Wooden Door

Wooden Doors are blocks that when placed, can be opened and closed when players tap on them. They are commonly used to block mobs and animals from getting into certain areas, such as the player's house.

Types
There are 6 types of Wooden Doors:
 * Oak Wood Doors
 * Spruce Wood Doors
 * Jungle Wood Doors
 * Birch Wood Doors
 * Dark Oak Wood Doors
 * Acacia Wood Doors

Crafting
The type of door crafted depends on the type of wood used.
 * 6 Wooden Planks => 3 Doors

Purpose
Wooden Doors are used as openable structures that can be used to move in and out of a building, as well as keep mobs, especially hostile mobs, out, since they cannot open Doors.

There are a few exceptions:
 * Villagers can open and close Doors.
 * Zombies can break down doors on Hard difficulty.
