Event to call when player takes object?

[TangerineDog]

What's the event to use when I want a script attached to an object to run as soon as the player takes said object?

[cdcooley]

Event OnContainerChanged(ObjectReference akNewContainer, ObjectReference akOldContainer)
    if akNewContainer && akNewcontainer = Game.GetPlayer()
        ; picked up by player
    endif
EndEvent

If there are many copies of the item or it is something the player will put down and pick up again many times you should use a PlayerRef property.

Actor Property PlayerRef Auto

Event OnContainerChanged(ObjectReference akNewContainer, ObjectReference akOldContainer)
    if akNewContainer == PlayerRef
        ; picked up by player
    endif
EndEvent
