That’s irrelevant. You can just space these out in your animation for arms. In facts that is how I did it because I didn’t have 3rd person project I could do this in. Just test it out and see if it feels natural, comparing to your movement speed.
[Edit]
I’m not sure if that’s the case but I believe you should always clean and invalidate your timers before destroying the actor? You can promote the output of your timer to a variable, this will be your handle.
Put it on the graph before you destroy the actor and call “clear and invalidate…”
