CS4 Buttons - need help

Question

I have a question....I saw on a website once (I wish I could
remember which site it was), flash buttons that were creatively
animated.
The button would appear just as text, but when you hovered
over it, an image would rise from behind it, then, when you moused
off, the image would go back down.
It did this for each of the buttons and I cannot figure out
how to get that to work, especially since in CS4 with AS3 you
cannot use AS on a button.
It's also really difficult to add a motion preset to a
button....can anyone help?
I've looked for tutorials on how to add a motion
script/preset to a button however, I'm not finding anything at all.
Am I making this more complicated than it needs to be?
Should I put the button inside a movie clip and animate it
that way? I'm not sure if that will work since I am trying to make
an image appear behind the button when it's in it's OVER state.
Is there an easier way for me to do this?
Thanks.

Answer 1

Whatever you do will require a movieclip playing a role
somewhere along the line. For the scenario you described where the
image slides out and back in, it is more likely entirely a
movieclip.
What you want to do is create a movieclip that has mouse
event listeners that cause it to go to different frames for the
different states of the 'button'. So in frame 1 you would have the
'button' in its normal state, and a rollover could send it to frame
2 where you have an animation movieclip play. Then, when you roll
out you send it to another frame containing the reverse animation
which sends it back to frame 1 as its last action.
I thought I best add that the 'button' is the movieclip
itself, there is no real button involved.
