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:文章来源:https://www.uudwc.com/A/DNLLW/

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。文章来源地址https://www.uudwc.com/A/DNLLW/
