LibGamerule

Libgamerule allows for easily adding custom gamerules on the Fabric modloader.

Usage (for mod devs)

// Adding a boolean gamerule GameRules.RuleKey<BooleanRule> MY_GAMERULE = Gamerule.register( "myGameRule", // name in /gamerule BooleanRule.create(true) // default to true ); // Get the gamerule data boolean value = Gamerule.get(MY_GAMERULE);

Supported Rule types:

BooleanRule
DoubleRule (+min/max)
IntRule (+min/max)
EnumRule (Any Enum)
StringRule (greedy strings)

Libcd support (datapack/modpack devs)

Conditions (note: does not support enums)

{ "when": [ { "comment": "Boolean gamerule check", "libgamerule:gamerule_has_value": "my_gamerule" }, { "comment": "Typed gamerule check", "libgamerule:gamerule_has_value": { "name": "my_gamerule_typed", "type": "int", "value": 10 } } ] }

Creating gamerules in scripts

var GameruleTweaker = libcd.require("libgamerule.GameruleTweaker"); GameruleTweaker.addGamerule("my_gamerule", "boolean", false); GameruleTweaker.addGamerule("my_gamerule_typed", "integer", 7);
