Swipe Up and Down To Scale Object

So i am creating a game that if you swipe up the ball gets bigger and if you swipe down it gets smaller, i am not familiar with touch controls. i tried to find a way but i can’t, can somebody help me?

This is the only tutorial I could find that has anything to do with touch control… while I doubt this will help (I sure hope it does!) maybe it could act as a starting block for your project… I truely hope iam not misleading you, I am doing this in case maybe you actually found it useful and helpful for your project… iam an utter noob as well so… :smiley:

Have a great one!
