本文实例为大家分享了java抖音飞机大作战的具体代码，供大家参考，具体内容如下

Airplane.java

package zmf.game.shoot;
import java.util.Random;

/**
 * @author jcf
 * @Description: Airplane----敌机既是飞行物
 * @date 2018-03-28 11:17:16

public class Airplane extends FlyingObject implements Enemy{
 /** 敌机走步的步数 **/
 private int speed = 2;
 public Airplane(){
 image = ShootGame.airplane;
 width = image.getWidth();
 height = image.getHeight();
 Random rand = new Random();
 x = rand.nextInt(ShootGame.WIDTH - this.width);
 //y:负的敌机的高
 y = -this.height;

 }

 @Override
 public int getScore(){
 return 5;
 }

 @Override
 public void step(){
 y += speed;
 }

 /**
 * 是否越界
 * @return
 */
 @Override
 public boolean outOfBounds(){
 //敌机的y坐标大于窗口的高
 return this.y > ShootGame.HEIGHT;

 }

}

FlyingObject.java

package zmf.game.shoot;
import java.awt.image.BufferedImage;

/**

 /** 宽 **/
 protected int width;
 /** 高 **/
 protected int height;
 /** x坐标 **/
 protected int x;
 /** y坐标 **/
 protected int y;

 /**
 * 飞行物走步
 */
 public abstract void step();

 /**

 /**
