String is an item that can be used as a crafting material or placed as tripwire to allow tripwire hooks and observers to detect entities that touch it.

Tripwire can be broken instantly with any tool, dropping string. Tripwire is also removed and drops string as an item when:

• Water flows into its space
• A piston pushes it or moves a block into its space

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

A cobweb drops string when it is broken in these ways (see also Cobweb § Usage):

• Breaking a cobweb with a sword
• Pushing a cobweb with a piston
• Water breaking a cobweb by flowing over it (flowing lava destroys cobwebs without leaving string)

Five pieces of tripwire generate naturally in every jungle pyramid. Several tripwires can generate inside trial chambers next to dispensers as traps.

String has a 0.5% (¹⁄₂₀₀) chance of being caught when fishing with an unenchanted fishing rod. The chance decreases to 0.4% (¹⁄₂₅₀), 0.3% (¹⁄₃₃₃), and 0.2% (¹⁄₅₀₀) if the fishing rod is enchanted with Luck of the Sea at enchantment levels I, II, and III, respectively.

Piglins may barter 3-9 string with a chance of ~4.26% (²⁰⁄₄₆₉) when given a gold ingot.

Tamed cats have a 70% chance of giving the player a gift when they wake up from a bed, and the gift has a 16.13% chance to be a string.

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

String can be placed as tripwire, which detects entities intersecting with it (players, mobs, items, etc.).

Placement

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

A line of tripwire blocks can form a simple "circuit" when placed without gaps in a straight line (1 to 40 blocks long) between two tripwire hooks that face inward toward the tripwire blocks. Multiple tripwire circuits can intersect one another, and the tripwire at each intersection can activate each circuit it belongs to.

Activation

A tripwire block is activated by any entity intersecting the tripwire hitbox, except spectators and area effect clouds. In Java Edition, the following entities also do not activate tripwire: thrown eyes of ender, the ender dragon, markers, and items clipped into solid blocks. Notably, there are some entities that still activate tripwire despite otherwise ignoring block collisions while moving, such as vexes‌^{[Java Edition only]}, and thrown eyes of ender‌^{[Bedrock Edition only]}. Active tripwires do not produce redstone power, despite their active state being referred to in-game as "powered". An observer facing a tripwire will pulse whenever it is activated or deactivated, even if it is not attached to any tripwire hooks.

Behavior​^{[more information needed]}

When any entity activates an inactive tripwire, the tripwire first updates its immediate neighbors, and then searches to the south and west looking for tripwire hooks to signal to update (no search is done toward the east or north). A search in any given direction is successful if a hook is found fewer than 41 blocks away, is facing toward the updater tripwire, and is connected to the updater tripwire by a continuous line of tripwire blocks.

After these updates are processed, the activated tripwire schedules a block tick at its own position to be processed 10 game ticks later. If the tripwire is still active during this scheduled tick, it checks whether there are any entities that should keep it activated. If there are any, the tripwire stays activated and schedules another block tick on itself for 10 game ticks later. If there are no entities that should keep the tripwire activated, the tripwire deactivates and sends the same updates as when initially activating – namely, a neighbor update and a "south-and-west signal" for tripwire hooks to update. This same set of updates is also sent when tripwire is broken (including by being washed away by spreading water in Java Edition).

If any tripwire hook is signaled to update and finds itself to be part of a valid tripwire circuit, it becomes active and produces a redstone signal in much the same way a button does.

A tripwire hook 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.

Tripwire does not prevent mobs from spawning.
