Mobs Reducer [Achievement Friendly]

Does the constant horde of hostile mobs make exploring caves or building at night a stressful chore? If so, you'll love this addon!

This addon significantly reduces the spawn rate of hostile mobs by giving them a chance to be instantly removed when they spawn. By default, Monster and Raid mobs have a 50% chance to despawn, effectively cutting their numbers in half. This means you can explore and build with far fewer interruptions from dangerous creatures.

You can fine-tune every aspect of the experience. Use the in-game commands to set reduction chances from 0% to 100%, add custom mobs to categories like Animal or Creature, or blacklist specific mobs you never want to be affected. It's a perfect balance for players who want a more peaceful world without completely turning off the game's difficulty.

✨ Key Features

Slash Commands (/mobreducer:help, /mobreducer:config, etc.) that work without enabling cheats

Fully customizable reduction chances from 0% to 100%

Five distinct mob categories: Monster, Raid, Animal, Creature, and Blacklist, each toggleable independently

Multi-list protection ensures a mob can only belong to one category at a time

Blacklist system to exclude specific mobs (slimes, magma cubes, and ALL bosses are excluded by default)

Custom lists allowing any mob ID to be added to the Animal or Creature categories

Multilanguage interface supporting English, Spanish, Portuguese, French, and Italian with per-player language persistence

⚙️ How It Works?

When a mob spawns, the addon checks its category (Monster, Raid, Animal, or Creature). If the mob qualifies and is not on the blacklist, it has a configured chance to be instantly despawned and removed from the world. This check happens every 20 ticks.

Blacklist Priority:

• The blacklist has MAXIMUM PRIORITY. Any mob on the blacklist will NEVER be reduced.
• Default blacklist includes slimes, magma cubes, slime variants from several addons, and ALL bosses (Wither, Ender Dragon, Warden, and many addon bosses).

Customization & Extra Features:

• Custom Animal/Creature Lists: Add any mob ID from other addons to be treated as an Animal or Creature.
