Do you plan to install this canon turret on a train ? :D (will be perfect to protect the artillery just in case)

Hello,

You know I had this idea actually, but I have no clue on how to do it yet, will have to tinker about it but no promises :)

Vortik, you might try adapting some of the mod that adds turrets to vehicles, or referencing some of the code at least, I am learning lua for funsies, so I might try tackling it myself.
I think roughly what it does is get the vehicle's position and updates the position of the turrets that are attached, but I could be mistaken

Yeah checked how that mod does it and it's exaclty that, it teleports turrets around to keep them with the vehicule. It works fine for a car or tank but would probably be way too heavy regarding performance on trains.

Still studiying how to best do this feature :)

Perhaps take a look at this mod and just add a car that's compatible or talk with the mod author about adding support?
