Affecting Opacity and Size over time

Hi there,

As you may have read in my other thread about importing streams and visualising them (if not, it’s here: clicky), I’m currently working on a project which creates a visualisation using audio streams and is animated accordingly.

What I was wondering is how I go about animating a shape according to the stream data, such as the opacity or size over time. For example, I have a set of streams and I want to adjust the opacity and size of a shape according to the activity of the stream itself (i.e. if it is currently active or not).

I assume that this would mean animating the opacity and size using Actionscript, although I cannot find any threads or tutorials related to this.

Please could someone advise me further?

Cheers,
