if (Input.GetMouseButtonUp(1))           //마우스 클릭 타입

{

    Ray ray;

    RaycastHit hit;

    ray = Cam.ScreenPointToRay(Input.mousePosition);

 

    if (Physics.Raycast(ray, out hit))

    {

        Vector3 offset;

        Vector3 scrSpace = Cam.WorldToScreenPoint(hit.transform.position);

        offset = hit.transform.position - Cam.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, scrSpace.z));

 

        Vector3 curScreenSpace = new Vector3(Input.mousePosition.x, Input.mousePosition.y, scrSpace.z);

        Vector3 curPosition = Cam.ScreenToWorldPoint(curScreenSpace); // +offset;

        GameObject Gameobject = hit.transform.gameObject;

    }

}
