Mobs only spawn at night, and “despawn” at day.
\nYou also get a few seconds of darkness at when night starts and a few seconds of night vision when daytime starts, so you can keep track of the time even while caving without a clock.<\/p>\n
It will only despawn entities that:
\n– Are in the nocturnalmobs:hostiles tag
\n– Are in the overworld
\n– Do not have the {PersistenceRequired:1b} nbt (this includes mobs with nametags and those that have picked up items)
\n– Are not mounting an entity (careful with chicken jokeys!)<\/p>\n
By default, the mobs in the nocturnalmobs:hostiles tag are:
\n– zombies
\n– zombie villagers
\n– husks
\n– drowneds
\n– skeletons
\n– strays
\n– spiders
\n– cave spiders
\n– creepers
\n– endermans
\n– phantoms
\n– slimes
\n– witches
\nother mobs must be added via datapacks<\/p>\n
You may disable the darkness and night vision by executing these commands:
\n– \/function nocturnalmobs:config\/disable_night_alert
\n– \/function nocturnalmobs:config\/disable_day_alert<\/p>\n
and re-enable them using:
\n– \/function nocturnalmobs:config\/enable_night_alert
\n– \/function nocturnalmobs:config\/enable_day_alert<\/p>\n","protected":false},"excerpt":{"rendered":"
