碰撞不起作用子弹对暴徒

Question

我试过很多方法让我的子弹和我的暴徒相撞，但都没用。子弹直接穿过人群。我也尝试了spritecollide和groupcollide代码，但都失败了。也许我把代码放错了行或者放错了地方。我还想把子弹和暴徒从名单上删除。你知道吗

如果有人能在这件事上帮助我，我将不胜感激。我花了很多时间研究这个解决方案，但还没有找到。看了很多youtubers，做了同样的事情，但就是不起作用。你知道吗

Answer 1

当我运行这个程序时，我得到一个不同的错误，一个由这行引起的AttributeError。这是因为mobs列表应该是pygame.sprite.Group。你知道吗

mobs = pygame.sprite.Group()
for x in range(0,10):
    mob = Mob(Monster)
    mobs.add(mob)

在我修改了这部分代码之后，它就正常工作了。你知道吗
