我正在尝试使用PyGame在Python中制作游戏，但是我收到了这个回溯：
Traceback (most recent call last):
File "C:\Users\usuario\Documents\abscorp\232\232.py", line 150, in
<module>
hits = pygame.sprite.groupcollide(drop, player, True, True)
File "C:\Python27\lib\site-packages\pygame\sprite.py", line 1536, in
groupcollide
c = SC(s, groupb, dokillb, collided)
File "C:\Python27\lib\site-packages\pygame\sprite.py", line 1500, in
spritecollide
for s in group.sprites():
AttributeError: 'Player' object has no attribute 'sprites'
有一些水滴应该从管道中随机掉落，但IDLE不断给我一个错误信息。我相信产生错误的部分如下：“pygame.sprite.groupcollide”。
完整代码附于下方。

错误消息显示它与groupcollide有问题所以在documentation 中检查它。
groupcollide（group1，group2，dokill1，dokill2，collided = None） - > Sprite_dict
找到在两组之间发生碰撞的所有精灵。
文档显示它需要两组 - 这意味着pygame.sprite.Group
但你使用的player是pygame.sprite.Sprite
检查Sprite和Group之间的碰撞
