Hi All,

I’m trying to find out if there is way through TweenLite to continuously check the Y position of my movieclip as it’s tweening?

I have my movie clip tweening from point A to point C and while it’s passing B, I want something to happen (right now I’m just running a trace). I’ve tried using the onUpdate function but it’s only tracing the original Y position everytime. Is onEnterFrame the only way to accomplish this task?
