A trapdoor is a non-solid block that can be used as an openable barrier.

Usage[edit]

See also: Trapdoor uses

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

Trapoors must be "attached" to a block to the side of them. To place a trapdoor, use a trapdoor item while pointing at the block it should be attached to.

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 but will drop as items if there is no valid attachment block at their new position. Water and lava will flow around trapdoors. Lava can create fire in air blocks next to wooden trapdoors as if they were flammable, but the trapdoors will not burn up (and can't be burned by other methods either).

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.

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.).

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

Redstone component[edit]

Both wood 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.

An activated wood 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).

Data values[edit]

A trapdoor is defined by its ID and block data. A trapdoor also has a block state, which is expected to replace the functionality of block data in a future version.

ID[edit]

A trapdoor's ID specifies its material:

Name ID Name Block/Item ID
Wooden Trapdoor minecraft:trapdoor 96
Iron Trapdoor minecraft:iron_trapdoor 167

Block data[edit]

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 west side of a block
  • 1: Trapdoor on the south side of a block
  • 2: Trapdoor on the east side of a block
  • 3: Trapdoor on the north 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.
