"A door for the floor."

Appearance

A trapdoor will take on some characteristics of an adjacent block or back wall. They will take on the appearance of the block to the right, the block to the left, or the backwall of its placement. If placed only adjacent to a block with bedrock as a backwall, it will usually have the appearance of wood. Viewed at an angle, they appear to be hollow with a ladder from below and have a brown, wood-like design on their top surface.

Where Found

It is created using one wood and one ladder.

Uses

Trapdoors are construction blocks that allow a Blockhead to walk on top of it normally yet climb through it as if it were absent. They are thus most effective in creating crossing horizontal and vertical paths.

When a Blockhead passes through vertically, the trapdoor will open upward, exposing the gap. It doesn't matter which direction the Blockhead approaches from or travels to, as the trapdoor always opens in the same direction. It closes automatically after the Blockhead passes.

A Blockhead may appear to pass through the side of a trapdoor under some circumstances.

If a trapdoor placed immediately above or below a solid block, it may not function properly. This state may persist if the obstruction is cleared. Resolving the problem can be as simple as removing and replacing the trapdoor.

Rails placed on trapdoors do not disable the trapdoor; a Blockhead can still go through.

Trapdoors don't burn unless the block they take the form of is wood. If so, they drop as loose items when burned.

Blockheads are the only things that can pass through trapdoors, even if water is placed on top. When a blockhead passes through a trapdoor with water on top the water stays where it is

Removing

A trapdoor will react to attempts to remove it as if it were the type of block it's taken the appearance of. This includes the appropriate tool and the number of strokes required to remove.
