Minecraft:Redstone Torch

Template:Distinguish Template:Infobox block A redstone torch is a non-solid Minecraft:block that produces a full-strength Minecraft:redstone signal on all sides adjacent to it, except for its attached block, and can power the block directly above it. It deactivates while the block it is attached to is powered.

Obtaining

Template:IN, the inactive redstone torch cannot be obtained as an item without commands. Template:IN, it can be obtained via inventory editing.<ref>In Java it is a block state and in Bedrock it is an entirely separate block.</ref>

Breaking

A redstone torch can be broken instantly using any Minecraft:tool, or without a tool, and drops itself as an item. Template:Breaking row A redstone torch is removed and drops as an item if:

its attachment block is moved, removed, or destroyed
Minecraft:water or Minecraft:lava flows into its space
a Minecraft:piston pushes it or moves a block into its space

Natural generation

A single redstone torch is found inside each Minecraft:igloo. In Minecraft:ancient cities, multiple redstone torches can be found integrated into circuitry.

Usage

Light

Redstone torches give off a Minecraft:light level of 7.

When the Minecraft:Render Dragon Features for Creators experiment is enabled in Minecraft:Minecraft Preview, the top part of redstone torches emits colored point lighting with Template:Color. This causes the bottom part of the torch to render a small square shadow, and the surrounding texture to render diagonal lines of shadow in all directions.

Crafting ingredient

Redstone torches can be used to craft Minecraft:activator rails, Minecraft:redstone comparators, and Minecraft:redstone repeaters. Template:Crafting usage

Redstone component

Template:See also

Redstone torches can be used to power blocks and Minecraft:transmission components such as Minecraft:redstone dust, activate Minecraft:mechanism components such as Minecraft:pistons, or invert redstone signals like a NOT Gate.

Examples of redstone torch placement and behavior

The placement conditions of a redstone torch are identical to the ones of a normal torch, it can be attached to (some exceptions might apply):

the top or sides of any Minecraft:conductive block (examples: stone, soul sand, slime blocks, dispensers, etc.)
the top of a non-conductive block that is at least 16 pixels tall and has a 2x2 pixels surface under where the redstone torch would be positioned (examples: glass panes, vertical chains, fences, etc.)
the full side surfaces of a non-conductive block (examples: glass, stairs, open trapdoors, etc.)

Redstone torches cannot be attached to the bottoms of any blocks.

Attempting to attach a redstone torch to an invalid surface can cause it to "snap" to a valid surface adjacent to the same space. For example, if a fence is on the ground, attempting to attach a redstone torch to the side of the fence causes the redstone torch to be attached to the top of the ground next to the fence instead.

Activation

A redstone torch turns off when it is powered from the back (if placed on the side of a block) or from below (if placed on top of a block) and turns on again upon being depowered. Template:IN, a redstone torch placed on a (sticky) piston turns off when the piston extends and turns on when the piston retracts: this mechanic is known by the community as "Minecraft:soft inversion".<ref>Template:Bug</ref>

Effectively, a redstone torch inverts the signal applied to its attachment block: power level 0 is changed to 15 and power levels 1 to 15 are changed to 0 (for an alternative that produces a greater range of output power levels, consider a Minecraft:redstone comparator in subtraction mode).

Walls, fences, glass, slabs, hoppers,<ref group=note>Redstone torches can be placed on hoppers only Template:In</ref> and stairs are non-Minecraft:conductive, so redstone torches attached to them cannot be deactivated.

A redstone torch takes 2 game ticks (0.1 seconds barring lag) to change state. Template:IN, redstone torches do not respond to all 2 game tick pulses.

Behavior

A lit redstone torch strongly powers the block above itself and weakly powers its other direct neighbor blocks, excluding the one it is attached to. It also produces the same Minecraft:particles as redstone dust.

A redstone torch experiences "burn-out" when it is forced to turn off more than eight times in 60 game ticks (3 seconds). After burning out, a redstone torch produces a "smoke" Minecraft:particle Template:Only and a hiss similar to an extinguished fire, deactivates, and then ignores attempts to change its state until the number of state changes in the last 60 game ticks drops to fewer than eight.

Template:IN, a redstone torch might or might not attempt to turn itself back on after 160 ticks (8 seconds) depending on the update chain that caused it to burn out.<ref>Template:Bug</ref> If the redstone torch does attempt to turn itself back on, then it is not able change state until that attempt is performed.

Template:IN, each redstone torch can only burn itself out; the redstone torch needs to be in a circuit that causes it to power itself with no delay, otherwise it does not burn out.

A burned-out redstone torch turns back on after receiving a Minecraft:block update. There is no limit on how often a single redstone torch can burn out.
