新上手pygame，断断续续学习python也有一短时间了，心血来潮复刻一个小游戏（其实差的不少）。
界面就是这样：
游戏目标也很简单：四色方框来回碰撞移动，控制黑色方框躲避他们，得分是坚持多少的秒数。
贴代码，新手水平，可以打磨的地方还有很多

最有技巧的地方在碰撞检测，刚刚上手，还没看到pygame内部有没有碰撞检测的地方。所以就用黑色方块的四个角的坐标与其他的方块对比，如果控制的是圆形的话恐怕要算圆心距离了。暂时我也想不到其他的好办法。
timer()对象用来检测时间，time.clock()是一个全局的变量。不好控制，做定时器的话应该还有更好的方法。
时间关系，就先以上这些。
PS: 《python游戏 编程入门》这本书的错误不少，建议大家不要买这本书。
