These dastardly creations are made from a handful of pretty basic ingredients, but are perfect for setting up traps for mobs, animals or even other players. To set up a tripwire, you need to place two tripwire hooks facing each other, and connect them with string. It’ll then sit there until a player walks through the string, at which point you’ll hear a "click" and the hooks will send out a redstone pulse.

— Duncan Geere[1]

A tripwire hook is a block that can be used to detect entities (players, mobs, items, etc.) when part of a tripwire circuit is passed through.

Natural generation[edit]

Four tripwire hooks are generated naturally in each jungle temple.

Obtaining[edit]

Breaking[edit]

To remove a tripwire hook, mine it. 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 and Legacy Console editions
  • 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[edit]

Chest loot[edit]

Tripwire hooks can be found in 30.5% of pillager outpost chests in stacks of 1–3.

Usage[edit]

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

Redstone component[edit]

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.
A tripwire hook can be attached to the side of any full solid block, with the inexplicable exception of blocks of redstone and observers.[2]
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).

The three states of a tripwire hook: not attached (folded), attached (straight), activated (depressed).
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 "hit box" (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:
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.

Trading[edit]

Master-level fletcher villager have a 2⁄3 chance to buy 8 tripwire hooks for an emerald as part of their trades in Java Edition, and always offer the trade in Bedrock Edition.

Data values[edit]

Block data[edit]

See also: Data values

In Bedrock Edition, a tripwire hook's block data stores its orientation, connection status, and activation status:

Bits Values
0x1
0x2

A two-bit field storing a value from 0 to 3:

  • 0: Tripwire hook on block side facing south
  • 1: Tripwire hook on block side facing west
  • 2: Tripwire hook on block side facing north
  • 3: Tripwire hook on block side facing east
0x4 If set, the tripwire hook is connected and ready to trip ("middle" position).
0x8 If set, the tripwire hook is currently activated ("down" position)

Block states[edit]

See also: Block states

Java Edition:

Name Default value Allowed values Description
attachedfalsefalse
true		True if the tripwire hook is connected to a valid tripwire circuit.
facingnortheast
north
south
west		The direction in which the tripwire hook juts out from the block it is attached to.
For example, a tripwire hook facing north will be attached to a block to its south.
poweredfalsefalse
true		True if the tripwire hook is active.

Video[edit]

Note: This video does not show the tripwire hook obtained from fishing, or its crafting usage.

History[edit]

Java Edition
1.3.1May 28, 2012Dinnerbone released a series of cryptic tweets, starting with "I think I'm taking a big liking toward adventure maps. It's starting to show in my choice of new blocks."[3] He hinted at shears being used to disable the tripwire,[4] then posted a series of images[5][6][7] before revealing the name.[8] Afterward, he posted a video[9] to reveal the functionality of the tripwire and finally credited the idea to his fiancee MissMarzenia.[10]
