== Custom AI personalities for AI-controlled custom empires ==

If you want your custom empire to be used as an AI opponent, you would probably like it to behave in "appropriate way" - for example custom Zerg or Tyranid empire should be extremely aggressive and unwilling of any diplomacy. You can make this happen in two ways.
First one, you simply create custom empire and hope it will get appropriate default AI personality assigned (in this case, Fanatical Purifiers or Hive Mind). Personalities of AI nations in Stellaris are assigned on the beginning of new game basing on certain combinations (and, to lesser extent, government or traits) of empires - you can check the weights in Stellaris->common->personalities->00_personalities.txt.

However much more reliable way, and often the only one, is to '''make a new personality for your custom empire. This is much easier task than it sounds.''' 00_personalities.txt file contains notes which explain what each line of code in this file means, so you can easily create your own AI personality just by changing few words and tweaking few numbers.
Example of such custom AI personality made for custom empire is

 xenomorph_hive = { 
        type = purifier          #these words seems mysterious but they are all explained in original file
        aggressiveness = 2.0
        trade_willingness = 0.0
        bravery = 1.0
        military_spending = 1.2
        colony_spending = 1.2	
        alliance_acceptance = -1000
        federation_acceptance = -1000
        threat_modifier = 0
        friction_modifier = 10
        behaviour = {
                conqueror = yes
                subjugator = no
                liberator = no
                opportunist = yes
                slaver = no
                uplifter = no
                purger = yes
                dominator = yes
                infiltrator = no
                robot_exploiter = yes
                robot_liberator = no
                migrator = no
         }
         allow = {
                has_country_flag = xenomorph
         }
         weight_modifier = {
                weight = 1000			
         }
 }

This way, AI xenomorphs will always get the personality "Xenomorph Hive", making them unable of diplomacy, aggressive and murderous, and no other AI empire will ever get it.
You can of course add the localisation of such custom personality too, so it will display when you encounter Xenomorphs in game - add something like that to your mod's localisation file:

 personality_xenomorph_hive:0 "Xenomorph Hive"
 personality_xenomorph_hive_desc:0 "Xenomorph Hive is a collective of terrifying predatory species. Diplomacy with them   is impossible, they wish to exterminate all other life they perceive as danger to them."
