Multiple questions on modding

[Zukhani]

1. Can navies have attrition through modding? Not the army on the ships but the actual ships. -If not would it be possible make maintenance event that would reduce ships in a sea province like attrition.
2. Is it possible to detect if two hostile navies are in the same sea zone?
3. Are title ranks hardcoded (baron, count, duke...)? Would it be possible to add more ranks?
4. I noticed that map layers (provinces, terrain, rivers) do not match exactly in vanilla, for example rivers.bmp cuts off left side of the map. Why is that?
5. How is in game distance calculated between provinces? (How long armies march from province to province)

3. Yes, these are hardcoded. Nothing we can do about that and it's very unlikely to change.
5. I think it's the amount of pixels in a straight line (presumably using Pythagoras' theorem for diagonal distances), as per provinces.bmp and other map files.

1. You could try using the damage_unit command. In the description for the damage_unit command on the wiki, they include galleys as a possible unit type, so I imagine that the command works on fleets in addition to armies. Scoping to a specific navy may be more difficult though. You would probably have to use any_fleet or random_fleet and then use a limit to scope to a specific one.

2. You can use the location scope to find the location of navies. You could probably use that to check if two hostile navies are in the same province. If you are planning to make a naval combat mod, the AI would likely get screwed by it.

4. rivers.bmp does indeed not match the other layers, I already made a bug report about it. Not sure how they missed that.
