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.
