EtSTLib

by EtSH-C2H6S

EtSTLib is a Forge library for addons built on the Tinkers' construction mod family, providing a small set of hooks, modifiers and helper code.

ForgeClient and serverMIT License1.20.1

What it does

The library collects a modest number of hooks, modifiers and supporting code that the author plans to reuse in later projects. Modpack makers and developers writing addons for this family can read it as a working reference for how the pieces fit together.

It relies on Mixin, which can cause conflicts with other mods. Both the server and every player need it, and it is released under the MIT License without being open source. Files target 1.20.1 only, with 3.0.0-beta.20 as the latest Forge build from 2026-04-10. Tinkers' Advanced requires it.

Key features

  1. Addon hooks

    Hook points that addon code can attach to when extending the tool and armor system.

  2. Modifiers

    Modifier definitions that tools and armor can use, implemented as part of the library.

  3. Developer reference

    Code that addon authors and modpack makers can study to see how the library's pieces are wired together.
