About this Mod
Fluid Skills
A library mod to control how players see and interact with fluids using skill-based rectrictions created in KubeJS
scripts. This is similar to Ore Stages, but it targets fluids instead of blocks and interacts with JEI/REI for hiding
recipes that use fluids, complementing Item Skills.

Concepts
This mod leans extensively on Player Skills by creating and consuming the Skill-based Restrictions. Out of the box, this
mod can restrict whether a fluid can be removed from the world, crafted, visible in JEI or REI, and whether it can
be identified in a tooltip. It also provides a way to mask fluids in world by replacing them with either air or another
fluid (e.g. make all crude oil appear and function as lava). Lastly, this mod also provides a way to manipulate
fluid finitiude (e.g. make water finite or make lava infinite).
Caveats
- Adding a replacement restriction on common fluids (i.e. turning water in the Overworld into lava or similarly with
lava in the Nether) can cause a lot of lag in Forge on skills change which could kill single player instances without
enough memory. - We can only prevent picking up a fluid with
unbucketablebecause we are not guaranteed access to know what's in
the bucket and whether it contains anything without sacrificing working with bucket-like items from mods. To prevent
placing a fluid, use Item Skills restrictions on the bucket item. - To see replacements in world, Block Skills must be installed.
- JEI integration does not remove recipes related to the
unconsumableflag. It does hide the recipes from
right-clicking on the ingredient. However, it does not remove the recipe itself -- onlyunproducibledoes that.
That is, a crafty player could view a recipe that produces the item, then right click on the produced item to see
what recipes with which it can be consumed.
