"Trigger once" is meant to be paired with a condition, not used on it's own. Drag the code in event 9 to event 7 and it works.
You are amazing!. And yeah i been using a bunch of those trigger once's like that and pulling my hair out on some things haha. One other thing is, Is there any way to retrigger this dash during the dash itself? But not have the dash stop upon releasing the dash button. thanks again.
