Chaotic Randomness
by Gl1tcherBro
Chaotic Randomness is a Fabric Cursed mod that alters some math values, so the numbers behind the game produce unexpected results.
What it does
The mod changes several mathematical values in the game, which produces a range of odd effects. It swaps the sin and cos functions and changes how Gaussian Perlin noise is applied, so terrain and other noise-driven output can look unusual. It runs on client and server, so both sides need the mod. The Fabric file targets 1.21.1 only, released 2024-10-17, and the source code is public under CC0 1.0 Universal, which places it in the public domain.
Key features
Altered math values
Several mathematical values in the game are modified, which leads to strange behavior in gameplay.
Swapped sin and cos
The sin and cos functions are exchanged, changing how any code relying on them calculates results.
Changed Perlin noise
The way Gaussian Perlin noise is used is altered, so noise-based generation takes an unfamiliar shape.
