我正在尝试在碰撞组中找到某个精灵。在这种情况下,我的代码会检查每个平台,以查看播放器是否在触摸它。如果玩家触摸平台,则我希望玩家的底部y成为平台的(玩家正在触摸的)顶部y。我不知道如何获取某个平台并编辑该平台的属性。我将如何编辑我的代码以使其正常工作?

答案 0 :(得分:3)
hits
是碰撞的平台精灵的列表,因此您可以使用for
循环对其进行迭代,并将object.rect.bottom
设置为platform.rect.top
。
hits = pygame.sprite.spritecollide(object, allPlatforms, False)
for platform in hits:
object.vy = 0
object.rect.bottom = platform.rect.top
