Mob Limiter

This mod lets you control mob spawning by setting per-chunk and world limits, helping to prevent overcrowded farms or excessive mob spawns.

Features

• Chunk Limits: Restrict mob counts per chunk to avoid overcrowding.
• World Limits: Set global caps for total mob populations.
• Targeted Limits: Apply restrictions to specific mobs, categories, or namespaces.
• Modded Mobs: Supports mobs registered in Forge.
• Excess Handling: Remove excess mobs via silent despawn or kill with loot and experience.
• Despawn Control: Choose vanilla rules, custom despawn ranges, or persistent mobs.
• Commands:
  • /moblimiter reload: Refresh config without server restart.
  • /moblimiter info: Display active settings.
• Priority System: Limits prioritize specific mobs, then categories, namespaces, and defaults.
• Optimized: Asynchronous processing ensures smooth server performance.

Configuration

Customize limits and despawn behavior in config/moblimiter.json5. Example:

{ // Vanilla despawn settings // mode: "vanilla" (default rules), "custom" (set min/max distance), "disabled" (persistent mobs) "vanilla_despawn": { "mode": "custom", "min_distance": 32.0, // Min distance (blocks) to despawn (for "custom" mode) "max_distance": 128.0 // Max distance (blocks) to despawn (for "custom" mode) }, // World-wide mob limits // enabled: true/false to toggle world limits // total: Max mobs in the world (-1 for unlimited) // removal_type: "despawn" (silent) or "kill" (drops loot) "world_limits": { "enabled": true, "total": 500, // Total mobs allowed in the world "removal_type": "despawn", "mobs": { "minecraft:cow": 100, // Max 100 cows in the world "minecraft:pig": 100, // Max 100 pigs in the world "minecraft:zombie": 50 // Max 50 zombies in the world } }, // Per-chunk mob limits // enabled: true/false to toggle chunk limits // default.limit: Default mob cap per chunk (-1 for unlimited) // removal_type: "despawn" (silent) or "kill" (drops loot) "chunk_limits": { "enabled": true, "removal_type": "despawn", "default": { "limit": 20 }, // Default limit for unspecified mobs "mobs": { "minecraft:cow": 10, // Max 10 cows per chunk "minecraft:pig": 10, // Max 10 pigs per chunk "minecraft:chicken": 10, // Max 10 chickens per chunk "minecraft:creatures": 15, // Max 15 creatures (animals) per chunk "minecraft:*": 8 // Max 8 of any other Minecraft mob per chunk } } }

Usage

Follow these steps to set up and use Mob Limiter:

1. Install the Mod:
   Add Mob Limiter to your server (client installation is optional). The mod is server-side and works without requiring clients to install it.

2. Configure Limits:
   After launching the server, find config/moblimiter.json5 in the server directory. Edit the file to set your desired limits and despawn behavior (see the example above). Save the file after making changes.

3. Apply Changes:
   Run /moblimiter reload in-game or via the server console to apply changes without restarting.

4. Check Settings:
   Use /moblimiter info to view the current configuration, including despawn mode, world limits, and chunk limits.
