python - 你如何隔离敌人的精灵，让它们在进入新房间时消失？
问题描述
我尝试了几种方法，例如在 room1 类中对敌人进行编码，但似乎没有任何效果，当我进入其他房间时，它要么根本没有产生预期的精灵，要么精灵产生但没有消失（除非我与它相撞）。这是我的代码，任何帮助都将不胜感激！
旁注，我也尝试为每个房间应用不同的背景，但也没有任何运气。需要做些什么来实现它？

解决方案
我认为您的意思是要从房间类的enemy_sprites 组中永久删除敌人的精灵。例如，从房间 1 self.enemy_sprites.add(Enemy("Judas.png"))，. 如果您想删除它，您可以执行相同的操作，但更改.add()为.remove(). 因此，只需键入self.enemy_sprites.remove(Enemy("Judas.png"))您只能在您所在的类也继承 Room 类的属性时执行此操作。
希望有帮助！:)
