In Control Mod Wiki

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.

All configuration files are located in the config/incontrol/ directory. These files use JSON syntax and are evaluated by the mod to apply rules.

Conditions are tests that must be true for a rule to execute. Most conditions can be used across all JSON files.

Common Conditions

Actions define what happens when all conditions in a rule are met.

Spawn Actions (spawn.json)

The spawn.json file is used to restrict or modify mobs that are already attempting to spawn. Rules are evaluated from top to bottom, and the first matching rule is applied.

Note: spawn.json cannot add new spawns; it can only filter or modify existing ones.

Example: Blocking Creepers in the Overworld

[
 {
 "dimension": "minecraft:overworld",
 "mob": "minecraft:creeper",
 "result": "deny"
 }
]

Example: Buffing Zombies at Night

[
 {
 "mob": "minecraft:zombie",
 "time": "13000-24000",
 "healthmultiply": 2.0,
 "damagemultiply": 1.5,
 "result": "default"
 }
]

Introduced in 1.16+, spawner.json allows you to add entirely new spawn rules to the world. Unlike spawn.json, all matching rules in this file are executed.

Spawner Keywords

• mobs: A list of mob objects to spawn.
• persecond: How often the spawner attempts to run (e.g., 0.5 means every 2 seconds).
• attempts: Number of attempts per cycle.
• amount: Number of mobs to spawn per successful attempt.
• conditions: The conditions required for this spawner to run.

Example: Spawning Blazes in Deserts

[
 {
 "mobs": [
 {
 "mob": "minecraft:blaze",
 "weight": 10,
 "groupcountmin": 1,
 "groupcountmax": 2
 }
 ],
 "persecond": 0.1,
 "attempts": 20,
 "amount": {
 "minimum": 1,
 "maximum": 3
 },
 "conditions": {
 "dimension": "minecraft:overworld",
 "biome": "minecraft:desert"
 }
 }
]

Loot Control (loot.json)

This file allows you to add or remove items from a mob's drop table. You can use conditions like playerhelditem to make specific items drop only when killed with a certain tool.

Experience Control (experience.json)

Controls the amount of XP dropped by a mob.

In Control! provides several commands for debugging and management. All commands start with /incontrol.
