Python Pygame简单的程序来测试显示是否冻结

有没有比我更有经验的人能告诉我为什么下面的代码会冻结（挂起）窗口？它应该做的就是显示一个红色屏幕，并在窗口名中更新其FPS。谢谢！：）

在游戏类中，您将

runGame

声明在

\uuuu init\uuuu

函数之外，并且不将

self.runGame

用于减速。您还仅在首次创建游戏对象时更新FPS，因此它将保持相同的值

通过以下方式解决此问题：

在初始化代码内移动

runGame

减速，并使其

self.runGame

添加一个更新

self.fps

的调用。我在

draw

函数下添加了它

因此，您的结束代码应该如下所示（注释包含在我更改内容的地方）：

我做了你的编辑，谢谢你，这种方式更加一致，但窗口对我来说仍然冻结。因为我必须强制退出，它根本不允许我移动窗口。这可能是因为你没有任何事件处理，但我不是100%同意，嗯，可能就是这样。我要拍一些进去看看！。。。就这样。谢谢Deachex！让我知道它是如何进行的，我在这里帮助更新了一些事件代码的OP，现在可以工作了！谢谢你的帮助
