TGotoAndPlay(). Use this method to direct the play head to a certain frame and to a certain command inside the frame:
TGotoAndPlay(frame, label)
The file interactivesound.swf includes the frame beamscan. In this frame there are both stop and start labels. To send the play head to the beginning of the playback, do:
mySoundObj.TGotoAndPlay("/beamscan", "start");To stop the playback, send the playhead to the stop label:
mySoundObj.TGotoAndPlay("/beamscan", "stop");
The naming convention in Flash is similar to the unix directory structure. A top-level frame is written as a child of the parent timeline. That's why the frame name begins with a "/". The second parameter is a label name inside the frame: "start" or "stop". Notice that there is no command in Flash to start a playback or stop it. Instead, you direct the play head to a label that the author of the SWF file inserted.
