Idle Miner Tycoon camera style

Hello,

I'm currently trying to implement a camera system in the style of idle miner Tycoon or others, it's simply a camera who reacts to the swipe of the finger going up and down with a little inertia. I'm not a specialist in mobile developement, especialy touches, I can't figure out how to do it properly, have you some hints ?

I managed to have a movement based on the swipe but it's kinf of messy...

Thanks,

TWB
