prevScene( ) Global Function
Flash 2
send a movie's playhead to frame 1 of the previous scene
prevScene()
Description
The prevScene( ) function moves the main playhead of a movie to frame 1 of the scene before the current scene and stops the main movie timeline. The current scene is the scene from which the prevScene( ) function is invoked. It must be invoked on a scene's main timeline in order to have an effect; that is, prevScene( ) has no effect inside a movie clip or onClipEvent( ) handler. If invoked from the first scene in a movie, prevScene( ) sends the playhead to frame 1 of that scene and halts movie playback there.
I recommend against using scenes when working with ActionScript-intensive movies. Unlike movie clips, scenes are not represented by objects and cannot be manipulated directly by most built-in functions. Normally, it's better to use labels and movie clips as pseudo-scenes in your timeline instead of using Flash's scene feature.
