by T0mt4ru

Tom's Mob Stopper blocks chosen mobs from spawning, using a plain text file that lists which mobs to stop.

NeoForgeServer-side onlyMozilla Public License 2.01.21.1 – 1.21.4

What it does

On first load the mod generates a file named tomsmonstopper.txt in the config folder. Each mob to stop goes on its own line in the form modID:mob name, without quotation marks, so a server owner can keep sheep out of a world by adding one entry. Server-side only, so only the server needs the mod, and players join without installing anything. Published for NeoForge on 1.21.1 – 1.21.4 under the Mozilla Public License 2.0, and the mod is not open source.

Key features

  1. Spawn blocklist

    Mobs named in the list no longer spawn in the world, while everything else spawns as usual.

  2. Plain text config

    The blocklist is a text file in the config folder, so entries can be added or removed without editing code.

  3. Namespaced mob IDs

    Each entry uses the modID:mob name format, which lets a server stop mobs from any installed mod.
