此代码的最后阶段是制作一个功能性自上而下的游戏，其目标是成为一种心理恐怖。到目前为止，游戏中的机制是与墙壁的碰撞，以及通过扩展，门，水平和角色的移动。
总的来说，我可以告诉任何人的是，这个错误与代码中不是全局和导入的所有内容有关（除非我错了，这对我来说更有意义。），并且它有一些东西给做与
A）代码行140
B）在'sprite.py''self.add(*group) (which is line 142 in the 'sprite.py' file)'下的特定行下引发错误
我可以推测的一点是，可能代码抛出一个无限循环，因为看着控制台在IDLE Shell中显示代码，或者pyscripter的消息部分（我用来编程这个），在程序终止之前无限期地迭代。除了无限循环之外，没有创建视觉效果，似乎没有任何事情发生。代码消息是'文件'C：\ Python33 \ lib \ site-packages \ pygame \ sprite.py“，第142行，添加self.add（* group）我不能肯定地说，你可能更好自己运行代码以查看可以收集的内容。
