title: Owl carousel 2 - drag direction
body: <p>I am trying to determine the drag direction of a slider, how do i achieve this? I need it since i am syncing 2 sliders, so i need to change the synced slider whenever the other one does. So far it works as long as you use the buttons to navigate, like this:</p>
  
  <pre><code>$('.owl-next').click(function() {
      sync2.trigger('next.owl.carousel');
  })
  $('.owl-prev').click(function() {
      sync2.trigger('prev.owl.carousel');
  })
  </code></pre>
  
  <p>And these events are on the sync1 slider, so whenever you go one or the other way, it will also move the sync2 the same way. I just need to do this when the user DRAGS the slider to change it. I can listen to the dragged event, but i have no way to determine if it was a left or right drag?</p>
  
  <p>In owl carousel 1 there was a dragDirection property, but that seems to be gone.</p>
