Constructed buildings of a castle holding

Buildings are fairly simple to mod.

Building definitions are located in common\buildings\ folder.

Structure

potential = { religion = catholic }

desc = shipyard_desc

add_number_to_name = no

ca_steppe_barracks_1 = {
	replaces = ca_barracks_1
}

trigger = { TECH_CASTLE_CONSTRUCTION = 0 }

is_active_trigger = {
 location = {
  OR = {
   port = yes
   borders_major_river = yes
   borders_lake = yes
  }
 }
}

port = yes

	prerequisites = { ca_wall_1 }
}

ai_creation_factor = 95

ai_feudal_modifier = -10

ai_republic_modifier = 5

extra_tech_building_start = 0.4

Example

Here is an example from common\buildings\00_Castle.txt:

ca_keep_6 = {
	desc = ca_keep_1_desc
	trigger = { TECH_FORTIFICATIONS_CONSTRUCTION = 8 }
	upgrades_from = ca_keep_5
	gold_cost = 500
	build_time = 2190 #6y
	levy_size = 0.3
	garrison_size = 0.2
	ai_creation_factor = 97
		
	extra_tech_building_start = 0.2
}

Localization

• <building_name>: name of the building
• <building_name>_desc: description of the building
• <building_name>_<religion_group>: overridden name by religion group (at least for temple building)

Adding a new building

So lets assume you want to add a new building to the game. This guide will give basic instruction on how to create a basic working building. There are more polished and professional ways to attack this task, but they will all build upon the basic file structure and placement included below.

There are several decisions that you have to make in order to create a building that will work correctly. In what type of settlement will the building be located, castle, city, or temple? What type of restrictions will be placed on where the building can be created? What will be the bonuses or traits that this building grants?

First locate the "buildings" folder inside the CK2 file structure. Usually it is something like: C:\Program Files\Steam\SteamApps\common\buildings. Once you have located the "buildings" folder you will need to add an entry to the one of these files that corresponds with the type of building you wish to add. For this example I am going to add a simple statue to my castle that will provide some nice bonuses, so I will choose the 00_castle.txt file.

It is highly recommended that you use Notepad++ to edit the file and make a backup of this file before you make any changes.

Under the "castle = {" heading I am just going to copy the formatting of the first entry making minor changes to create my own building. My favorite starting location is Moray in Scotland, so I will restrict the building to only working in that province. I want the building to always be available for me to build, with modest costs, and some nice bonuses for my troops and income. It will look something like this:

castle = {
	ca_statue = {
		desc = ca_statue_desc
		potential = {
			OR = {
				province_id = 40 #Moray
			}
		}
		trigger = { always = yes }
		build_cost = 150
		build_time = 91
		knights = 50
		levy_size = 0.5
		tax_income = 5
	}
}

There are tons of different triggers and traits that can be added to buildings to make them unique and powerful! It may be worthwhile just looking at the other entries to learn how to personalize your building. This building will give my lord 50 heavy infantry, a 50% larger levy, and 5 as income!

Once these lines have been added to the 00_castle.txt file, the description tags need to be created in the localisation directory, it should be in the same folder where you found the "common" folder.

Using Notepad++ copy one of the .csv files and rename it for your own building. Open the file and delete all lines except for the top line (which only serves as a template and is not actually necessary). Follow the format that it explicitly outlines in the template on the top line, making sure not to miss any punctuation marks! If desired you can add these translations, just type the French description you wish to appear in place of the "FRENCH" on the appropriate line. I don't play the game in other languages, so I didn't add any translations. Mine looks something like this:

#CODE;ENGLISH;FRENCH;GERMAN;;SPANISH;;;;;;;;;x
ca_statue;Heroic Statue;FRENCH;GERMAN;;SPANISH;;;;;;;;;x
ca_statue_desc;This heroic statue stands as a testament for the deeds of the great men who came before and that all men can achieve greatness.;FRENCH;GERMAN;;SPANISH;;;;;;;;;x

After completing these steps you should have a Statue you can build in Moray.

Changing restrictions on holdings

It is not possible to add new Holding types, but you can define the conditions for being allowed to build each holding type. Definitions for those restrictions are located in the common\holding_types\ folder. The only thing supported within a holding is trigger, which defines when it can be built. ROOT is the province, FROM is the builder. Some hardcoded restrictions also apply and cannot be overriden. For example, if you wanted to restrict building temples only to theocratic characters:

temple = {
	trigger = {
		FROM = {
			is_theocracy = yes
		}
	}
}
