How do I make "slide" controls

I'm very new at this and I'm making a mini game where I would like the controls to be...slide on the screen to move my player left or right. A very good exemple of what I want would be the game Tiny Goalie (check it out on google play or app store...I'm too new to post links yet).

I probably have to use the Touch option...but how ?

you could start with playing around with the Slide Bar controller and make your own when you get used to it.

I assume if you have slide controls you are adjusting speed or something sort of range mechanic i.e. values from 0-100

I didn't had the slide bar option so I just downloaded the new version.

Yes, basically I want my player to go left when I slide left and right when I slide right.

So I'll play around with this new feature and see what happens !

Thank you.
