[LE] Add item from a list of notes and not get them more than once issue.

[littleork]

So I am not sure if there is a way to do this but maybe someone knows.

 

I have a chest that spawn 5 notes. Now I have about 13 notes to choose from and I want the 5 notes to be chosen from that list. I know how to add an item from a formlist/leveledlist/array etc but the problem I am running into is that it might give me the same item multiple time.

 

Is there a way to ask for 5 items from a list and make it so it will not give me a second copy of the item, a bit like making the notes unique? I really want it to be random

Use a FormList, and RemoveAddedForm, perhaps?

 

Have an empty Form List, and on start-up, have a Quest populate it with all of the possible notes, then grab 1 note from the list, and add it to the chest. Not 100% sure on the Script, but something like :

 

 

Function SelectANote()
MyFormList.AddForm(Note001)
;Do for all 13 Notes
 
NoteCount = 0
While ( NoteCount < 5 )
   FormListLength = MyFormList.GetSize()
   FormListLength = ( FormListLength - 1 )
   WhichNote = Utility.RandomInt(0, FormListLength)
   MyNote = MyFormList.GetAt(WhichNote) as Book
   MyChest.AddItem(MyNote, 1, 1)
   MyFormList.RemoveAddedForm(MyNote)
   NoteCount = ( NoteCount + 1 )
EndWhile
EndFunction

 

Depending how you want it to do, you could have it fire on the Chest being Activated, so it would populate it the first time it's opened.

Hmmm I will try that! Thanks.

Maybe the following script is what you want to have? It's a bit different to the approach of CDM_

 

FiveNotesAddToChestScript

 

Scriptname FiveNotesAddToChestScript extends ObjectReference
{written by ReDragon 2017} ; we assume this script is attached to the chest
