The `PhysicsContact` struct in the Sandbox namespace represents a contact point in a physics simulation. It provides detailed information about the contact, including the position, speed, and impulse of the contact point. This struct is immutable and is marked with the `IsReadOnly` attribute, ensuring that its fields cannot be modified after creation. It is also exposed for use in the s&box environment.

Instance Fields

Member Name	Summary
Point	The position of the contact point in world coordinates.
Speed	The speed of the contact point at the time of collision.
Normal	The normal vector at the contact point, indicating the direction of the surface.
NormalSpeed	The speed along the normal vector at the contact point.
Impulse	The impulse applied at the contact point during the collision.
