[LE] most efficient way to detect when a set of items is picked up

[irswat]

Say I have 50 unique items and when anyone of these items are found I want to flag them as found. I assume I would use an OnItemAdded event and use some type of inventory filter, but what is the most efficient way to do this? I don't want the script running constantly, and I don't want the script wasting time detecting anything except these 50 items. Suggestions?

Another option I was considering was a small script using OnItemRemoved and then attaching it to the containers that the items are in. Is this the best way?

At first glance the only two ways to do this effectively would be to set up a quest then use either a global variable or register forupdate papyrus scripts attached to the items. Thats just my guess though. Prolly attach them to 50 different stages in the quest and just have the items register the update to the quest through script on itemadded then a getitemcount script like u mentioned. This is just a guess though dont take my advice to heart. Edited July 15, 2017 by XN0X0neX

Is it only the player picking these things up you're concerned about? E.g. if one of these unique items is a weapon and an NPC grabs it, you don't want to bother? And that you don't care if the player then drops it and picks it up again?

 

 

My solution would be a quest alias on the player, with an inventory filter that updates whenever one of the items is picked up, thereby removing it from future consideration. There's a few ways to implement that. I'd try this one:

 

1. Because the CK doesn't like Form as a property, pass the stuff in with a FormList. OnInit, add an inventory filter based on that. That should guarantee that only the items you're interested in fire the event. Then change the script state to a listening one.

2. Create an OnItemAdded event in the listening state. Do a sanity check to make sure the added form is in fact in the FormList, via HasForm. If it is, remove the inventory filter for that item and increment a counter.

3. If that counter is the same size (or greater, in case of oddities!) as the size of the FormList, clear the alias.

thanks, I did throw all the items into a formlist and added an inventoryeventfilter with the form list oninit. I will flip a switch and remove the form from the form list. It's a treasure hunt so you only need to find the item once. These items are being displayed in a dynamic book/checklist which also contains clues.

You can't remove editor-added forms from a formlist, only script-added ones. That's why I used a counter.

 

If you want to drive a book/checklist, you can create a second, empty formlist (or an array, but formlists tend to work better for passing information to various CK systems) and add the found forms to it as they're processed.

In a moment of clarity last night I decided against removing items from the formlist when they are found, but I can't remember why lol
