40d:Floor

A floor is a map tile state that creatures can walk on. A floor is formed either:

1. naturally, as the ground (typically grass or a type of soil or stone),
2. by constructing walls (thus creating a floor on the level above), or
3. by specifically building a floor, using the keys b, C, f.

Floors can be built on natural floors; this distinction is subtle but allows for 'paving'. Note that designated constructions, such as stairs dug out of natural soil, can be floored over. Beware the possibility of sealing in your fort when paving your entry hall.

Constructed floors:

• count as constructions and cannot have walls built upon them.
• can have other types of buildings built upon them, such as workshops.
• can be muddied and subsequently farmed.
• cave-in when unsupported, punching through any floor tile in their way.
• cannot be smoothed or engraved.

Floors enclose spaces making the tiles below them inside.

Construction

Floors must be built up tile by tile using b -> C -> f, from which point you designate a rectangular area for construction using u, k, m and h. Building the floor itself requires either the Masonry skill (for stone and glass floors), the Carpenter skill (for wood floors), or any of the metalsmith skills (for metal floors).

Notes

Muddied constructed floor will act exactly the same as normal muddied floor, meaning tower-cap trees may grow if subterranean. This can mean havoc for reservoirs with constructed floors, including those built within chasms and bottomless pits. One prevention method to prevent growth is to build paved road over the floor^[Verify]. This can be a good use for all that extra stone.
