How to control "Horizontal" and "Vertical" axis using UI Buttons

Hi all! Recently I’ve got an idea to turn my cheap car game into a mobile game(I am not planning on relesing it just to learn new things and such). My idea is to use UI buttons that are Left, Right, Forward and Backward. Basicly AWSD but touch. I wanna use the buttons to controll the car. The car controller script is using “Horizontal” and “Vertical” axis for movement. Thanks to all of those that will help.

This is most important questiond asked 4 years ago and I’m willing to wait for the answer… Dude I’m looking for it tooo!
