Unlimited Fluidity
by Forsteri123
Unlimited Fluidity is a Forge library that extends how fluids behave, adding properties for sponging, swimming, viscosity and gases to the fluid system.
What it does
Unlimited Fluidity gives fluid blocks extra behavior beyond the standard Forge fluid system. Sponges can absorb or be blocked from absorbing specific fluids, a fluid can be set to allow swimming, and a fluid's viscosity can slow the player's movement. The mod also includes a gas system, so fluids that behave as gases can be modeled alongside liquids.
The mod is a library, so it adds no items to play with on its own. Other mods use its additional fluid properties, and two catalog mods require it: Create: Industrial Chemistry and Create: Petrol Powered. Unlimited Fluidity runs on client and server, so the server and every player need it. It is published for Forge on 1.18.2 only, released under the MIT License, and the source code is open source.
Key features
Sponge interaction
Fluids can be given sponge rules, so a sponge can absorb them or refuse to, depending on the fluid's settings.
Swimmable fluids
A fluid can be flagged as swimmable, letting players move through it the way they move through water.
Viscosity and movement
Each fluid can carry a viscosity value that changes how quickly the player moves while inside it.
Gas system
A gas layer lets fluids behave as gases, with their own handling separate from liquid fluids.

Use cases
Custom chemical fluids
Modpacks that add chemistry or oil processing can give their fluids sponge rules, swimming or viscosity without writing the logic themselves.
Gas handling
Machines or pipes that move gases can use the gas system instead of treating gases as ordinary liquid fluids.
Who it’s for: Mod developers building fluid content for Forge 1.18.2, and modpack authors who combine fluid-based machines from other mods with custom fluid behavior.

This an library for additional properties and systems on fluids. \ This might be superset of Forge Fluid System Update for only 1.19.2 in the future.
