Spawn cycle

Bedrock Edition

Natural spawning in Bedrock Edition shares only a few similarities to natural spawning in Java Edition. In Bedrock Edition, there are two main types of natural spawns: pack spawns and structure mob spawns. Structure mob spawns are mobs spawned as part of a structure, such as nether fortresses, witch huts, etc. Pack spawns account for all other types of natural spawns, including mobs that spawn individually (i.e. not in a pack of 2 or more). Both types of natural spawns follow the same rules for spawn conditions and the mob cap.
