pygame学习笔记（6）——一个超级简单的游戏
<div id="cnblogs_post_body">转载请注明：@小五义http://www.cnblogs.com/xiaowuyi学了这么长时间的Pygame，一直想写个游戏实战一下。看起来很简单的游戏，写其来怎么这么难。最初想写个俄罗斯方块，想了很长时间如何实现，想来想去，也没写出来，于是干脆下载别人的代码来读。后来，要想写一个帮助记忆的挖宝箱的游戏，结果也没完成。唯一完成了就是下面这个小人接金币的游戏，超级简单，通过左右键控制小人移动去接空中下来的金币，接住金币得5分，接不住游戏结束，金币速度会随着level的关数而越来越快。完成这段代码后，我依然觉得这段代码写得很差，确实也是自己对pygame只是掌握了皮毛，对surface、sprite这些理解的还不透彻。这里把代码写出来，有时间的大牛们可以帮助指点一下，让我也有所提高。
