Nov 2, 2024 · Example of a mob pack spawning. The mob spawning area is shaded blue. The yellow figures represent the actual positions that mobs could spawn in after checking the environment. Note that the mobs can spawn inside torch and ladder blocks. But they can't spawn on top of glass because it is not opaque. The red cube is the center of the pack.
May 21, 2015 · Yellow crosses mean that mobs can spawn in night, red crosses that they can spawn even in a day. If the block is not capable of spawning a mob, there will be no cross (no matter if there is a lot of light or block type blocks the spawning) - this can help you to actually SEE this whole thing in practical manner.
Plus as far as I can tell, there are no other blocks within 20 blocks (if it's horizontal, and not vertical) of the roof that the game can check, to cause the mobs to spawn on string. Also, does string even prevent mobs from spawning. tl;dr: Do mobs spawn on string, how does the spawning mechanic work, and how can I prevent them from spawning
Mobs spawn naturally within a 15x15 chunk (240x240 block) area around the player. When there are multiple players, mobs can spawn within this distance of any of them. However, mobs that move farther than 128 blocks from any player will immediately despawn, so the mob spawning area is effectively limited to spheres with a radius of 128 blocks, centered at each player.

World spawn
New players initially spawn within a small area surrounding the world spawn point when the server is not in Adventure mode. 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 /spawnpointcommand). This area is 21×21 blocks by default in Java Edition or 5×5 in Bedrock Edition, but can be changed by the spawnRadiusgamerule in both single and multiplayer. When set to 0, the...
Individual spawn
The individual spawn point of the player can be changed by sleeping in a bed, using a respawn anchor, or using the /setworldspawn or /spawnpointcommand. 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 /setworldspawn...
Animals
In Java Edition many animals generate upon initial chunk creation. These spawns occur only once per chunk. They are not affected by the /gamerule doMobSpawningcommand. 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 pos...
Monsters
Monsters cannot spawn when the difficulty is set to Peaceful (except piglin[BE only] and hoglin). At any higher setting they spawn when block light level is 0. 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 or deep dark). They ca...
Other mobs
In Java Edition these mobs still spawn if the /gamerule doMobSpawning command is set to false, because they spawn as part of structure generation. In Bedrock Edition nothing spawns if the /gamerule doMobSpawning command is set to false. Animal mobs Monster mobs Other mobs
Java Edition
Mobs are broadly divided into seven categories: hostile, passive, water creature (squids and dolphins), underground water creature (glow squids), axolotls, water ambient (all 4 types of fish), and ambient (bat). Most mobs have a spawning cycle once every game tick (1⁄20 of a second), but passive mobs have only one spawning cycle every 400 game ticks (20 seconds). Because of this, where conditions permit, hostile mobs spawn frequently, but passive mobs (animals) spawn rarely. Most animals spaw...
Bedrock Edition
Environmental spawning in Bedrock Edition shares broad similarities to natural spawning in Java Edition: mobs spawn in a radius around the player subject to block conditions, lighting conditions, biome conditions, naturally generated structure conditions, and caps. Many mobs spawn in groups (called "packs" in Java and "herds" in Bedrock). One notable difference from Java Editionis that most animals can spawn at light level 7 or higher rather than 9 or higher. There are two types of environmen...
General
1. In Creative or via a dispenser, the player can use spawn eggs to spawn most mobs. When mobs are spawned this way, all normal spawning requirements, such as light level and block type, are ignored (though monsters other than vindicators[BE only], evokers[BE only], shulkers, and ender dragon still cannot be spawned in peaceful). 2. Any entity can be spawned using the /summoncommand.
Java Edition
All monster, ambient, and aquatic mobs excluding shulkers, withers, elder guardians and ender dragons despawn unless they have been marked persistent. Other mobs that are not monster, ambient, or aquatic that do despawn include ocelots, stray cats, and wandering traders. 1. A mob that has had no player within 32 blocks of it for more than 30 seconds, or 10 seconds if in low light levels, has a 1⁄800 chance of despawning on each game tick (1⁄20 of a second), which is a 2.47% chance per second....
Bedrock Edition
In Bedrock Edition, like Java, despawning occurs based on distance and chance. 1. On simulation distances 6 and higher, almost all environmentally spawned mobs immediately despawn when they are either (1) in a chunk at the edge of the simulation distance (technically, a chunk not fully surrounded by 8 chunks that were simulated on the last game tick), or (2) more than 128 blocks from the nearest player. 2. On simulation distance 4, mobs immediately despawn when they are more than 44 blocks fr...

For example, phantoms can spawn in the sky above you and other mobs can spawn directly below you while you're flying, standing on a high platform, or above a cave. Mobs can only spawn in chunks that are being ticked. There is a 11⁄2000 chance of the mob spawning algorithm attempting to run per chunk, per tick. Source
