A mob is an AI-driven game entity resembling a living creature. The term "mob" is short for "mobile entity".[1] All mobs can be attacked and hurt (from falling, attacked by a player or another mob, falling into the void, etc.), and have some form of voluntary movement. Different types of mobs often have unique AI and loot.

Spawning

Main article: Spawn cycle

Most monsters are found in dark areas such as caves, while most animals are found commonly in bright light levels. Most other mobs are also found in different biomes/structures.

Mobs spawn in various ways. Most mobs spawn naturally, depending on the light level, biome, and their surroundings. For example, most animals are found in bright areas on the surface, whilst hostile monsters are commonly found in the dark (whether if it’s a cave, dungeon, mansion or at night). Animals usually spawn upon chunk generation, while hostile monsters spawn and despawn in certain radii around the player. Some mobs including passive and neutral animals, and even hoglins have the ability to be bred by the player, creating offspring. Villagers also breed randomly depending on the time of day and the number of beds (though they can’t be directly bred by the player). Most mobs never spawn on transparent blocks, in water (except fish, dolphins, turtles, and other aquatic creatures), in lava (except for striders), on bedrock, or on blocks less than a full block tall (such as slabs placed on the bottom half). The exception is monster spawners, from which monsters can spawn naturally on any block including air.

Some mobs (like the snow golem and the wither) require that the player "construct" them before being able to spawn. The iron golem can spawn naturally and can also be constructed. The ender dragon can be respawned with four end crystals.

Players can also spawn mobs easily by using a spawn eggs in Creative mode, or the command.

Despawning

Main article: Spawn&#;§&#;Despawning

Many mobs despawn (cease to exist) after a certain amount of time if far enough from the player. In Java Edition, most passive mobs do not despawn, while most monsters do. In Bedrock Edition, almost all mobs despawn.

Behavior

Mobs are affected by the environment in the same ways as the player: they are subject to physics, and they can be hurt by the same things that harm the player (catching on fire, falling, drowning, attacked by weapons, /kill command, etc.). Some mobs may be resistant or immune to certain hazards, such as Nether mobs, which are immune to fire. All aquatic mobs except dolphins are immune to drowning. Mobs can ride minecarts and other mobs can climb up ladders. When mobs are killed, they turn to dust and drop items that may be useful resources. Each type of mob in Minecraft has a certain AI (artificial intelligence) system with different behaviors and mechanics. Mobs ordinarily wander around at random if there is a player nearby and usually avoid walking off blocks high enough to cause falling damage. Many mobs have an advanced pathfinding system that allows them to navigate through obstacles to get to a desired object or destination. Passive mobs flee in random directions after being hurt, while hostile mobs face and chase/attack the player as soon as the player comes close. Neutral mobs remain neutral until a player or mob provokes it (usually by attacking), at which point the neutral mob becomes hostile toward and attack the entity that hit it. Most mobs are aware of players within 16 blocks of them, but some can see farther. Conversely, most mobs can be heard by players up to 16 blocks (spherical) away.

Most mobs cannot see through most solid blocks, including semi-transparent blocks such as ice, glass, tall grass, or glass panes. Mobs do not attempt to walk on rail tracks unless pushed onto the rails by other mobs.

List of mobs

Mobs are listed and classified by their nature from the player's perspective. For more details on a particular mob, click on them to view their individual page.

Passive mobs

Passive mobs are harmless mobs (except for pufferfish) that do not attempt to attack the player, even when provoked or attacked. Most of them can be bred or tamed.

  1. abcThis mob can trust the player.
  2. abcdeThis mob can be tamed by the player.
  3. ↑The skeleton horse is passive after the rider is killed.

Neutral mobs

Neutral mobs are sometimes passive and sometimes hostile toward the player. All of these mobs (except goats) are provoked when player attack it first. Some mobs may also be naturally hostile with provocation, and some mobs also have some additional way to be provoked.

  1. abcdAll nearby mobs of the same type become hostile when a single one is provoked, unless the player kills it in one hit.
  2. ↑In addition to attacking when provoked, bees become aggravated when a nearby beehive is broken. Bees who claim a beehive become angry when honey is harvested unless a campfire is placed beneath the beehive. A bee can sting the player only once, and ceases to attack thereafter although the bee's hostile texture remains. In addition, they become passive again after a short time.
  3. abThis mob is naturally hostile when the light level is 7 or less; meaning they are naturally hostile whenever they spawn. They become neutral when in a light level higher than 7, although they continue attacking any players they were attacking before being in this light level.
  4. abcdeIn Java Edition, this mob is associated with the advancements Monster Hunter and Monsters Hunted.
  5. ↑In addition to attacking when provoked, an endermen becomes hostile when a player looks directly at its head.
  6. ↑The goat is the only neutral mob that is not provoked by attacking, but rather is randomly provoked to attack other mobs.
  7. ↑In addition to attacking when provoked, iron golems attack players with low village popularity.
  8. abThis mob becomes neutral after attacking the player a single time.
  9. abcThis mob can be tamed by the player.
  10. ↑Most panda personalities attack the player once. Aggressive pandas become hostile when provoked.
  11. ↑Baby piglins are naturally passive and adult piglins are naturally hostile, but if the player is wearing at least one piece of gold armor, then the adult piglin becomes neutral. In its neutral state, if one piglin or piglin brute is attacked, or if the player opens or breaks any nearby container, or breaks golden blocks, all nearby piglins become hostile, even if the player is wearing gold armor.
  12. ↑Like all mobs, adult polar bears are passive on Peaceful difficulty. When the player is near a cub, the parent polar bear becomes hostile toward the player, although it seldom happens in Easy difficulty and baby polar bears are naturally passive. When a cub is attacked, nearby polar bears become hostile toward the attacker.

Hostile mobs

Hostile mobs are dangerous, aggressive mobs that always attack the player within their respective detection ranges.

  1. ↑Despite being referred to as a boss by updates, the elder guardian doesn't have the same features as a boss mob, although it is stronger than regular mobs.
  2. ↑If a baby hoglin is attacked by the player, it temporarily becomes neutral, fleeing the player after getting attacked.
  3. ↑If a pillager breaks its crossbow, it becomes passive.&#;[JE only]

Compound mobs

Compound mobs or jockeys are naturally spawned mobs riding another mob that also follow the spawning patterns of the bottom mob. The mob on the top controls the mob on the bottom, overwriting its AI and speed attributes. Jockeys cannot be separated unless one of the mobs is killed. The mobs follow their normal rules of behavior.

Boss mobs

Boss mobs are special hostile mobs that are distinctly more dangerous and tougher than other mobs. They do not spawn randomly, and are confronted intentionally. All of them also have a boss bar featuring their name and health. Boss mobs provide unique challenges but also equivalent rewards. Some players also consider elder guardians, skeleton horsemen, illusioners, ravagers, evokers, and piglin brutes as mini bosses.

Unused mobs

Only contains a few mobs that never spawn naturally in-game as they can only be summoned with the command though the zombie horse can be spawned in with a spawn egg.

Education Edition mobs

Passive mobs that are exclusive to the Education Edition, and Bedrock Edition under the Education Edition toggle.

Removed mobs

Removed mobs no longer exist in current versions of the game.

Joke mobs

Mobs that were added as a joke for April Fools' Day in Java Edition.

Unimplemented mobs

See also: Java Edition mentioned features&#;§&#;Mobs

Mobs that were announced by Mojang as confirmed, mentioned or potential future additions, but either got replaced by other mobs or scrapped.

These mobs either:

  • Were said to not be added in a future update (the mobs that lost the MINECON Earth mob vote)
  • Were said to have a possibility of being added in a future update (the mobs that that lost the Minecraft Live mob vote)[2]
  • Are not known to be under consideration for a future update (the Red Dragon and the mobs that lost the China Edition mob vote)

Mob vote

In the four annual Minecraft events MINECON Earth , MINECON Earth , MINECON Live and Minecraft Live , the public voted on a mob to be added to Minecraft. In the first vote, the winner was the phantom (then known as 'Mob B' or 'The Monster of the Night Skies'). In the second, the winner was the taiga biome which mainly added the Fox mob. In the third, the winner was the mountain biome which mainly added the Goat mob. In the fourth, the winner was the glow squid. Before the second vote, Minecraft China had a mob vote, the winner was the Panda.

Classification

Most of the mobs are divided into different types, such as the animals or the monsters, but some creatures are assigned to a more detailed group. There are a total of four mob classifications that have different effects than other mobs.

Weaknesses and immunities

Some mobs are weak or immune to certain kinds of damage. Sea creatures, such as turtles, take more damage from tridents that are enchanted with Impaling.&#;[Java Edition only]&#;[untilJE Combat Tests]Skeletons and their variants are immune to drowning. All undead mobs are healed by Potions of Harming, but take extra damage from weapons enchanted with Smite, along with taking damage from Potions of Healing. Many of these weaknesses and immunities are a result of what category (see below) of mobs that the mob falls into.

Undead mobs

Main article: Undead

This group of mobs includes drowned, husks, phantoms, skeletons, skeleton horses, strays, withers, wither skeletons, zoglins, zombies, zombie horses, zombie villagers, and zombified piglins. These mobs are damaged by potions of Healing, healed by potions of Harming, and are immune to drowning (except for husks and zombies, which turn into zombies and drowned if drowning, respectively) and poison damage. Zombies, zombie villagers, drowned, skeletons, strays, and phantoms burn when under direct sunlight, unless they are touching water or wearing a helmet. Under the fire resistance effect, undead mobs still catch fire in direct sunlight but do not get hurt by the fire. All undead mobs except for drowned, phantoms, and withers sink in water. All undead mobs take extra damage from weapons enchanted with Smite,&#;[Java Edition only] and are ignored by withers.

Most undead mobs have the ability to pick up items. Some can spawn wearing armor

For those who are looking for a more relaxed Minecraftexperience, you can disable monsters from spawning.

There are multiple ways you can set your server up to avoid monsters.

Disabling all monsters

Minecraft Bedrock Edition players can edit their world settings under “Game” and uncheck the box next to “Mob Spawning.”

Java Edition players can type “/gamerule doMobSpawning false” into the chat bar to disable mobs. You’ll need to be a server admin and have cheats enabled.

Keep in mind using this setting will also disable friendly spawns as well, like animals.

Disabling specific monsters

You can use Command Blocks to kill individual monsters as soon as they spawn, leaving behind any drops. You’ll need to do the following:

  1. Place a Command Block
  2. Set the block type to “repeat” or “current” depending on your version of Minecraft.
  3. Set the condition to “unconditional.”
  4. Set the Redstone settings to “always active.”
  5. Insert the command “/kill @e[type=MOB-NAME]” into the command input section.

Just replace “MOB-NAME” with the monsters respective namespaced ID. The IDs for monsters can be found on their Minecraft wiki page. For example, if you want to consistently kill all skeletons, you’ll have to use “/kill @e[type=skeleton]” to do that.

Doing this will instantly kill any mob that spawns in, leaving behind any potential drops. If you don’t want to see any drops left behind, you can use “/tp @e[type=MOB-NAME] ~ ~” instead, which will teleport the mob to a void to vanish.

Spawning refers to the creation and placement of players and mobs in the Minecraft world.

Player spawning[]

World spawn[]

See also: Multiplayer spawning details

New players initially spawn within a small area surrounding the world spawn point when the server is not in Adventure mode. This area is 21×21 blocks by default, but can be changed by the gamerule in both single and multiplayer. Upon death or return from the End dimension, the player respawns within this area unless the player's individual spawn point changed (by using a bed or respawn anchor, or the command).

When the player first loads into the world or respawns, the game searches within the world spawn area and tries to place the player on a random grass block. Upon spawning, the player is placed on the highest valid spawn point block of the X and Z spawn coordinates, even if this would set the player above the maximum build height. However, if there are no valid spawn points but a grass block that was determined to be an invalid spawn point due to being blocked by a block above it (though the grass block would decay soon after), the game checks the closest two free spaces from below and the player spawns there. If there are absolutely no grass blocks, the player spawns directly at the world spawn point, which can even result in players spawning above the Void if there are no blocks at that location.

The world spawn point also determines the center of the permanently loaded spawn chunks.

The world spawn point itself can be changed using the command.

Bedrock world spawn search[]

In Bedrock Edition, when a player creates a new world, the world spawn point is restricted to specific biomes. The algorithm starts searching from coordinate 0,0, continuing outward until an acceptable biome is found for the world spawn point. Using add-ons, a rare biome can be designated to cause the player to spawn at a distant location, but the game crashes if the biome does not exist or cannot generate.

The algorithm searches for these biomes:

The player spawns within a 5-block radius of the point selected in the chosen biome, sometimes resulting in the player spawning outside the intended spawn biome, ending up in a beach, river, or swamp biome. It is also possible (but rare) for a player to spawn initially underwater and start drowning.[1]

A search for a valid world spawn biome is not performed for Flat and Old world-types.

Adventure mode[]

When the server's settings specify the default game mode as Adventure (using the server.properties), then the normal spawning mechanic is ignored, and players are spawned directly on the world spawn point. This includes the X, Y, and Z coordinates, even if there is no block there, and even if there are blocks above it.

If the Y coordinate is not within a valid spawning area, then the server looks up until it finds one, up to a maximum of Y= If there is space to spawn, but it is in mid-air, the player spawns in mid-air, even falling into the Void if there is a hole.

Location[]

There are several ways to determine the world spawn point:

  • A compass (that hasn't been assigned to a lodestone) always points to the world spawn point.
  • Doing the commands then .
  • If commands are disabled, remove all the grass blocks in the 21×21 spawn area (or place a block above them to make them invalid), make sure the individual spawn point is disabled, and die.
  • Entities, other than players, falling into the exit portal in the End land exactly at the world spawn point. Items thrown in mark the spot in the Overworld. Players spawn like they normally do, allowing this action to be used to perform the above without dying, and thus can be performed in hardcore mode.
  • Mods or external programs, such as NBTExplorer or MCEdit, can also be used to find and set the world spawn point.

Individual spawn[]

The individual spawn point of the player can be changed by sleeping in a bed, using a respawn anchor, or using the or command. If the individual spawning area of the player is obstructed upon death, the player respawns at the world spawn.

Sleeping in a bed allows for leniency in obstruction, in that the player respawns on other blocks near the bed if the original point becomes blocked. The same is true for the respawn anchor. If the spawn point set via or becomes obstructed, the player is not given this leniency in respawning.

Natural generation[]

Animals[]

In Java Edition many animals generate upon initial chunk creation. These spawns occur only once per chunk. They are not affected by the command.

One in ten newly-generated chunks attempts to generate animal mobs, usually in packs of up to 4 of the same species. The spawn attempt always starts on top of the highest available block in a randomly chosen column within the chunk. The chosen position must not be a solid block for the animals to generate. Once the starting position is chosen for a chunk, a second position is chosen in a 9×9 block area around the starting position. Blocks toward the center of the 9x9 area are more likely to be chosen than blocks toward the edge. The block does not need to be a grass block nor does it need to be illuminated as it does with mob spawning. If an animal can spawn at the second position, it does so. The second position becomes the first position, and a new second position is chosen like before in a 9x9 area. This process can repeat until each chunk has attempted to spawn 1–4 mobs.

In Bedrock Edition animals do not spawn during chunk generation, but they continually attempt to spawn everywhere as part of the environmental spawning algorithm, according to their spawn weights, biome tags, and block requirements (see Bedrock Edition under Spawn Cycle, below).

There are 2 types of animals: common animals and biome-specific animals.

Common animals

Common animal mobs do not spawn in desert, badlands, beach, snowy tundra, river, ocean, or mushroom fieldsbiomes.

Biome-specific animals

Some animal mobs spawn only in specific biomes.[more information needed]


Randomness for animal spawning is derived from the world seed, which means that worlds with the same seed always generate chunks with the same animals in the same places.

Monsters[]

Monsters cannot spawn when the difficulty is set to Peaceful (except piglin&#;[BE only] and hoglin). At any higher setting they spawn at light level 7 or less. The player cannot sleep when a monster (other than hoglin; and in Java Edition, also include slime, magma cube and non-hostile zombified piglin) is nearby, even if the monster has no path to the player.

Common monsters

Common monster mobs can spawn in almost any biome in the Overworld (except for mushroom fields). They can spawn on the surface and underground. The weight determines the spawn rate in the Bedrock Codebase.

Biome-specific monsters

Some monsters spawn only in specific biomes.

Other mobs[]

In Java Edition these mobs still spawn if the command is set to , because they spawn as part of structure generation. In Bedrock Edition nothing spawns if the command is set to

  • Villagers, iron golems, stray cats, pigs, cows, sheep, and horses generate as part of the village generation.
    • Specific animals spawn as part of specific village structures: Animal pens (cow, sheep, pig, or horse), stables (horse, cow, or pig), butcher's houses (pig, cow, or sheep), and shepherd's houses (sheep).
    • Each villager spawns in a house with a bed, and an iron golem spawns as part of meeting points.
    • Zombie villagers can spawn as part of zombie village generation, where they never despawn naturally.
    • Cats also spawn upon generation in abandoned villages.
  • A single witch and black cat spawn within a swamp hut upon generation.
  • Three elder guardians generate as part of a single ocean monument.
  • A single ender dragon is created in the End when the dimension is created. The ender dragon can also be respawned by placing end crystals on the exit portal.
  • Shulkers generate as part of end cities.
  • Vindicators and evokers generate as part of woodland mansions.
  • A villager and a zombie villager generate as a part of an igloo if it generates with a basement.
  • Drowned generate as part of some underwater ruins.&#;[JE only]
  • Illagers spawn from pillager outposts, raids, and patrols.
  • Phantoms spawn whenever a player hasn't slept for 3 or more days.

Spawn cycle[]

Java Edition[]

Mobs are broadly divided into six categories: hostile, friendly, water creature (squids and dolphins), underground water creature (axolotls and glow squids), water ambient (all 4 types of fish), and ambient (bat). Hostile and water mobs have a spawning cycle once every game tick (1&#;20 of a second). Friendly mobs have only one spawning cycle every game ticks (20 seconds). Because of this, where conditions permit, hostile mobs spawn frequently, but passive mobs (animals) spawn rarely. Most animals spawn within chunks when they are generated.

Mobs spawn naturally within a square group of chunks centered on the player, 15×15 chunks (× blocks). When there are multiple players, mobs can spawn within the given distance of any of them. However, hostile mobs (and some others) that move farther than blocks from the nearest player despawn instantly, so the mob spawning area is more-or-less limited to spheres with a radius of blocks, centered at each player. In multiplayer, mob caps are shared by all players, no matter where they are.

Every game ticks (20 minutes) the game attempts to spawn a single wandering trader with two leashed llamas within 48 blocks of a player or at a village meeting place, if no wandering trader exists in all loaded chunks. The trader does not spawn when the player is underground.‌&#;[Java Edition only]

Java Edition mob cap[]

Jigsaw Block (top texture) JE2 BE2.png
This section needs expansion.&#;

You can help by expanding it.
Instructions: The new charge/cost/energy system used for Soul Sand Valleys and Warped Forests. Each mob has a cost for spawning and deducts it from the biome's total energy. Is it reduced per entity spawn or per pack spawn? How does energy recharge? Etc. See Biome.java, NaturalSpawner.java, and PotentialCalculator.java.

Mob caps are directly proportional to the total number of chunks eligible for spawning. To calculate the cap, the spawning area is expanded by one chunk in every direction (so the default gives 17×17 chunks), then the total number of chunks is plugged into the following formula:

mobCap = constant &#; chunks ÷

The constants for each group are as follows:

  • Monster = 70
  • Creature = 10
  • Ambient (bats) = 15
  • Underground water creature (axolotls, glow squids) = 5
  • Water creature (squids, dolphins) = 5
  • Water ambient (fish) = 20
  • Misc = -1

The "misc" category is used only by entities that are not mobs, do not spawn naturally, and/or following different spawning rules than other mobs. As such the mob cap has no bearing on mobs of this category.

In singleplayer, there are always chunks in range, so the constant is always used as the global mobcap.

In multiplayer, the global mobcap grows as more chunks are loaded. As chunks that are in the range of multiple players are counted only once, more chunks and higher mob caps result from the players spreading out more.

The number of mobs is checked once per each chunk against the cap. If the number of mobs (dead or alive) in a category is at its cap, the entire spawning cycle for that category is skipped. The area checked for mobs is the same as the area used for calculating the mobcap, which is the spawning area expanded by one chunk in every direction. The mobcap count is separate for each dimension.

Every chunk, the game checks the mobcap. As such, you can reach mobcap+pack size from natural spawns.

When is set to , spectators do not raise mobcap.

Pack spawning[]

For each spawning cycle, attempts are made to spawn packs of mobs per each eligible chunk. An eligible chunk is determined by the same check for which chunks are random ticked. A random location in the chunk is chosen to be the center point of the pack. If the block in which a pack spawn occurs is an opaque full cube, further pack spawn attempts are canceled. There are a maximum of 3 pack spawn attempts per mob category.

The pack is spawned within a 41×1×41 (that's a 41×41 square that is one block high) area centered at the initial block. Mobs spawn with the lowest part of their body inside this area. For each spawn attempt, from the location of the previous attempt, a location up to 4 blocks away from the previous attempt is chosen at random. Thus, the spawns are heavily skewed toward the center of the pack. Approximately 85% of spawns are within 5 blocks of the pack center, and 99% within 10 blocks of the center. If the pack spawn enters a biome different from the starting biome, the rest of the pack and that spawn are canceled.

All mobs within a pack are the same species. The species for the entire pack is chosen randomly, but based on a weight system from those eligible to spawn at the location of the first spawn attempt in the pack.

The game checks on each spawn if the number of mobs that have been spawned for the pack is equal to the max spawn attempts, as well as the location's spawn potential.

Pack spawn size

Pack spawn attempts max out at:

  • 8 Wolves, cod, and tropical fish
  • 6 Horses and Donkeys
  • 1 Ghast
  • 4 for any other mob

When the max pack size is less than the number of possible spawn attempts, some spawns attempts fail, but are seen more commonly in practice. Based on the number of mobs that have been successfully spawned. If the max pack size is greater than the number of spawn attempts, one gets only the number of spawns from the spawn attempts. Some mobs have a minimum and max pack size, meaning there is an even chance for any number of spawn attempts between them occurring.

  • For zombie villagers, drowned, pillagers, donkeys in savanna biomes, parrots in jungles excluding bamboo jungle and jungle, cats in swamp huts and witches, it is 1.
  • For parrots in bamboo jungles and Jungle, polar bears, squids in lukewarm oceans, pandas and dolphins, it is
  • For donkeys in plains biomes, ocelots and pufferfish, it is
  • For endermen except in the End and in nether wastes, and squids except in lukewarm oceans, it is
  • For rabbits and blazes, it is
  • For guardians, foxes, zombified piglins in crimson forests and striders, it is
  • For turtles, it is
  • For horses, it is
  • For piglins and hoglins in crimson forests, it is
  • For Cod it is
  • For llamas, it is
  • For mooshrooms, it is
  • For wither skeletons and skeletons, in nether fortresses, it is 5.
  • For bats and tropical fish, it is 8.
  • For every other mob, it is 4.
Pack spawn location

For all dimensions, structure-based spawns take priority over biome for hostile spawns. This means that in a swamp hut, pillager outpost, nether fortress (outer bounding box only when there is nether bricks below it&#;[JE only]), and ocean monument, one sees only the corresponding hostile mobs for that structure within that structure.

In the Overworld, this depends on the location:

  • Jungle biomes have a higher chance to spawn chickens.&#;[Java Edition only]
  • Badlands biomes spawn only hostile mobs and bats.
  • River and frozen river can spawn only drowned, squid, and salmon underwater.
  • Ocean biomes do not spawn passive mobs. They spawn drowned, and the other hostile mobs. Frozen oceans do not spawn dolphins, but do spawn polar bears.
  • Snowy Tundra biomes do not spawn animals other than polar bears and rabbits.
  • Swamp huts spawn only witches, cats, and bats.
  • Ocean monuments spawn guardians, other water mobs and bats.
  • Pillager outposts spawn pillagers, other passive mobs and bats.
  • All other overworld biomes spawns common animals and common monsters, as well as slimes, dependent on spawn conditions.

In the Nether:

Spawn conditions[]

Whether a spawn condition fails differs from the above determination if the game tries to spawn them in that biome. For example, dolphins can have pack spawns that occur inside of frozen ocean and deep frozen ocean biomes, but no other biomes. These rules apply to variants of the same mob, such as baby zombies and spider jockeys.

Each individual spawn attempt succeeds only if all of the following conditions are met:

  • There must be no players or the world spawn point within a 24 radius block distance (spherical) of the spawning block
  • The number of loaded mobs of that type must be less than the mob cap for that type. (I.e. the corresponding mobcap must not be full)
  • The mob's collision box upon spawning must not collide with another collision box. A mob cannot spawn inside of anything that would collide with it upon spawning.
  • The mob's collision box must not intersect with a solid block.
  • For all mob types excluding passives and fish, spawns fail unless within a radius block sphere around the player. For fish, spawns fail unless within a 64 block radius of the player. [2]
  • is
  • For non-aquatic mobs, the spawning block and the block above that cannot be rails, powered rails, detector rails, activator rails, redstone components, wither roses (except for wither skeletons) or sweet berry bushes (except for foxes).
Hostile mobs
  • The difficulty must not be Peaceful, excluding piglins and hoglins
  • This also affects ocelots[3]
  • For all hostiles other than guardians, drowned, and phantoms:
    • the block directly below it must have a solid, opaque, top surface (this includes upside down slabs, upside down stairs, and others) or be soul sand or a slime block.
    • the block directly below it must not be bedrock, barrier, or‌ any type of trapdoor‌ or glass.
    • The mob's collision box must not collide with any liquid.
    • The block above the spawning block must be transparent
  • For slimes from swamp biomes, creepers, skeletons, wither skeletons, witches, zombie villagers, husks, strays, drowned and spiders:
    • The light level divided by 8 is the chance of a spawn failing; thus mobs spawn at light level 7 and below.
    • Spawns with sky access in overworld have an additional 50% failure rate
    • If it is a slime from a swamp biome, then
      • the spawning block must be in a swamp biome
      • the spawning block be on level 51 through 69 inclusive
      • chance of failure based on the phase of the moon
      • with a 50% chance of failure.
    • If it is a husk or stray, then
      • The location of the spawn must have sky access (i.e. have a skylight level of 15).
    • If it is a skeleton in a Nether fortress, then
    • The light checks in the general hostile mob check don't apply to:
      • Slimes from slime chunks (see the slime page for details), which spawn when:
        • the spawning block is below level
        • with a 90% chance of failure.
      • If it is a Ghast, then
        • With a 95% chance of spawn failure.
      • If it is a Magma cube, then
        • the block below must not be a nether wart block.
      • If it is a hoglin, then
        • the block below must not be a nether wart block.
      • If it is a blaze, then
        • the light level must be 11 or darker.

Top 5 ways to prevent mobs from spawning in Minecraft

Most living creatures in Minecraft can spawn in specific conditions without the player doing anything.

Some mobs, like zombies and skeletons can spawn in multiple ways, like through spawners and automatically in places where the light levels are less than 7.

Mobs spawning may or may not be beneficial for the player, depending on where it spawns.

Players often try to stop mobs from spawning above their mob farms as this will reduce its numbers inside the farm and lower its efficiency.

Ways of preventing mobs from spawning in Minecraft

5) Using light blocks

Minecraft is full of scary hostile mobs that spawn during the nighttime when the light levels fall under 7. To prevent this, players can use blocks that emit light, such as torches and glowstone, in areas where they want to prevent these mobs from spawning.

Torches are one of the easiest light-emitting items to craft as they only require sticks and coal. Players can create torches by placing a stick with a coal on top of it in the crafting grid. Putting down torches on a spawner can prevent mobs from spawning as well.

4) Break spawners

Spawners are rare blocks that look like a cage and have miniature mobs inside of them. Players can identify which mob can spawn from a spawner by inspecting the small mob spinning inside the block.

If the player does not plan on creating a mob farm from these spawners, they can break them to prevent further mobs.

3) Fluids

Apart from underwater mobs, creatures in Minecraft cannot spawn on any watery substance. Placing water or lava is a very cheap method for players looking to stop mobs from gathering at the same place.

2) Half blocks

Slabs can be crafted from normal blocks (Image via Minecraft)

Mobs in the game do not spawn on blocks such as slabs that are half the height of a regular block. By using this game mechanic, players can put down these items to make sure mobs can not spawn in unwanted areas.

1) Transparent blocks
