MobTweaks – Wiki (English)

Listed as "Mob Controller" on Modrinth β€” same mod, different display name there because "MobTweaks" was already taken.

This page walks through day-to-day usage of MobTweaks, plus the full command and ability reference. For a quick feature overview see the README β€” this page goes into more depth.

Contents

Getting started

  1. Run /mobtweaks open (OP4 by default) to launch the GUI editor.
  2. Pick a mob from the filterable list on the left.
  3. Toggle its abilities (checkboxes), configure loot overrides, and set spawn restrictions (dimension/biome/light level) β€” every change autosaves instantly.

All commands

Base command /mobtweaks, alias /mt. The GUI editor covers everything a command can do and is the recommended way to configure things; commands share the exact same validation logic for scripting/console use.

Command Description
/mobtweaks open Opens the GUI editor.
/mobtweaks ability list [entityType] Lists ability states for one mob type, or all configured overrides.
/mobtweaks ability set <entityType> <ability> <true|false> Sets a single ability toggle for a mob type.

Abilities in detail

Vanilla-special mobs

These mobs get specific, named abilities in addition to the generic ones below:

Mob Ability
Creeper, Ghast, Wither, Ravager, Silverfish Explosion/griefing (block destruction)
Any explosion source, including TNT Explosion block damage (covered separately from the mob-griefing event, since vanilla TNT never fires it)
Zombie Door-breaking
Zombie Villager infection
Enderman Block pickup/placement

Every other registered mob (vanilla or modded)

Any mob type not listed above β€” including every modded mob β€” automatically gets two generic toggles that work without any per-mod setup:

  • Griefing allowed β€” hooks the same generic griefing event vanilla-special mobs use.
  • Can spawn β€” cancels natural spawning for that mob type entirely.

Loot table overrides and dimension/biome/light-level spawn restrictions apply to every mob type equally, vanilla-special or not.

Known limitation

Non-mob entity types (e.g. item frames, boats) also appear in the mob list since there's no reliable way to filter "is this actually a mob" from registry metadata alone β€” their toggles are simply inert since the underlying events never fire for them. Not a bug, just how the registry scan works.
