Goop Forge

by Xyndra

Goop Forge is a Forge library for puddle and goop effects, with a data-driven emitter API that lets authors define their own.

ForgeClient and serverMIT LicenseOpen source1.20.1 – 1.20.6

What it does

Goop Forge is a fork of Goop for Forge 1.20.1. Its emitters are configured with JSON files, so a resource pack can add new goop effects without Java code. The mod adds entity interactions with goop, a set of optional built-in effects, and an improved rendering pass, with puddle drip scale that changes smoothly rather than jittering. Surface detection for puddle placement was made more accurate, and the underlying calculations were optimized.

Other mods that need goop effects can depend on Goop Forge instead of bundling their own goop code. Goop Forge is a Forge library, and it runs on client and server, so the server and every player need it. Builds cover 1.20.1 – 1.20.6 with six release versions, and the code is open source under the MIT License. The latest Forge file, 0.4.3-1.20.1-2, targets 1.20.6.

Key features

  1. Data-driven emitters

    Emitters are defined in JSON files, so resource packs can register new goop types and behaviours.

  2. Entity interactions

    Goop can affect entities that touch it, and the mod adds several optional built-in effects for them.

  3. Puddle placement

    Surface detection for puddles is more accurate, so puddles sit on the right blocks and follow walls and ceilings.

  4. Smoother rendering

    Goop faces are drawn with improved rendering, and puddle drip scale changes smoothly.

Use cases

Mod developers

Resource pack authors

Packs can add custom emitters with simple JSON files, without writing Java.

Who it’s for: Mod developers building goop or liquid-like effects for Forge 1.20.1 and later builds, and resource pack authors who want custom goop behaviour without code.

What the author says

This is a fork of Goop for 1.20.1 Forge. Now, add a goop_emitters directory in your namespace directory. In there you can put your Emitter JSON files; and that's already it! For in-depth documentation on how to write emitters, please check here. You can also double-check with the builtin packs since compatibility…
