SSE Event to remove a spawned reference

[greyday01]

If a container is spawned by PlaceAtMe how can you get rid of it? An on Activate script attached to the container could be used, maybe with a RegisterForSingleUpdate as a timer. Is there any other ways to use a scripted event to disable and then delete the reference to get completely rid of it, preferably while not in sight of the player?

There are different ways you can do this, but all depends on what you are trying to accomplish (and how).

I'll add 2 ways to achieve it:

1) With 'RegisterForUpdate()'.

- The script lives inside the 'Base' container.

- We use a 15 sec update loop to not make it unnecessarily system pull heavy.

Actor Player

 

AUTO STATE WaitingPlayer

EVENT OnActivate(ObjectReference akActionRef)

      Player = Game.GetPlayer()

   If ( akActionRef == Player )

        RegisterForUpdate(15.0)

        GoToState("Inactive")

EndIf

ENDEVENT

ENDSTATE

 

STATE Inactive

ENDSTATE

 

EVENT OnUpdate()

   If ( Self.GetParentCell() != Player.GetParentCell() )

        UnregisterForUpdate()

        Self.Disable()

        Self.Delete()

EndIf

ENDEVENT

2) With 'OnCellDetach()'

- The script lives inside the 'Base' container.

- This is a simpler version and way less system pull heavy, but the events OnCellDetach() - OnCellAttach() - OnAttachedToCell() - OnDetachedFromCell() will not fire under certain conditions.

AUTO STATE WaitingPlayer

EVENT OnActivate(ObjectReference akActionRef)

   If ( akActionRef == Game.GetPlayer() )

        GoToState("Removing")

EndIf

ENDEVENT

ENDSTATE

 

STATE Removing

EVENT OnCellDetach()

      Self.DIsable()

      Self.Delete()

ENDEVENT

ENDSTATE

Thank you. I'm not quite sure what "Detached" means. Does it mean the container is detached from the parent cell by being moved to a different cell, or does it mean the player is detached from the parent cell by leaving it? Or does it mean the player moved far enough from the parent cell that that cell is no longer loaded so everything in that cell is detached? What is being detached from what? Papyrus terms don't sometimes match what the English word means and it gets confusing.

[maxarturo]

It's logical to be confused, in general the wiki is not much of a help regarding in depth explanations and possible issues with Papyrus flaws.

'OnCellDetach()'

When the player enters a cell (any cell), all items in there are 'Loaded'.

- Now, when the player leaves that cell all objects / actors can run an 'OnCellDetach()' event, because the player does no longer exists in that cell with the object carring the script.

- Now, this function can also run on the object / actor (and if the object has in it the script function), once the object moves from that cell to another from where the player and the object / actor commonly shared (they lived in that same cell).

I hope I'm clear enough and I'm not confusing any further.

[greyday01]

Yes. You are very helpful as always. I think OnCellDetach might work though I can't really control how close to a cell border the thing is spawned at and that might be a problem. Maybe go for a timer instead because the player probably won't be standing around watching it. I really wish that there was an easy way to get the ref ID for things spawned.

"I really wish that there was an easy way to get the ref ID for things spawned."

You actually can:

EVENT SomeEvent....
           ObjectReference SpawnContainerREF = Self.PlaceAtMe(MyContainer, 1)

           SOME FUNCTIONS.....

           SpawnContainerREF.Disable()
           SpawnContainerREF.Delete()
ENDEVENT

EVENT SomeEvent....
           Actor SpawnActorREF = Self.PlaceActorAtMe(MyActor)

           SOME FUNCTIONS.....

           SpawnActorREF.Kill()
           SpawnActorREF.SetCriticalStage(3)
           SpawnActorREF.SetCriticalStage(4)
ENDEVENT

 

* Stores the reference's ID for later use

* I Use 'Self' assuming that the script is living inside the object / whatever is using the function to spawn the reference.

That is really great. It should be added as an example in the creationkit.com scripting reference of PlaceAtMe. I'm sure others have needed that same fragment of script.

This has nothing to do with Papyrus, it's just programming stuff that you learn by studying.
