I love the new ScrollRect with inertia - it feels very much like the swiping movement on iPhone. It just works - both with mouse in the editor and on device.
I would like to apply the same ability to the movement of the camera horizontally in my game.
Is there a way to do this right now?
Is there anything like this coming to uGUI?
There is nothing like that planned, no.
Damn! 
Ok - well I was originally handling the swiping with a rigidbody on the camera but I’m not happy with the inertia or the swiping control, which doesn’t quite keep up with the finger.
I will dig into the ScrollRect code and try to get it adapted. But then I would need an image component “background swiping layer” at the bottom of the hierarchy to receive the swiping events and then everything above it will work as usual I guess?
