NoMonsInMyWorld

NoMonsInMyWorld is a lightweight, server-side Minecraft Fabric mod for Cobblemon that gives you per-world control over Pokémon spawning. Block specific species, filter by type/shiny status, or completely disable spawns in hub worlds, minigame maps, or curated dimensions.

Features

Per-World Spawning Control

• Species Blacklists: Block specific Pokémon by ID in any world (e.g., cobblemon:rattata)
• Advanced Conditions: Filter by type (type=ghost), shiny/legendary status (shiny=true), or any Pokémon property
• Global Spawn Toggle: Disable ALL Cobblemon spawns per-world with one config option
• Owned Pokémon Filter: Allow player-owned Pokémon to be summoned even in worlds where wild spawns are blocked

Per-World Riding Control (New!)

• Dimension-Specific Bans: Completely disable the ability to ride Pokémon in specific worlds (perfect for spawns or hubs)
• Mount Whitelisting/Blacklisting: Prevent players from riding specific species (e.g., ban cobblemon:charizard in the Overworld)
• Conditional Riding: Restrict riding based on properties (e.g., prevent riding legendary=true Pokémon in survival worlds)

Simple JSON Configuration

• Automatic config versioning and backup (no manual migration needed)
• Live reload support
• Clear syntax: use species IDs, property filters, or boolean flags

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

{
  "version": "1.0.0",
  "worlds": {
    // Rules for the Overworld
    "minecraft:overworld": {
      "spawning": {
        "disallowedSpecies": ["cobblemon:rattata", "cobblemon:pidgey"],
        "exclusionConditions": ["type=ghost", "shiny=true"],
        "disableAll": false,
        "excludeOwnedPokemon": true
      },
      "riding": {
        "disallowedSpecies": ["cobblemon:charizard"],
        "exclusionConditions": ["legendary=true"],
        "disableAll": false,
        "excludeOwnedPokemon": false
      }
    },
    // Rules for a hub world (e.g., from another mod)
    "some_mod:hub_world": {
      "spawning": {
        "disableAll": true, // Master switch to block all wild spawns
        "excludeOwnedPokemon": true // Still allows players to send out their own Pokémon
      },
      "riding": {
        "disableAll": true // Master switch to block all riding
      }
    }
  }
}
