Overview

In Control! is a comprehensive tool designed to manage every aspect of mob behavior and presence in a Minecraft world. Unlike mods that simply add content, In Control! acts as a logic layer, allowing you to define exactly when, where, and how mobs appear. It supports complex conditions such as biomes, dimensions, time of day, player distance, and even custom game stages.

Key Features

  • Spawn Restriction: Block specific mobs from spawning in certain biomes or dimensions.
  • Spawn Addition: Add mobs to dimensions where they don't naturally occur (e.g., Blazes in the Overworld).
  • Attribute Modification: Change a mob's health, speed, damage, and equipment upon spawning.
  • Loot & XP Control: Customize what items mobs drop and how much experience they grant.
  • Event-Based Spawning: Trigger mob spawns based on player actions like breaking blocks or killing other mobs.
  • Area Management: Define specific safe zones or high-danger areas using the new Area system.

Frequently asked questions

How do I get started with In Control?
Create or edit the JSON rule files in the mod's config folder, then reload them in-game with the reload command. Each rule defines a set of conditions and the spawn behavior to apply when those conditions match.
What's the difference between spawn rules and spawn filters?
Spawn rules decide whether a mob is allowed to spawn at all under given conditions, while filters narrow down which mobs, biomes, dimensions, or blocks a rule applies to. You typically combine both: a filter selects the mobs, and the rule sets the outcome.
Do I need to restart the game after editing rules?
No, you can reload the rule files with the mod's reload command while the game is running. A full restart is only needed if you changed something outside the rule files themselves.
Why aren't my In Control rules doing anything?
The most common causes are a JSON syntax error, a rule that never matches its conditions, or another mod overriding spawns after In Control runs. Check the log for parse errors and use the debug output to see which rules are being evaluated.
