SKSE alternative[edit source]

You basically have to make your own version of this function with SKSE, if you want to avoid certain references, but especially the player because it's so easy for it to be the return value.

Actor Function GetClosestActorFromRef(ObjectReference akCenter) Global
	;/ Returns the closest actor to akCenter. akCenter is excluded from the search.
          *1. Check if there is more than 128 actors or only akCenter.
          *2. Iterate through all actors found and record their distances to the player.
          *3. Find the smallest distance from the player and return the actor.
          *4. Valid types for actors: 43 or 62
        /;
		
	ObjectReference[] kRefs = new ObjectReference[128]
	Float[] fDistances = new Float[128]
	Cell kCell = akCenter.GetParentCell()
	Int CellRefs = kCell.GetNumRefs(43) 
	Float fLowestValue = 1000000.0
	Int i
		
	if (CellRefs >= 129 || CellRefs == 1)
		return none
	endif
		
	while i < CellRefs
		ObjectReference kActors = kCell.GetNthRef(i, 43)
		if kActors != akCenter
			kRefs[i] = kActors
			fDistances[i] = kActors.GetDistance(akCenter)
			
			Float fCurrentValue = fDistances[i]
		        if fCurrentValue <= fLowestValue
				fLowestValue = fCurrentValue
			endif
		endif
		i += 1
	endWhile
		
	Int refIndex = fDistances.Find(fLowestValue)
		
	return kRefs[refIndex] as Actor
EndFunction

How fast this function returns, depends on how many actors are in the cell. --Rasikko (talk) 2018-01-02T02:58:34 (EST)
