Crusher Recipe Registration

The Crusher supports dynamic recipe registration using ScriptEvents.
Recipes are sent as a JSON string after worldLoad, and UtilityCraft parses and registers them automatically.

Sending the ScriptEvent​

import { system, world } from "@minecraft/server";

const newRecipes = {
    "minecraft:stone": {
      output: "minecraft:cobblestone",
      amount: 1
    }
};

world.afterEvents.worldLoad.subscribe(() => {
  system.sendScriptEvent(
    "utilitycraft:register_crusher_recipe",
    JSON.stringify(newRecipes)
  );
});

You must always:

  • Wait for worldLoad
  • Use JSON.stringify
  • Send through utilitycraft:register_crusher_recipe

Recipe Object Fields​

Crusher, Incinerator, and Electro Press share the same fields:

  • output (required)
    Item produced by the machine.

  • amount (optional, default: 1)
    Number of output items produced per operation.

  • required (optional, default: 1)
    Amount of input items required per operation.

  • cost (optional, default: 800 DE)
    Energy cost per operation.

If optional fields are omitted, machine defaults are applied automatically.

  • tier (optional)
    Minimum Hammer tool tier required to crush the block when breaking it manually.

Example Recipe Object​

const recipes = {
  "minecraft:stone": {
    output: "minecraft:cobblestone",
    amount: 1,
    cost: 1000,
    tier: 1
  }
};

Notes​

  • If a recipe already exists, it will be replaced.
  • Invalid fields are ignored safely.
  • Recipes are registered at runtime and do not require modifying UtilityCraft source files.
