Talk:Find (Procedure)

Is there a way to limit the object list to only what the subject has LOS on? —The preceding unsigned comment was added by Jbezorg (talk • contribs) 2013-02-17T23:36:59‎

I can't say for sure, since I don't know anything about ObjectLists at all, and know almost nothing about scripting. But if they are Arrays (Papyrus), you could maybe, after populating the array with find, do something like...

	; Using the player here, but use whatever actor you like.
	Actor Property PlayerREF Auto
	PlayerREF.Find(PlayerREF.GetCurrentLocation(), yourTarget, yourObjectList, false, false)

	; Remove items from the object list that aren't found. WARNING, may be slow.
	Int iElement = yourObjectList.Length
	While iElement
		iElement -= 1
		If (!PlayerREF.HasLOS(yourObjectList[iElement]))
			; Remove the element.
			yourObjectList[iElement] = none
		Endif
	EndWhile

If they are formlists instead of arrays, then something like this instead:

	; Using the player here, but use whatever actor you like.
	Actor Property PlayerREF Auto
	PlayerREF.Find(PlayerREF.GetCurrentLocation(), yourTarget, yourObjectList, false, false)

	; Remove items from the object list that aren't found. WARNING, may be slow.
	Int iElement = yourObjectList.GetSize()
	While iElement
		iElement -= 1
		Ref rObject = yourObjectList.getAt(iElement)
		If (!PlayerREF.HasLOS(rObject))
			; Remove the element.
			yourObjectList.RemoveAddedForm(rObject)
		Endif
	EndWhile

Something like that: I know probably less than you about scripting, but this may take you in vaguely the right direction maybe. Catwheezle (talk) 2013-02-28T15:23:10 (EST)
