Ok so after extensive research I read that descr_ship.txt doesnt work at all apart from two things, ocean going and the ship type. And that's it.
So, what exactly is needed in order to be able to set up naval battles properly? I see ships in the EDU have basically the same stats as regular land troops and I dont like this one bit. Can I set up different types of weapons onboard, for example number of cannons as primary weapon and swords as secondary, so as to simulate cannonades and then boarding with sword fights between troops? Or is the game simply not reading any of that?
Can any of this be scripted in some way if that's the case?
