Pressure Plate

A pressure plate is a non-solid block that can be used to detect players, mobs, items, etc.

There are two versions of the pressure plate: the stone pressure plate and the wooden pressure plate. The only difference between the two are which entities they can detect.

Obtaining
A stone pressure plate can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing. A wooden pressure plate can be mined using any tool, or without a tool, however axes are the fastest.

A pressure plate will also be removed and drop itself as an item:
 * if the block beneath it is moved, removed, or destroyed
 * if a piston tries to push it or moves a block into its space

Natural generation


One stone pressure plate is generated naturally in each desert temple.

Wooden pressure plates are generated naturally in villages on top of fences.

Usage
A pressure plate can be used to craft detector rails, to smelt items, or can be used as a redstone component.

Redstone component
A pressure plate can be used to detect entities on top of it (players, mobs, items, etc.).


 * Placement


 * To place a pressure plate, it while aiming at the face of a block adjacent to the destination space.


 * A pressure plate can be attached to:
 * the top of any full solid opaque block (stone, dirt, blocks of gold, etc.), including full-block mechanism components (command blocks, dispensers, droppers, note blocks, and redstone lamps)
 * the top of a hopper, fence, nether brick fence, an upside-down slab, or upside-down stairs.


 * A pressure plate cannot be attached to the side or bottom of any block, but attempting to make such an attachment may cause the plate to attach to the top of a block under the destination space. For example, if a fence is on the ground, attempting to attach a plate to the side of the fence will cause the plate to be attached to the top of the ground next to the fence instead.


 * Activation


 * A pressure plate activates when an entity is on top of it (specifically, when the entity's collision mask intersects the bottom quarter-block of the pressure plate's space, which may include entities flying close to the ground) and deactivates 5 redstone ticks (0.5 seconds, barring lag) after no entities are on top of it, with a minimum activation time of 10 redstone ticks (1.0 seconds, barring lag).


 * A stone pressure plate is activated only by mobs (including players), while a wooden pressure plate is activated by all entities (including players, mobs, items, arrows, experience orbs, fishing bobs, etc.) besides snowballs.


 * A minecart traveling on rails will activate a pressure plate next to a diagonal track but not one next to a straight track (stone pressure plates are activated only if the minecart contains a mob or player).


 * Behavior


 * While active, a pressure plate:
 * powers adjacent redstone dust, and adjacent redstone comparators or redstone repeaters facing away from the plate, to power level 15
 * strongly powers any full solid opaque block beneath it to power level 15
 * activates adjacent mechanism components, including above or below, such as pistons, redstone lamps, etc.

Water and lava will flow around a pressure plate without affecting it.

A pressure plate is not solid (it is not a barrier to entity movement). A block under a pressure plate can provide a solid barrier underneath it (for mobs to walk across, items to fall on, etc.), but when a pressure plate is placed on a block with a small collision mask, such as a fence or nether brick fence, it is possible for entities to move through the pressure plate while still activating it (walking through it horizontally, or falling through it vertically). Thus, a pressure plate on a fence can be used to detect entities without stopping them (more compactly than a tripwire circuit).

Pressure plates are 0.0625 blocks high ($1/16$ of a block) when inactive and 0.03125 blocks high ($1/32$ of a block) when active, but because they are not solid they do not affect the position of entities "on top" of them (for example, a player on top of a pressure plate is actually standing on the block beneath it).

Fuel
Wooden pressure plates can be used as a fuel in furnaces, smelting 1.5 items per pressure plate.

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

ID
A pressure plate's ID specifies what type of pressure plate it is.

Block data
A pressure plate's data value specifies whether is it active:
