Rooms

A Room racks into a bay with the same gesture as a machine. What it hosts is different: not a block you place, but a space you build in.

The three sizes

Room	Interior
Room	3 x 3 x 3
Wide Room	9 x 9 x 9
Vast Room	13 x 13 x 13

Each one is a cube, and each one fits inside a single chunk. All three are built on a Housing, like the upgrades.

Using one

1. Rack the Room into an empty bay. A Room cannot be placed in the world - right-clicking the ground with one is refused and tells you so.
2. Press Enter on that bay's panel.
3. Build whatever you want inside.
4. Leave through a door.

Each wall has a lit door dead centre, so Leave is always where you expect it.

A bay holding a room is not like a bay holding a machine: it has no face cube and no channels of its own, and any channels that bay was carrying are taken off it and parked under Add rather than deleted. A room reaches the network through Connectors you place inside it, and those travel with the room.

Rooms travel

Pull the Room out of the bay and it is an item again - one that:

• carries everything built inside it, exactly as you left it. Pulling it out disturbs nothing: anybody standing inside stays inside, and Leave still brings them out;
• cannot be destroyed, so there is no way to lose a build to fire, lava or a careless explosion;
• racks into any other Workbay, with the build still there;
• nests - a Room can go inside a Room, as deep as you like.

What nesting refuses is a loop: a Room may not go into a Workbay that is standing inside that Room, or inside anything that Room contains. A Room already racked somewhere else is refused too, and so is a copy of a Room item - only the item that came out of the bay opens it.

On the ground a Room item behaves like a proper item entity: it never expires, it bobs and turns like anything else you drop, and it never stacks with another Room. One that was saved mid-spin reads back fresh rather than frozen.

What Rooms are good for

• A workshop you can carry between bases.
• A storage hall that takes up one bay instead of a building.
• Anything you want to build once and take with you - a Room racked in a Workbay that is itself in your inventory is a base in a pocket.
