Wood trapdoors can be mined with anything, but a hatchet is speediest. Trapdoors will remain in place if their attachment object is moved, removed, or destroyed.
Crafting two trapdoors takes six Wood Beams.
Woody trapdoors can be opened and closed by players.
To place a trapdoor, use a trapdoor item while pointing at the object it should be attached to. Once it is placed, the attachment object can be removed without breaking the trapdoor.
When placed, a trapdoor will either occupy the top or bottom part of an object, depending on where the player placed the trapdoor. If a trapdoor is placed on the top part of an object, it will open downwards. If placed on the bottom part of an object, it will open upwards.
A trapdoor's "hinge" will be on the object it was attached to.
Water and lava will flow around trapdoors. Magma can create flames in air next to wood trapdoors as if they were flammable, but the trapdoors will not burn up (and ca not be burnt by other methods either).
The sound of opening and closing of a trapdoor can be heard up to 16 meters away, like every creature sound.
A trapdoor can be used as a switchable barrier to entity movement. Although primarily used to block movement by creatures and players, a trapdoor can also be used to control the movement of riverboats (for example, a top trapdoor placed in a two-wide water flow will stop a riverboat when closed (extended out into the water flow), but allow it to move again when open), items and Mine Trolleys (a trapdoor can stop a falling item or Mine Trolley, then allow it to drop again when the trapdoor opens), etc.
Trapdoors are 0.1875 (3⁄16) meters 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 woody trapdoor, click or right click control. When a trapdoor opens or closes, it immediately changes its orientation without affecting anything in the space it "passes through".
Creatures path finding consider trapdoors to always be closed, whether they are open or not. This always result in creatures falling through open trapdoors.
