About this project

What does Oh My World add?

Turn mathematical expressions into world generation.

Oh My World is a NeoForge mod for Minecraft 1.21.1 that lets you define terrain using a powerful expression engine. Write formulas with arithmetic, trigonometry, and function defined by yourself — and watch them transform into infinite custom landscapes.

What You Can Create

Endless checkerboard patterns — alternating blocks in any grid size
Mathematical function graphs — sine waves, circles, spirals rendered in blocks
3D models and structures — cyclic layers stacked with precision
Randomized block pools — procedural variety with seeded determinism
Anything you can express — the expression engine supports 23 functions

Built-in Expression Engine

Arithmetic、Comparison、Math、Trigonometry etc.

For more details, please refer to the formula writing guide.

How to Use

Create a new world → World tab → World Type → select Formula Generator
Click Customize to open the formula editor
Enter your formula and a save name, then click Done
Create the world — every chunk follows your rules

A comprehensive formula writing guide is automatically created in on first launch. The specific location will be indicated above the formula input box.

It is recommended to set "Generate Structures" to OFF when the top layer of your pattern is not a flat, continuous surface.
