python - Pygame - 检测组中的碰撞时出错

Question

每次我运行我的代码时，我都会不断收到错误，而且我无法弄清楚原因。我还有一些脚本执行完全相同的工作，但 Sprite 不同。我正在尝试检测“门”和“玩家”之间的碰撞。这是错误:

Traceback (most recent call last): File "C:\Blood_Red\Pokemon_Blood_Red.py", line 225, in door_enter = pygame.sprite.spritecollide(door_group, player, False) File "C:\Users\Cameron\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pygame\sprite.py", line 1524, in spritecollide spritecollide = sprite.rect.colliderect AttributeError: 'Group' object has no attribute 'rect'

这是我的代码:

您在这一行中以错误的顺序将参数传递给 pygame.sprite.spritecollide:

door_enter = pygame.sprite.spritecollide(door_group, player, False)

应该是:

door_enter = pygame.sprite.spritecollide(player, door_group, False)

第一个参数必须是 pygame.sprite.Sprite，第二个参数必须是 pygame.sprite.Group。
