这是我正在制作的文字冒险游戏菜单屏幕的代码。我想将它用作菜单屏幕，所以当你点击播放时它将退出pygame并返回到python shell来运行游戏。但是，当我通过单击play退出函数evalOption（）时，它将打印错误：字体未初始化，就像程序仍在尝试运行一样。有谁知道如何解决这个问题，以便我可以退出pygame，但仍然在python中运行一个模块。该程序最终将导入我的真实文本冒险模块。如果需要，这里是珊瑚礁背景的链接：https://www.google.com/search?q=coral+reef&espv=2&biw=1440&bih=799&source=lnms&tbm=isch&sa=X&ved=0ahUKEwix_OmD7s_JAhXGWD4KHXW-CrsQ_AUIBigB#imgrc=_dFX3xqK97FGNM%3A

非常感谢任何帮助！

引发错误是因为您的代码在调用pygame.quit()后尝试绘制到屏幕。

而不是

if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_x:
        pygame.quit()
        quit()

只需使用

if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_x:
        return

退出你的主循环。

在不退出闲置的情况下退出pygame
