‘‘No bones about it, this wolf is scary. Its menacing howl empowers its skeletal brethren when they are on the prowl.‘‘

Player Journal description

The Skeleton Wolf is a variant of a wolf with a skeletal texture, found only in Minecraft Earth.

Obtaining

Skeleton wolves are a rare mob drop found in stone tappables with a very low chance of 0.1% of obtaining it. It can also be obtained as a reward in Season 6.

Behavior

Main article: Wolf § Behavior

Similar to wolves, skeleton wolves mostly have the same AI behavior. They wander aimlessly, avoiding lava and cliffs high enough to cause fall damage. However, they are not tameable, are hostile, and can howl. If a skeleton wolf howls, nearby skeleton-themed mobs gain a damage boost effect but the howling wolf does not affect itself, although it can be affected by another skeleton wolf. Additionally, skeleton wolves do not attack skeletons. Their melee attacks deal 4♥♥ and they sink in water, just like undead mobs.

Drops

When killed, an adult skeleton wolf drops:

Trivia

  • The skeleton wolf might be a reference to Grim, a skeleton dog appearing in most videos made by YouTuber DanTDM.
  • In the spawn category of the journal, it says that they spawn in the desert.

A '''head''' or '''skull''' is a [[block]] modeled after the head of a specific [[entity]]. There are seven types of heads: [[player]] ([[Steve]]'s head by default), [[zombie]], [[skeleton]], [[wither skeleton]], [[creeper]], [[piglin]], and [[dragon]].

== Obtaining ==

=== Breaking ===

A mob head can be mined using any item,<ref>{{bug|MC-192905||Heads & Skulls have no assigned tool}}</ref> and drops itself when broken.
{{breaking row|horizontal=1|Mob Head|sprite=Heads}}
If a head is pushed by a [[piston]] or comes in contact with [[water]] or [[lava]], it breaks off as an [[item (entity)|item]].

When destroyed by an [[explosion]], the head ''always'' drops as an item.

===Natural generation===

Dragon heads generate on [[end ships]] found in [[End City|end cities]].

Skeleton skulls can generate in [[ancient cities]], which sometimes generate in the [[deep dark]].

=== Mob loot ===

A [[wither skeleton]] has a 2.5% chance of dropping a wither skeleton skull when killed by a player or a tamed [[wolf]]. The chance is increased by 1% per level of [[Looting]], for a maximum of 5.5% with Looting III. {{IN|bedrock}}, the chance is increased by 2% per level of [[Looting]], for a maximum of 8.5% with Looting III.

[[Skeleton]], [[wither skeleton]], [[zombie]], [[creeper]] and [[piglin]] heads are always dropped by the respective mob if it dies due to a [[charged creeper]]'s explosion. {{IN|bedrock}}, if multiple mobs are killed by the same charged creeper, all of them drop their heads, however {{in|java}} only one mob selected at random drops its head.<ref>{{bug|MC-63534|||WAI}}</ref> If an [[ender dragon]] or a [[player]] is killed by a charged creeper, it does not drop its head.<ref name=":0">{{bug|MC-132933|||WAI}}</ref>

==Usage ==

===Decoration===

Mob heads can be oriented in 16 different directions on top of a block, and 4 directions on the sides of blocks, similar to [[sign]]s. They can be placed on top of, or beside each other by shift clicking.

When placed and powered by redstone, the piglin and dragon heads plays an animation. The piglin head flaps its ears (2 times per second for the right ear and 2.5 times per second for the left ear) while the dragon head opens and closes its mouth repeatedly (2 times per second). The same animation occurs when worn by a (horizontally) moving player, zombie, skeleton, or [[armor stand]] (note: the animation does not play if the <code>NoGravity</code> tag is set to 1)

=== Wearing ===
{{See also|#Renders}}

The player can wear heads, similarly to [[pumpkin]]s or helmets. This overlays the second layer of the player's [[skin]].

====Disguise====

Wearing the corresponding mob head reduces the detection range for [[skeleton]]s (but not [[wither skeleton]]s), [[creeper]]s, [[zombie]]s, and [[piglin]]s to 50% of the normal range. This is similar to (and stacks with) the reductions in detection range from [[sneaking]] and from the [[Invisibility]] status effect.

{{IN|bedrock}}, wearing any mob head or carved pumpkin makes the player invisible to other players on a locator [[map]].

=== Withers===
{{FakeImage|{{BlockGrid|scale=2|w=Wither Skeleton Skull|s=Soul Sand|www|sss| s }}|Wither build configuration}}

[[Wither]]s can be spawned by placing soul sand or soul soil in a T shape, and putting 3 wither skeleton skulls on top of the T. The T can be horizontal or vertical. The last block placed must be one of the three wither skeleton skulls. A dispenser can also create a wither, by placing the final skull onto soul sand directly in front of and below it.

===Dispensers===
A [[dispenser]] can equip a mob head on a player, mob, or armor stand with an empty helmet slot, within the block the dispenser is facing.

[[Dispenser]]s can also complete the construction of a wither.

=== Crafting ingredient===

  |Output= Matching Firework Star

===Enchantments===

Mob heads can receive the following enchantments, but only through an [[anvil]].

=== Note blocks ===
Placing a head above a [[note block]] causes the note block to play the corresponding mob's {{cd|ambient}} sound when activated. The only exception is the creeper head; as creepers don't make {{cd|ambient}} sounds, the note block plays the {{cd|primed}} (hissing) sound instead.

The block below the note block does not affect the mob sound it creates.

==Player skins==
{{exclusive|java|section=1}}
Human heads have an extra usage for map makers, they can be given [[Chunk format#Entity Format|NBT data]] so that they appear with the skin of any ''Minecraft'' account. This means if a player knows that a specific account has a head that is desired to display, the NBT data can be edited to make it appear.

The command to give the player a head with the skin of another player is {{cmd|give @s minecraft:player_head{SkullOwner:"<''PlayerName''>"} }}. Commonly, this kind of head is called a custom head. 

Another command to give the player a head with another player's skin is {{cmd|give @s minecraft:player_head{SkullOwner:{Id:"<''PlayerUUID''>",Properties:{textures:[{Value:"<''SkinURL''>"}]} } } }}. ''SkinURL'' is a string encoded in [https://en.wikipedia.org/wiki/Base64 Base64] containing the URL of the player's skin.<ref>Example: {"textures":{"SKIN":{"url":"<nowiki>http://textures.minecraft.net/texture/292009a4925b58f02c77dadc3ecef07ea4c7472f64e0fdc32ce5522489362680"}}}</ref> A player head saves the skin of the player from the time it was created, meaning if the player changes their skin, the head still displays the original texture.<ref>{{tweet|Dinnerbone|464414369452142592|Skulls are a snapshot of the skin as it was made; just change your skin, make a skull, and change your skin back. That's intended behaviour.|May 8, 2014}}</ref> This kind of head is generally called a custom head.

Note that it is therefore necessary to be connected to the internet to load the texture of a skin, whatever the property used.
When they are loaded for the first time by the client, the skins textures are cached in {{code|[[.minecraft]]\assets\skins\(subfolders)\(files)}}.
If the client does not have access to the internet when it first loads, the player's head displays a regular head (Steve's skin) which is also cached.
Afterwards, even if the client reconnects to the internet, in order to display the skin correctly, it is necessary to clear the cache manually by deleting the recently created files in {{code|[[.minecraft]]\assets\skins\(subfolder)}}, then restarting the game.

===Marc's Head Format ===
[[File:Allmobheads.png|thumb|right|Most of the MHF mob heads provided.]]

{{exclusive|Java|section=1}}

[[Marc Watson]] created a number of accounts with specific skins so map makers could use common heads without the risk of someone changing their skins.<ref>{{reddit|1m0itx/twitter_marc_irl_mapmakers_would_it_be_useful|cc4m1cq|I'm here to make it so that people don't have to worry about having a consistent account whose skin might change.|Marc_IRL|September 9, 2013}}</ref> Nowadays, since heads do not update the skin if a player changes their skin, this is not something map-makers need to worry about, though these skins are still useful. These accounts have names in the format <code>MHF_<''Name''></code>, for example <code>MHF_PigZombie</code> is the name of a ''Minecraft'' user with a [[zombified piglin]] head. MHF stands for "Marc's Head Format".<ref>{{tweet|Marc_IRL|377453670410891264|head format. I needed to pick a prefix that was short and not already taken by other usernames.|September 10, 2013}}</ref> There are also a few blocks and "bonus" heads, for more variety. These player heads have not been updated in compliance with the [[Texture Update]], and are outdated.

Because these are names of player accounts, these heads are obtained or placed using the <code>SkullOwner</code> tag, for instance: {{cmd|/give @s minecraft:player_head{SkullOwner:"MHF_''<Name>''"}<nowiki />}}.

The following names/heads have been made available:<ref>{{tweet|Marc_IRL|542330244473311232|For those following the MHF list, I have presents for you. Full list of accounts I've made: http://pastebin.com/5mug6EBu|December 9, 2014}}</ref>

* Heads do not have their own textures and take their textures from other objects.
* When [[breaking]] any head, the particle effect of breaking it is the same as [[soul sand]].
* Despite there being a default Steve head, heads for the other protagonist skins cannot be obtained without using custom names.
* {{IN|be}}, the skull variant for the item is stored under the {{cd|damage}} component, normally used for items with [[durability]].

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.

|A3=Stone
|B3=Stone
|C3=Stone

|type=Redstone
}}

== 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|]]]</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.
