Hi Rob.


Okay, I had to test this to see if it would work, and it does:


Your main movie clip has instance name of action clip. Drop it onto the

main timeline.

Create a clip with an instance name "forward clip". Give it a park frame

(empty, stopped), labeled "Park." Follow this with  a few frames each with

the action Tell Target ../action clip Go to next frame.  Label the first of

these frames "play." The last of these frames should have an extra action,

"Go To and Play label: Play," so that once this clip leaves the parked

frame it just keeps looping and telling the action clip to move forward a

frame at a time.

Create a similar clip but call it reverse and call its instance "reverse

clip."  It has an identical structure to the forward clip except replace

all "Go to next frame" actions with "go to previous frame."

Make a Play button and put it on the main timeline.  On rollover it tells

/reverse clip to park itself.  It tells /forward clip to go to and play

label:play. On rollout it tells /forward clip to park itself.

Make a Reverse button and put it on the main timeline.  On rollover it

tells /forward clip to park itself and tells /reverse clip to go to

label:play and play.  On rollout it tells /reverse clip to park itself.

If this doesn't work, I haven't described it accurately.  Email me and I'll

send you the Flash file (18k).


Thanks for the challenge.  It was fun.
