Wooden Door

The Wooden Door is a placeable object, similar to other furniture, with the added benefit of preventing the passage of enemy NPCs. It can be placed in any space so long as it is exactly 3 blocks high, with a ceiling and a floor.

Town NPCs will open and close doors as they wander about. Players can do the same by right-clicking on them. Enemy NPCs will not open doors except for Goblins, Skeletons, and Angry Bones. During a Blood Moon, Zombies can also open doors.

Each door sells for 40 copper.

Tips and tricks

 * If you use a Grappling Hook Or Ivy Whip on a door then open it, this will then launch you forward as if you were using Hermes Boots. This can be useful when leaving a house or safe room, as you quickly gain momentum and speed.
 * Doors open to the left or right based on which direction you face, rather than the direction you are coming from. For example, if a player stands to the left of a door and faces left, the door will open toward the player - to the left. If the player doesn't move and then turns to the right and opens the door, it will now open to the right.
 * Doors can also hold back water, so it seems that holding lava would also make sense. (Needs confirmation)

Trivia

 * Even though it is called a wooden door, which would make you think that there would be other types of doors, it is the only door available. This may hint at future updates.
