CloseThe Rigidbody2D that the Collider2D detected by the physics query is attached to.
When the RaycastHit2D result is returned from a physics query, the collider refers to the specific Collider2D that was detected however rigidbody refers to the Rigidbody2D the Collider2D is attached to.
In the case where the Collider2D is not attached to a Rigidbody2D then rigidbody will be NULL.
NOTE: rigidbody is equivalent to using Collider2D.attachedRigidbody and is provided for convenience only.

using UnityEngine;
public class ExampleClass : MonoBehaviour { public Vector2 direction;
void Update() { // Cast a ray in the specified direction. RaycastHit2D hit = Physics2D.Raycast(transform.position, direction);
// If something was hit and it was attached to a rigidbody then move the rigidbody to the world origin. if (hit && hit.rigidbody) hit.rigidbody.position = Vector2.zero; } }
