Difficulty Lock (Legacy Fabric) - Difficulty Locking in Minecraft

This minimalist mod provides an easy way to configure the difficulty level in all new Minecraft worlds. Perfect for modpacks or singleplayer gameplay if you prefer a specific default difficulty level.

Configuration Settings

The mod offers flexible settings for managing difficulty. Priority determines how conflicting settings are handled - for example, if all modes are enabled, new worlds will be created on peaceful difficulty.

forcePeaceful (default = false): Priority 1 - sets difficulty of any world to peaceful

forceEasy (default = false): Priority 2 - sets difficulty of any world to easy

forceNormal (default = false): Priority 3 - sets difficulty of any world to normal

forceHard (default = true): Priority 4 - sets difficulty of any world to hard

shouldLockDifficulty (default = true): Locks difficulty in any world, preventing its change

shouldChangeDifficultyWhenAlreadyLocked (default = false): Allows changing difficulty in worlds where it was already locked

With default settings, all worlds will be created on hard difficulty with locked change capability:
