Minecraft:Java Edition unused features

Template:Unobtainable Since the beginning of Minecraft: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.

This article documents only unused features that are currently in the game. See Minecraft:Java Edition removed features for features previously in the game that are no longer available.

Blocks

Unobtainable block states

Block	State	Effect
Template:BlockLink	cracked: true	When this is set to true, the decorated pot always drops its sherds or bricks regardless of how it is broken.
Template:BlockLink	short: true	Piston heads that have this set to true appear shorter by 4 pixels. This state itself does not seem to be used for the piston extension/retraction animation, but its model is used during the animation.
Template:BlockLink	unstable: true	Breaking TNT that has this set to true does the same thing as lighting it, eventually causing an explosion.

Unobtainable block state combinations

Certain blocks have certain combinations of block states that cannot be encountered in usual Survival gameplay, and instead require using Minecraft:commands, the Minecraft:debug stick, a Minecraft:debug world, or certain glitches, many version-specific. Some may also be able to be created via update suppression methods, or be able to be created in older game versions and updated forward. As these are impossible to encounter, mapmakers may be able to use some of them as blank slates and remodel these using model files for custom blocks as these cannot be encountered in any gameplay. These states are generally fragile.

	falling: true level:1-7

Entities

Giant

File:Zombie.png

Giants are an unused Minecraft:mob added in Minecraft:Indev. They appear to be a giant Minecraft:zombie. Giants have no movement AI, therefore they are unable to walk around. They cannot spawn naturally because the game requires the light level to be both greater than 11 and less than 8 and those conditions cannot be met in vanilla. This makes them impossible to spawn via Minecraft:monster spawners.

Giants can be summoned only by using the Template:Cmd command.

In the 18w50a snapshot, the giant has an AI and is able to attack the player. The AI was removed in the 19w03a snapshot.

In the 2020 April Fools' snapshot, the giant is able to naturally spawn on occasion in custom dimensions.

In the 2024 April Fools' snapshot, a retextured giant can spawn in the colloseum, in the Minecraft:Potato dimension. It is a part of the boss fight with Minecraft:mega spud, and has an AI.

The killer bunny

File:Killer Bunny.png

A variant of the rabbit that is hostile toward all wolves, foxes, and players. Its fur is pure white with blood-red eyes that are horizontal, compared to a normal Minecraft:rabbit's vertical eyes.

If the killer bunny finds any player within a 16-block radius, it hops quickly toward the player, much faster than a normal rabbit. It moves in a style similar to that of a Minecraft:spider. Once it closes in, it lunges at the player, dealing a fair amount of damage. If the player strikes at the killer bunny, it runs away for a brief moment, then returns to lunging at the player. Killer rabbits are also immune to the Minecraft:Thorns enchantment.

If it cannot find a player, the killer bunny actively seeks out and attacks any Minecraft:wolves as well, including tamed wolves. These wolves, in turn, turn hostile and attack the killer bunny, leading to a vicious fight.

On Peaceful difficulty, the killer bunny does not despawn, despite its hostile nature. It still attacks wolves (both tamed and untamed).

The killer bunny can be spawned only with the Template:Cmd command.

Illusioner

File:Illusioner.png

An unused Minecraft:illager that was added in Minecraft:Java Edition 1.12. Like other illagers, they attack Minecraft:players, Minecraft:villagers, Minecraft:wandering traders and Minecraft:iron golems within a 12 blocks range. It attacks with its spells, and with its Minecraft:bow.

It 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 an Minecraft:evoker, formerly of a Minecraft:vindicator.

Illusioners can be spawned only with the Template:Cmd command.

Minecart with monster spawner

File:Minecart with Spawner JE2.png

A combination of a Minecraft:minecart and a Minecraft:monster spawner. Cannot be obtained as an item in the inventory, and can be placed only by using the Template:Cmd Minecraft:command.

The monster spawner inside the minecart acts the same way as normal monster spawners, and the mob being spawned can be changed with /data modify.

When killed, minecarts with monster spawners drop 1 Template:ItemLink.

Unused paintings

In v0.5.0 alpha, with the addition of paintings to Pocket Edition, four unused 32×32 paintings were present in Minecraft:kz.png that remained unused. They were also added to Java Edition in snapshot Minecraft:22w16a. They can be summoned by Minecraft:commands (such as Template:Cmd) or through a Minecraft:data pack. They can also be found in the Operator Utilities tab in the Minecraft:Creative inventory.

According to Minecraft:Helen Zbihlyj<ref>https://reddit.com/r/Minecraft/comments/u8hpnx/thoughts_on_the_new_paintings/i5olue6/?context=3 (archived)</ref>, these paintings were originally added "as part of a Pocket Edition promo map" (no footage found) that was planned to be a part of Minecraft:Pocket Edition promotion at Minecraft:MINECON 2012 or 2013 and have never been used in game. The artist of these paintings remains unknown.

Status effects

Template:MainTemplate:See also Various status effects remain unused in the game. They can be obtained only by using Template:Cmd or Minecraft:potion NBT data.

Template:EffectLink

Luck increases the chance of high-quality loot. The Luck effect can be obtained from potions of luck, splash potions of luck, lingering potions of luck and arrows of luck; These items require commands to be obtained.

From snapshot Minecraft:19w13a to Minecraft:1.14 Pre-Release 1, arrows of luck could be obtained from fletcher villagers when the player had the Minecraft:Hero of the Village status effect.

Template:EffectLink

Bad Luck is the opposite of Luck; it reduces the chances of high-quality loot. Bad Luck cannot be obtained from potions; It can only be obtained via Template:Cmd.

Template:EffectLink

Added in Minecraft:Java Edition 1.6.1 snapshot Minecraft:13w23b. The effect boosted the Minecraft:player's hearts for the duration of the effect. It could be obtained from eating a Minecraft:golden apple. Since snapshot Minecraft:13w24b, golden apples give the player Absorption instead of Health Boost, but the effect was left in the game.

In Minecraft:Java Edition 1.9 the Health Boost effect's texture was changed to be distinct from Absorption and was again remade in Minecraft:Java Edition 1.14 by Minecraft:Jasper Boerstra (commonly known as Jappa).

Developer tools

Template:MainThere is code for numerous development tools. They remain unused in the latest version of Java Edition but can be enabled with the help of mods.

Resources

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

Map icons

Some extra icons for Minecraft:maps. The white and green arrows are the only ones used normally, though the colored arrows are used for multiplayer Template:In.

Mob attacks

Skeleton melee attack

Minecraft:Skeletons normally wield bows, but if one were to spawn in a skeleton with a Minecraft:sword, the skeleton can use it like a normal weapon.

Wither skeleton ranged attack

If a Minecraft:wither skeleton is spawned with a bow, it can use it as intended, except the arrow is always on fire, even without lava or enchantments.
