ActionScript in Flex Builder 3

[darkmist29]

--------------------------------------------------------------------------------

I've been working on an ActionScript project in Flex Builder 3 that I expected
to have the Tween classes. Since I built the ActionScript project in Flex 3, it
seems that I'm missing some classes that I would normally have if I was using
Adobe Flash CS3 or if I had built a Flex Project in Flex 3.

I was looking for fl.transitions.Tween or mx.effects.Tween - among others.

I'm looking at using the classes under fl.* because I can find them inside
Adobe Flash CS3. I'm trying to add a source folder, but only my intellisense
finds the classes - my builder doesn't seem to recognize anything. I get an
error saying fl.transitions.Tween cannot be found.

How do I get Tween functionallity? Am I headed in the right direction?

No luck getting the samples working?

I've looked over that sample.

Part of the problem is that I don't have access to mx.effects. I think this is
because that example is a Flex 3 Project and has a MXML file attributed to it.
I opened a Flex 3 project and was able to access mx.effects - but my project is
different in that it's an ActionScript project - meaning, I opened an
ActionScript project in Flex Builder 3. Apperantly the ActionScript projects
don't have access to mx.effects.Tween. And niether do they have access to
fl.transitions.Tween. It's strange - and I'm trying to find a way to access
them by connecting the build path to the Tween classes somehow.

My project preferences already have the fl.* folders in the build path. It
just still doesn't seem to work.
