Description

A No Name Provided mod

TLDR

You know how you can have a water block with other things (stairs, slabs, etc.) in it? Now you can do that with any fluid. This mod is now feature complete.

About This Mod

Have you ever wondered why you can't pour lava into some stone stairs? Or use that nice looking modded fluid to add a pretty channel to your road? Well, I won't bore you with the answer. Long story short, this is a basic, "naive" approach to jailbreaking the vanilla fluidlogging system. These early releases are intended to get the ball rolling and give other devs something to contribute to, but the mod is ready for useage by map makers and regular players who aren't worried about a ittle jank.

If you're interested in fluid logging, but intimidated by the idea of making a mod from scratch, consider taking a look at the repo and contributing performance and/or bug fixes.

More Info

This mod is compatible with most fluids out-of-the-gate. Don't worry, it has a configurable blacklist.

This mod uses many mixins. This means it's more likely to conflict with other mods. If there's a mixin error in your log, it's a cross-mod compat issue and should be reported to both developers. In the meantime, you can resolve the issue by removing one of the conflicting mods.

LTS versions are available here, and may even be up-to-date. However, I despair at the thought of trying to upload every minor version through the Modrinth GUI - those can be found on CurseForge. There is a functional release available for every (release) version of Minecraft since 1.21.1 and a corresponding branch in my repo, if you want to make pull requests.

Help for Devs

One feature isn't automatic - if you want flowing fluids to respect a custom loggable block's geometry, you're going to have to add it to the fluid_level_limits DataMap. Modders can register additional callbacks for complex blocks, but anything with slab, stair, or constant-height geometry is supported natively - just add the block to the datamap with the same entries used for its closest vanilla counterpart.
