NoMonsInMyWorld

NoMonsInMyWorld is a lightweight but powerful server-side utility for Cobblemon that gives you precise, per-world control over both Pokémon spawning and riding. Whether you need to create a Pokémon-free hub, ban specific species from a dimension, or prevent players from riding legendaries in certain worlds, this mod provides a simple, config-driven solution.

Dependencies

• Fabric API
• Fabric Language Kotlin
• Cobblemon
• E-Utils

Features

• Per-World Spawning Rules: Create unique spawning rules for each dimension. Completely disable spawning in your hub, allow only specific types in another, and leave the main world untouched.
• Advanced Spawn Filtering: Block Pokémon using simple species names (e.g., cobblemon:zubat) or use powerful conditions to filter by type (type=flying), rarity (legendary=true), or attribute (shiny=true).
• Per-World Riding Rules: Independently control which Pokémon can be ridden in each dimension. Completely disable riding in event worlds or blacklist specific powerful mounts from your survival worlds.
• Owned Pokémon Protection: A smart filter allows players to send out their own Pokémon, even in dimensions where wild spawns of that species are disabled.
• Live Reload: A simple command lets you apply configuration changes instantly without needing a server restart.
• 100% Server-Side: No installation is required for players to join your server.

Commands

The mod is designed to be managed primarily through its configuration file, with a single command for convenience.

Configuration

NoMonsInMyWorld uses a single, easy-to-understand configuration file located at config/nomonsinmyworld/config.json. The entire configuration is managed within a worlds object, where you can add an entry for each dimension you want to control.

Example Configuration

    // Rules for a hub world (e.g., from another mod)
    "some_mod:hub_world": {
      "spawning": {
