Hey there folks!:bu:

So, I have a project that I have to do in AS2 and I would really like to use the tween class to make my life a hell of a lot easier, but I’m not exactly sure how to use it. I was hoping that someone could point me to a detailed and relatively simple and straightforward tutorial or provide me one themselves.

I have some tool tips that show up when a movie clip is rolled over and I would like to animate them using AS2. The functionality would be: user rolls over an MC the invisible tool tip would tween to opaque and the y value would decrease by about 15px.

I’d really appreciate the help! Thanks!
