Smooth Mobile Scroll

Hey there!

I'm trying to achieve that I can scroll a texture (inside a material) smoothly on mobile (by touch). Something like this: https://www.youtube.com/watch?v=IyeDbdAQCio

Right now I move the texture with the position.x of my finger, but when I release my finger, of course, nothing happens. What I want to achieve, as in the video, have a smooth scroll.

I have been looking through Google and the Unity forums but I haven't come across a solution and hoped if someone could steer me in the right direction!

Could you possibly use a ScrollRect using Unity's UI system? That offers smooth scrolling, and you can even set the deceleration rate.

If that does not work for you, you could try using UnityEngine.EventSystems and inheriting from IDragHandler and IEndDragHandler. Then, you make the texture follow you finger's x or y and average out the speed you finger is moving in OnDrag(), and make the texture begin decelerating in OnEndDrag().
