Boring Default Game Rules

by Ennui

Boring Default Game Rules lets a server owner change the default values that new worlds start with for each vanilla game rule, without editing files by hand.

FabricQuiltServer-side onlyMIT LicenseOpen source1.17 – 1.21.8

What it does

Two methods edit the defaults. The main one is the Edit Default Game Rules screen, reached from a control on Vanilla's Game Rules screen or from the mod's config control on the Mod Menu list. In that screen, changing a value works like changing a rule in a regular world, and a Defaults control at the bottom resets the list. The second route is an offline JSON file, which carries a commented format and a JSON Schema describing each option, so the values can be edited outside the game.

Boring Default Game Rules requires Fabric API, and it runs on Fabric Loader or Quilt Loader. It needs Minecraft 1.20.6 or later for the default-edit screens described here, and files are published for 1.17 – 1.21.8 across 22 release versions. The mod is server-side only, so players join without installing it, and the code is released under the MIT License as open source. Mod Menu is optional and adds the config control.

Key features

  1. Default rules screen

    A screen lists every vanilla game rule and lets the server owner set the value that new worlds will use.

  2. Vanilla rules screen control

    An added control on the Game Rules screen opens the defaults editor from inside a world.

  3. Config screen

    The config screen allows off-game configuration, and it generates a JSON Schema for the options.

  4. Reset to defaults

    A Defaults control at the bottom of the list restores the vanilla values for every rule at once.
