Slime in Minecraft
Slimes are bouncy, cube-shaped hostile monsters that spawn in certain sections deep down or at night in swamp biomes. Slimes spawn in distinct “slime chunks” below layer 40 in the Overworld, independent of light levels. They can also spawn in marsh biomes with light levels of 7 or less between layers 50 and 70, with these layers being closer to the surface. Natural spawning occurs in only sizes 1, 2, and 4 (NBT Size tag values 0, 1 and 3). Slimes do not spawn within 24 blocks (spherical) of any player, despawn over time if no player is within 32 blocks, and despawn instantaneously if no player is inside the despawn radius, just like most other hostile creatures (128 blocks in Java Edition, 44 to 128 blocks in Bedrock Edition depending on simulation distance[verify]) Slime in Minecraft .
To spawn, a slime requires around 3×02.1×3 open area. There must be no solid or liquid impediments in the slime’s spawning region. The game checks for the space needed of a huge slime when a slime tries to spawn, and the size is calculated subsequently. As a result, because giant slimes are slightly taller than 2 blocks, no slimes of any size may spawn in 2-block-high locations. Also, because huge slimes are slightly wider than 2 blocks and monsters spawn in the middle of a block, any block inside the 32.1×3 region, even as thin as a glass window, can prevent any slime from spawning.
Slime size is regulated by regional difficulty: odds vary from 33% for each size at low difficulty to 16% tiny, 33% medium, and 50% giant at greater difficulty.
Swamps
Slimes may spawn at night between the heights of 50 and 70 in marshes and mangrove swamps [upcoming: 1.19] when the given light level is 7 or below. They spawn most frequently on full moons and never on new moons. Slimes spawn in the standard swamp but not in any of the varieties.
More specifically, the game examines two factors:
If the light intensity equals or falls below a random integer (from 0 to 7)
If the proportion of the moon that is illuminated exceeds a certain threshold (from 0 to 1)
If these parameters are satisfied and the height is suitable, a slime has a 50% probability of spawning.
“Slime chunks”
Slimes spawn in all chunks (excluding mushroom fields) below level Y=40, independent of light level, but only in 110 of them.
Java Version
These “slime chunks” are determined pseudo-randomly in Java Edition by mixing their chunk coordinates with the world seed:
That is, a random number between 0 and 9 inclusive is created using the chunk coordinates as a seed. If that value is 0, the chunk is capable of spawning slimes. Divide global coordinates by 16 and round down to chunk coordinates. It should be noted that xPosition and zPosition are both 32-bit integers (ints).
The Bedrock Edition
Bedrock Edition’s slime chunk algorithm differs from that of Java Edition. Because the technique does not rely on the world seed, the chunks that slimes can naturally spawn in occupy the same coordinates in every world.
Drop
If a slime’s size is 1, it will drop 0-2 slimeballs. This may be increased by one at each level of Looting, up to a maximum of five slimeballs.
Slimes drop experience points proportionate to their size: 4 for giant slimes, 2 for medium slimes, and 1 for little slimes. Because slimes divide into 2-4 smaller slimes when they die, killing one slime and all the slimes that split from it can result in a maximum of 28 experience points.
Behavior
Slimes move by hopping every 10 to 30 ticks (12 to 12 seconds), and they can swim and climb ladders and scaffolds. Slimes, unlike other mobs, continue to move even when no players are around. The following is their precise routine:
Within 16 blocks (spherical) distance, the slime looks for a person (or, failing that, an iron golem or snow golem).
If no target is located, the slime will wait for 10 to 30 ticks (12 to 12 seconds). Then it jumps forward and repeats the procedure, changing direction by a random amount up to 57.26° (1 radian) left or right.
If a target is detected, the delay before leaping is 13 times as lengthy (3 to 10 ticks), and the slime’s direction before jumping is set directly toward the target.
The maximum health of a slime is equal to its size squared, and its dimensions are 0.51 blocks in each dimension. When a slime strikes, it does damage proportionate to its size, with the exception of size 1 (tiniest) slimes, which inflict no damage and do not prevent sleeping. Because little slimes still have a hostile AI, they assault the player incessantly.
A slime’s leap distance is likewise determined by its size; a slime jumps somewhat farther than its length. Several slime particles 18 its size emerge as it lands.
When a slime greater than one dies, it produces 2-4 new slimes according to its size divided by 2, rounded down. When a slime with a name tag dies, it generates little slimes with the same name.
The attack speed of a slime is double that of regular melee-combat creatures.
This speed is visible when the slime has trapped the player against a wall. Mobs such as zombies and spiders attack at one hit per second, whereas slimes attack at two hits per second. Slimes inflict harm on all players and iron golems [JE only] they collide with, as opposed to other monsters, which inflict damage exclusively on the creatures they expressly assault.
Slimes in water try to swim to the surface if they can. If they are forced to stay underwater, they will ultimately drown, separating into smaller slimes that will also drown and drop slimeballs.
The size of slimes in Java Edition may be changed using commands. Sizes range from 1 to 256, with the size-256 slime being the biggest mob in the game, larger than the ender dragon.
Because a slime’s movement speed is proportional to its size, it is impossible for the player to outrun a size 8 slime on level terrain without the use of a potion.
When a slime looks for nearby targets or determines whether to despawn, it checks from a position in the middle of its hitbox on the x and z axes, as well as the bottom of its y axis. As a result, a large enough custom-size slime can be directly in front of the player and be perfectly passive, and it may even despawn if the slime is large enough.
Green-colored Slimes may also be seen in Notch’s Minicraft, a 2D Minecraft-inspired game.
When a player enters a slime, they may see the slime itself inside a slime block.
When the player looks at the corner of a glass block, the slime within the slime block vanishes, giving the impression that the slime block is alive.
