You can create new units, but the engine does not understand which one is the 'latest', which makes the whole thing pretty complicated. True, you can remove all default units from the tech tree and let every nation have its own unique unit to start with, but the idea of a gradual development (as in EU III) is not possible to put into practice. If you put #whatever your new unit is called# = yes as a discovery effect, the game will still let you recruit the same old default unit. Sucks. :(

EDIT: I just got an idea. You could try writing #the name of the old unit# = no as another effect, it might work. Tell me if it does!
 
Well what about putting in
allow_unit_type = cavalry
allow_unit_type = horse_archers
Only instead of cavalry, put in your new unit type? How does the game understand that a unit intrinsically needs a resource to be recruited? Does it just look through the files and see if that is anywhere? Does it only look through the trade_goods file and see if that is anywhere? Anyway I'd try that out.

I'm 99.9% certain that adding new unit types will not work, I tried it myself with adding more ships and got nothing.
 
hm... i work also on this...

a little help will be usefull. (only VV)

So i have another Idea. To bring a new Unit in the game via a new law. The law is that one that enable the new unit and/or disable the old one. And the law come into the game via invention ... so that it can be available later in time. Do you think is that possible ? But I have some questions.. I will try to do it by myself...

1. Are the Units limit hardcoded to 6 Land and 1 Naval or not ?

2. Is also possible via law (and new invention) also only to rename a already existing unit ? Ex : to rename Velites later in the game to Urban Cohorts for example ?

3. Plz tell me what for files i must change to do that..

So for a concrete Example i will add Praetorians only for the romans.. (thats will be a new Heavy-cavalery unit and only can produced in provinces that have Iron and also Horses(via trade routes) and also only available for the roman monarchy(imperium/dictatorship) system.)

So what are the files that i must change for that.. plz tell me..

So for a NEW UNIT, a new LAW and a new invention for the law..

I think it would than work with: country ={ government = monarchy }
country = { TAG = ROM }
but what are the codes that 2 ressources will build a new unit ?
also a new decision (law ) only for the roman monarchy ?
