Natural generation

Composters can generate in farms in villages.

Usage

Composters can be used to produce bone meal. To do so, the player must use any of a selection of items on the composter. The composter can also be used to recycle unneeded plant items. When an adjacent comparator is facing away from the composter, a comparator signal strength of up to 8 is emitted depending on the fullness of the block.

Composting

The composter can be filled with compost, which is done by adding compostable items to it. When successfully adding an item, a green particle appears. See the table below for all supported items. These items have different levels of compostability. The higher the percentage of an item, the more likely it is for that item to add another layer of compost to the block when used on it. Each layer of compost has a podzol-like appearance. When the composter reaches the 7th layer of compost, the compost will change appearance indicating that bone meal can be collected by using the composter a final time.

The following table shows the items that can be used in a composter, the percent chance for an item to add a level of compost, and the average number of items needed to fill a composter:

30% 50% 65% 85% 100%
Average number of items required to fill a composter
≈23.33 14 ≈10.77 ≈8.24 7

Hoppers

Composters can interact with hoppers by placing a composter on the upper side of a hopper and producing bone meal from the composter, which will cause the bone meal to be collected into the hopper automatically (see Hopper § Redstone component for more details about hopper-specific mechanics). Hoppers cannot be drawn into the sides of composters.

Hoppers can also push items into the composter from above.

Changing villager profession

If a village has a composter but no farmer villager, any resident villager who has not already chosen a job site block has a chance to change their profession to farmer.

Redstone component

See also: Redstone circuit

A composter can act as a power source for a redstone comparator. With a composter behind it (either directly, or separated by an unpowered solid block), a comparator will output a signal strength proportional to how full the composter is: 0 for empty, 1 for one-seventh full, 2 for two-sevenths full, 3 for three-sevenths full, 4 for four-sevenths full, 5 for five-sevenths full, 6 for six-sevenths full, 7 for completely full but the bone meal is not ready to collect, 8 for completely full and the bone meal is ready to collect. However, if there is a block between the composter and comparator, the comparator will not immediately update.

Fuel

A composter can be used as fuel in a furnace to smelt 1.5 items.

=== Fishing ===
Bowls can be obtained as a "junk" item while [[fishing]].

=== Eating ===
A bowl containing food becomes an empty bowl when the food is eaten. 

=== Mob loot ===
When a [[turtle]] is killed by a [[Thunderstorm#Lightning|lightning bolt]], it drops 1 bowl.<ref name=BowlReport>{{Cite bug|MC|125562|Turtles drop bowls when killed by lightning|date=February 16, 2018}}</ref><ref>{{Cite bug|MCPE|57038| Turtles killed by lightning drop Bowls.|date=November 17, 2019}}</ref>

== Usage ==

=== Mooshrooms ===

{{control|use|text=Using}} a bowl on a [[mooshroom]] turns the bowl into [[mushroom stew]] or [[suspicious stew]]. The stew can then be consumed immediately and the process repeated, making this an excellent way to quickly restore depleted [[hunger]] and [[saturation]] with almost no cost or effort.

=== Fuel ===
Bowls can be used as a fuel in [[furnace]]s, smelting 0.5 items per bowl {{in|je}}, and 1 item per bowl {{in|be}}.

== Trivia ==
* {{in|be}}, bowls are actually more fuel efficient than [[stick]]s. If 6 wood planks are crafted into 8 bowls, 8 items can be [[smelt]]ed; but if those are crafted into 12 sticks, only 6 items can be smelted. This can be useful when the player only has access to Nether wood types, which cannot be used as fuel.

When a chicken dies while on fire, it drops one cooked chicken. The maximum is increased by 1 per level of [[Looting]], for a maximum of 1–4 cooked chicken with Looting III.

=== Cooking ===

[[Raw chicken]] can be cooked in a [[furnace]], [[smoker]], or [[campfire]]. Each piece of cooked chicken removed from a furnace output slot gives 0.35 [[experience]] (22.4 experience per stack).
{{Smelting
|Raw Chicken
|Cooked Chicken
|0,35
}}

=== Trading ===
{{IN|java}}, apprentice-level butcher [[villager]]s have a {{frac|2|3}} chance to sell 8 cooked chicken for an [[emerald]]. 

Butcher villagers may give cooked chicken to players with the [[Hero of the Village]] effect.{{only|java}}

{{IN|bedrock}}, apprentice-level butcher villagers have a 25% chance to sell 8 cooked chicken for an emerald as part of their trades.

== Usage ==
=== Food ===

To eat cooked chicken, press and hold {{control|use}} while it is selected in the hotbar. Eating one restores {{hunger|6}} [[hunger]] and 7.2 hunger [[Hunger#Mechanics|saturation]].

{{about|the block|repeater circuits|Transmission circuit#Repeater|other topics related to redstone|Redstone (disambiguation)}}
A '''redstone repeater''' is a [[block]] that produces a full-strength [[Redstone Dust|output signal]] from its front when its back is powered, with four configurable delay settings. It can also be locked into a power state by its side being directly powered by a repeater or a [[Redstone Comparator|comparator]].

== Obtaining ==
=== Breaking ===
A redstone repeater can be broken instantly using any [[tool]], or without a tool, and drops itself as an item. To remove a redstone repeater, {{control|mine}} it.

A redstone repeater is removed and drops as an item if:
* its attachment block is moved, removed, or destroyed;
* [[water]] or [[lava]] flows into its space;{{only|java}}
* a [[piston]] tries to push it or moves a block into its space.

=== Natural generation ===
[[File:Redstone Repeater naturally generated.png|thumb|A redstone repeater generated in the jungle temple's hidden room.]]
A single redstone repeater is generated naturally in each [[jungle temple]].
They also generate in [[Ancient City|ancient cities]].

== Usage ==
{{see also|Redstone circuit}}
A redstone repeater can be used in four different ways: to "repeat" redstone signals back to full strength, delay signals, prevent signals moving backwards, or to "lock" signals in one state.

A repeater can be placed only on top of [[opaque]] blocks (dirt, stone, etc.), on top of upside-down [[slab]]s, upside-down [[stairs]], furnaces, and glass. {{IN|be}}, a repeater can also be placed on fences and stone walls. They can also be placed on some transparent blocks. See [[Opacity/Placement]] for more information. To place a repeater, use the {{control|Place Block}} [[control]].

A redstone repeater has a front and back – the arrow on the top points to the repeater's front. A repeater also has two small redstone torches on its top – the color of the torches indicates whether its output is on (dark red when off, bright red when on) and the distance between them indicates the delay the repeater adds to the signal transmission.

A repeater is 0.125 ({{frac|1|8}}) blocks high.

=== Signal transmission ===
A repeater transmits signals only from its back to its front, but its behavior can be modified from the side (see [[#Signal locking|signal locking]], below).

[[File:Redstone Torch Power.png|Different ways to power a repeater|thumb]]
A redstone repeater can be powered by any of the following components at its back:
* an active [[power component]] (redstone torch, lever, block of redstone, etc.)
* powered [[redstone dust]]
* a powered [[redstone comparator]] or another powered redstone repeater facing the repeater
* a powered opaque block (including any opaque [[mechanism component]]s, such as [[dispenser]]s, [[redstone lamp]]s, etc.)

A redstone repeater can power any of the following components at its front:
* redstone dust
* a redstone comparator or another redstone repeater facing away from the repeater
* any opaque block (including any opaque [[mechanism component]]s)

A redstone repeater can activate any [[mechanism component]] it is facing.

An opaque block powered by a redstone repeater is called "strongly-powered" (as opposed to an opaque block "weakly-powered" by redstone dust). A strongly-powered opaque block can power adjacent redstone dust, as well as other redstone components.

=== Signal repeating ===
{{see also|Transmission circuit#Repeater}}
A redstone repeater can "repeat" a [[Redstone Dust|redstone]] signal, boosting it back up to power level 15.

Redstone signals have a maximum power level of 15 and that level drops by 1 for every block of [[redstone dust]] the signal travels through. If a signal must travel through more than 15 [[block]]s of redstone dust, a redstone repeater can be used to boost the signal back up to full strength. An extra two blocks of distance can be achieved by placing solid opaque blocks before and after the repeater.

While redstone repeaters can allow signals to travel great distances, each always adds some delay to the transmission since the minimum amount of delay is 1 redstone tick (0.1 seconds, barring lag).

=== Signal delay ===
When initially placed, a redstone repeater has a delay of one [[redstone tick]] (equivalent to two game ticks, or 0.1 seconds barring lag).

A repeater's delay can be modified by using the {{control|Use Item}} control. Each use increases the repeater's delay by one redstone tick, to a maximum of four redstone ticks, then back to one redstone tick. Longer delays can be made with multiple repeaters – for example, a repeater set to 'four' and another to 'one' provides a half-second delay (0.4s + 0.1s = 0.5s).

A repeater set to a delay of two to four redstone ticks increases the length of any shorter [[Pulse circuit#Pulses|on-pulse]] to match the length of the repeater's delay, and suppress any shorter off-pulse. For example, a repeater set to a 4-tick delay changes a 1-tick, 2-tick, or 3-tick on-pulse into a 4-tick on-pulse, and does not allow through any off-pulse shorter than 4 ticks.

Although a repeater cannot be set to have a delay of zero, [[Transmission circuit#Instant repeater|instant repeater circuits]] are possible (circuits that repeat a signal with no delay).

In Bedrock Edition, the first repeater have a delay of zero but the repeater is still showing 1-tick{{info needed}}

=== {{anchor|diode}} Signal direction ===
{{see also| Mechanics/Redstone/Transmission circuit#Diode}}

A redstone repeater acts as a diode – it allows redstone signals through in one direction (unlike [[redstone dust]] or opaque blocks that can transmit redstone signals in any direction).

A diode can be used to protect a [[redstone circuit]] from redstone signals feeding back into the circuit from its output, or can be used to isolate one part of a circuit from another.

=== {{anchor|lock}} Signal locking ===
{{see also| Mechanics/Redstone/Memory circuit}}
[[File:Latch.png|thumb|The left repeater has been locked in an unpowered output state by the right repeater.]]
A redstone repeater can be "locked" by another powered redstone repeater facing its side. When locked, the repeater does not change its output (whether powered or unpowered), no matter what the input does. When the side repeater turns back off, the repeater returns to its normal behavior.

A repeater can also be locked by a powered [[redstone comparator]] facing its side. This offers additional possibilities for locking signals because a comparator's output can be affected from 3 sides as well as by containers.

If a repeater is locked again too quickly after unlocking (e.g. the lock is controlled by a fast clock circuit), or the lock and the input are changed only on the same tick (e.g. because they're fed by the same clock and both repeaters have the same delay), the repeater does not switch states.

A '''redstone comparator''' is a [[block]] that can produce an [[Redstone Dust|output signal]] from its front by reading [[chest]]s, [[lectern]]s, [[beehive]]s and similar blocks, or repeat a signal without changing its strength. It can also be set to either stop outputting a signal when its side input recieves a stronger one (front torch off), or subtract its side input's signal strength from its output (front torch on).

== Obtaining ==
=== Natural generation ===
Redstone comparators generate in [[Ancient City|ancient cities]].

=== Breaking ===
A redstone comparator can be broken instantly with any [[tool]], or by hand, and drops itself as an item.

{{Breaking row|Redstone Comparator|horizontal=y}}

A redstone comparator is removed and dropped as an item if:
* its attachment block is moved, removed, or destroyed;
* [[water]] flows into its space;{{only|java}}
* a [[piston]] tries to push it or moves a block into its space.

If [[lava]] flows into a redstone comparator's space, the redstone comparator is destroyed without dropping as an item.

}}

== Usage ==
A redstone comparator can be placed on the top of any [[opaque]] block with a solid full-height top surface (including upside-down [[slab]]s and upside-down [[stairs]]). {{IN|be}}, a comparator can also be placed on [[wall]]s and fences. For more information about placement on transparent blocks, see [[Opacity/Placement]].

The redstone comparator has a front and a back — the arrow on the top of the comparator points to the front. When placed, the comparator faces away from the player. The comparator has two miniature redstone torches at the back and one at the front. The back torches turn on when the comparator's output is greater than zero (the arrow on top also turns red). The front torch has two states that can be toggled by {{control|using}} the comparator:
* Down and unpowered (indicating the comparator is in "comparison mode")
* Up and powered (indicating the comparator is in "subtraction mode")

The redstone comparator can take a signal strength input from its rear as well as from both sides. Side inputs are accepted only from [[redstone dust]], [[block of redstone]], [[redstone repeater]]s, other comparators, and [[observer]]s in specific scenarios. The redstone comparator's front is its output.

It takes 1 [[redstone tick]] (2 game ticks, or 0.1 seconds barring lag) for signals to move through a redstone comparator, either from the rear or from the sides. This applies to changing signal strengths as well as simply to turning on and off. 

Redstone comparators check their power state before their scheduled ticks update. This results in redstone comparators not usually responding to 1-tick fluctuations of power or signal strength — for example, a [[clock circuit|1-clock]] input is treated as always off from the side, and always on from the rear. This happens because the signal changes back to its original state before the redstone comparator checks its input states. However, certain setups such as powering any input with two separate observer pulses at the same time will cause a redstone comparator to respond to 2 gametick pulses.

The redstone comparator has four functions: maintain signal strength, compare signal strength, subtract signal strength, and measure certain block states (primarily the fullness of containers).

=== Maintain signal strength ===
A redstone comparator with no powered sides outputs the same signal strength as its rear input.

=== Compare signal strength ===
[[File:Comparators Explained.png|Comparators in comparison mode.|thumb]]
A redstone comparator in comparison mode (front torch down and unpowered) compares its rear input to its two side inputs. If either side input is greater than the rear input, the comparator output turns off. If neither side input is greater than the rear input, the comparator outputs the same signal strength as its rear input.

The formula for calculating the output signal strength is as follows:

<code>output = rear × [[Wikipedia:Iverson bracket|[]]'''''left''''' ≤ '''''rear''''' AND '''''right''''' ≤ '''''rear'''''[[Wikipedia:Iverson bracket|<nowiki>]]]</code>
{{-}}

=== Subtract signal strength ===
[[File:Redstone comparator.png|thumb|The greatest of the side inputs A and C is subtracted from the rear input B, outputting 1. If either A or C were greater than B, it would output 0.]]
A redstone comparator in subtraction mode (front torch up and powered) subtracts the signal strength of the higher side input from the signal strength of the rear input.

<code>output = max('''''rear''''' − max('''''left''', '''right'''''), 0)</code>

For example: if the signal strength is 6 at the left input, 7 at the right input and 4 at the rear, the output signal has a strength of ''max(4 − max(6, 7), 0) = max(4−7, 0) = max(−3, 0) = 0''.

If the signal strength is 9 at the rear, 2 at the right input and 5 at the left input, the output signal has a strength of ''max(9 − max(2, 5), 0) = max(9−5, 0) = 4''.

=== Measure block state ===
{{Schematic | caption = A redstone comparator can measure the fullness of a chest, as well as other block states, even through an opaque block.
 |rd-ew!|rc-w!|ch|SB|rc-e!|rd-ew!
}}
A redstone comparator treats certain blocks behind it as power sources and outputs a signal strength proportional to the block's state. The comparator may be separated from the measured block by an opaque block. However, {{in|je}}, if the opaque block is powered to signal strength 15, then the comparator outputs 15 no matter the fullness of the container.<ref>{{bug|MC-64394}} (resolved as "Works As Intended")</ref>

A redstone comparator can output a signal indicating how full a container is. (0 for empty, 15 for full, etc.) The table on the right is described more in detail, later in this section.

Containers that can be measured by a comparator include:
* {{BlockLink|Furnace}}
* {{BlockLink|Blast Furnace}}
* {{BlockLink|Smoker}}
* {{BlockLink|Brewing Stand}}
* {{BlockLink|Hopper}}
* {{ItemLink|Minecart with Hopper}} on top of a [[detector rail]]
* {{BlockLink|Dispenser}}
* {{BlockLink|Dropper}}
* {{BlockLink|Chest}}
* {{BlockLink|Trapped Chest}}
* {{ItemLink|Minecart with Chest}} on top of a [[detector rail]]
* {{BlockLink|Barrel}}
* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large chest
* {{SchematicSprite|size=16|ch-e}}{{SchematicSprite|size=16|ch-w}} Large trapped chest
* {{BlockLink|Shulker Box}} (any color)

Generally speaking, the comparator output signal strength represents the average fullness of the slots, based on how many of that item form a full stack (64, 16, or 1 for non-stackable items).

The ''Minimum Items for Container Signal Strength'' table (right) shows the minimum '''''full-stack-equivalent (FSE)''''' to produce different signal strengths from common containers. A '''''full-stack-equivalent''''' quantifies how many normal 64-stackable items are needed to output a corresponding signal strength. The 's' is a constant 64, with the additional amount needed following after.

One may also consider the terms: '''c''umulative-weight''''' or '''''weighted-sum''''' instead of '''''full-stack-equivalent'''''.

Items that stack to a max of 16  ([[snowball]]s, [[sign]]s, [[ender pearl]]s, etc.), contribute +4 to the ''full-stack-equivalent'' for each unity (count of 1 item). Similarly, items that stack to 1 ([[minecart]], [[boat]], etc.) contribute +64, and items that stack to 64 contribute +1.

Example 1: 3 ender pearls will contribute a 3 x 4 = 12 ''full-stack-equivalent''.

Example 2: 16 ender pearls and 60 redstone dust contributes a 16x4 + 60x1 = 124 ''full-stack-equivalent''.

Example 3: 1 minecart and 60 redstone dust contributes a 1x64 + 60x1 = 124 ''full-stack-equivalent''.

Example 4: To produce a signal strength of 10 from a hopper, one requires a ''full-stack-equivalent'' of at least 3s + 14 = 206 but strictly less than than 3s + 37 = 229. This can be done with 3 minecarts, and 14 dirt.

When a comparator measures a large chest or large trapped chest, it measures the entire large chest (54 slots), not just the half directly behind the comparator. A chest or trapped chest that cannot be opened (either because it has an opaque block, [[ocelot]], or [[cat]] above it) always produces an output of 0 no matter how many items are in the container — shulker boxes can always be measured, even if they cannot open.

;Calculating signal strength from items

:When a container is empty, the output is off.

:When it is not empty, the output signal strength is calculated as follows:

:<code>'''''signal strength''''' = floor(1 + (('''''sum of all slots' fullnesses''''') / ('''''number of slots in container''''')) × 14)</code>

:<code>fullness of a slot = '''''number of items in slot''''' / '''''max stack size for this type of item'''''</code>

:''Example:'' 300 blocks in a dispenser (which has 9 slots), where each block stacks to a maximum of 64 has a 300 ''full-stack-equivalent.'' This produces an output with a signal strength of 8:
<blockquote>
1 + ((300 items / 64 items per slot) / 9 slots) × 14 = 8.292, floored is 8
</blockquote>

;Calculating items from signal strength

:It can be useful in redstone circuits to use containers with comparators to create signals of a specific strength. The number of items required in a container to produce a signal of desired strength is calculated as follows:

:<code>items required = max('''''desired signal strength''''', roundup(('''''total slots in container''''' × 64 / 14) × (desired signal strength − 1)))</code>

:''Example:'' To use a furnace (which has 3 slots) to create a strength 9 signal, players need 110 items:
<blockquote>
max(9, (3×64/14) × (9−1)) = 109.714, rounded up is 110
</blockquote>

==== Miscellaneous ====
[[File:Comparator storage.png|Comparators used to measure containers.|thumb]]
Some non-container blocks can also be measured by a redstone comparator:

;{{BlockLink|Beehive}} and {{BlockLink|Bee nest}}

: A hive or nest outputs a signal strength equal to the amount of honey in the hive/nest.

;{{BlockLink|Cake}}

: A cake outputs a signal strength relative to the amount of cake remaining.  Each slice is worth 2 signal strength, with 7 total slices, for an output of 14 for a full cake.

[[File:Cauldron Redstone Strength Values.png|Cauldron signal strength|thumb]]
;{{BlockLink|Cauldron}}

: A cauldron outputs different signal strengths depending on how much water or powdered snow is inside. From completely empty to completely full, the output values are 0, 1, 2, and 3. If lava or powder snow is inside, the strength is always 3.

[[File:Composter Redstone Strength Values.png|Composter signal strength|thumb]]
;{{BlockLink|Composter}}

: A composter outputs different signal strengths depending on the level inside. From completely empty to completely full, the output values are 0, 1, 2, 3, 4, 5, 6, 7 and 8.

;{{Anchor|CommandBlock}}{{BlockLink|Command Block}}

: A command block stores the "success count" of the last command executed, which represents the number of times the most recently used command of this command block succeeded. A "success" is defined by the [[command]]'s success conditions: if a red error message is returned in the chat, the command was not successful.

: Most commands can succeed once per execution, but certain commands (such as those that accept players as arguments) can succeed multiple times, and the comparator outputs the number of times it succeeded (maximum 15 when sent to redstone dust, but in the code it is able to go up to the 32-bit integer limit, and can be used in contraptions with no redstone dust with those values).

: A command block continues to store the success count of the last command executed until it executes its command again, thus the comparator continues to output the same signal strength even after the command block is no longer being activated (it doesn't turn off when the signal to the command block turns off).

;{{BlockLink|End Portal Frame}}

: An end portal frame outputs a full signal of 15 if it contains an [[eye of ender]] and zero otherwise.

[[File:Item frame and comparator.png|A comparator can measure the presence and rotation of an item frame's contents.|thumb]]

;{{EntityLink|Item Frame}}

: A comparator can measure the state of an [[item frame]]'s contents. An item frame comparator outputs 0 if the item frame is empty, or 1 to 8 for any item depending on its rotation: 1 at initial placement, plus 1 for each 45° of rotation for a maximum of 8.

: For an item frame that holds a map, a unit of rotation is 90° instead of 45°, but a comparator still outputs power levels 1 to 8. It takes two full rotations to cycle through all comparator outputs, and each orientation of the map corresponds to two output levels that differ by 4.

: The comparator must be placed behind the block the item frame is attached to, facing away from the item frame. The block must be a full block, and the item frame cannot be submerged in water. Having a sign in the same block as the item frame will prevent the frame from sending a signal as well.{{only|java}}

;{{BlockLink|Jukebox}}

: A jukebox outputs a signal strength indicating which music disc is currently playing. See the ''Minimum Items for Container Signal Strength'' table above.

;{{BlockLink|Lectern}}

: A lectern outputs a signal strength that depends on what page the player is currently on. The calculation used is:
:<code>'''''signal strength''''' = floor(1 + (('''''current page''''' - 1) / ('''''number of pages in book''''' - 1)) × 14)</code>
:This results in page 1 having a signal strength of 1, and the last page having a signal strength of 15. The exception is a single page book, which will output a signal strength of 15.
:For example, a book with 15 pages will output a signal equal to the current page number.  A book with 5 pages will output signal strengths of 1, 4, 8, 11 and 15 for the different pages. A book with 100 pages will have the signal strength increase to the next level on pages 1, 9, 16, 23, 30, 37, 44, 51, 58, 65, 72, 79, 86, 93 and 100.
:

;{{BlockLink|Respawn Anchor}}

: A respawn anchor outputs a signal strength of 0, 3, 7, 11, or 15, depending on the "charged" value.

;{{BlockLink|Sculk Sensor}}

: A sculk sensor outputs a signal strength depending on the type of vibration that is detected.

;{{BlockLink|Chiseled Bookshelf}}

: A chisled bookshelf outputs a signal strength between 1 and 6 indicating the last slot interacted with. When no slot has been interacted with yet, it outputs 0.
