Unity.Mathematics

[1.2.5] - 2021-11-01

Fixed

• Fixed property drawing when manually drawing a property that was hidden with [HideInInspector].

Added

• Added [Il2CppEagerStaticClassConstruction] to Unity.Mathematics types to run static constructors at startup. This improves IL2CPP performance slightly for types that have static constructors.

Changed

• License file updated to satisfy Unity's package validation tests.
• Changed noise documentation in comments to xmldoc comments.

Deprecated

Removed

Fixed

• Fixed Equals(object) override which did not check type before casting. This could cause exceptions to be thrown when the object did not match the expected type.
• Fixed incorrect math.tzcnt documentation which mentioned leading zero counts instead of trailing zero counts.
• Fixed float2x2.Rotate documentation to mention radians instead of degrees.
• Fixed documentation for methods and properties that were previously undocumented.

Conforms to documentation standard, without introducing new APIs

• Added [MethodImpl(MethodImplOptions.AggressiveInlining)] to many static functions to improve IL2CPP performance.
• Added compress() that accepts a float4 and uint4.
• Added math.project() and math.projectsafe() for vector projection.
• Added math.EPSILON, math.INFINITY, math.NAN and their double counterparts.
• Added [Serializable] to RigidTransform.
• Added math.ceillog2().
• Added math.floorlog2().
• Added math.down(), math.forward(), etc for Cartesian coordinate axes that match UnityEngine Vector3 equivalents.
• Added math.ispow2().
• Added half.MinValueAsHalf and half.MaxValueAsHalf to avoid having to explicitly convert from float.
• Added a float3x3 constructor which takes a float4x4 as input.
• Added [Serializable] to half types.
• Added some performance tests which can be run from the Unity test project.
• Added Random.CreateFromIndex() to assist in creating Random instances from loop indices.
• Fixed documentation bug where quaternion.RotateX/Y/Z referred to a float4x4 instead of quaternion.
• Fixed code generation bugs which could cause Windows and Mac to generate different test code.
• Fixed some test asserts which used NaNs and signed zeros which failed in IL2CPP builds.
• Updated documentation for math.countbits() to include equivalent names on Intel and ARM architectures to aid in discoverability.
• Fixed warnings for meta files existing even though the files they represent did not exist.

Release stable package

• Add new math.bitmask to return a bit mask from a bool4

• Fixed bug where modifications on prefabs could not be reverted for vector properties when using context menu in Inspector.

• Fixed structure of the package for internal validation

This release will not publish a package

• Improve test coverage
• Improve documentation
• Vectorized implementation of float3x3 inverse
• Fixed bugs in PostNormalizedVectorDrawer
  • Fixed exception when drawing control without having called GetPropertyHeight first
  • Apply normalization twice to fix possible precision error (fixes issue where value might be normalized with magnitude slightly less than 1)
  • Fixed bug where stale post-normalized values were applied to property when it was edited from another context (fixes issue where systems could not modify an entity's rotation while it was inspected)
• Misc bug fixes

Property Drawer Refinements and NaN fix for LookRotationSafe
