Question

我在这里没有涉及到我的设置，因为那只是基本信息，而我在此代码中遇到的问题是线程。当我涉及我的线程T4和T5时，游戏只会停滞不前，我不知道为什么，因为我认为线程就像是一个附带代码，在主代码上没有效果。希望您能在这里帮助我谢谢！

我不得不禁用我的一些代码，因为我不允许发布这么多的代码，但是问题不在于线程

Answer 1

在Bossfight中，您有以下内容：

sp

那是一个“忙循环”；解释器将基本上停在那里，但会连续检查while boss.rect.x > 70: pass。将boss.rect.x > 70换成短暂的睡眠，以免消耗过多的CPU。

firebosslaser也有类似的问题：如果pass为False，它将永远循环。在该循环后添加bossfightstart，您应该会没事。

当我运行太多线程并且不知道为什么时，我的游戏崩溃
