Apathy
by quat
Apathy controls whether mobs attack players, through a JSON rule system that sets aggression by world difficulty, mob type tags and other conditions.
What it does
Apathy can turn off mob aggression entirely, or limit it to the cases a rule set defines. Rules can depend on the current world difficulty, on mob type tags, and on the other conditions the rule format supports, so a server can build exactly the scenario it wants. Rules can also integrate with vanilla scoreboard objectives, advancements, locations and biomes.
The mod can disable entities attacking players, make the Ender Dragon and Wither fights less aggressive, and let players opt in or opt out of player-versus-environment scenarios by adding them to player sets. It is a port and rewrite of the earlier Apathetic Mobs mod, and the author describes it as considerably more configurable.
Apathy runs on the server alone, so players join without installing anything. It is published for Fabric, Forge, NeoForge and Quilt across 11 release versions, 1.16.5 – 1.21.1. The mod is open source under the GNU Lesser General Public License v3.0 only. Berk Origins requires it.
