I am trying to add new factions: Chaos factions, all Space Marine Chapters...
I actually started with the Emperors Children, with only one unit so far: the Noise Marines.
I am also currently meddling with the Skirmish Generator script to have them on random maps.
But to stay on topic with current post, here I was trying to see if the new unit and new faction just works in the Editor.
I added that to SIDES.txt: (local campaign file)
[SpaceWolves]
UICOLOUR 5d7084
NATION 0
[Goffs]
UICOLOUR c20000
NATION 1
[EmperorsChildren]
UICOLOUR 502da7
NATION 2
.. and a unit to squads.csv (local campaign file)
.. and a new army to ArmyList.txt ( named WARHOSTLUCIUS ), which uses the unit.
.. and also deployed the side icon and the unit textures.
From the Editor, I can set the Side ID to 2 for side 1.
This shows the new side icon.
I can also switch the side I use ("Using side 0" becomes "Using side 1").
But whatever the Side ID for side 1, it looks as if only orks were proposed ; as if on the Editor the side 1 was forced with the default GRUKKSRIPPINCREW army.
