When I try to construct a floor in DF, it says that there is no material. What material do I need?
Floors, like all constructions, can be made from a variety of materials:
- stone, resulted from mining through rock
- blocks,made from stones (4 blocks result from one boulder), wood (only one, so pretty pointless), metal or glass.
- logs, resulted from cutting trees
- bars, resulted from... well a lot of places: metal bars from smelting ore, ash bars from burning logs, soap bars are made in a workshop from lye and tallow... and due to game limitations, all of these can be used for building.
Plus, dwarfs need a path to the future construction; if they can't get to it, they can't build it, and the game wisely, or annoyingly in some cases, prevents you from designating.
