Hi,
ok, so you want actuall to have dragging, not swiping. Swiping is more like the IOS home screen paging solution, where as I think you may mean a simpler dragging system, not related to a real "Swiping" gesture implying maybe stopping as a very specific spot ( like the next page)
For this ( in both cases), I recommand using Input.Touches.
https://hutonggames.fogbugz.com/default.asp?W961 it has playmaker support, and so you can receive drag or swipe events and use the associated info action to know the delta drag, which is the amount by which you need to translate your camera.
Experiment with this and get back to me if you have still issues binding the camera with Input.touche system.
you can do this without any addon, but that's more advanced, and so I recommand going for the easy way here.
bye,
Jean
