AI personality modding template

[Wizzington]

Since I've been making an AI personality for a Blorg mod, and was asked about modding personalities, I thought I'd post a template for the benefit of the modders that want to plan out their own AI personalities, similar to how Johan posted the namelist templates.

Below you will find the Blorg 'Fanatical Befrienders' personality from the mod and the 'Peaceful Traders' personality from base game:

##### Types:
# honorbound -> Cares about honor and martial prowess above all else
# capitalist -> Cares about trade and material profit above all else
# hegemon -> Cares about the superiority of their own empire above all else
# ideologue -> Cares about combating opposing ethoses above all else
# isolationist -> Cares about maintaining their isolation from other empires above all else
# federation_builder -> Cares about bringing different species together in a federation above all else
# propagator -> Cares about the propagation of its species above all else
# purifier -> Cares about purifying the galaxy of other species above all else
# explorer -> Cares about exploring the galaxy and making scientific/spiritual discoveries above all else

##### Behaviours:
# conqueror -> Will they conquer planets from other empires?
# subjugator -> Will they vassalise other empires?
# liberator -> Will they liberate conquered empires?
# opportunist -> Are they more likely to attack someone already embroiled in war?
# uplifter -> Will they uplift and enlighten other species?
# infiltrator -> Will they infiltrate primitives?
# dominator -> Will they invade primitives?
# slaver -> Will they enslave pops?
# purger -> Will they purge alien pops?
# robot_exploiter -> Will they use robots for menial labor?
# robot_liberator -> Will they give rights to robots?
# migrator -> Will they want to migrate to other empires?

##### Modifiers:
# aggressiveness -> Chance of declaring wars
# trade_willingness -> At 1.0 willingness they will accept a deal that is equally good for both sides
# bravery -> Affects the chance that they will pick rivals & war targets of similar strength instead of picking on the weak
# military_spending -> Affects mineral & energy budget that goes to navies and armies
# colony_spending -> Affects mineral & energy budget that goes to new colonies

##### Diplomacy:
# alliance_acceptance -> Added directly to chance of accepting an alliance
# federation_acceptance -> Added directly to chance of accepting to form/join a federation

# NOTE: Weight is additive!

            factor = 1
            has_election_type = oligarchy
        }      
    }
}

Names are done in the format:

personality_fanatic_befrienders:0 "Fanatical Befrienders"
personality_fanatic_befrienders_desc:0 "Fanatical Befrienders are highly friendly but deeply lonely individuals. They will attempt to make friends by any means necessary."

You can play Ironman with mods but can't get achievements.

Since I noticed

NOT = { is_country_type = fallen_empire }

Is in there, does that mean we can create our own Fallen Empire types?

Yeah.

 

[Wizzington]

How easy would it be to mod in what makes Fallen Empires cranky?

Not hard at all, it's all controlled through script.

 

[Wizzington]

I presume Fallen Empires' personalities just have most of their behaviors set to "no" and lowered willingness to do anything... and then for their specific quirk/awaken triggers, the events will just check AI personality, e.g. type = keepers_of_knowledge?

Pretty much.
