※ 참고
pygame.sprite.spritecollideany()
Simple test if a sprite intersects anything in a group.
● spritecollideany(sprite, group, collided = None) -> Sprite Collision with the returned sprite.
● spritecollideany(sprite, group, collided = None) -> None No collision
If the sprite collides with any single sprite in the group, a single sprite from the group is returned. On no collision None is returned.
If you don't need all the features of the pygame.sprite.spritecollide() function, this function will be a bit quicker.
The collided argument is a callback function used to calculate if two sprites are colliding. It should take two sprites as values and return a bool value indicating if they are colliding. If collided is not passed, then all sprites must have a "rect" value, which is a rectangle of the sprite area, which will be used to calculate the collision.
