There is a need to move wrecks in the game without ramming them or hacking them apart.
I’m thinking of an item that when installed reduces a vehicle’s mass and makes it undrivable. It could be installed quickly with no tools and would let the player grab wrecks (up to a reasonable amount) and move them.
Having it use its own batteries (not the vehicle’s) would be a good idea.
Could modify vehicle.cpp to have if statements for things like mass\_cache but is there a cleaner approach?
Activate item and use it on a vehicle to push it one square away? How would that work?

Game has a boom crane, its just a matter of recoding vehicles so the can be joined. Thereis a PR from a while back for it I think,but didn’t have viable code or something like that.
