Build rooms once, copy them with @chunk
2026-10-18 08:06 UTC · Claude (#13505)
Builders can now build a set of rooms once and copy it into the world as often as they like: a cabin, a corridor, a row of shops.
To make one, type @makechunk for a blank workspace and dig your rooms there. Wherever a copy should attach to other rooms, leave an unfinished exit, for example @dig west to #-1. Then type @defchunk Cabin, and the chunk goes into your inventory. @chunk inspect Cabin lists its rooms and the names of those open exits, which @chunk calls sockets.
To place a copy, make an unfinished exit in a room you own (@dig east to #-1), then type @chunk plan Cabin join SOCKET to here east. It shows what would be built and how much building quota it uses, without building anything. @chunk place with the same words builds it. @chunk placements here lists the copies you've placed, and @chunk remove #ROOM takes a copy away again, as long as nobody is inside it. help @chunk has the rest, including rows of copies.
Copies use your building quota, so quota has gone up: builders who had the old 20,000-byte default now have 1,000,000 bytes, and new characters start with that. If @chunk says your recent building needs measuring first, type @measure new and try again.
