项目结构分析

在这个游戏中，所有的物体都是飞行物所以有一个总的抽象类类:飞行物体类（FlyingObject）

飞行物的子级划分：奖励飞行物（*Prize），飞机（Plane），武器（Bullet）

飞机的子级划分：敌人飞机（enemy），英雄机（hero）

敌人的飞机又分普通敌人和特殊敌人，武器又分普通武器和特殊武器，英雄机又分a，b，c。。。等英雄机

话不多说上代码。。。。。。。

飞行物体类FlyingObject

        return result;
    }

}

英雄机（ZeroRedHero）这个名字是根据我找的素材图片取的。。。。。。。。

/**

 */
public class ZeroRedHero extends Plane{

    /**
     * 初始化零号机
     */
    public ZeroRedHero(){

        this.setLife(3); // 设置生命值
        this.setFlySpeed(999); // 设置飞行速度
        this.setAttackSpeed(5);// 设置攻击速度
        this.setFirepower(1); // 设置火力值 上限为3
        this.setBullet(new CommonBullet(true,"../img/bullet/bullet.png",3)); // 设置武器
        this.setX(PlayMain.GAME_WIDTH / 2 / this.getImgWidth() * this.getImgWidth());
        this.setY(PlayMain.GAME_HEIGHT - this.getImgHeight());
    }
}
