FixedMathSharp for Unity v7.0.0

This major release upgrades both Unity package variants to FixedMathSharp 7.0.0 and expands the Unity adapter layer with clearer, deterministic math, geometry, bounds, transform, frustum, and curve interop.

Highlights

• Added Unity camera and projection-matrix conversion to FixedBoundFrustum, including caller-owned plane buffers for allocation-conscious workflows.
• Added exact Unity AnimationCurve → FixedCurve conversion, explicit sampled baking for unsupported curves, and FixedCurve export back to Unity.
• Expanded interop for Vector4d, rays, planes, rectangles, bounds, matrices, and FixedTransform hierarchies.
• Corrected matrix conversion between Unity's column-vector convention and FixedMathSharp's row-vector convention.
• Added atomic Try* conversions and transform application that safely reject semantic loss or leave targets unchanged.
• Improved Unity serialization coverage for non-zero Fixed64, Vector2d, Vector3d, and Vector4d values in ScriptableObjects and prefabs.
• Published a searchable DocFX API reference and package changelog.

Breaking changes

• Vector and bounds projections now use explicit XY/XZ names such as ToVector2dXY, ToVector3dXZ, and ToFixedBoundAreaXZ.
• Transform factory methods now use CreateTransform*; removed 3×3 rotation-scale transform helpers are replaced by FixedTransform components or strict Fixed4x4 application.
• Fixed-to-Unity rays and matrix/transform application now reject non-unit directions, shear, perspective, singular matrices, and unrepresentable hierarchy conversions instead of silently normalizing or partially mutating state.
• Matrix conversions now transpose elements to preserve transform semantics. Audit code that depended on the previous direct-copy layout.
• FixedMathSharp 7.0.0 contains additional core breaking changes; review the migration guide before upgrading.

FixedMathSharp-Unity v5.0.1

Fixed64 Unity Serialization Fix

Fixed Unity persistence for Fixed64-backed authoring fields.

Unity does not serialize readonly fields, so Fixed64 values backed by a readonly long could be edited in the inspector but reload as zero from assets or prefabs. Fixed64 now uses a Unity-compatible raw-value field layout while remaining engine-agnostic and wrapper-free.

Verified

• Fixed64 persists through ScriptableObject assets and prefabs.
• Vector2d and Vector3d persist correctly.
• Nested structs containing Fixed64 persist correctly.
• List<T> elements containing Fixed64 and Vector3d persist correctly.
• Existing fixed-point behavior and raw-value representation are unchanged.

FixedMathSharp-Unity v5.0.0

This release updates both Unity Package Manager variants to FixedMathSharp 5.0.0 and aligns the Unity adapters with the core v5 API and coordinate semantics.

Breaking Changes

• Updated the embedded FixedMathSharp binaries and XML docs to v5.0.0.
• Unity adapter code now follows the core v5 naming model, including PascalCase vector, quaternion, bounds, and matrix members such as X/Y/Z, W, and M11-style matrix fields.
• Matrix and transform conversions now use explicit semantic mapping between FixedMathSharp row-vector matrices and Unity transforms, including translation mapping between FixedMathSharp M41/M42/M43 and Unity m03/m13/m23.
• Removed the old standalone Matrix4x4.Extensions.cs and Transform.Extensions.cs organization; those helpers now live with the fixed-type extension surfaces.

Highlights

• Added clearer Unity/FixedMathSharp coordinate semantics: +X right, +Y up, and +Z forward are preserved across vector, quaternion, matrix, and transform conversions.
• Added explicit XY and XZ vector projection helpers for 2D/3D Unity interop.
• Added Unity-to-fixed transform round-trip helpers, including local/world Transform -> Fixed4x4 -> Transform workflows.
• Hardened inspector drawers for FixedMathSharp v5 serialization, including fixed number, vector, matrix, quaternion, and angle/rotation drawers.
• Renamed and refreshed bounds interop around FixedBoundBox and FixedBoundArea.
• Added EditMode tests covering vector projections, coordinate conventions, matrix translation semantics, and transform round trips.
• Added package version sync tooling and refreshed developer guidance for maintaining the base package source and generated UPM variants.

FixedMathSharp-Unity v4.0.0

Breaking

• Upgraded to FixedMathSharp v4.0.0.
• Moved all *Drawer classes under Editor/Drawers to ease sync management

Internal

• Added tooling to support multiple packages that share the same base

FixedMathSharp-Unity v3.0.2

This update only impacts the "No-MemoryPack" variant

What's New

• changed com.mrdav30.fixedmathsharp.nomemorypack to com.mrdav30.fixedmathsharp.lean
  • updated asmdef to use unique name to avoid confusion between standard package
