Java Edition unused features

This article is about features that are in the game, but unused. For unused ideas, see Java Edition mentioned features.

Since the beginning of Minecraft's development, there have been a number of features added to the game that have no actual use in Survival or in Creative. Some of these features are leftover from removed features, or simply placeholders for new features.

Note that this page only documents unused features that are currently in the game. See Java Edition removed features for features previously in the game that are no longer available.

Blocks‌

Seamless slabs

See also: Slab

All double slabs above data value 8 have the seamless tag. This displays the top texture of the slab on all 6 sides. This is only visible on four slabs: stone, sandstone, red sandstone and quartz. All other seamless slabs look identical to their normal counterparts. Breaking seamless slabs will yield two of their respective slabs, which will create normal double slabs if stacked. Seamless slabs can be obtained in versions 14w25a and below and 17w47a and above. In the upcoming 1.13 update they will be renamed to Smooth. They can be obtained by using the following commands:

Block	pre-1.13	1.13
Smooth Stone	/give <player> double_stone_slab 1 8‌	/give <player> smooth_stone‌
Smooth Sandstone	/give <player> double_stone_slab 1 9‌	/give <player> smooth_sandstone‌

It can be obtained by either NBT editors, inventory editors, or glitches in Bedrock Edition. To get the block form of the camera in Bedrock Edition using an NBT editor you need to set the item name of the block in the inventory slot (<code>name:</code> ) to <code>item.camera</code>, then you need to add a compound tag called <code>Block</code> and inside of that put the int tag <code>version: 18040335</code> and the text tag <code>name: minecraft:camera</code> into the block compound tag. For the usable item / spawn egg form of the camera you just need to set the item name of the block in the inventory slot (<code>name:</code> ) to <code>camera</code>, you don't need to add the block compound for this form of the camera though. == Usage == Using a camera from one's [[inventory]] captures a first-person screenshot. It may also be placed, creating a camera [[entity]] that can track the user, and take pictures from the camera's perspective. Photos that are taken with the camera appear in the [[portfolio]]. Close-up snapshots of an [[item]] on the ground can be taken by holding the Shift key while right-clicking. Photos that are taken with the camera block are stored in <code>%localappdata%\Packages\MinecraftUWP_8wekyb3d8bbwe\LocalState\screenshots</code>. == Sounds == === Generic === {{Sound table/Block/Normal/BE}} === Unique === {{Sound table |sound=Camera1.ogg |sound2=Camera2.ogg |sound3=Camera3.ogg |type=bedrock |description=When a picture is taken with a camera |source=Players |id=camera.take_picture |volume=1.0 |pitch=1.0 |foot=1}} == Data values == === ID === {{ID table |edition=bedrock |firstcolumnname=Camera |shownumericids=y |showforms=y |generatetranslationkeys=y |displayname=Block |spritename=camera |spritetype=block |nameid=camera |id=242 |form=block |itemform=item.camera}} {{ID table |displayname=Item |spritename=camera |spritetype=item |translationtype=item |nameid=camera |id=593 |form=item |foot=1}} {{ID table |edition=bedrock |firstcolumnname=Camera |shownumericids=y |generatetranslationkeys=y |displayname=Entity |spritename=camera |spritetype=entity |nameid=tripod_camera |id=62 |foot=1}} === Entity data === See [[Bedrock Edition level format/Entity format]]. == Video == {{yt|1XLRGFibFNQ}} == History == {{History|pocket alpha}} {{History||v0.1.0|[[File:Camera BE1.png|50px]] [[File:Camera (item texture) BE1.png|32px]] The textures and model of the camera can be found in the game apk file.<ref name="found">[{{Reddit|jkkmr/found_image_file_for_camera_in_minecraft_portable}} Reddit - Found image file for camera in Minecraft Portable Edition Demo APK file.]</ref><ref>https://web.archive.org/web/20160604161800/https://twitter.com/Kappische/status/103548954368679936</ref>}} {{History||v0.2.0|[[File:Camera BE2.png|50px]] [[File:Music Disc Blocks JE1 BE1.png|32px]] Added cameras |Changed item and tripod textures. |To use a camera, equip it in the [[player]]'s hand, then look in the direction the player wants the picture to be taken.

Bark blocks

See also: Log

File:Oak Bark.pngFile:Birch Bark.pngFile:Spruce Bark.pngFile:Jungle Bark.pngFile:Acacia Bark.pngFile:Dark Oak Bark.png

Wood blocks with data values 12 through 15 have the bark texture on all 6 sides. These are not found naturally and cannot be crafted‌. When obtained in the inventory and placed, they will act like a normal wood block, placing with their axis corresponding to the face of the block clicked. They can be obtained using the /give command. They can be placed, but just like as normal (depending on the wood) log.

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. === Crafting === {{Crafting |B1=Redstone Torch |A2=Redstone Torch |B2=Nether Quartz |C2=Redstone Torch |A3=Stone |B3=Stone |C3=Stone |Output= Redstone Comparator |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|<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.

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.

The chance of catching treasure increases with the [[Luck of the Sea]] enchantment. === Trading === Master-level librarian [[villagers]] offer to sell a name tag for 20 [[emerald]]s as one of their available trades. == Usage == To use a name tag, it must first be renamed with an [[anvil]], costing 1 [[experience]] level. If it is not renamed, it has no effect when used on a mob. After the name tag is renamed, the player can {{control|use}} it on a mob to give it the name given to the name tag from the anvil. Mobs and name tags can be renamed any number of times. Name tags with the same name are stackable. Once a mob is named, it keeps its name, and the name tag is consumed. When a mob is named, it is excluded from the mob cap count. Effects on various mobs: * A named [[silverfish]] that goes into a block appears to lose its name because it is replaced by a newly generated unnamed silverfish when the block is broken. * A baby (animal or villager) keeps its name when becoming an adult. ** A named [[villager]] keeps its name when transformed into a [[Zombie Villager|zombie villager]]. ** A named zombie villager keeps its name when cured. * [[Wandering Trader|Wandering trader]]s still despawn even if they are named, or in a [[minecart]] or [[boat]]. * A named [[wither]]'s boss bar displays its name instead of "Wither". * Naming an [[ender dragon]] with commands also displays the name in the boss bar. === Limitations === Any mob can be named except for the [[ender dragon]] and [[player]]s. A name tag can rename an [[armor stand]], though it does not show the nameplate above its head until <code>CustomNameVisible:1b</code> is set as an extra step. {{control|Using|use}} a name tag on a villager renames the villager instead of opening the trading interface. A saddled pig is renamed instead of being ridden. Using a name tag on any other mob that can be interacted with performs the {{control|use}} action instead of being named. These mobs can be renamed if the player uses the name tag while crouching or standing in a [[nether portal]] because the portal suppresses the {{control|use}} action. Once a name tag is used on a mob, it is impossible to remove the name of that mob without the use of commands or external modifications. === Behavior === Renamed mobs have their name displayed over their head in the same fashion as a mob named through a renamed [[spawn egg]]. Their names can be seen only if they are aimed at from four or fewer blocks away. Mobs that are named using the name tag never despawn in the world, similar to tamed mobs.<ref>{{tweet|dinnerbone|327485109940916226}}</ref> The exceptions are [[wandering trader]]s or if the mob is hostile and the difficulty is switched to "[[Peaceful]]", causing any hostile mobs or any named hostile mobs to despawn immediately. If a renamed mob kills a player, the custom name is used in the death message in place of the mob type name. For instance, if a vindicator named "Johnny" kills a player, the death message is "Player was slain by Johnny". A renamed [[wither]] also has a renamed health bar, and the boss bar doesn't regenerate{{verify}}. === Easter eggs === * Any mob that receives the name "[[Easter eggs#Upside-down mobs|Dinnerbone]]" or "[[Easter eggs#Upside-down mobs|Grumm]]" is rendered upside down. This even includes the player in early versions of Bedrock Edition if the username is set to either of these and you are not signed into Xbox Live. * Naming a [[sheep]] "[[Easter eggs#Jeb sheep|jeb_]]" causes its wool to fade between the dye colors, producing a rainbow effect. The [[wool]] that drops when the sheep is [[shear]]ed or killed is the original color of the sheep before the sheep was named. * Naming a [[rabbit]] "[[Rabbit#Toast|Toast]]" causes it to have a special memorial skin of user xyzen420's girlfriend's [http://www.reddit.com/r/minecraftsuggestions/comments/27hjog/to_themogminer_my_bunny_is_missing_please_help_me/ missing rabbit]. * Naming a [[vindicator]] "Johnny" causes it to be aggressive and attack all [[mob]]s including the wither (except [[ghast]]s and other [[illager]]s). The hostility even extends to [[Ravager|ravagers]] in [[Java Edition|''Java Edition'']], as the "Johnny" vindicator can also attack the ravager while it's riding it. == Data values == === ID === {{edition|java}}: {{ID table |edition=java |showforms=y |generatetranslationkeys=y |displayname=Name Tag |spritetype=item |nameid=name_tag |form=item |foot=1}} {{edition|bedrock}}: {{ID table |edition=bedrock |shownumericids=y |showforms=y |notshowbeitemforms=y |generatetranslationkeys=y |displayname=Name Tag |spritetype=item |nameid=name_tag |id=548 |form=item |foot=1}} == History == {{History|java}} {{History||1.6.1|snap=13w16b|[[File:Name Tag JE1 BE1.png|32px]] Added name tags.

Old wood slabs

Before unique slabs corresponding to different wooden planks species were added, oak wooden slabs were treated like other stone-type slabs. They required a pickaxe to break, had a blast resistance greater than normal planks, and had stone sounds. They are still obtainable in worlds which had them in it previously. They are tagged as Wooden Slab, reflecting on the fact oak was the only wood species in plank form. It has a missing texture in the inventory.‌ In 1.13 snapshot 17w47a, this block is now called "Petrified Oak Slab" and it is available in the creative inventory and has a model.‌

Mobs

Giant

Main article: Giant

Giants are an unused mob added in Indev. They appear to be a giant zombie. Giants currently have no AI and they cannot spawn naturally because the game requires the light level to be both greater than 11 and less than 8. They can be summoned using the /summon giant command.

The Killer Bunny

Main article: Rabbit

The killer bunny is a variant of the rabbit that is hostile to all players and dogs. Its fur is pure white with blood-red eyes that are horizontal, compared to a normal rabbit's vertical eyes.

On peaceful difficulty, the killer bunny will not despawn, despite its hostile nature. It will still attack wolves and pet dogs. When it was originally added in snapshots of 1.8, it spawned as a rare type of rabbit, but it was removed before the final release.

The Killer Bunny can only be spawned with the /summon rabbit ~ ~ ~ {RabbitType:99} command.

Zombie Horse

Main article: Horse

Zombie Horses are a variant of horses that were added in 1.6, along with normal and skeleton horses. There is a zombie horse spawn egg available only in creative, but they remain unused in survival.

In addition to spawn eggs, zombie horses can be spawned with the /summon zombie_horse command.

Illusioner

Main article: Illusioner

The Illusioner is an unused Illager that was added in 1.12. They will attack players, villagers, and iron golems within a 12 blocks range. It will attack with its spells, and with its bow.

The illusioner has two spells: a spell that blinds its opponent, and a spell that summons duplicates and makes the illusioner invisible.

The illusioner has a face that is just like the face of a vindicator.

Illusioners can only be spawned with the /summon illusion_illager command.

Potions

Main article: Potions

The uncraftable potion is a potion added in the 1.9 snapshot 15w44b with no effect that is unobtainable in survival. It is also available in splash potion and lingering potion forms, as well as for tipped arrows. It serves as a placeholder for potions that have missing or invalid potion-effect tags, which they automatically default to.

It can be obtained using the following command: /give @p minecraft:potion 1 0 {Potion:"minecraft:empty"}.

Icon	Name	DV
	Uncraftable Potion	373
	Uncraftable Splash Potion	438
	Uncraftable Lingering Potion	440
	Uncraftable Tipped Arrow	441

There are also potions that cannot be brewed, and give you status effects not intended to be received by potions; e.g. Wither, Nausea. Again, these can only be obtained through custom potions.

Status effects

Main article: Status effects

Various status effects remain unused in the game. They can be obtained using /effect or potion NBT data, but have no way of being obtained other than that.

Bad Luck

Bad Luck reduces chances of high-quality loot.

Blindness

Blindness is a status effect which creates thick black fog around the player and prevents them from sprinting. As of snapshot 17w16a for 1.12, this effect can be obtained from an illusioner, though those mobs are also unused.

Health Boost

During the 1.6 snapshots, the health boost status effect was added. It boosted the player's hearts for a temporary time. It could be obtained from eating a golden apple.

In the next main snapshot, golden apples give the player absorption instead of health boost, but the effect was still left in the game.

In 1.9, the developers gave the Health Boost effect a new texture from its original golden heart texture, despite the fact that it is still not in use.

Saturation

Saturation is a status effect added in the 1.6.1 pre-release. It causes the hunger bar to refill by 1 () each tick.

Biomes

Main article: Biome

The following biomes remain unused since 13w36a and 18w08b. While they do not naturally generate in default worlds, they can be accessed using the Buffet & Customized world type.

Biome ID	Name and Features	Description	Images
20	Extreme Hills Edge Temperature: 0.2 Grass, Dirt, Stone, Pigs, Sheep, Cows, Wolves, Spruce trees, Oak trees, Snow (occasionally)	Similar to the jungle edge sub-biome, this sub-biome generates exclusively at the edge of extreme hills biomes (or any variant).	File:Extreme Hills Edge.png
	Warm Deep Ocean Temperature: 0.1 Puffer fish mobs, Tropical fish mobs, Warm underwater ruins, Sand, Kelp, Sea grass, Ocean monuments, Guardians, Elder guardians	Similar to warm ocean biomes, but twice as deep. Because they are a deep ocean variant, they can generate ocean monuments, resulting in the spawning of guardians, elder guardians, prismarine, and sponges.	File:Warm Deep Ocean.png

Sounds

Audio loops

Loops were unused sounds, found in the game files, and were possibly meant for when the player is in a specific type of location (i.e., in caves, woods, the ocean and beside a waterfall).

They were found in .minecraft/resources/sound/loops/, and could be converted to reveal four loops, of birds chirping, cave chimes, ocean and waterfall noises.

Resources

Various resources located in the game's assets files that remain unused.

Angry villager head

File:AngryVillager.png

See also: Villager

In the particles sheet, there is an angry villager head which remains unused.

chunkinfo‌

As of 1.8 (14w30a), the file en_us.lang contains translation strings for a /chunkinfo command which does not exist in game. The following keys exist:

commands.chunkinfo.usage=/chunkinfo [<x> <y> <z>]
commands.chunkinfo.location=Chunk location: (%s, %s, %s)
commands.chunkinfo.noChunk=No chunk found at chunk position %s, %s, %s
commands.chunkinfo.notEmpty=Chunk is not empty.
commands.chunkinfo.empty=Chunk is empty.
commands.chunkinfo.notCompiled=Chunk is not compiled.
commands.chunkinfo.compiled=Chunk is compiled.
commands.chunkinfo.hasNoRenderableLayers=Chunk has no renderable layers.
commands.chunkinfo.hasLayers=Chunk has layers: %s
commands.chunkinfo.isEmpty=Chunk has empty layers: %s
commands.chunkinfo.vertices=%s layer's buffer contains %s vertices
commands.chunkinfo.data=First 64 vertices are: %s

It is unknown if this command is used by Mojang for development or was simply a dropped feature.

Old conduit particle

See Conduit#History.

Paeonia‌

File:Paeonia texture.png

Main article: Flower

Paeonias are unimplemented flowers that were replaced by the two-block-tall peonies.

There was only one screenshot of the block released by Jeb. Its texture file can still be found; it is named flower_paeonia.png.

Purple arrow

File:PurpleArrow.png

See also: Arrow § History

Purple arrows were shot by skeletons in Survival Test and acted the same as regular arrows, and used a texture on the same sheet as the normal arrows, but the texture is not currently in use.

In 1.9, a new texture was added for arrows, causing the original arrow texture including the purple arrows to be entirely unused.

Ruby

See also: Emerald

File:Ruby (Item).png

On May 21, 2012, Jeb released a screenshot of himself testing the trading system. At this time, what would become emerald ore in 1.3.1 was ruby ore. The previous ruby texture remains in the ruby.png file. It is unknown if the texture will ever be used. Dinnerbone stated in a forum post that they went with emeralds instead of rubies at the last minute because he is color-blind and he had a hard time spotting the difference between ruby ore and redstone ore. The names "Ruby Ore" and "Ruby" are still in the .lang files.

Villager speech bubble

The villager speech bubble is an image that was added along with the villager.png file in the jar when the trading system was added. It showed a trade, where raw chicken could be sold to villagers for another raw chicken. Both raw chickens have the old texture. During an interview about villagers, Jeb offered a possible explanation: "We did some experiments with thoughts bubbles, but it didn't look good. So in the end, after I’d been lead on Minecraft for a year, we just decided to add an interface instead."

Since 1.9, the texture has been partially overwritten by the selection arrows.
