Python Time.Sleep（）正在冻结我的pygame窗口并冻结我的函数

所以我遇到了一个大问题，5个小时以来我一直在研究这个问题，没有取得任何进展，这就是为什么我现在要问这个问题。在底部你可以看到代码，在那里我得到了我的问题。 所以它的基本功能是：它打开一个pygame窗口，有3个按钮：一个是开始，一个是停止，一个是退出

当你按下“开始”按钮时，一个循环应该运行，它每x秒播放一次声音，直到你按下“停止”按钮。 问题是，time.sleep（）确实冻结了整个窗口。是的，我做了很多研究，但我没有为自己得出结论。。。我是python的初学者，我做了大约两周。这也是我在这个社区的第一篇帖子，很抱歉，如果这篇帖子不一样的话！：p

我想要的是，当Tonemaker循环运行时，pygame窗口保持活动状态，您可以单击其他按钮

如果你需要更多的信息，尽管问吧！ 谢谢你的帮助！我真的很感激每一个答案，因为我现在真的被卡住了

tonerepeats = distance / frequence

看看你是否能从下面的代码片段中得到一些启发。 我不是pygame的开发者。但我相信这个概念，它应该按照下面提到的思路进行编码

import threading
import time

class SoundThread(threading.Thread):
    def __init__(self):
        self.quit = False
        self.event = threading.Event()  # Whenever this event is set, play sound
        self.event.clear()  # By default no sound should be played
        threading.Thread.__init__(self)

    def run(self):
        while not self.quit:
            eventSet = self.event.wait(timeout=1)
            if not eventSet:
                print("Skipping playing the sound")
                continue

            if self.quit:
                break
            # Play sound over here
            print("Play the sound")
            time.sleep(1)

    def begin(self):
        self.event.set()

    def halt(self):
        self.event.clear()

    def quit(self):
        self.quit = True


obj = SoundThread()
obj.start() # Launches a separate thread which can be controlled, based upon calls to begin, halt, and quit


# And add the below to wherever you have the action handlers.
if action == "start": obj.begin()
elif action== "stop": obj.halt()
elif action== "quit": obj.quit()

下面是一种方法，它结合了您已有的主循环。它检查循环中每个迭代的时间。如果经过足够的时间，它将调用

Tonemaker（）

函数。（省略了不相关的代码）

你需要创建一个单独的线程来触发声音的开启和关闭。。现在，

Tonemaker

正在主线程中运行。现在，您可以使用它触发另一个单独的线程来处理噪声生成，而不是永远阻止Tonemaker。好的。我已经试过用线做某事了。。但它并没有真正起作用。我怎么做一个单独的线程来做这个？我认为你不需要一个单独的线程。在未崩溃时，您已经有一个常量循环：…。只需检查该循环中的当前时间，并在1秒后调用该函数。重复。过一会儿让我分享一些示例代码。。不是专门针对pygame的，只是为了帮助你理解这个概念……好的。听起来不错。你到底是什么意思。那么我该如何检查当前时间呢？但是你必须根据自己的需要调整它。。我不认为你能用它straighaway是的。所以我现在实现了你的代码行，并更改了所有链接，它成功了，谢谢！！！这叫什么？你在那里用的是什么？？我想学习如何使用它。例如，我不知道self.event.set（）到底做了什么。这是线程的一部分吗？哇！恭喜你让它工作了。。您应该阅读互斥、事件、锁和信号量等概念。这里我们使用了事件的概念，这是一种线程安全的方式来设置标志。也可以阻止那个事件。如果你能对我的答案投赞成票，我将不胜感激，因为它对你有用！谢谢。试过这种方法，也奏效了！谢谢大家的帮助
