Tripwire Hook

A tripwire hook is a block used to create a tripwire circuit, which requires two hooks and a straight horizontal line of 1-40 string. Both hooks in a valid circuit emit a redstone signal and power their attached blocks while any of the string is being touched by an entity, or if any string is broken without using shears.

Obtaining

Breaking

Tripwire hooks can be broken instantly using any tool, or without a tool.

A tripwire hook is also removed and drops itself as an item if:

• its attachment block is moved, removed, or destroyed
• water flows into its space in Java Edition
• a piston tries to push it or moves a block into its space

A tripwire hook is destroyed without dropping itself as an item if lava flows into its space.

Crafting

Iron Ingot + Stick + Any Planks	2

Natural generation

Four tripwire hooks are generated naturally in each jungle pyramid. Several tripwire hooks can generate inside trial chambers next to dispensers as traps.

Fishing

Tripwire hooks can be obtained as a "junk" item from fishing.

Usage

Tripwire hooks can be used as crafting ingredients or as redstone circuit components.

Crossbow	Stick + Iron Ingot + String + Tripwire Hook

Redstone component

A tripwire hook can be used to detect mobs, items, and other entities over a large area.

Placement

To place a tripwire hook, use the Place Block control.

In order to function correctly, a tripwire hook must be part of a "tripwire circuit": a straight line of blocks consisting of a block with a tripwire hook attached to it, a "tripwire line" (1 to 40 blocks of tripwire), and a second tripwire hook attached to another block, with both tripwire hooks facing the tripwire.

To place tripwire, use the Place Block control with a string. Tripwire in a valid tripwire circuit has a short hitbox (0.09375 or 3/32 blocks high, with the bottom 0.0625 or 1/16 blocks above the block below), while tripwire not in a valid tripwire circuit has a taller hitbox (0.5 blocks high, bottom not raised).

A tripwire hook in an invalid tripwire circuit appears "folded", while a tripwire hook in a valid tripwire circuit appears extended straight. Tripwire lines from separate tripwire circuits can be placed next to each other (in parallel), above each other, and even intersecting each other.

Activation

A tripwire hook in a valid tripwire circuit activates when certain entities (players, mobs, items, etc.) intersect the tripwire hook's tripwire line "hitbox" (but not the tripwire hook itself), and deactivates when all entities leave or are removed from the tripwire line.

Entities that cannot activate a tripwire circuit include thrown potions, some arrows, fireworks, thrown ender pearls, and thrown eyes of ender.

A tripwire hook also activates for 5 redstone ticks (0.5 seconds, barring lag) when any of its tripwires are destroyed, except when shears are used to destroy the tripwire.

Breaking the tripwire hook, or breaking the block it is attached to, does not generate a pulse.

Behavior

The tripwire hooks and the blocks they are attached to provide power, but the tripwire does not.

While active, a tripwire hook appears to move downward and it:

• powers any adjacent redstone dust to power level 15, including beneath the tripwire hook
• powers any adjacent redstone comparators or redstone repeaters facing away from the tripwire hook to power level 15
• strongly powers its attachment block to power level 15
• activates any adjacent mechanism components, including above or below, such as pistons, redstone lamps, etc.

Tripwire produces no power itself, but its state change can be detected with an observer.

Although destroying tripwire with shears cannot activate a tripwire hook, it changes the tripwire hook's block state (its "attached" state from true to false), which can be detected with an observer.
