I need to detect when the player applies a poison, but the events don't work as intuitive as I hoped. I have a script attached to the player which receives Actor and ObjectReference events, but I can't seem to find an event that covers all cases.

I've tested the following events in-game:

OnSpellCast()
Only gets called for Potions, not for Poisons (Which are essentially just Potions with the IsHostile() property)

OnObjectEquipped()
Also only gets called for Potions, not Poisons

OnMagicEffectApply()
Since poison effects are applied to the weapon, this also only gets called for Potions

OnItemRemoved()
Gets called two times, once when the confirmation dialog is shown and another time when the poison is applied, so I need to detect when I receive this event two times. However since I have no way of knowing if the player answered "no" on the confirmation, receiving the event two times could just mean the player cancelled the poison two times.

Any help would be greatly appreciated. If you can suggest any other event I could look at that may be triggered when a poison is applied, please tell me.

I haven't done this. so I don't know whether it works, but "Poisons Used" is a stat that gets tracked. So you could perhaps call

RegisterForTrackedStatsEvent() 

and then

Event OnTrackedStatsEvent(string asStatFilter, int aiStatValue)    if (asStatFilter == "Poisons Used")       ; etc

Thank you for the reply. I have found a similar solution inspired by the following thread: http://www.gamesas.com/topic/1371503-info-onspellcast/

I now save the value of Poisons Used before I start tracking the OnItemRemoved() events and then check if the Poisons Used has increased. It looks like this:

Event OnItemRemoved(Form akBaseItem, int aiItemCount, ObjectReference akItemReference, ObjectReference akDestContainer)  int stat = Game.QueryStat("Poisons Used")  if(stat > previousStat)	; the poison was actually used  endifEndEvent
