What would be the best way to handle player owned ships on a multiplayer game. (The players may enter their ship and exit it by changing their loc. So the inside of a ship would be wall, floor turfs, and some objects)

At the back of my head, I thought I read something about a code called Rooms which creates areas at runtime? (Correct me if I'm wrong, which I probably am.)

Ships would be limited if I were to pre-create ship areas on the map, so is there a better way to do this and how would it be done?

-Thanks for reading
Seems like you are looking for this.
Hi Truseeker,

I think the library you're thinking of is Lummox JR's SwapMaps:

That is, incidentally, how I would recommend giving each player their own ship.

Hope that helps :)
