How do I add footsteps sounds to my character? (In this specific scenario)

So… I decided for ‘footsteps’ I am just going to try working with the sounds in UE4 instead of wwise and I’m still not getting anywhere. I followed the instructions on the video you sent and also this one I have linked as well, and still no luck…I just need the ‘w’ key to make one footstep sound everytime it is pressed, is there another way of doing this?
