Description

Difficulty Lock adds an easy way to configure the difficulty in all (new) worlds. Can be useful for modpacks, or just in your singleplayer experience if you have a default difficulty you always play with. There are config options to force the Hardcore gamemode, disable cheats, or prevent Creative mode from being selected.

The Create World Screen is correctly updated with the config settings. Also works on (dedicated) servers.

Environment: Server

All available config options:

The priority shows how the mod handles when multiple gamemodes are set to true in the config. E.g. if all are enabled all new worlds will be peaceful.

forceHardcoreMode  default false
Sets the world game mode to hardcode mode and ignores the other difficulty settings when enabled.

disableCreativeModeSelection  default false
Whether Creative Mode should not be possible to select in the world creation screen.

forcePeaceful  default false
Priority 1: Sets the difficulty in any world to peaceful when enabled.

forceEasy  default false
Priority 2: Sets the difficulty in any world to easy when enabled.

forceNormal  default false
Priority 3: Sets the difficulty in any world to normal when enabled.

forceHard  default true
Priority 4: Sets the difficulty in any world to hard when enabled.

forceCheatsDisabled  default false
Whether the cheats option should be forced to be disabled on the initial world creation screen.

shouldLockDifficulty  default true
When enabled, locks the difficulty in any world so it cannot be changed.

shouldChangeDifficultyWhenAlreadyLocked  default false
When enabled, also sets the difficulty in worlds where it has already been locked.

With the default configuration, all worlds will be set to hard with the difficulty locked:

The Create World Screen is also updated.
Here the config options forceHard and forceCheatsDisabled are true:

The mod also allows users to be forced to play in Hardcore Mode, via the config:

You may freely use this mod in any modpack, as long as the download remains hosted within the CurseForge or Modrinth ecosystem.
