unity-physicscore2d-destructor-api

Use PhysicsDestructor.Fragment with a FragmentGeometry target and a ReadOnlySpan of world-space fragment points. The method returns a FragmentResult containing broken and unbroken geometry, which must be disposed after use to avoid leaks.

Call PhysicsDestructor.Slice with the target FragmentGeometry, an origin point, and a non-zero translation vector defining the slice ray. The SliceResult returns leftGeometry and rightGeometry split by the infinite slice line.

No. Target and mask polygons with a non-zero radius are ignored by both Fragment and Slice operations. You must provide polygon geometry with zero radius for fragmentation to process it.

FragmentResult and SliceResult allocate native memory via the specified Unity.Collections allocator and must be disposed by calling Dispose() after use. Failing to dispose these results causes memory leaks.

Fragment and Slice accept a Unity.Collections.Allocator parameter restricted to persistent or temporary-style allocators as documented. The chosen allocator governs the lifetime of the returned native geometry results.
