Duncan Geere Mojang avatar.png Trapdoors have been in Minecraft since Beta 1.6 in 2011, when they were added alongside maps, grass and dead bushes. Originally they only opened 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 only be opened 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 will remain in place if their attachment block is moved, removed, or destroyed.

Usage[edit]

Properties[edit]

Wooden trapdoors can be opened and closed by players. Iron trapdoors can only be opened with redstone power.

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 will either occupy 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 will open downwards. If placed on the bottom part of a block, it will open upwards.

A trapdoor's "hinge" will be on the block it was attached to.

Trapdoors can be moved by pistons. Water can flow through trapdoors, but lava cannot. Lava can create fire in air blocks next to wooden trapdoors as if they were flammable, but the trap doors will not burn up (and can't 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.

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

Trapdoors are able to be opened or closed with a player or mob inside.[2]

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 will stop 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 only be opened 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 will immediately "rotate" 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.
