The Ruler Mod (1.21.10, 1.20.1) – Lock Any Game Rules In All Saves

The Ruler Mod allows players and modpack creators to set and lock default game rules across all saves, including modded worlds. By editing a single JSON config file in the .minecraft/config folder, you can enforce rules like disabling daylight cycles (doDaylightCycle: false) universally. This eliminates the need to manually adjust gamerules in every new world, making it ideal for modpacks, servers, or players wanting consistent settings.

Features:

• Forces specified gamerules (vanilla or modded) to apply to all saves upon world load, overriding per-world defaults.
• Edit the_ruler.json with key-value pairs (e.g., “doDaylightCycle”: false), create the file if missing, then /reload (servers) or rejoin the world.
• Minimal overhead, no in-game UI or commands needed beyond standard reload/rejoin.
