好的，所以我在做一个 pacman 任务（在 bascialy pacman 和 ghosts 在屏幕上移动并且 pacman 从他们身上反弹之前发布过，但是当点击鼠标时，ghosts 会反弹他并改变为“害怕的图像”，并且尽我所能告诉我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最后的框架和边界代码移动到顶部时它们会显示但都在屏幕的一个点上没有移动. 有什么建议吗？

除非您帖子的格式已关闭，否则您的所有游戏循环逻辑现在似乎都在循环之外。请记住，Python 对缩进很敏感，因此所有代码都以：

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

不在循环内：

finished = False
while not finished:

你所有的绘图代码都是在游戏循环之后发生的，所以在当前的形式下，它只会被渲染一次，就在pygame.quit()被调用之前。
