button with sound and animation

[subside]

how do I create a button that when pressed plays a looped beat and a synced animation, and when pressed again stops both the animation and the loop.

Unfortunately, this is one thing that is not easy to accomplish in Flash.

probably the simplest thing to do is start the sound looping and the animation at the same time, but this does not guarantee sync. Eventually the two will drift appart.

a second option is to place the sound and animation on the root timeline set the sound to stream sync and duplicate the loop many times across the timeline, along with the animation. The advantage is that the sound and graphics will sync but you will have to rely upon streaming delivery for the sound, the sound and animation may stop playing intermitantly due to buffering if the user does not have enough bandwidth.

a 3rd option is to restart the animation and sound at the end of the sound using onSoundComplete. In this case the start of both animation and sound are always in sync but the ends may not be because Flash may adjust the frame rate occasionaly to accomodate the CPU load.

a 4th option is to repeatedly poll the position of the sound object as it plays and display graphics accordingly. This is counterintuitive to the way Flash handles animation and requires some committed ActionScript work on your part.
