我被活活的逼成了pygame小白

前天闲来无事，刚好群里有人问谁会做pygame，老惯例，先把牛逼吹出去，拍胸脯说没问题，然后当晚赶紧开始刺激的学习pygame之旅。

学了两天也把项目搞定了，感觉我亏了，代码量不小，也头秃。
pygame这个引擎我感觉是有点out了，很少有人真正做点好东西，这个时代本来2d游戏就快被淘汰了，可选择的游戏开发引擎那么多，为啥非要想不开用pygame啊，只有一种可能性，那就是用来锻炼一下编程思维。。。这个目的确实也达到了。
中间处理了一坨又一坨的难点，每个都得去网上一顿搜，感觉网上pygame可能也不火，资源都很一般般。
想起来的知识点简单罗列一下：
整个游戏流程
素材缩放
时间处理
游戏编程思维（面向对象）
pygame种的timer
碰撞处理（这个到现在还是迷糊，分为矩形圆形和mask）

把代码整上吧，万一以后心血来潮还想用pygame做个界面啥的，兴许用得上。。。

写了三百多行。。。
