So I posted an idea of mine here and wanted to try it out on a modded map. I've already tried a bit through some trial and error without luck.
Question: Is there a way to define different properties for a unit for different factions? I'm looking for the medium tank 2TNK to cost 1050 for Germany and 850 for France/England. Also I'm looking for the 90mm weapon to do different damage for different factions as well. I've recently delved into map modding so I'm currently on a steep learning curve
You can, for example, crate a new unit and give it the same properties as the tank you seek.
As for production of your unit maybe look into production queue for war fac?
I managed to make a German Medium Tank inherit the regular Medium Tank and fix prerequisites as to make it exclusive to Germany, plus make the regular Medium Tank exclusive to the remaining Allied factions.
