FixedMathSharp-Unity

API Documentation

Unity package host for FixedMathSharp. Both variants contain the same deterministic math library and Unity math, geometry, bounds, and transform adapters.

Standard

com.mrdav30.fixedmathsharp includes the MemoryPack serializer/runtime integration.

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

Lean

com.mrdav30.fixedmathsharp.lean omits the MemoryPack serializer/runtime and is the safer default for Burst AOT. It includes only Chronicler.MemoryPackShim.dll, an attribute-shape compatibility assembly required by the Lean core DLL; it does not serialize data.

Included

• Deterministic Fixed64 math, vectors, quaternions, matrices, bounds, frustums, curves, and geometry
• Unity vector, ray, plane, rectangle, bounds, matrix, AnimationCurve, and FixedTransform interop
• Fixed-point inspector drawers and a sample scene

Plane[] planeBuffer = new Plane[FixedBoundFrustum.PlaneCount];
FixedBoundFrustum frustum = camera.ToFixedBoundFrustum(planeBuffer);

if (!animationCurve.TryToFixedCurve(out FixedCurve curve))
    curve = animationCurve.BakeToFixedCurve(65);

BakeToFixedCurve is an explicit floating-point approximation. Bake once at an authoring/loading boundary and distribute or persist the fixed keys; lockstep peers should not bake independently.
