Adding New Building Type -- Need Help

[unmerged(133356)]

I've noticed that several cultures get added types of buildings to provide various benefits, unit types, etc.

For example, parts of western Europe get a building type that produces more heavy cav, as opposed to the handful you get from the standard Stables. Or the building that produces horse archers for some of the steppes cultures.

Using the above as an example, and using Poland as an example since it doesn't appear to have access to any, how would I add a building type that would only be available to provices with Polish culture, and would provide a small number of knights, or horse archers, or whatever?


I can see, looking at the file buildings.txt, where those buildings are, and some of how they work. I'm going to be trying to make it work in the meantime, but any help would be appreciated. I'm also looking at the stickied thread on how to set up a mod.

Thanks.

You can adjust whatever numbers you want from here, but the following should work - it'd activate for anyone with Polish culture in the same way. The requirements to build this is that your ruler is Polish, and (I believe; though could be wrong) the AI will build this only if Polish and Christian. If anyone more knowledgeable catches something wrong here in my characterisation of what the building does, or in the building I wrote up here (built upon the Squire List building for the German, Frankish, and Occitan cultures), let me know.

As to where you copy/paste this...just tag it on at the end of the Castle section, between the Russian section and the start of the Citys (# City) in buildings.txt

ca_culture_polish_1 = {
		potential = {
			FROM = {
				OR = {
					culture = polish
				}
			}

		light_cavalry = 10
		horse_archers = 15
		ai_creation_factor = 101
		
		start = {
			AND = {
				FROM = { religion_group = christian }
				year = 1125
				has_building = ca_stable_1
			}
		}
	}
	ca_culture_polish_2 = {
		potential = {
			FROM = {
				OR = {
					culture = polish

	}

start = {} defines what holdings have the building from the start. AI will build according the ai_creation_factor, AFAIK.

 

[unmerged(133356)]

Should those culture lines that list off all the Frankish, German, etc, be replaced by one line for Polish in each upgrade?

 

[Baneslave]

Surely yes.

 

[Geredis]

Yeah; sorry I missed those in the list - I didn't mean to leave them in.

 

[unmerged(133356)]

It works, now I just need to figure out how to make it show a name in the game... it shows up as "ca_culture_polish_1" on the build list.

 

[Geredis]

Need to add a localization. It's not that hard really and quite self explanatory if you look in the localisation files.

 

[unmerged(133356)]

Thanks.

I've done a lot with savegame editing on Paradox games, but not much on modding until CKII.


EDIT: found the lines in #3, and it worked without a hitch.

Someday I'll figure out how to make this into a mod so that I don't have to keep swapping out files if I want to play MP with someone...

Someday I'll figure out how to make this into a mod so that I don't have to keep swapping out files if I want to play MP with someone...

Make a folder in the mod folder.
Make a file of the same name, ending with .mod.
In that file, put this:

name = "Name" # name of your mod, shown in launcher
path = "mod/name" # location of your mod files 
user_dir = "Name" # optional. creates a sub directory where settings/map cache/savegames etc can be safely written for your mod and not get mixed up

Only bother with the last one if the mod is save-game incompatible.

Now put all files you've modded in the mod-folder you made, and preserve the original structure (E.G., anything you've modded in "common" goes in a "common" folder in your mod-folder). You'll now be able to enable the mod through the launcher.

Going to try doing this, since the last patch evidently overwrote my changes, despite the buildings.txt file not being on the list of altered files for the patch.


EDIT: it worked.

Next question -- does a modded file that only adds lines need to have the entire contents of the basic file, or will CKII combine the contents when it loads, allowing only the additional lines to be in the file for the mod?

Bump -- see question above. Thanks.
