Hey guys, I am quite the noob when it comes to Papyrus (hopefully this will change soon ) so this could be easy...
I have some pillars that the player needs to jump on to get over a gap and between these pillars I have put in some icicles, at this point I suppose they are stalagmites. If possible I would like to have the player killed if they miss a pillar and fall into the icicles.

Thoughts/tips on how to go about doing this? Thanks for any info.

Just put a trigger by the spikes so that it makes sense that if the player enters it that they would die.

Then attach a script to the trigger:

Event OnTriggerEnter(ObjectReference akActionRef)   akActionRef.Kill()EndEvent

That would kill whoever entered the trigger. You could add an 'If akActionRef == Game.GetPlayer()' to only kill the player. (Not enemies or followers, etc)

Hmmm, when saving the script I get an error saying "Kill is not a function or does not exist".

Oops. Kill() is a function that must be called on an actor, not an obj ref. This can be easily fixed by casting the property. Change the middle line to:

(akActionRef as Actor).Kill()

There we go, works perfectly and it's so simple. Thanks a lot for the help, one step closer to completion.
