I don't know how to add the running function to the running button in my mobile game.

Hello, I’m new to forums and I’m using Unreal Engine 5.1. I’m working on a mobile game and I don’t know how to add a running function to the running button I shared a picture of. I would be very happy if you could help.

Thank you, but I want to assign a touch input to a button on the screen instead of a key on the keyboard. I’m new to the Unreal Engine, so I don’t know how to do it. However, I’ve tried something on my own.


Could you please point out the mistakes in this? Thank you in advance.
