前言

我们已经基本完成了书上的所有操作，共用了14天学习，今天我们进行整理，将完整代码整理出来，供大家学习，也为今后我自己调阅。

---

一、心得体会

经过这段时间的学习，可以说浅显了解了pygame这个模块的一些函数使用，确实针对游戏的设计方面提供了很便利的支持。初步掌握了这些方法，我们可以很方便的作出一些其他的游戏。比如扫雷游戏，通过鼠标点击判断，再比如说贪食蛇，主要核心应该是碰撞的监测。至于纸牌或是其他的游戏目前还没有想好。

 除了接触到一些新的函数，还学习了面对对象编程的方法，虽然不在公司上班，只是个人的小打小闹，但是先进的编程理念学起来肯定没有错。同时还感受到了规范的命名规则，对于我来说有点困难，因为英语不行，所以这个命名会大大降低我的编写速度，在调用函数时，要反复的看单词怎么写，太浪费时间了。

二、整体分析

这次我们总共写了9个类，其实还是有规律的，不同的对象各自建一个类，比如说小花猫、小老鼠和子弹。然后需要修改的参数放在一个类，事件监听放在一个类等等，现在将所有的类代码整理如下：

总结

后面我准备将游戏在改一改，时代在进步，游戏画面我是无能为力，但是游戏机制可以改一改，这种老土的游戏机制我实在玩不下去，不符合我们现在玩的飞机大战，将小花猫的行动轨迹改一改，可以全屏移动，然后将小老鼠也改成不规则的，而不是集体向下 向右，如果有可能的话，改成躲避类，最后小老鼠也可以放子弹。
