[LE] Walking ref/actor checks? Simple right?

[SamHe11]

I'm trying to find the nearest actor to the player in a given radius with a script. According to the wiki, an example of PlayerRef.FindClosestActor(0.0, 0.0, 0.0, 100.0) would return the player as the closest actor since the player is an actor. How would I work in conditions to exclude certain actors that are returned with this function? Such as actors that are: not the player, not a follower of the player, etc....

 

Thanks.
