当我在 python 2.7 和 pygame 中编写一个基本的 UFO 游戏时，我遇到了一个错误，但是它没有出现在控制台中。发生的事情是:
- 我在编程
- 对代码做了一点改动
- 菜单屏幕运行良好，我去玩游戏了
- 然后它会不断重启。
- 我编辑了更多的代码，使其处于 while 循环中，直到它正确调用命令。
- 它仍然不会调用命令。

这是损坏的两段代码。 (我把类放在 def 的上面，这样你就知道那里是什么类了)
class UFO():

self.y = (height-self.iy)/2
self.DA = "Alive"
print Alive
class Game():

self.Player.New()
Place = self.Player.DOA()
if Place != "New":
self.TotalTime = 0
self.Background.New()
self.Bullits.Restart()
self.Orbs.Restart()
如果你在 IDLE 中使用代码，那么你会知道它甚至不会调用 self.Player.New() 因为 Shell 不会打印“Starting”或者给我一个错误让我把 print Alive，它只是不断循环while 循环。
对于代码的英里，:( 但希望它有所帮助，主要是因为如果没有其中的一些你将无法理解它。也感谢您花时间阅读并尝试回答这个问题。对于所有的语法和剥落，我们深表歉意错误，我不会拼写。
请您参考如下方法:
您的问题是您的 Game.New 方法中的 While True，我还发现了导致游戏无法运行的其他问题。
