Zombie Awareness

When a player is hurt, blood is left on the ground, and at low health the player bleeds out now and then. Nearby monsters sense that scent and follow it to the player. Several other actions also draw attention: mining or placing blocks, explosions, shooting bows and crossbows, eating, opening doors, gates, chests, barrels and pistons, and using levers, buttons, pressure plates, tripwires, note blocks and records. Zombies calling to one another can alert the rest of the group too. The louder a sound is, the farther away it can be heard.

Monsters can spot exposed light sources from a long distance and will come to investigate when they have line of sight to one. Pistons or TNT can lure zombies toward a chosen area, which helps a player escape, since monsters always head for the loudest noise. Which monsters receive these behaviors is configurable. Zombie, husk, creeper, skeleton, stray, witch and zombie villager are enabled by default. An optional setting lets mobs gather into large groups and wander the surface, and it is off by default.

The mod requires CoroUtil. It runs on Fabric, Forge and NeoForge with the 1.21.0-1.13.2 files, and game versions 1.12.1 – 1.21.1 are listed across seven release versions. Both the server and every player need it. The code is not open source and is covered by All rights reserved, though the source code and issue tracker are public.
