退出pygame而不退出idle

这是我正在制作的文本冒险游戏的菜单屏幕代码。我想将其用作菜单屏幕，因此当您单击播放时，它将退出 pygame 并返回 python shell 运行游戏。但是，当我通过单击播放退出函数 evalOption() 时，它将打印错误：字体未初始化，就好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。这个程序最终会被导入到我的真实文本冒险模块中。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

任何帮助将不胜感激！

引发错误是因为您的代码在您调用 pygame.quit() 后尝试绘制到屏幕上。

代替

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

随便用

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

退出你的主循环。
