我如何阻止我的游戏重新启动时，我的暂停播放我的game_loop函数在pygame

Question

所以，我正在pygame中制作一个简单的电子游戏，并且它非常接近完成。我正在制作暂停屏幕，但当我点击p(我选择的按钮)时，它暂停了，但当我点击继续时，它重新启动了游戏。我检查了代码，没有发现任何问题。然后，我去了这里的问题论坛，查找问题，我发现了一些东西，但他们不像我一样做代码，最重要的是，答案很难理解。暂停函数为paused()，取消暂停函数为，surprise, unpause()。你能查一下哪里出了问题吗?这是我的网址代码:

Answer 1

似乎您没有在pause()函数中取消暂停。

你应该添加这样的内容:

def paused():
    while pause:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            if event.type == pygame.K_p:
                unpause()

Answer 2

在我的代码中，我将取消暂停按钮函数设置为game_loop()而不是unpause()。所以每次我去取消暂停，我重新开始游戏循环!这是一个例子，你必须注意你的代码的每一部分，而不仅仅是函数出错。
