ToolsJS

by Bluemethyst

ToolsJS is a NeoForge library for defining new tool items through KubeJS scripts, so modpack authors can add tools without writing Java.

What it does

The mod works as an addon for KubeJS and lets scripts create tools. Its built-in texture model files are copies of the vanilla ones, so a custom item can reuse the same model file names as the vanilla versions. Example horse armor and a custom crossbow with their own textures show the approach. Textures for the examples come from FooterManDev, and mcasset.cloud is named as a source for finding the vanilla model files. Kotlin for Forge and KubeJS are required, and Ex Deorum is optional for tool use.

Key features

  1. Scripted tool types

    Scripts can register new tool types, so each tool gets its own behavior and stats.

  2. Custom item textures

    Custom items can use textures and model files that match the vanilla naming, shown by the horse armor and crossbow examples.

  3. Ex Deorum integration

    Tools can be set up to work with Ex Deorum when that optional mod is installed.

Questions

Does ToolsJS need KubeJS?

Yes. KubeJS and Kotlin for Forge are both required, so both must be installed next to ToolsJS.
