Contrary to popular rumor, I’m not the designer of the Jadwiga campaign!
But if you want an AI faction to respond to taunts, you need to put (taunt-detected any-human <taunt #>) in the conditions of a defrule in your script. The effects after the => in the defrule can be set to change the AI faction’s behavior in response to the taunt.
If the taunt is supposed to activate a trigger, then the list of effects in your defrule should include (set-signal <signal #>), for which you can use the AI Signal option in the list of Conditions in the Scenario Editor to implement the effect.
If you want an AI faction to respond to receiving a tribute, then the defrule’s condition should include (players-tribute-memory <player #> ). For example, for Michael of Zahumlje’s tribute request in Tomislav 5, I used (players-tribute-memory 1 gold greater-or-equal 1500), then wrote (set-signal 18) in the list of effects; an in-mission trigger would then respond to AI Signal 18, causing him to ally with the player.
