I needed a script to find the optimum soul gem in a player's inventory, in this example the highest level. (In an ideal world I'd just have the player click the desired soul gem, but alas due to soul gem's nature that'd just bring up the recharging screen)

So first off I tried doing it the clunky way: comparing base ID's. But then I realised that gems the player had charged didn't change their ID. So an empty soul gem fully charged would still have the base ID of an empty soul gem. The "precharged" gems were not used as replacements when a gem is charged they're merely for loot purposes. If I wanted to find the soul levels I'd have to scan all the player's gems.

So I came up with this neat little bit of coding:

	set iSoulLevel to 0	set iItems to GetNumItems	Label 1		set iItem to iItem + 1	if (iItem <= iItems) 		set rSoulGem to GetInventoryObject iItem		if (rSoulGem.IsSoulGem == 1)			set iSoulLevel to GetSoulLevel						if (iSoulLevel > iBestSoul)				set rBestGem to rSoulGem				set iBestSoul to iSoulLevel			endif			endif		GoTo 1	else		PrintToConsole "Found a level %.0f soul", iBestSoul	endif

Except that iBestSoul always returns zero, because GetInventoryObject gets the object's base version and not the actual inventory object itself and it's relevant properties. I've been scanning and scanning the OBSE documentation and CS but come up empty. How would I go about scanning through the individual *references* in someone's inventory in order to determine which soul gem to use?

there are no references in inventory
OBSE 19 (beta) introduces some functions that treat inventory items like pseudo references - check 19's docs
also search this forum for "soul gems" someone brought this issue recently

also I think GetInventoryObject starts count on 0 so you have to change the code above - check the wiki

Disregard my earlier statement (I'd been using the wrong function)

None of the past threads seemed to have a solution, but the new 0019 container iteration doodad worked:

	let rContainer := getSelf			foreach (rSoulGem <- rContainer)		if (rSoulGem.IsSoulGem == 1)			set iSoulLevel to rSoulGem.GetSoulLevel			PrintToConsole "Summon: Object has a level %.0f soul", iSoulLevel		endif	 		loop

Works as intended. Thanks for pointing out 0019 had what I was after =3

(The idea is a little minimod that let's a player use souls trapped in soul gems either straight, or in combination with some spare bones or reagents or a dead body to create undead minions the old fashioned way instead of conjuring them from the netherworld wholesale. Put the necro into necromancy)


Edit: Yup, everything working precisely as intended now. In case anyone is intrested, this is the little snip of code I'm using to drain the target soul gem and replace it, in case anyone wants to reverse engineer it for their own purposes. SetCurrentSoulLevel doesn't seem to work for existing entries, so the function sets up a "virtual" change, generates an altered copy from those changes and then deletes the original.

		let rContainer := getSelf			foreach (rRef <- rContainer)		if (iTargetGem > 0)			if (rRef.IsSoulGem == 1)						set iThisSoul to rRef.GetCurrentSoulLevel				set iThisGem to rRef.GetSoulGemCapacity				if ((iThisSoul == iTargetSoul) && (iThisGem == iTargetGem))					set iTargetGem to 0					rRef.SetCurrentSoulLevel 0					rRef.CopyIR rContainer					rRef.RemoveMeIR				endif			endif	 			endif	loop	set rRef to -1
