Wooden Door

A Wooden Door is a simple mechanism that can be opened using the right mouse button. They can be opened either way, depending on which direction a player is facing when he/she opens the door. Doors must have a block below and above them to be placed, and if one of these blocks are removed after placement, the door will be removed along with the block.

To place a door, click either the upper or lower attachment point. In the picture to the right, this would be just below the bottom of the wooden wall that it is attached to or just above the ground.

They are three blocks high and can be used to keep out monsters, make rooms for NPCs to live in, or just for decoration. They can be crafted with 6 Wood at a Work Bench.

Teleporting and burrowing enemies can circumvent doors, Skeleton monsters, Werewolves, Possessed Armour and Zombies during a Blood Moon can open doors, and Goblin Warriors, Goblin Thieves can break down doors.

A door won't open if the direction the player is facing while opening the door is blocked by other placeable blocks (such as bricks, dirt, chests, anvil, etc).

You can make a door which cannot be opened by Zombies during a Blood Moon by adding a wooden platform to the top of the inside of the doorway. This prevents the door from opening for Zombies on the outside, but still allows you to open it as you need. Placing a wooden beam on the inside of the door will achieve a similar effect. This can be useful because you don't need to worry about barricading all your doors during a Blood Moon as they are already blocked off, but still useable. However, be aware that this will not prevent Goblins from simply breaking the door down regardless.

Trivia

 * An open door can support sand allowing it to be a trigger for a trap.
 * A door will also block the flow of water when closed, and will allow water to flow through when open, which allows the door to be used as a sort of floodgate.
 * Two doors placed next to each other with no space inbetween must be opened by right-clicking the farthest one while facing it, and the nearest one while facing the other direction. NPCs, however, can apparently open doors in either direction without facing the other way, so they walk through unphased, though they sometimes forget to close one. It is unknown if monsters also have this ability.
 * The door's icon in the inventory refers to it as "Wooden Door".
 * A door also opens and closes when it is powered with a wire. This way, you can make an automatic door by placing Pressure Plates on both sides of a door and connecting them and the door with wires.
 * Sometimes, when a NPC opens a door, it will disapear. However, it still remains valid housing.
