RaycastHit2D.transform

Description

The Transform on the GameObject that the Collider2D is attached to.

When the RaycastHit2D result is returned from a physics query, the collider refers to the specific Collider2D that was detected however transform refers to the Transform on the GameObject that the RaycastHit2D.collider is attached to.

NOTE: transform is equivalent to using Collider2D.transform and is provided for convenience only. This field will be NULL if nothing was detected.

        RaycastHit2D hit = Physics2D.Raycast(transform.position, direction);

        // If something was hit then move the transform to the world origin.
        if (hit)
            hit.transform.position = Vector3.zero;
