碰撞不起作用 Bullet vs Mob

Question

我已经尝试了很多方法让我的子弹与我的生物相撞，但它不起作用。子弹直接穿过暴民。我也尝试了 spritecollide 和 groupcollide 代码，但它们都失败了。也许我把我的代码放在错误的行或错误的地方。我还希望从列表中删除子弹和暴民。

如果有人可以帮助我解决这个问题，我将不胜感激。我花了很多时间研究解决方案，但我还没有找到任何解决方案。看了很多youtubers，做了同样的事情，但就是行不通。

Answer 1

当我运行程序时，我得到了一个不同的错误，一个 AttributeError 是由这一行 hits = pygame.sprite.groupcollide(bullet_list, mobs, True, True) 引起的。发生这种情况是因为 mobs 列表应该是 pygame.sprite.Group.

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

我更改了这部分代码后，它工作正常。
