The method I'm currently using to check if the player has changed cells is this:

I have a quest script running that updates periodically. On update it checks the players current cell with GetParentCell and checks that against a saved variable that stores the last update check's GetParentCell. (variable only gets set if the current cell is found to be different)

My question is this: Is there a better way to do this? Requiring a background script for this seems lame.

Why isn't there a OnCellChange event?

The wiki lists two (maybe useful?) events but offers absolutely no useful information on their use...http://www.creationkit.com/OnDetachedFromCell_-_ObjectReference and http://www.creationkit.com/OnAttachedToCell_-_ObjectReference.

I made a simple script to try to test them but neither fire.

Event OnAttachedToCell()    Debug.MessageBox("Cell Attached?")EndEventEvent OnDetachedFromCell()    Debug.MessageBox("Cell Detached?")EndEvent

http://www.creationkit.com/OnLocationChange_-_Actor will work on a Player alias

There's http://www.creationkit.com/OnLocationChange_-_Actor, but I realize that's not the same thing. http://www.creationkit.com/OnCellLoad_-_ObjectReference will fire when entering a cell that was not loaded into memory. So it will fire if you first enter the cell, and if you move a couple cells away then come back.

Both events are in a script running the player, of course.

what is the difference between locations and cells? I'm really only interested in cell changes that require load screens, so interiors -> exteriors and vice versa, and fast travel

Edit: From my 5 minutes of testing, I think that should do the trick ;P. Thanks guys.

That doesn't work because the player is always in an attached cell.

I believe OnLocationChange won't work either, because it only fires when a reference moves in or out of a Location object.

Edit: nvm Took to long to type.

So that would work if, for instance, an object reference moved into the players cell from an unloaded cell?

Curious about this too. What event can you use to run stuff when a load screen occurs?

OnLocationChange works but not specifically on load screens. It fires when you change cells in the over world as well.

I slapped it on a magic effect and gave it to the player in an ability and ran around riverwood for a few minutes. It seems to do what I was looking for.
