This is a simple mod that gives you full control on where mobs are allowed to spawn. It is based on a rule system. The rule files are located in config/incontrol.

Introduction

There are currently five rule files (as of 3.5.1):

spawn.json: with this file you can block spawning of certain creatures under certain conditions. In addition, when a spawn is allowed you can also alter some of the properties of the mob like maximum health and others
summonaid.json: this is a file that is structured the same as spawn.json but is only used when zombies are summoned for aid
potentialspawn.json: with this file you can remove and add spawn rules under certain conditions. The rules in this file are used before the rules in spawn.json are fired so make sure that when you add a rule for new mobs here, the new mobs are allowed in spawn.json
loot.json: with this file you can control the loot that mobs drop when they are killed based on various criteria
experience.json: with this file you can control how much experience you get from killing mobs based on various criteria
