ikbLib
An API for density functions that use the world seed, voronoi/cellular noise, and new fluid behaviors
About this Mod
ikbLib is a library mod featuring a family of new voronoi/cellular noise density functions, plus API for seeded density functions and new fluid behaviours. For full documentation, see the Wiki.
Voronoi Noise

If you were to drop many different colors of paint onto a canvas, then let each color spread from the point where it falls, you would get a kind of image called a voronoi diagram. These diagrams are the basis of voronoi noise, also called cellular noise because it resembles a microscopic view of plant or animal cells.
ikbLib adds three new density functions that this type of noise:
"ikblibrary:voronoi": A basic voronoi noise function, which can output the distance from center, value, or velocity of the current cell or a neighboring cell. A defined"scale"parameter is required, but all other parameters are optional and revert to default if omitted."ikblibrary:cached_voronoi"&"ikblibrary:pull_cached_voronoi": A pair of technical functions. These have the same outputs and configurations as the basic voronoi noise, but are optimized for sampling several different values from a single voronoi diagram.
Seeded Density Functions
ikbLib adds a new interface called SeededDensityFunction which other mod developers can use to easily pass the world's seed into their own density functions. See the Wiki or Github repository for implementation details.
Stackable Fluids
ikbLib creates a simple, data-driven* system for making fluids that flow under and over other fluids. Simply add the stackable_wet or stackable_molten tag to a group of fluids, and watch them stack!

*For full effectiveness, ensure each fluid has a defined density in NeoForge's fluid API. When two fluids meet, the denser of the two will flow through and under the lighter fluid.

ikbLib server crashes on startup – what to do?
Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.
Is ikbLib compatible with neoforge?
ikbLib officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with ikbLib – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if ikbLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
