python - Pygame，pygame_menu - 启动后关闭和视频系统未初始化错误

问题描述

我正在尝试制作西蒙游戏。我是编程初学者。我在菜单第一次启动程序时遇到问题。当我点击播放和子菜单中的另一个播放时，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，但它立即关闭而没有错误消息。

所以它仍然存在：
第一次开始 -> 开始并出现关闭错误。
第二次开始 - >关闭窗口没有错误。
我检查了一些帖子我检查了一些帖子，但它没有工作。

对不起，我的英语不好。感谢您的提示

解决方案

当您关闭窗口然后main()运行game.quit()​​which close access to video 但接下来它会返回到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。这使得问题

您可以exit()在 `game.quit() 之后使用退出程序。

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