pygame window 显示黑屏
pygame window showing blank screen
我在 pygame 中做了很多修改,但是每当我 运行 这个程序时,我得到的只是一个空白屏幕(没有错误)。我知道这不是我的代码的问题,因为我从互联网上复制了另一个人的程序,但它甚至没有用。我在 Mac os。大约 1 个月前,我编写了这段代码,当时它可以正常工作,但现在我得到的只是一个空白屏幕。我该如何解决这个问题?(我也查看了其他类似的问题并且 none 的 os 解决方案有效)
无论如何,这是我的代码(使用了带有 tim 教程的技术):

您的代码在主函数中有 win = pygame.display.set_mode((WINDOW_WIDTH,WINDOW_HEIGHT))
。我通常将 pygame.display.set_mode 放在主函数之外。你也没有添加pygame.init
。我认为这是问题所在。
我休息了几个月,认为我应该重新安装最新版本的 pygame。一旦我这样做了,我就在 atom 和 Jupyter notebook 上都试过了,但是 none 它们都工作了。我尝试使用常规 python IDE,结果出人意料地有效。
