I am trying to upgrade ammo lists using a script. Using AddItemToLeveledList works just fine and the ammo lists are updated as expected.

What I would like to do next is create a test condition to prevent that code section from running a second time should the script be run again. And that is where I am running into a wall. I cannot find a method to check if a leveled lists contains a entry for another leveled list.

Here is my current code running in a gamemode block of a quest script. It compiles but does not function. Any ideas?

Set rListAmmo to LootAmmoBullets100 IF (ListGetFormIndex rListAmmo xCalxLootAmmo) == -1	AddItemToLeveledList LootAmmoBullets100 xCalxLootAmmo 0 10 1EndIF

And what's the problem with a standard DoOnce var?

Users have an uncanny ability to find new and creative ways to screw things up in ways modders can never anticipate. I am trying to create a self-repair script that goes through the various environmental changes the mod makes, and repairs any that are not set up properly for one reason or another.

If xCalXLootAmmo is a formlist, I think you'd need to step through it one entry at a time via listgetnthform and the LABEL/GOTO commands rather than trying to check for the whole thing at once.

xCalXLootAmmo is a compound leveled list containing other leveled lists. Leveled lists are handled differently from form lists which is my problem.

Do the FOSE list commands read a leveled list entry or do they specify the calculated results of leveled lists?

I think the FOSE List* commands are for formlists and not for leveled lists.

You could try if the following stage function works

; (Index 1) Is element  in list?; Local Varsshort ishort sizeref inputListref elementref currentElement; Read & Clear Inputset inputList to ListUtil.inputListset element to ListUtil.elementset ListUtil.inputList to 0set ListUtil.element to 0set ListUtil.found to 0set i to 0set size to (listGetCount inputList)label 1if i < size	set currentElement to listGetNthForm inputList i	if currentElement == element		set ListUtil.found to 1		return	endif		set i to i + 1	goto 1endif

Called via

set ListUtil.inputList to LootAmmoBullets100 set ListUtil.element to xCalxLootAmmosetStage ListUtil 1set found to ListUtil.foundif found == 0	AddItemToLeveledList LootAmmoBullets100 xCalxLootAmmo 0 10 1endif

But i dont think this will work.

Anyway, have you tried whether its even possible to add the same item twice? I think for formlists it isnt.

Formlists are one dimensional so they only retain a single instance of an object. I don't bother testing when updating to repair lists, but leveled lists have quantity so sequential adds seem to stack.

I guess I'll admit defeat and use a global variable as an indicator.

Thanks, not knowing that could really have screwed me up while making the compatibility patch for the FWE and the next release of Powered Power Armor - I was going to have fitted power armors break down into unfitted components to reduce the total number of broken sets of power armor I'd need to create, but that would have required having some broken sets show up more than once in the formlists I'm using to keep track of it all (I'm treating 3 formlists of equal length and specific order as a 2 dimensional array).
