Trapdoors have been in Minecraft since Beta 1.6 in 2011, when they were added alongside maps, grass and dead bushes. Originally they opened only upward, but that was later fixed so they opened down too, and the ability to climb them as a ladder was added. A bunch of different types of trapdoor have been added in the last few years - one for each type of wood, and also one made of iron that can be opened only with redstone power.

Duncan Geere[1]

A trapdoor is a solid, transparent block that can be used as an openable barrier.

Obtaining[edit]

Wooden trapdoors can be mined with anything, but an axe is fastest. Iron trapdoors require a pickaxe to mine. Trapdoors remain in place if their attachment block is moved, removed, or destroyed.

Natural generation[edit]

An oak trapdoor may be found leading to igloo basements. Various wooden trapdoors (except acacia trapdoor) generate on a shipwreck.

Oak trapdoors generate naturally in plains villages.

Spruce trapdoors generate naturally in taiga and snowy taiga villages.

Jungle trapdoors generate naturally around composters in desert villages.

Usage[edit]

Properties[edit]

Wooden trapdoors can be opened and closed by players or redstone pulse. Iron trapdoors can be opened only by redstone pulse.

To place a trapdoor, use a trapdoor item while pointing at the block it should be attached to. Once it is placed, the attachment block can be removed without breaking the trapdoor.

When placed, a trapdoor either occupies the top or bottom part of a block, depending on where the player placed the trapdoor. If a trapdoor is placed on the top part of a block, it opens downwards. If placed on the bottom part of a block, it opens upwards.

A trapdoor's "hinge" is located on the block attached to it.

Trapdoors can be moved by pistons. Trapdoors block flowing water and lava. Waterlogged trapdoors release water from all sides apart from the top‌[Bedrock Edition only] or all sides apart from the side that is blocked by the trapdoor itself (and the top)‌[Java Edition only] Lava can create fire in air blocks next to wooden trapdoors as if they were flammable, but the trapdoors do not burn (and cannot be burned by other methods either).

An open trapdoor may be climbed like a ladder if it is directly above a ladder and on the same side of the block.[more information needed]

The sound of opening and closing of a trapdoor can be heard up to 16 blocks away, like most mob sounds.

Trapdoors can be opened or closed with a player or mob inside.[2]

In Java Edition, closing a trapdoor one block above the gound while standing under it causes the player to crawl, and continue crawling until reaching a block with two empty spaces above, at which time the player stands automatically. This can be used to enter small secret tunnels or otherwise inaccessible terrain.

Barrier[edit]

A trapdoor can be used as a switchable barrier to entity movement. Although primarily used to block movement by mobs and players, a trapdoor can also be used to control the movement of boats (for example, a top trapdoor placed in a two-wide water flow stops a boat when closed (extended out into the water flow), but allow it to move again when open), items and minecarts (a trapdoor can stop a falling item or minecart, then allow it to drop again when the trapdoor opens), etc.

Trapdoors are 0.1875 (316) blocks thick. The rest of a trapdoor's space can be moved through freely and provides a breathable space if placed underwater and not waterlogged.

To open or close a wooden trapdoor, use the Use Item/Place Block control. When a trapdoor opens or closes, it immediately changes its orientation without affecting anything in the space it "passes through". Moving trapdoors don't push entities the way that pistons do.

Iron trapdoors can be opened only with redstone power (a button, a redstone circuit, etc.).

Mobs pathfinding considers trapdoors to always be closed, whether they are open or not. This often result in mobs falling through open trapdoors.

Redstone component[edit]

Both wooden and iron trapdoors can be controlled with redstone power.

A trapdoor is a redstone mechanism and can be activated by:

When activated, a trapdoor immediately rotates around its hinge side to its open state. When deactivated, a trapdoor immediately returns to its closed state. Each change of state takes one game tick.

An activated wooden trapdoor can still be closed by a player, and won't re-open until it receives a new activation signal (if a trapdoor has been closed "by hand", it still needs to be deactivated and then reactivated to open by redstone).

Fuel[edit]

Wooden trapdoors can be used as a fuel in furnaces, smelting 1.5 items per block.

Block data[edit]

In Bedrock Edition, a trapdoor's block data specifies its orientation, positioning, and activation status:

Bits Values
0x1
0x2

A two-bit field storing a value from 0 to 3:

  • 0: Trapdoor on the south side of a block
  • 1: Trapdoor on the north side of a block
  • 2: Trapdoor on the east side of a block
  • 3: Trapdoor on the west side of a block
0x4 If this bit is set, the trapdoor is open.
0x8 If this bit is set, the trapdoor is on the top half of a block. Otherwise, it is on the bottom half.
