我正在制作一个pacman游戏，而且我现在已经掌握了基础知识，但是在我们吃完所有的情况后，我无法让pac颗粒重新生成。目前我已经建立起来，在吃掉一粒pac颗粒后，它会从pacpellets列表中删除。当列表为空时，它会被重新填充，然后被告知将所有的pac颗粒重新绘制到屏幕上。虽然我已经检查了所有正确的功能和所有内容，但是我已经使用了打印语句进行了检查，但是pygame.draw.rect并没有工作，我无法弄清楚原因。

我会做这样的事情：定义一个创建精灵组的函数并用粒子精灵填充它，然后返回它并将它分配给main函数中的变量。当pellets组为空时，只需再次调用此函数并将新组分配给旧变量，粒子将再次出现。

如果您确定pygame.rect.draw不起作用，请尝试使用绘图功能，我使用它并且它可以工作。在这里查看有关绘图功能的更多信息
https://www.pygame.org/docs/ref/sprite.html#pygame.sprite.Group.draw
和一些示例代码
Displaying platforms using strings (Pygame)
我不太了解你的长列表，但你可以缩短它是否使用了字符串列表（也在示例代码中）。希望我能提供帮助。
