Why a mob spawns (EntitySpawnReason).

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Natural

NATURAL: the level’s own spawning each tick.

ChunkGeneration

CHUNK_GENERATION: a new chunk’s creature packs.

Spawner

SPAWNER: a mob spawner block.

TrialSpawner

TRIAL_SPAWNER: a trial spawner.

Reinforcement

REINFORCEMENT: a zombie calling for help.

Patrol

PATROL: a pillager patrol.

Structure

STRUCTURE: a structure’s own mobs.

Event

EVENT: a world event, such as a village siege.

Command

COMMAND: /summon.

SpawnItemUse

SPAWN_ITEM_USE: a spawn egg.

MobSummoned

MOB_SUMMONED: a mob that summons another (an evoker’s vexes).

Conversion

CONVERSION: a mob that became another.

Breeding

BREEDING: a baby.

Triggered

TRIGGERED: a block or item set it off (a sculk shrieker’s warden).

Jockey

JOCKEY: a rider spawned on a mount.

Dispenser

DISPENSER: a dispenser fired a spawn egg.

Bucket

BUCKET: a bucketed mob released.

Load

LOAD: loaded from saved data.

DimensionTravel

DIMENSION_TRAVEL: a mob that crossed a portal.
