# Astra.PhysicsFieldSample

Current field response at a world point. Wind drag is kg/s; linear/angular drag are exponential rates per second. Acceleration is m/s². Membership is evaluated at solver centers of mass, not collider surfaces.

**Namespace:** `Astra` · **Assembly:** `Astra.Scripting` · **Tipo:** Struct
