说明：  飞机大战 首先对这个游戏分析,在屏幕上的物体都是飞行物,我们可以把建一个类,让其他飞行物继承这个类.游戏中应有英雄机(也就是自己控制的飞机)、敌人。而敌人应该分为打死给分的飞机（就是普通飞机），另一种就是打死有奖励的敌人。他们都应该是飞行物的子类，我们也可以为普通飞机和给奖励的敌人设一个接口让他们去实现接口，这样有利于以后的扩展，我在这里给的简化版的飞机大战，主要是为了让大家了解面向对象。(First of all, analyze the game. The objects on the screen are flying objects. We can build a class and let other flying objects inherit this class. There should be hero planes (i.e., planes controlled by ourselves) and enemies in the game. And the enemy should be divided into killing the aircraft (that is, ordinary aircraft), the other is to kill the enemy with reward. They should be subclasses of flying objects. We can also set an interface for ordinary aircraft and reward enemies to implement the interface, which is conducive to future expansion. The simplified version of aircraft War I gave here is mainly to let you understand object-oriented.)
