         }
         if(Key.isDown(Key.LEFT)){
              Sprite1._x = Sprite1._x - 5;
         }
         if(Key.isDown(Key.UP)){
              Sprite1._y = Sprite1._y - 5;
         }
         if(Key.isDown(Key.DOWN)){
              Sprite1._y = Sprite1._y + 5;
         }
    }
    
    setInterval(moveobject,50);
