Thank you! But I guess you are missing the point.
As soon as I trigger the Timer the execution is just fine, firing continuosly until I clear the timer. Just like you said, it’s triggering at the start and at the end. The problem is when. The start should be firing at the frame I placed my notify, but isn’t. Same for the end.
Moreover, I have the exact same setup that works like a charm in a third person template, traking the weapon animation in the exact frame range I need.
