好吧所以我做了一个pacman任务(在bascialy pacman之前发布,鬼魂在屏幕上移动而pacman从他们身上反弹,但是当鼠标被点击时鬼魂反弹并改为“害怕的图像”并尽我所能告诉我已经解决了我的本地错误等。但是现在我的代码似乎根本没有显示任何精灵。当我将框架和边界代码移动到顶部时它们会显示但是所有在屏幕的一个点上都没有移动请问有什么建议吗?

除非您的帖子格式化已关闭,否则您的所有游戏循环逻辑现在都在循环之外。 请记住,Python对缩进很敏感,所以所有代码都以:

if pacman_boundary.left < 0 or pacman_boundary.right > WIDTH:

不在循环内:

finished = False
while not finished:

所有的绘图代码都是在游戏循环后发生的,因此在当前形式下,它只会被渲染一次,就在pygame.quit()之前。
