Editing 40d:Door

''(Note that these are mostly green [[glass]] doors, and so have the oval icon, and not the linear ones of stone, wood or metal doors, as near the stairs, bottom left.)'']]A '''door''' (called a '''portal''' when made of glass) is a piece of [[furniture]] which can be built from [[rock]] (at a [[mason's workshop]]), [[wood]] (at a [[carpenter's workshop]]), [[glass]] (at a [[glass furnace]]), or [[metal]] (at a [[metalsmith's forge]] - requires three bars). 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. {{Raw Tile|┼|0:7:1}}) Doors of different materials use different tiles. Glass doors (or portals) use the symbol {{Raw Tile|O|2:2:1}}. Metal doors use the symbol {{Raw Tile|╪|6:6:1}}. Wood doors use the symbol {{Raw Tile|║|7:6:0}}. A gem door, which can only be created by a [[strange mood]], uses the symbol {{Raw Tile|☼|7:0:0}}.

Doors made of all [[material]]s 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.

Doors may be hooked up to a [[lever]], in which case they will operate like a [[floodgate]] without any delay.

** 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.

After constructing a door at any of the above workshops, they must be "{{K|b}}uilt" (placed) like all other furniture. Doors can now be placed on any open square directly adjacent to a wall - doors cannot be placed diagonally adjacent to walls.  Other doors and [[statue]]s do not count as walls for door-building purposes.   

In this manner a line of doors can be built across a hallway wider than 2 tiles, or even into an entire "wall" of doors.  If in a line of doors, a "free standing" door can be treated as any other door - locked, linked to a [[trigger]], etc.  (A lone freestanding door cannot be locked - not that there is much point in doing so.)

Note that doors block the movement of [[wagon]]s, even in a 3 tile wide corridor; if a Dwarven or Human [[caravan]] arrives and your [[trade depot]] is behind doors one of two things will happen to any wagons: 1) If the doors are unlinked, the wagons will proceed to the doors and then stop.{{verify}} If the doors are then deconstructed, the wagons will continue with only time lost.{{verify}}  2) If the doors are linked (to a lever or pressure plate), even in the "open" state, wagons will not sense any [[path]] and will not enter the map (with the usual [[announcement]] about "bypassing your inaccessible site"), but any pack animals and caravan guards attached to them will proceed as normal.

Creatures with the [[building destroyer]] tag can destroy doors. All doors. There are no exceptions. <small>Run.</small><br />

Conversely, ''any'' door is completely invulnerable to anything that isn't a [[building destroyer]].

Thus, while a [[Troll]] can smash a masterwork [[Adamantine]] door with ease, an elite hammer[[goblin]] will be foiled by a base quality green glass portal.

Sometimes [[dwarves]] will leave items in doors, propping them open; also, if a [[vermin]] is standing in a doorway when the door would otherwise be closed, it will be killed and turned into "remains" which will also hold the door open. Having a door open when it should be closed can lead to all sorts of [[fun]] with [[water]], [[magma]] and hostile [[creature]]s. It is also impossible for a door to be forbidden or "tightly closed" while propped open, further complicating matters. One way to avoid this problem is the use of a door, chamber and then another door.  This decreases the likelihood that both doors will be jammed.

To remove an item from a doorway designate a [[Activity_zone#Garbage_Dump|garbage dump]] (preferably nearby) and then loo{{k|k}} at the item and mark it for {{k|d}}umping. A dwarf with the [[refuse]] hauling labor enabled will come along and shift it.

Note that if a [[thief]] (specifically, a creature capable of picking locks) passes through a door, the door will be marked as "taken by invaders" - you will need one of your dwarves to walk through it before you can lock it again. The easiest way to do this is station a military squad so that it passes through the door.
