Getting AI to do what I want

[cemason]

In my mod I have a sort of "holy city" that every civilization wants. Controlling it is worth many points.

Is there a way using AI_ calls in GameUtils python scripts to convince the AI that it's utmost and important goal is to go after this city?

I've tried the following but after simulating a whole game, the AI never builds ships, an army, sails to the city, and tries to take it. Maybe someone out there can suggest something?

                #HolyCity is the city all AI are after
		if not pPlayer.isHuman() and pGroup.getActivityType() == -1:
			# set activity
			pGroup.setActivityType(6) #ActivityType.ACTIVITY_MISSION)

			# push mission
			#MissionType.MISSION_MOVE_TO=0
		        #MissionType.MISSION_BEGIN_COMBAT=29
			#MissionAIType.MISSIONAI_ASSAULT=18
			pGroup.pushMission(0, 
                               HolyCity.getX(), HolyCity.getY(), 0,
                               False, False, 18, 
                               CyMap().sPlot(HolyCity.getX(),HolyCity.getY()),
                               pUnit)
			pGroup.pushMission(29, 
			                   -1, -1, 0,
                               True, False, 18, 
                               CyMap().sPlot(HolyCity.getX(),HolyCity.getY()),
                               pUnit)
