by matthew_mgp

Slime Detector is a Forge utility for 1.20.1 that helps players find slime chunks with a single craftable item.

ForgeClient and serverMIT License1.20.1

What it does

Holding the Slime Detector item tells the player at once whether the chunk they are standing in is a slime chunk, so slime farms can be placed without guesswork. The item is a plain, vanilla-friendly addition with no custom screens or menus, and the only new recipe is the item itself, crafted from common materials. Players who want a quick way to find a spot for bounce mobs can use it instead of checking coordinates by hand. The mod runs on Forge for 1.20.1 and is published under the MIT License. It is not open source. Client and server both need the mod installed.

Key features

  1. Instant chunk check

    The detector reports immediately whether the player is standing in a slime chunk.

  2. Single craftable item

    The whole addition is one item, crafted with ordinary materials, and nothing else is added to the game.

  3. Minimal interface

    No complex UI or menus are introduced, so the item stays out of the way of other mechanics.
