No Slime Superflat

No Slime Superflat is a simple utility mod for Minecraft that prevents slimes from spawning in Superflat world

Features

  • Slime Prevention: Automatically stops slimes from spawning in worlds detected as "Superflat"
  • In-game Configuration: You can enable or disable the mod's functionality through the config menu without restarting the game
  • Custom Blacklist: Adds an option to include other entity IDs that you want to block from spawning in Superflat worlds
  • Basic Statistics: Includes a command (/noslimesuperflat stats) to see how many spawns have been prevented in the current session

Technical Details

  • Standalone: This mod does not require Collective or any other library to function
  • Logic: The mod checks the world type and entity type before canceling a spawn event. It includes a basic internal timer to limit how often it checks the world type

How to Use

  1. Install the mod in your mods folder.
  2. Start the game. Slimes will no longer spawn in Superflat worlds by default
  3. Use /noslimesuperflat reload if you manually edit the configuration file
