FixedMathSharp-Unity

Unity package host for FixedMathSharp.

This repository contains two installable Unity Package Manager variants:

• com.mrdav30.fixedmathsharp
• com.mrdav30.fixedmathsharp.lean

Both packages provide the same core deterministic fixed-point math library and Unity interop helpers. The difference is whether the package includes MemoryPack.

Which Package Should I Use?

com.mrdav30.fixedmathsharp

Standard package with MemoryPack support enabled.

Install:

https://github.com/mrdav30/FixedMathSharp-Unity.git?path=/com.mrdav30.fixedmathsharp

Use it when:

• You want the default package.
• You want the built-in MemoryPack serialization path.
• Burst AOT compatibility is not your main concern.

com.mrdav30.fixedmathsharp.lean

Package without MemoryPack.

Install:

https://github.com/mrdav30/FixedMathSharp-Unity.git?path=/com.mrdav30.fixedmathsharp.lean

Use it when:

• You use Unity Burst AOT.
• You want the safer choice for Burst-oriented builds.
• You want to avoid the MemoryPack dependency.
• You plan to use your own serialization stack.

Why Two Variants?

If you use Unity Burst AOT, prefer the Lean build. MemoryPack's Unity support is centered on IL2CPP via its .NET source-generator path, so the no-MemoryPack variant is the safer choice for Burst AOT scenarios.

What Both Packages Include

• Deterministic fixed-point math via Fixed64
• Core math, trigonometry, vectors, quaternions, and matrices
• Bounds and geometry helpers
• Unity transform, matrix, and bounds interop
• Editor helpers and sample content

Notes

• This repository is currently intended for Git URL installation rather than an official package registry.
• Each package has its own README.md with package-specific installation guidance.
