前一段在数据分析中突然感觉到了一阵阵的空虚寂寞冷，所以我决定小小放松一下，于是萌生出了写一个小游戏的想法。所以在pygame中摸索了2天，终于完成了无聊的飞机大战代码。之前从来没写过游戏，所以感觉还蛮好玩儿的。在此分享出来，有兴趣的可以拿去玩玩儿咯！！
游戏完成的主要功能：
①用户飞机由用户控制；敌机自动移动。
②用户飞机由用户按空格键开火；敌机自动开火。
③击毁敌机会使敌机子弹速度逐渐增加，以达到逐渐增加游戏困难的目的。
④加入飞机坠毁的五毛特效。
⑤加入bonus功能，吃到bonus可以增加用户子弹速度，并减缓敌机子弹速度。
具体代码如下：

友情提示：想要代码完美成功运行，要添加对应敌机，用户飞机等图片到相应路径并可能需要修改对应参数。
总体总结：
①我采用的是面向对象的设计方法，创建了多个类，其中还有几个基类让其他类继承以达到减少代码量的目的。
②游戏整体算法采用的都是pygame中的基本操作，因为只是无聊消遣，所以我并没有太深的去探究pygame。
③在处理用户连续的不抬起按键时遇到了一些小问题，采用KEYUP与KEYDOWN结合可以解决这个小问题。
④在敌机摧毁时，如何消除敌机与敌机已经发出的子弹是个小难点。我采用的方法是当敌机被摧毁后，该敌机最后一颗子弹消失 后，再创建出一架新的敌机。
⑤bonus包的下落轨迹我采用随机函数产生随机数来决定，并不是让它直线下落以稍稍增加捡包的难度。
飞机大战基本就是这些内容啦。第一次写游戏，还是值得纪念一下的！！！
