Question

我正在使用Python pygame制作游戏，并制作了一个移动的背景，作为玩家的跳跃精灵并产生了障碍。现在我正在研究玩家和障碍物之间的碰撞，并制定了一些代码但最终出现了错误：

      collided = pygame.sprite.spritecollide(player, obsticles, True)
    File "C:\Users\Kasutaja\AppData\Roaming\Python\Python27\site 
packages\pygame\sprite.py", line 1514, in spritecollide
        for s in group.sprites():
    AttributeError: 'Obsticles' object has no attribute 'sprites'

我不知道，为什么那个类不是精灵，以及如何使它成为精灵。我希望在修复此错误后，碰撞会起作用。

def generate_normal_dist_samples(lower_bound, upper_bound, size, scale=None): loc = (lower_bound + upper_bound)/2 if scale is None: scale = (upper_bound-lower_bound)/2 results = [] while len(results) < size: samples = numpy.random.normal(loc=loc, scale=scale, size=size-len(results)) results += [sample for sample in samples if lower_bound <= sample <= upper_bound] return results

您使用的是对象collided = pygame.sprite.spritecollide(player, obsticles, True)，而不是精灵组obsticles。所以要修复它，你可以这样做：

ob

Pygame sprite collision：对象没有属性'sprites'
