     public GUIStyle EnemyHealthbarBG;
     //public GUISkin SKIN = null;
 
     void OnGUI() {
     
     //    GUI.skin = SKIN;
         GUI.skin.verticalScrollbar.fixedWidth = Screen.width / 30;
         GUI.skin.verticalScrollbarThumb.fixedWidth = Screen.width / 30;
         scrollPosition = GUI.BeginScrollView(new Rect (Screen.width/6.5f,Screen.height/4,Screen.width/1.27f,Screen.height/1.5f), scrollPosition, new Rect (0,0,0,Screen.height/0.4f));
         GUI.Box (new Rect(0,0,Screen.width/1.4f,Screen.height/0.65f),"",EnemyHealthbarBG);
         //GUI.Box (new Rect(0,0,Screen.width/0.7f,Screen.height/0.65f),"",EnemyHealthbarBG);
         GUI.EndScrollView();
