TweenEffect is the superclass of all Tween-based animation effects, such as Resize, Move, etc.
MaskEffect is the superclass for animations that involves masks, such as Dissolve, Fade, Iris, etc. CompositeEffect is the base class for composite effects, such as Parallel and Sequence, which allow you to combine effects (playing together, or one at a time in order, respectively). Check out the Flex documentation for more information and examples. --- In [email protected], Nick Middleweek <n...@...> wrote: > > Hi, > > I'm reading up about Flex Effects...
