     if(Physics.Raycast(transform.position, fwd, hit, rayLength))
     {
         if(hit.collider.gameObject.tag == "Wood")
         {
             guiShow = true;

     }
     }
      function OnGUI()
     {
     if(guiShow == true)
     {
         GUI.Box(Rect(Screen.width / 2 - 150, Screen.height / 2 - 150, 100, 20), "PickUpObject!");
     }
     }
