I have a script attached to an NPC. How do I perform an action based off the player starting a dialog with that NPC. Something like ondialog would seem appropriate (but doesn't exist). How do you do this?

You can simply use OnActivate:

if ( OnActivate == 1 )	Activate	; Do something else.endif

Or, you can introduce a short variable that gets set to a specific value in the NPC's unique high level greeting (from dialog). You can use the results box of the greeting to perform script tasks too.

Thank you for the feedback.
