Thanks for the help guys.
Yeah, I’m not actually moving the player with this code, I’m simply playing an animation on top of the code that already exists to move the player forward so I don’t know if the axis mapping would work. I actually tried that and it didn’t have any useful effect because it just ended up playing my animation constantly. Hence why event tick doesn’t work in this situation because I don’t want the animation to play every frame, I just want to be able to let W know when I do toggle the Run and Walk with Shift.
Stunt Thumper, I think I’m too tired right now to make sense of what you did but it looks like it MIGHT work so I’m gonna try it tomorrow once I’m fresh again 
Essentially what you did is create a bool to check if I’m pressing W and then as long as W is pressed, if I press the shift key it will call the running state and when I release the shift key it will call the walking state. Is that right?
So essentially use the shift key to toggle the states rather than W… yeah I think that will work. I’ll let you know thank you
