Hi Lele,

John's reply has the information you need, however this can be a confusing

area until you get more familiar with it. It will get easier.


Using John's scheme, you will have a movie clip with two animation

sequences in the timeline: one forward, one reverse. Probably you'll want

each sequence to loop within itself, requiring a frame action at the end of

each sequence that returns playback to the first frame of that sequence.

You will place the movie clip on the main timeline, not in the button

timeline, and use instance actions of the button (rollover, rollout) to

TellTaget the movie clip to go to the start frame for the correct sequence.

Write us if you don't know how to use TellTarget yet.


Understand that rollout means "when the mouse cursor leaves the hot area,"

so the rollout action will continue indefinitely until the user rolls over

again or triggers some action to stop it (possibly a hidden button

surrounding a buffer zone outside the visible button).
