Wall Climbing Side Scroller

I am working on a 3D Side Scroller game and I want to add a wall climbing mechanic. I want it so you go up to a special wall and press space which will start the climb. Should I set the movement to flying? How would I go about doing this?

Have you tried this? How to make a ladder with Blueprint? - UE4 AnswerHub

I have and this does not apply to a Side Scroller
