Slimes are bouncy cube-shaped hostile mobs that spawn in the swamp and, occasionally, deep underground in particular chunks called slime chunks.

Spawning [ edit ]

Slimes spawn in the Overworld in specific "slime chunks" below layer 40, regardless of light levels. They can also spawn in swamp biomes between layers 50 and 70 in light levels of 7 or less.

Only sizes 1, 2, and 4 spawn naturally. With use of /summon , slimes can potentially range from size 1 to 256 (NBT Size tag 0–255).

Slimes do not spawn within 24 blocks (spherical) of any player, despawn over time if no player is within 32 blocks, and despawn instantly if no player is within 128 blocks.

Slimes require two vertical, transparent blocks (such as air, signs, or torches, but excluding Redstone-related items[more information needed]) to spawn in, with an opaque block underneath. The space they spawn in must also be clear of solid obstructions and liquids.[more information needed] Big slimes require a 3×2.5×3 space to spawn, medium slimes require a 3×2×3 space, and small slimes require a 1×2×1 space (or 1×1×1 if the upper block is not opaque).[1]

Slime size is affected by regional difficulty: chances range from 33% for each size at the low difficulty to 16% small, 33% medium, and 50% big with higher difficulty.

Swamps [ edit ]

In swamps, slimes may spawn at night between the heights of 50 and 70 when the provided light level is 7 or less. They spawn most often on a full moon, and never on a new moon. Slimes spawn in the normal swamp, but not in its variant, swamp hills.

More precisely, the game checks two factors:

If the light level is equal to or less than a random integer (from 0 to 7) If the fraction of the moon that is bright is greater than a random number (from 0 to 1)

If these conditions are met and the altitude is acceptable, there is a 50% chance of spawning a slime.

Slimes spawn throughout the world (except mushroom islands) below level Y=40 regardless of light level, but only in certain chunks; 1⁄ 10 of all chunks.

Java Edition [ edit ]

In Java Edition, these "slime chunks" are determined pseudo-randomly by combining their chunk coordinates with the seed of the world:

import java.util.Random ; public class checkSlimechunk { public static void main ( String args []) { // the seed from /seed as a 64bit long literal long seed = 12345L ; int xPosition = 123 ; int zPosition = 456 ; Random rnd = new Random ( seed + ( int ) ( xPosition * xPosition * 0x4c1906 ) + ( int ) ( xPosition * 0x5ac0db ) + ( int ) ( zPosition * zPosition ) * 0x4307a7L + ( int ) ( zPosition * 0x5f24f ) ^ 0x3ad8025fL ); System . out . println ( rnd . nextInt ( 10 ) == 0 ); } }

That is, using the chunk coordinates to help generate a seed, a random number between 0 and 9 inclusive is generated. If that number is 0, the chunk can spawn slimes. To convert world coordinates to chunk coordinates, divide by 16 and round down. Note that xPosition and zPosition are 32-bit integers ( int s).

Bedrock Edition [ edit ]

The slime chunk algorithm in Bedrock Edition is different from in Java Edition. The algorithm doesn't depend on the world seed, thus the chunks that slimes can naturally spawn in inhabit the same coordinates for every world.[2]

Drops [ edit ]

If a slime's size is 1, it drops 0-2 slimeballs. This can be increased by 1 per level of Looting, for a maximum of 5 slimeballs.

Slimes also drop experience points equal to their size. 1, 2 or 4

Behavior [ edit ]

Dripping slime.

Slimes move by hopping, which they do every 10 to 30 ticks (1⁄ 2 to 1 1⁄ 2 seconds), and can swim in water and climb ladders and scaffolding. Unlike other mobs, slimes continue moving when no players are nearby. Their exact routine is as follows:

The slime searches for a player (or, failing that, an iron golem or snow golem) within 16 blocks (spherical) distance.

If no target is found, the slime waits 10 to 30 ticks ( 1 ⁄ 2 to 1 1 ⁄ 2 seconds). Then it changes direction by a random amount up to 57.26° (1 radian) left or right, jump forward, and repeat the process.

⁄ to 1 ⁄ seconds). Then it changes direction by a random amount up to 57.26° (1 radian) left or right, jump forward, and repeat the process. If a target is found, the delay before jumping is 1⁄ 3 as long (3 to 10 ticks), and the slime's direction is set directly toward the target before jumping.

A slime's maximum health is equal to its size squared, and its dimensions are 0.51 blocks times its size in each dimension. When a slime attacks, it deals damage equal to its size, except for size 1 (smallest) slimes. Small slimes do not prevent sleeping.

A slime's jump distance also depends on its size; a slime jumps a distance slightly farther than its length. When landing, several slime particles 1⁄ 8 its size appear.

When a slime dies and the slime's size is larger than 1, it dies and spawns 2-4 new slimes equivalent to its size divided by 2, rounding down.

A slime's attack speed is twice that of other melee-combat mobs. This speed is noticeable when the slime has the player cornered at a wall. Mobs like zombies and spiders attack at a rate of one hit per second, while slimes attack at a rate of two hits per second. Slimes damage all players and iron golems‌[JE only] they collide with, unlike other mobs that damage only those targets they specifically attack.

Slimes in water attempt to swim to the surface if possible. If forced to stay submerged, they eventually drown, splitting into smaller slimes that drown and finally drop slimeballs.

Entity data [ edit ]

Slimes have entity data associated with them that contains various properties.

Entity data Tags common to all entities see Template:Nbt inherit/entity/template Tags common to all mobs see Template:Nbt inherit/mob/template Size : The size of the slime. Note that this value is zero-based, so 0 is the smallest slime, 1 is the next larger, etc. The sizes that spawn naturally are 0, 1, and 3. wasOnGround : 1 or 0 (true/false) - true if the slime is touching the ground.

Trivia [ edit ]

A player can earn a maximum of 28 experience points from killing one slime and all the slimes that split from it: 4 experience from the largest, 8 experience from the 4 it splits into, and 16 experience from the 4 each of those split into.

A named large slime that dies produces smaller slimes with the same name.

In Java Edition , with commands, the size of slimes can be customized. Sizes go from 1 up to 256; the size-256 slime is the largest of any mob in the game, bigger than the ender dragon.

, with commands, the size of slimes can be customized. Sizes go from 1 up to 256; the size-256 slime is the largest of any mob in the game, bigger than the ender dragon. Small slimes are the weakest of all mobs; they have only 1 health point and deal no damage, despite being a hostile mob.

Because a slime's movement speed is tied to its size it becomes impossible for the player to outrun a size 8 slime on flat ground without potion effects.

When a slime is searching for nearby players to attack them or check to see if it should despawn, it checks not from its outer edges, but instead from a point in the center of its hitbox on the x and z-axis and the bottom of its y-axis. This means when a slime is spawned with a huge custom size it can be right in front of the player and be completely passive, it may even despawn despite its outer edge is less than a block away if the slime is large enough.

Small and medium slimes are a reference to "Goople" and "Oozle" from the game "Amorphous+"
