40d:Door

Doors are furniture which can be built from rock (at a mason's workshop), wood (at a carpenter's workshop), or metal (at a metalsmith's forge). You can also make glass doors (called portals) at a glass furnace. The symbol for a stone door is that of a solid tile, the color of its material, with a cross of a different color across it (e.g. ┼) Doors of different materials use different tiles, because Toady hates tileset makers. Glass doors (or portals) use the symbol O. Metal doors use the symbol ╪. Wood doors use the symbol ║.

Doors made of all materials function identically, although doors made of more valuable material will increase the "value" of a room it is used in. High-quality doors give a happy thought to any dwarf seeing them, especially when a door is part of a room that the dwarf personally owns.^[Verify] Items made of a material a dwarf has a preference for will give an even happier thought.

Doors, when closed, will prevent the passage of fluid (water and magma). However, if a dwarf opens the door, the fluid will come spilling through.

Door settings

There are three options one can specify on a door from the q menu:

• l Forbid/Permit Passage
  • A door set to Forbidden is impassable to everyone in the game. A door cannot be set Forbidden if the door is open. Invading thieves may lock-pick and bypass a Forbidden door.
• o Keep Tightly Closed/Make Pet-Passable
  • A door that is pet-passable allows through traffic of pets. A pet can still pass through a door that is tightly closed if it does so while it is being held open by an object or dwarf. This also affect the door's permeability to wild animals - a tightly closed door is a good way to keep wild animals from blundering into your fort.
• s Set as Internal/External
  • A door set to external functions as a wall when defining boundaries of a room such as a bedroom. A door set to internal allows the room boundaries to pour over.

"Building" doors

After constructing a door at any of the above workshops, they must be "built" (placed) like all other furniture. Doors can now be placed on any open square adjacent to a wall. Locked doors and statues do not count as walls for door-building purposes anymore. For the same result of the statue-door-move statue trick in previous versions to build an infinite line of doors, instead use a constructed wall segment. Doors will not "fall down" when the constructed wall is removed. They will, however, fall down if a non-constructed wall they are attached to is mined out and they have no other support.

Door construction

A door built will not create a floor above it the way a wall will. If construction is to be done above a door, walls, fortifications and floors can be built on top of doors. Doors cannot be built on top of other doors – there must be a floor. Stairs and ramps, of course, cannot be built on top of doors either.

Door strength

Trolls and most megabeasts can destroy doors.
