In Control!Server-admin rules — block, modify, or trigger events on mob spawn / damage / loot

Version: 10.2.6 · MC 1.21.1 · NeoForge 21.1.228 · Java 21

About

Admin tool. JSON rule files in config/incontrol/ let you customise mob spawning at fine grain. Block creepers from forest biomes, double zombie spawn rate at night, prevent endermen from teleporting in caves, force gold drops on rare mobs. Used by the ATM10 pack devs to balance encounter density. Players don't interact with it; admins tune it server-side.

Things to do

(admin) Edit spawn.json + summon.json to tune mob density
(admin) Set per-dimension or per-biome spawn caps

Getting started

Server config at config/incontrol/. /incontrol reload applies changes without restart.
