Hey guys,

I am a little confused as to how tweening works in AS3… from what I gather the built in tween engine is terrible and should be avoided if possible. It seems to cause all kinds of problems which it really shouldn’t.

I am just wondering the the most simple approach would be to fade an item in and out, with the addition of easing? Lets say for example a button which when you roll over, fades out and when you roll out it fades back in again.

What methods do you guys use?
