var mouseOverColor = Color.blue;
private var originalColor : Color;
function Start ()
{
originalColor = renderer.sharedMaterial.color;
}

   function OnMouseEnter ()
              {
    renderer.material.color = mouseOverColor;
              }

   function OnMouseExit () 
             {
    renderer.material.color = originalColor;
             }

   function OnMouseDown ()
            {
   var screenSpace = Camera.main.WorldToScreenPoint(transform.position);
   var offset = transform.position - Camera.main.ScreenToWorldPoint(Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z));

    while (Input.GetMouseButton(0))
                 {
	var curScreenSpace = Vector3(Input.mousePosition.x,Input.mousePosition.y, screenSpace.z);
	var curPosition = Camera.main.ScreenToWorldPoint(curScreenSpace) + offset;
	transform.position = curPosition;
	yield;
	//print("curScreenSpace"+curScreenSpace);
	//print("curPosition"+curPosition);
                }
         }

  function Update()
       {


   if(Input.GetMouseButton(0))
                     {
     	var	 ray : Ray = Camera.main.ScreenPointToRay(Input.mousePosition);
     	var hit :	RaycastHit ;
     		
            if(Physics.Raycast(ray, hit) )
                     {
              //print(hit.transform.gameObject.name); 
              Debug.DrawLine(Camera.main.transform.position,hit.transform.position,Color.red); 
              
                     }
                     
                     
                     }	

           }

Put this script into the object you want to drag and the object to be dragged should have a collider and make camera as Main
