How do I change the contruction time of a building?

[Lusted]

You can add in ownership of buildings by faction, is just most is done by culture eg barbarian.

To expand on what lusted said, you want to change this line:

        stone_wall requires factions { carthaginian, eastern, parthia, egyptian, greek, roman, }

to

        stone_wall requires factions { carthaginian, eastern, parthia, egyptian, greek, roman, dacia, }

But there is actually more to it, since there aren't any images for Dacian (or any Barbarian?) stone walls. I tried this out any got an image of a Roman army barracks in the construction options screen. When the walls had been built, the existing image of the wooden walls disappeared from the strategy map and wasn't replaced by anything.

I don't know what you need to do to supply the necessary images and don't have time to look it further; perhaps someone who knows how can help you out.

I want the dacians stone walls to look like the greek ones (white) not roman style or eastern
