Template:Technical Block A bubble column is a block generated by placing magma blocks or soul sand in water. Bubble columns push or pull entities in certain directions.
Occurrence
Natural generation
When generating the world, caves, ravines and underwater ruins generate below the water surface. When lava generates in the former two, some lava is converted to obsidian, and some to magma blocks, which create bubble columns. All bubble columns generate bubble column blocks until the column reaches the surface of the water or a solid block above the magma block.
Post-generation
When a magma block is placed underwater, a whirlpool bubble column is generated.
When soul sand is placed under source water blocks, an upward bubble column is generated.
Obtaining
Bubble columns cannot be obtained as an item,[Java Edition only] and can be placed only by a block-placement command such as /setblock.
In Bedrock Edition, it may be obtained as an item via inventory editing.
Usage
A player or any other air-breathing mob can enter a bubble column to replenish their air supply, at the same speed that they would when they leave the water entirely. Water-breathing mobs avoid bubble columns; they die if trapped in one. A bubble column is destroyed when moved by a piston. When creating a bubble column, all blocks above must be source blocks.[Java Edition only] This requires either naturally generated water, or for the player to place a water source for each block they would like the column to reach. Placing a kelp plant up a flowing water column changes any flowing water blocks into source blocks. Bubble columns can also be created in downward flowing water,[Bedrock Edition only] however this causes all water to be converted to water source blocks. Bubble columns do not propagate through waterlogged blocks. The height of a bubble column is limited only by the water's surface or by any obstructing blocks underwater.
Whirlpool
Whirlpool bubble columns can be seen by air bubbles wandering downward. They drag entities downward. A boat ridden over a whirlpool shakes and eventually sinks if kept above the whirlpool for too long. This has a vertical range of 86 blocks.
Upward
Upward bubble columns can be seen as vertically rising air bubbles. An upward bubble column accelerates entities upward. The longer an object rises through the bubble column, the faster it travels. At high enough speeds, players and entities can be launched out of water by several blocks. Sitting on the surface above a rising bubble column causes entities to bounce upward repeatedly by about 1 block.
Transport
Entities move at a speed of approximately 15 blocks (meters) per second when inside a bubble column. This equates to a speed of 900 blocks per minute, albeit only vertically.

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.

'''Wheat seeds''' ({{in|java}}) or '''seeds''' ({{in|bedrock}}) are [[item]]s obtained by breaking [[grass]], or more abundantly harvested from wheat crops, and are used to plant them.
'''Wheat crops''' are planted in [[farmland]] and used to grow [[wheat]] and wheat seeds.
== Obtaining ==
=== Breaking ===
Harvesting fully-grown [[wheat]] [[crops]] yields from 1 to 4 seeds per crop harvested (about {{frac|2|5|7}} seeds/crop harvested on average).
Wheat seeds can be obtained from breaking all variants of [[grass]], which yields 0 to 1 seed. If harvested with a [[Fortune]] enchanted tool the drop rate from grass is increased.
The looting is calculated by a binomial distribution: a drop is attempted three times with a success rate of around 57% to yield the 0–3 drops. Each level of Fortune enchantment increases the number of attempts by one.

=== Natural generation ===
[[Village]] farm plots have a chance of being wheat crops. The exact chance depends on the style of the village:
{| class="wikitable"
! Village style !! Chance
|-
| {{EnvSprite|savanna-village}} Savanna || 80%
|-
| {{EnvSprite|desert-village}} Desert || 70%
|-
| {{EnvSprite|taiga-village}} Taiga || 60%
|-
| {{EnvSprite|plains-village}} Plains || 50%
|-
| {{EnvSprite|snowy-village}} Snowy || 20%
|}
=== Chest loot ===
{{LootChestItem|wheat-seeds}}
=== Trading ===
[[Wandering trader]]s sell wheat seeds for an [[emerald]].
=== Villager gifts ===
{{exclusive|java|section=1}}
Nitwit and unemployed [[villager]]s throw wheat seeds at players under the [[Hero of the Village]] effect.
== Usage ==
=== Crop ===
{{main|Tutorials/Crop farming|title1=Crop Farming}}
[[File:Crop states.png|thumb|Different stages of crop growth.]]
Wheat seeds can be placed on [[farmland]] by right-clicking, where they grow through eight stages. When left alone, wheat seeds planted on farmland grow to become wheat crops, which can be harvested by the player. Planted seeds require a light level of 9 or greater to continue growing. If the light level is 7 or below, the crops instantly un-plant themselves ("pop off"). It is not possible to plant seeds if the light level is too low.
Crops grow faster if the farmland they are planted in is [[Farmland#Hydration|hydrated]]. Using [[bone meal]] on crops also increases the speed of growth by randomly increasing their growth stage by 2 to 5.
Breaking the final stage produces 1 to 4 wheat seeds (or more with Fortune) and 1 [[wheat]]. If they are harvested early, they drop 1 seed without any wheat. Crops break if pushed by a [[piston]] or if their supporting farmland breaks or turns to dirt (i.e. by being trampled), dropping their usual drops.
=== Breeding ===
Like other seeds, wheat seeds can be used to breed [[chicken]]s and reduce the remaining growth duration of baby chickens by 10%. Chickens also follow a player holding wheat seeds.
=== Taming ===
Like other seeds, wheat seeds can be used to tame [[parrot]]s.
=== Composting ===
Placing wheat seeds into a [[composter]] has a 30% chance of raising the compost level by 1. A stack of wheat seeds yields an average of 2.74 [[bonemeal]].

A '''book and quill''' is an [[item]] used to write [[written book]]s.
== Obtaining ==

{{Crafting

|Output= Book and Quill
|type= Miscellaneous
}}
=== Natural generation ===
{{LootChestItem|book-and-quill}}
== Usage ==
=== Crafting ingredient ===
{{crafting usage}}
=== Writing ===
By pressing {{control|use item}} or long pressing screen anywhere{{only|bedrock}} while holding a book and quill in their hand, the [[player]] can open a text editor GUI.
Using this GUI, the player can write a single book up to 100{{only|java}} or 50{{only|bedrock}} pages long, with up to 798 characters per page. The player can write up to 79,800{{only|java}} or 12,800{{only|bedrock}} characters inside the entire book. No page may be longer than 14 lines and each line can have a width of 114 pixels (see pixel width of each character [[Language#Font|here]]).
The player has the ability to copy and paste into books. However, the paste does not work if the text being pasted is longer than a single page. Most Unicode characters are available in books, and they may be pasted in without issue.
In singleplayer, the world pauses while a book is being edited.{{only|java}}
=== Lecterns ===
One can place a book and quill or a [[written book]] on an empty [[lectern]].
The lectern then emits a redstone signal depending on the displayed page in the book. On the last page, the lectern emits a signal strength of 15. This is why lecterns are listed in the "redstone" tab in the [[creative inventory]].
=== Formatting codes ===
{{main|Formatting codes}}
{{exclusive|bedrock|section=1}}
Text in a book can be styled using codes starting with the {{key|§}} character (section sign).
* {{key|§}} + {{key|k}} creates randomly changing characters.
* {{key|§}} + {{key|l}} creates bold text.
* {{key|§}} + {{key|m}} creates strikethrough text.
* {{key|§}} + {{key|n}} creates underlined text.
* {{key|§}} + {{key|o}} creates italic text.
* {{key|§}} + {{key|0}} – {{key|f}} (hexadecimal) creates colored text.
* {{key|§}} + {{key|r}} resets any of the previous styles so text after it appears normally.
If the [[player]] uses multiple codes, and continue typing past the end of a line, the next line exhibits only the last formatting code used.
=== Signing ===
Books can be signed by pressing the "Sign" button while in the interface. {{IN|java}}, when signed, a book bears the name of the player who wrote it and a title chosen upon signing. {{IN|bedrock}}, the book doesn't display the name of the player as the author; instead, the author can be any text the player wants. After it has been signed, it cannot be edited again – it has turned into a [[written book]].
Special characters can be used in the title, if typed from a keyboard that supports them. Alt codes do not work, and the {{key|§}} character cannot be typed even using a keyboard that implements it, meaning titles cannot be colored or formatted in-game. However, on Linux using the compose key to produce special characters does work.
The title of the book can be up to 16 characters long, and the player cannot paste into a title. A "workaround" for the 16-character limitation is to manually rename the book at an [[Anvil#Renaming|anvil]], which always costs 1 [[Experience|experience level]]. This can be done with either a written book or a book and quill – both versions will always display the changed name. If a custom name is removed from a written book, it will revert back to the title it was given during the signing process.
=== Chiseled bookshelf ===
{{control|Use|text=Using}} the [[chiseled bookshelf]] while having a book and quill in the main hand will put the book inside the chiseled bookshelf.
=== Trading ===
{{IN|bedrock}}, expert-level librarian [[villager]]s buy 2 books and quills for one [[emerald]]. Book and quill is offered in two item slots due to being non-stackable.
{{IN|java}}, expert-level librarian villagers have a 50% chance to buy 2 books and quills for one emerald. The amount of books and quills needed is supposed to be 2, but due to the item being non-stackable, only one is needed for the trade.<ref>{{bug|MC-248042||Librarian's book and quill trade is always discounted to 1 since books are unstackable}}</ref>

== Trivia ==
* The in-game restrictions on books are not hard limits. Third party editors or commands can make books have more than 100 pages{{only|java}} (2,147,483,639 pages), more than 256 characters per page (32,767 characters per page), can change author names, and can have colored titles, among other things. These books still function properly in vanilla ''Minecraft'', meaning the [[player]] may encounter such books on adventure maps or multiplayer servers.<ref>http://www.minecraftforum.net/topic/1189266-hacking-books</ref>
* If the player renames a book and quill in an anvil before signing it, it retains the name from the anvil instead of taking the name from signing.{{only|java}}

A '''campfire''' is a block that can be used to cook [[food]], pacify [[bee]]s, act as a spread-proof [[light source]], smoke signal or damaging trap block.
A '''soul campfire''' is a dimmer variant of the campfire with turquoise flames. Soul campfires deal more damage than normal campfires.
== Obtaining ==
=== Breaking ===
Campfires can be mined with any tool, or without a tool, but [[axe]]s are the fastest. A regular campfire drops 2{{only|java|short=1}} or 4{{only|bedrock|short=1}} [[charcoal]], a soul campfire drops [[soul soil]], and either one also drops any items placed on it. If mined with a tool enchanted with [[Silk Touch]], the campfire instead drops itself as an item.
{{IN|BE}}, either kind of campfire can also be broken by pushing it with a [[piston]] or [[sticky piston]]. Pistons cannot move or break campfires {{in|je}}.
{{breaking row
|Campfire, Soul Campfire
|axe
|horizontal=1}}
=== Natural generation ===
Campfires can generate in {{BiomeLink|taiga}} and {{BiomeLink|snowy taiga}}{{only|be}} [[village]]s.
Campfires also generate in camps inside [[ancient city|ancient cities]], beneath a pile of blue, light blue and cyan [[wool]] blocks.

=== Trading ===
{{IN|bedrock}}, apprentice-level fisherman [[villager]]s have a 50% chance of selling a campfire for 5 [[emerald]]s.
{{IN|java}}, apprentice-level fisherman villagers have a {{frac|2|3}} chance of selling a campfire for 2 [[emerald]]s.
== Usage ==
Lit campfires emit a light level of 15 and lit soul campfires emit a light level of 10. Unlike [[fire]], campfires do not spread under any circumstances.
Campfires are lit by default when placed. Campfires can be manually lit by {{control|using}} or [[Dispenser|dispensing]] [[flint and steel]] on them, shooting it with a flaming arrow, or using or dispensing fire charges, blaze fireballs, and ghast fireballs when {{cmd|gamerule|mobGriefing}} is true. {{IN|bedrock}}, campfires can also be lit by {{control|using}} an item enchanted with [[fire aspect]], or stepping on it while burning.
Campfires can be extinguished by [[waterlogging]] it (placing [[water]] in the same block space), throwing a [[splash water bottle]] on it, or {{control|using}} a [[shovel]] on it. {{IN|bedrock}}, campfires can also be extinguished by placing a water source or allowing water to flow in the space above the campfire. As with [[torches]], rain does not extinguish campfires.<ref>{{bug|MC-141920||Rain doesn't put out campfire|Works as Intended}}</ref>
Using [[flint and steel]] on the side of a waterlogged or lit campfire sets the adjacent air block on fire instead.
Any items cooking on a campfire always drop when the campfire block is broken.
=== Particles and smoke signals ===
[[File:Campfire with smoke.gif|thumb|Campfire emitting smoke.]]
Campfires produce smoke particles that float up around 10 blocks before disappearing. If a [[hay bale]] is placed below, the campfire becomes a signal fire and the smoke floats up 24 blocks instead.
Campfire smoke particles can partially pass through a block directly above it, but do not pass through blocks more than one block directly above it.
Although a trap door is thinner than a slab, a trap door can block the smoke completely, preventing the smoke from floating up.
Campfires emit extra smoke particles during rain, similar to [[lava]].
Campfires also emit occasional ember particles, similar to lava. Soul campfires, however, do not emit embers.<ref>{{bug|MC-185482||Soul campfires do not emit ember particles|Works as Intended}}</ref>
=== Damage ===
Campfires damage [[mob]]s standing on top of them even if underwater (with exceptions such as [[shulker]]s, [[zombified piglin]]s or [[guardian]]s), but only if lit. Campfires deal {{hp|1}} and soul campfires deal {{hp|2}} of damage every tick (although [[damage immunity]] reduces this to once every half-second) Campfires do not cause lasting burning or destroy items. Damage taken is considered [[Damage#Fire|fire damage]] and is reduced by [[armor]] (which loses [[Item durability#Armor durability|durability]]), the [[Resistance]] potion effects, and the [[Protection]] and [[Fire Protection]] enchantments. The player can avoid being damaged at all, either by using a [[potion of fire resistance]] or wearing [[Frost Walker]] boots.
Regardless of [[Solid block#Height|height]], all blocks prevent damage done to mobs or players above campfires. The campfire deals damage only to entities occupying its block.
=== Cooking ===
[[File:Campfire (Cooking).gif|thumb]]
The player can place {{tooltip|raw food|raw beef, raw chicken, raw rabbit, raw porkchop, raw mutton, raw cod, raw salmon, potato, kelp}} on a lit campfire by {{control|using}} the food item on it. Up to four food items can be placed on a single campfire, which cooks the items simultaneously. Unlike other blocks that can cook food, campfires do not require any kind of fuel to cook. On a campfire, foods produce small smoke particles, indicating they are being cooked. Food items take 30 seconds (600 [[tick]]s) to cook, compared to 10 seconds for [[furnace]]s or 5 seconds for [[smoker]]s. Assuming that one uses all four slots to cook at once, the Campfire is, therefore, more efficient than furnaces (taking 10 seconds less per four items and no fuel) for cooking, but must be watched so as to pick up the food and refill it once it is done. It is slower than a smoker by about ten seconds, but its lack of fuel consumption could be seen as a worthwhile trade-off. Once finished cooking, items pop off the campfire. If the campfire is extinguished while cooking food, it resets as if it had not been cooked at all. Food items can be placed on an unlit campfire.
Other items can be placed on campfires using external editors, mods or add-ons.
=== Hoppers ===
Campfires do not have an [[Inventory#External inventories|external inventory]]. Raw food cannot be loaded into the campfire with a [[hopper]].
A hopper placed directly underneath a campfire pulls through any items dropped into the campfire. Any drops from a mob that dies in the campfire get pulled into the hopper.
=== Bees ===
Placing a campfire under a [[beehive]] or [[bee nest]] allows players to harvest [[honey bottle]]s or [[honeycomb]] without provoking the [[bee]]s.
There must be unobstructed air between the campfire and the beehive or bee nest. [[Carpet]]s are an exception.{{only|JE}}
=== Piglins ===
Lit soul campfires repel [[piglin]]s that are not currently attacking. This occurs when the [[piglin]] is within an 8 block radius of the soul campfire.
=== Light source ===
Standard lit campfires emit a light level of 15, while soul campfires emit a light level of 10. Like most other sources of light, campfires melt nearby [[snow]] and [[ice]]. Due to their lower light level, soul campfires do not melt snow or ice.
=== Note blocks ===
Campfires can be placed under [[note block]]s to produce "bass" sounds.
=== Converting soul sand to soul soil ===
Soul campfires can be used to convert [[soul sand]] into [[soul soil]]. If a soul campfire is crafted using soul sand, placed, and then broken without [[Silk Touch]], that soul campfire drops soul soil.<ref>{{bug|MC-178579||Soul campfires can be used to convert soul sand into soul soil|Works as Intended}}</ref>
=== Piston interactivity ===
{{IN|BE}}, pushing a campfire or soul campfire with a [[piston]] or [[sticky piston]] breaks it. Unlike other methods, breaking with a piston drops only one [[charcoal]] instead of two. Campfires cannot be pulled by sticky pistons.
{{IN|JE}}, pistons do not interact with campfires. Campfires neither move nor break when pushed or pulled by pistons.
