Package net.minecraft.world.spawner

Interface Spawner

All Known Implementing Classes:
CatSpawner, PatrolSpawner, PhantomSpawner, WanderingTraderManager, ZombieSiegeManager
public interface Spawner
Spawns entities in a world.

A spawner is typically used to spawn entities within a special context, such as cats in a village or wandering traders. This is different from

the mob spawner logic
which is used for the spawner block, or the structure spawn conditions (such as guardians) which is defined in ChunkGenerator.getEntitySpawnList(net.minecraft.registry.entry.RegistryEntry<net.minecraft.world.biome.Biome>, net.minecraft.world.gen.StructureAccessor, net.minecraft.entity.SpawnGroup, net.minecraft.util.math.BlockPos). However, cats in swamp huts are spawned in both CatSpawner and the normal structure spawning.
