敵飛機

import java.util.Random; 
 
 敵飛機: 是飛行物，也是敵人
 
public class Airplane extends FlyingObject implements Enemy {
 private int speed = 3; //移動步驟
 
 /** 初始化數據 */
 public Airplane(){
  this.image = ShootGame.airplane;
  width = image.getWidth();
  height = image.getHeight();
  y = -height;   
  Random rand = new Random();
  x = rand.nextInt(ShootGame.WIDTH - width);
 }
 
 /** 獲取分數 */
 @Override
 public int getScore() { 
  return 5;
 }
 
 /** //越界處理 */
 @Override
 public  boolean outOfBounds() { 
  return y>ShootGame.HEIGHT;
 }
 
 /** 移動 */
 @Override
 public void step() { 
  y += speed;
 }
 
}

分數獎勵

/** 
 * 獎勵 
 */
public interface Award { 
 int DOUBLE_FIRE = 0; //雙倍火力 
 int LIFE = 1; //1條命 
 /** 獲得獎勵類型(上面的0或1) */
 int getType(); 
}

蜜蜂

import java.util.Random; 
 
/** 蜜蜂 */
public class Bee extends FlyingObject implements Award{ 
 private int xSpeed = 1; //x坐標移動速度 
 private int ySpeed = 2; //y坐標移動速度 
 private int awardType; //獎勵類型 
 
 /** 初始化數據 */
 public Bee(){ 
  this.image = ShootGame.bee; 
  width = image.getWidth(); 
  height = image.getHeight(); 
  y = -height; 
  Random rand = new Random(); 
  x = rand.nextInt(ShootGame.WIDTH - width); 
  awardType = rand.nextInt(2); //初始化時給獎勵 
 } 
 
 /** 獲得獎勵類型 */
 public int getType(){ 
  return awardType; 
 } 
 
 /** 越界處理 */
 @Override
 public boolean outOfBounds() { 
  return y>ShootGame.HEIGHT; 
 } 
 
 /** 移動，可斜著飛 */
 @Override
 public void step() {  
  x += xSpeed; 
  y += ySpeed; 
  if(x > ShootGame.WIDTH-width){ 
   xSpeed = -1; 
  } 
  if(x < 0){ 
   xSpeed = 1; 
  } 
 } 
}

子彈類：是飛行物體

/** 
 * 子彈類:是飛行物 
 */
public class Bullet extends FlyingObject { 
 private int speed = 3; //移動的速度 
 
 /** 初始化數據 */
 public Bullet(int x,int y){ 
  this.x = x; 
  this.y = y; 
  this.image = ShootGame.bullet; 
 } 
 
 /** 移動 */
 @Override
 public void step(){  
  y-=speed; 
 } 
 
 /** 越界處理 */
 @Override
 public boolean outOfBounds() { 
  return y<-height; 
 } 
 
}
