Nocturnal Mobs

Mobs only spawn at night, and "despawn" at day. You 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.

It will only despawn entities that: - Are in the nocturnalmobs:hostiles tag - Are in the overworld - Do not have the {PersistenceRequired:1b} nbt (this includes mobs with nametags and those that have picked up items) - Are not mounting an entity (careful with chicken jokeys!)

By default, the mobs in the nocturnalmobs:hostiles tag are: - zombies - zombie villagers - husks - drowneds - skeletons - strays - spiders - cave spiders - creepers - endermans - phantoms - slimes - witches other mobs must be added via datapacks

You may disable the darkness and night vision by executing these commands: - /function nocturnalmobs:config/disable_night_alert - /function nocturnalmobs:config/disable_day_alert

and re-enable them using: - /function nocturnalmobs:config/enable_night_alert - /function nocturnalmobs:config/enable_day_alert
