Welcome to the No Slime Superflat Wiki

Welcome to the official documentation of No Slime Superflat, a lightweight Minecraft mod designed to prevent slimes from spawning in Superflat worlds. This wiki contains all the information you need about the mod, including installation guides, technical documentation, and porting instructions for developers.


About the Mod

No Slime Superflat is a simple yet effective solution for players who want to enjoy Superflat worlds without the annoyance of slime spawns. Unlike other mods with similar functionality, this project focuses on minimalism: no configuration files, no commands, and no complex setup. Just install it and it works.

The mod was created as an alternative to existing solutions, prioritizing simplicity and compatibility with the latest Minecraft versions through the Fabric mod loader.


Main Features

  • Zero Configuration: No config files to edit or commands to learn
  • Automatic Detection: Automatically identifies Superflat worlds
  • Performance Optimized: Minimal overhead, only active when slimes attempt to spawn
  • Spawner Compatible: Does not affect slimes generated from mob spawners
  • Lightweight: Minimal code footprint with only two Java classes

How It Works

The mod uses Fabric's event system to intercept entity loading events. When a slime attempts to spawn, the mod performs the following checks:

  1. Verifies if the entity is a Slime
  2. Ensures the check runs only on the server side
  3. Ignores slimes from mob spawners
  4. Detects if the world is Superflat using chunk generator analysis

If all conditions are met, the slime is immediately removed from the world. This approach ensures compatibility with all Superflat presets, including custom world generation configurations.

For detailed technical information, see the Technical Documentation page.
