what i was thinking was maybe adding a electromagnet block that can be turned on and off. when turned on it would stick to a magnetic plate and could be used to make interchangeable parts on a vehicle. some good uses for this block would be, trailers hitches, it could be used to pickup and release payloads on helicopters or planes.
This is what I thought so I could make maglev train
plane tow trucks
Or maybe a it'll start as a mod but may be implemented in a future version. Would be AWESOME!@PilotOfFuture
Kidnaping other playe4s in multiplayer... even tho i think it would be hard to make, but the idea is cool
