String is an item used to make bows, crossbows, fishing rods, and leads. 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.

Drops

Spiders and cave spiders drop 0-2 string upon death. The maximum is increased by 1 per level of Looting, for a maximum of 0-5 string with Looting III.

Cats will also drop 0-2 string upon death, unaffected by Looting.

Fishing

String has a 0.6% chance of being caught when fishing with an unenchanted fishing rod. The chance decreases if the fishing rod is enchanted with Luck of the Sea.

Natural generation

Five pieces of tripwire generate naturally in every jungle temple. String can be found in 39.1% of pillager outpost chests in stacks of 1–6, and 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.

Gift

Tamed cats have a 16.13% chance of giving the player string as a gift. Cats may also drop 0-2 string if killed.

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

Novice-level Fisherman villagers have a 50% chance to buy 20 string as part of their first tier trade.

Journeyman-level Fletcher villagers buy 14 string for an emerald as part of their trade.

Redstone component

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

See also: Redstone circuit

String can be placed as tripwire, which 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	Set if tripwire is "suspended" (makes hitbox larger when set). Unclear what this is used for. Set by default on newly placed tripwires.
0x4	Set if tripwire is attached to a valid tripwire circuit.
0x8	Set if tripwire is disarmed.

Block states

Java Edition:

Name	Default value	Allowed values	Description
attached	false	false true	True if the tripwire is connected to a valid tripwire circuit.
disarmed	false	false true	True if the tripwire is disarmed, that is, broken using shears.
east	false	false true	True if the tripwire connects to other tripwire or tripwire hooks to the east.
north	false	false true	True if the tripwire connects to other tripwire or tripwire hooks to the north.
powered	false	false true	True if the tripwire is active.
south	false	false true	True if the tripwire connects to other tripwire or tripwire hooks to the south.
west	false	false true	True if the tripwire connects to other tripwire or tripwire hooks to the west.
