Mob Limiter

Mob Limiter

Caps how many mobs can exist in a single chunk, preventing runaway spawning (farms, spawners, or natural spawning in unloaded-then-reloaded areas) from tanking performance. Enabled by default. Config file: module/mob-limiter/config.yml.

yaml 
max-mobs-per-chunk: 50

# If set to true, mobs spawned from spawners will not be counted towards the chunk limit.
ignore-spawners: false

    ZOMBIE: 10
    SKELETON: 10
    CREEPER: 8
    SPIDER: 8
    ENDERMAN: 5

    IRON_GOLEM: 3
  • max-mobs-per-chunk — global cap on living entities per chunk, checked before any spawn is allowed to complete.
  • ignore-spawners — when true, mobs that spawn from a mob spawner block don't count toward the chunk's limit (useful if you want farms to keep working while still capping natural spawns).
  • per-type-limits — an additional, tighter cap for specific entity types, checked independently of the global limit. Any EntityType name not listed here isn't individually capped (only the global max-mobs-per-chunk applies to it).

Configurable in-game via the Mob Limiter panel in the Admin GUI.
