Description

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

Performance & Safety

  • 100% Server-Side: No client mods required
  • Zero Tick Overhead: Event-based, runs only when Cobblemon tries to spawn
