK_UP){ direction = 1; speed = -20; move(); } //下 if(keyCode == KeyEvent.VK_DOWN){ direction = -1; speed = 20; move(); } //左 if(keyCode == KeyEvent.VK_LEFT){ direction = -2; speed = -32; move(); } //右 if(keyCode == KeyEvent.VK_RIGHT){ direction = 2; speed = 32; move(); } } }; //返回键盘监听器 public KeyListener getKeyListener(){ return keyListener; } //主飞机是否与敌机相撞 public void isBomb(Plane[] planes){ for(int i = 0;i < planes.length; i++) { if (planes[i].getIsLive()) { if(planes[i].getP().x > p.x && planes[i].getP().x < p.x + 128 && (p.y - planes[i].getP().y < 64)) { isLive = false; planes[i].setLive(false); } } } } }

创建主飞机、敌机、子弹类
