我用python编写了一个用于大学项目的迷你游戏。它处于早期阶段，但是我在运行时遇到问题。当我运行.py文件时，出现一个黑色窗口。当我按下“ X”按钮关闭窗口时，只有这样我的背景才会显示一秒钟，然后窗口关闭。简而言之，我的游戏仅在我关闭窗口时运行。

谢谢大家。我为不需要的大代码感到抱歉，但是我真的不知道出了什么问题。
我编写代码，而不是“ while”，但是：在while循环中放置命令并使代码正确运行后，“ player”移动非常缓慢，“ dot to dot”移动。之前，“玩家”的举动非常正常和顺利。

除了walls = [....]语法错误之外，基本上该问题是主循环。
最大的问题是，由于缩进错误，while not done循环的尾部不包括最后两个代码块。 if player.rect.x > 900 and player.rect.y < 100:行之后的所有代码都不是循环的一部分，因为它向左缩进了1级。纠正此问题基本上可以解决所有问题。

我也将pygame.quit()行移到了程序的结尾。
