FallMobs is a lightweight Minecraft Forge mod that gives you permanent control over which mob types exist in your world. Deleted mobs are blocked from spawning and existing ones are removed instantly.

Why use FallMobs?

Ever wanted to get rid of a specific mob permanently? Maybe you're tired of creepers destroying your builds, or you want a world without phantoms. FallMobs lets you delete any mob type with a single command or click. The deletion is persistent — even after restarting the world, those mobs will never spawn again.

Commands

/fallmob delete <entity> — Permanently delete a mob type (e.g. /fallmob delete creeper)
/fallmob restore <entity> — Restore a previously deleted mob type
/fallmob list — Show all currently deleted mob types
/fallmob help — Display usage information

GUI

Press L to open the management screen. Browse a searchable list of all living entity types, click to select, then press Delete or Restore. The interface updates in real-time.

How it works

The mod hooks into entity spawn events at the highest priority. When an entity tries to spawn, FallMobs checks if its type is in the deleted list and cancels the spawn if so. Existing entities are removed immediately using Minecraft's native entity removal system. All data is stored per-world using Minecraft's SavedData system.
