prerequisites for event choices

[DesertSnow]

I want to make an event, where certain parameters determine which of the event options are available to a player. Is this possible?

Also, can i create an event where the possibility that the AI will choose the A or the B choice is dependent on certain factors (e.g. a "loot province" event, where the culture/religion of the occupied province determines the choice?

Not really, you generally have to make separate events with different triggers - for example these ones for over/under a population mark:

province_event = 
          id = ####1

          trigger = {
          NOT = { population = 10 }
}
etc etc...

province_event = 
          id = ####2

          trigger = {
          population = 10
}
etc etc...

In general I would say just copy/paste the event, and change the id = #, trigger, maybe desc, and option to whatever you like.

Yes, the same types of modifiers that are used for MTTH can be used for ai_chance, like this:

option = { [I][COLOR=Red]###option 1###[/COLOR][/I]

ai_chance = {
         factor = 50
                     modifier = {
                           factor = 1.5 [I][COLOR=Red]###150% - 150% of 50% = 75###[/COLOR][/I]
                           has_province_flag = looted_province [I][COLOR=Red]###or "has_province_modifier = looted" or whatnot###[/COLOR][/I]
                    }
}

option = { [I][COLOR=Red]###option 2###[/COLOR][/I]

ai_chance = {
         factor = 50
                     modifier = {
                           factor = 0.5 [I][COLOR=Red]###50% - 50% of 50% = 25###[/COLOR][/I]
                           NOT = { has_province_flag = looted_province } [I][COLOR=Red]###or "has_province_modifier = looted" or whatnot###[/COLOR][/I]
                    }

Hope this helps.

Don't forget that by applying ai_chance to a character event, you can make an occurence more or less likely without the player being able to see the decision the AI is making.

@Battlecry: Do those modifiers also work on random and/or random_list?

It's not mentioned in any of the EU3 documentation, but I suppose it could be. Easy enough to test...just set an event with a simple trigger (ai = no, 1 day MTTH), set a modifier like tag = ___ (whatever country you choose) on the random_list and see if the percentages change. It'd be awfully useful if it did work.
