How to change the factions' units?

[Mister S]

It's not that hard, at least for people who know about modding, but I just don't have a clue on how to do this.

I want Pontus to have Seleucid troops. It might be not even possible, but I just want to try. I have already placed elephants in Pontus' main region, so that's not a problem.
I have searched in the ExRM folder, but I just can't find the part where is described which factions use which troops.

Where to find this, and how to change it?

You'll need to add Pontus to the ownership line of the relevant units in export_descr_units.txt, a Pontic texture and sprite to the relevant units in descr_model_battle.txt (just copy/paste the Seleucid one and then change the name...make sure there's not already a Pontus line, though), and then change the EDB to allow recruitment: http://forums.totalwar.org/vb/showthread.php?t=50439

Oh, and you'll also need to copy the relevant unit and unit_info cards into the Pontus folder in the UI section. I always forget that.

type camel
skeleton fs_camel
scale 1.0
indiv_range 40
texture numidia, ExRM/data/RTR/models_unit/textures/numidia__camel.tga
texture seleucid, ExRM/data/RTR/models_unit/textures/seleucid__camel.tga
texture merc, ExRM/data/RTR/models_unit/textures/merc__camel.tga
model_flexi data/models_unit/mount_camel_high.cas, 15
model_flexi data/models_unit/mount_camel_med.cas, 30
model_flexi data/models_unit/mount_camel_low.cas, 60
model_flexi data/models_unit/mount_camel_lowest.cas, max
model_sprite 100.0, ExRM/data/RTR/sprites/camel_sprite.spr
model_sprite numidia, 100.0, ExRM/data/RTR/sprites/numidia_camel_sprite.spr
model_sprite seleucid, 100.0, ExRM/data/RTR/sprites/seleucid_camel_sprite.spr




So I should add

texture pontus, ExRM/data/RTR/models_unit/textures/seleucid__camel.tga
and
model_sprite pontus, 100.0, ExRM/data/RTR/sprites/seleucid_camel_sprite.spr

or can I put
texture seleucid, pontus, ExRM/data/RTR/models_unit/textures/seleucid__camel.tga
model_sprite seleucid, pontus, 100.0, ExRM/data/RTR/sprites/seleucid_camel_sprite.spr


EDIT:
nvm I did it already

It depends on whether (Option 1) you want Pontus to have Selucid Units or (Option 2) Pontus to have the same unit as the Selucids.

Option 2 is harder to code and is where Quin is advising you on the process.

Option 1, Find the export_descr_building (EDB) in your exrm data folder.
Find the auxilia building tree for Pontus

will look something like this (I have cut it down a bit as well


;;;;;;;;; #10 ----------- Pontos Barracks -----------
building barracks_pontus
{
levels auxilia_phase1 auxilia_phase2 auxilia_phase3 muster_field militia_barracks city_barracks army_barracks
- These are the levels available to this tree
{
auxilia_phase1 requires factions { pontus, } and building_present_min_level base_government eastern1
- name of first building, and its requirements in order to build ie Pontus and base government eastern 1 (Note the code name may not be the name that appears on screen)
{
capability
{
law_bonus bonus 2 requires factions { pontus, }
- This is what the building provides
}
construction 4
cost 500
settlement_min village
upgrades
{
auxilia_phase2
- What can be built next
}
}
auxilia_phase2 requires factions { pontus, }
{
capability
{
recruit "aor keltoi spearmen" 1 requires factions { pontus, } and hidden_resource aor_gaul
- This is the unit that can be recruited and the requirements need to be able to recruit it. In this case the region must contain the hidden resource aor_gaul
trade_base_income_bonus bonus 2 requires factions { pontus, }
law_bonus bonus 2 requires factions { pontus, }
}
construction 4
cost 700
settlement_min town
upgrades
{


Ive added my notes in colour to make them stand out.

Simply find the unit name from the selucid barracks system and
insert the lines into the Pontus barracks tree, replace { selucid, }
with { pontus, } for the recruitment requirement.

This is the easiest way to do it, but not necessarily the best way

[Mister S]

Thanks! That made it perfectly clear. But I wanted option 2, so here's what I did:

1. the things Quinn told me
2. in descr_buildings (or so), I copied the seleucid buildings into the Pontus buildings part, but changed all the {seleucid,} to {pontus}

The game runs perfectly now. Once again, Thanks to both of you for your help!

You are now officially a modder.

[Mister S]

Well - there is one more thing.
When I zoom out too far, the units disappear, but this only happens with some units.
What to do about this?

[Clearchus of Sparta]

That is something to do with sprites I believe, and I have absolutely no idea how to fix that.
Sorry.

Look for a guy called Mcantu in the RTR forums, he may well be able to help you

[Quinn Inuit]

I agree that it's likely a sprite issue. Check and make sure those units have sprites defined for Pontus.
