Pygame、pygame_menu - 启动后关闭且视频系统未初始化错误

如何解决Pygame、pygame_menu - 启动后关闭且视频系统未初始化错误

我正在尝试制作 Simon 游戏。我是编程初学者。 我在菜单启动时第一次启动程序时遇到问题。当我点击子菜单中的播放和另一个播放时，它会启动主循环并且游戏正常运行。 当我关闭窗口时，它给了我一个错误：

pygame.display.flip() 错误：视频系统未初始化

当我第二次启动程序时，窗口将启动，但它立即关闭，没有错误消息。

所以它仍然存在：
第一次启动 -> 启动并关闭错误。
第二次启动 -> 无错误关闭窗口。
我检查了一些帖子 我检查了一些帖子，但没有用。

抱歉我的英语不好。 并感谢您的提示

解决方法

当您关闭窗口时，main() 运行 game.quit() 关闭对视频的访问但接下来它返回到 mainMenu 仍然运行 mainloop() 以绘制菜单并且它仍然尝试访问视频显示菜单。这会导致问题

您可以在`game.quit() 之后使用exit() 退出程序。

        if event.type == game.QUIT:
           game.quit() 
           exit()
