String is used for the crafting recipes of many tools and utilities. When placed as a block, string becomes tripwire which, when combined with tripwire hooks, can form a tripwire circuit.

Obtaining

String can be obtained from drops and fishing, and can be looted from jungle temples and dungeons.

Breaking

Tripwire can be mined instantly with any tool, dropping string.

Tripwire will also be removed and drop string as an item:

• if water flows into its space
• if a piston tries to push it or moves a block into its space

Tripwire will be destroyed without dropping string if lava flows into its space.

Cobwebs

See also: Cobweb § Usage

String can be obtained from breaking cobwebs with a sword, as well as by the pushing of cobwebs by pistons and when water flows over cobwebs.

Crafting

Drops

Spiders and cave spiders drop up to two pieces of string upon death.

Fishing

String can be obtained by fishing.

Natural generation

Five pieces of tripwire generate naturally in every jungle temple.

String can be found in 57.8% of dungeon chests, 59.0% of desert temple chests, and 57.8% of woodland mansion chests, all in stacks of 1–8.

Usage

String can be used as a crafting ingredient and tripwire can be used as a redstone component. It can also be used to keep players from ender-pearling through that space.

Trading

Fisherman and fletcher villagers will buy 15-20 string for an emerald.

Redstone component

"Tripwire" redirects here. For tripwire hooks, see Tripwire Hook.

See also: Redstone circuit

Tripwire can be used to detect entities as part of a tripwire circuit.

Placement

To place tripwire, use string while pointing at a surface facing the space the tripwire should occupy.

Tripwire Circuit

In order to activate tripwire hooks, tripwire 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.

Activation

A tripwire activates if almost any entity (players, mobs, minecarts, boats, items, arrows, etc.) intersects its collision mask. The tripwire remains active until there are no entities intersecting its collision mask. Thrown potions, some arrows, thrown Ender pearls, and thrown eyes of ender will not activate tripwire.

Behavior

An active tripwire updates adjacent blocks (for example, it can activate a BUD circuit). Additionally, active tripwires that are part of valid tripwire circuits will cause the attached tripwire hooks to activate (producing redstone power). Active tripwires do not themselves produce redstone power.

When tripwire is broken (including by being washed away by spreading water) after being part of a valid tripwire circuit, it will activate the attached tripwire hooks for 5 redstone ticks (10 game ticks, or 0.5 seconds barring lag). It will not produce the signal if it is broken using shears.

Block data

See also: Data values

In Bedrock Edition, tripwire uses the following data values:

Bits	Description
0x1	Set if tripwire is activated (an entity is intersecting its collision mask).
0x2	Unused
0x4	Set if tripwire is attached to a valid tripwire circuit.
0x8	Set if tripwire is disarmed.

Block state

See also: Block states

Name	Value	Description
attached	true false	True if the tripwire is connected to a valid tripwire circuit.
disarmed	true false	True if the tripwire is disarmed, that is, broken using shears.
north  south  east  west	true false	True if the tripwire connects in that direction. For example, if east, west and south are true the tripwire is connected to either tripwire or tripwire hooks in those directions.
powered	true false	True if the tripwire is active.
