Script: Check if the player's inventory changed

[NoCashNoExp]

I want to make a script that tracks the stack count of a specific item type in the player's inventory. Is there anyway to check if the player's inventory changed or even better if a specific item was added/removed?

Yes. Do you know how to make quests, aliases and attach scripts to them ?

Yes, as SKK50 said you can make a new quest, start game enabled, and put a reference alias on it that points at the player. Then use the OnItemAdded and OnItemRemoved events: Something like this

 

Scriptname MyPlayerReferenceAliasScript extends ReferenceAlias  

Form Property SomeItem Auto 

Event OnInit()
    AddInventoryEventFilter(SomeItem) 
    Int CurrentAmount = Self.GetActorRef().GetItemCount(SomeItem)
    Debug.Notification("Current amount is " + CurrentAmount)
EndEvent 

Event OnItemAdded(Form akBaseItem, Int aiItemCount, ObjectReference akItemReference, ObjectReference akSourceContainer)
    Int CurrentAmount = Self.GetActorRef().GetItemCount(SomeItem)
    Debug.Notification("Current amount is " + CurrentAmount)
EndEvent
   
Event OnItemRemoved(Form akBaseItem, Int aiItemCount, ObjectReference akItemReference, ObjectReference akDestContainer)    
    Int CurrentAmount = Self.GetActorRef().GetItemCount(SomeItem)
    Debug.Notification("Current amount is " + CurrentAmount)
EndEvent

Thank you both for your replies, I will test your code momentarily. I understand how to create quests and attach scripts but I didn't quite understand aliases. I will read aliases on the wiki again. This is the way I originally did it but for some reason it didn't work:

Scriptname testScript extends Quest


Actor Property pPlayerRef Auto Const Mandatory


Event OnInit()
Debug.Notification("Script Init")
RegisterForRemoteEvent(pPlayerRef, "OnItemAdded")
EndEvent


Event ObjectReference.OnItemAdded(ObjectReference origin, Form akBaseItem, Int aiItemCount, ObjectReference akItemReference, ObjectReference akDestContainer)
Debug.Notification("Item Added")
EndEvent

 

Edit: I managed to setup a player alias and tested your code and it works perfectly. Thanks again.
