While creating a movie, you can perform many actions directly on Stage. Unlike other windows, the Stage has no title or scroll bars, and can be extended to the edges of the screen. The Score displays the state of all the elements in your movie over time. Choose Windows Score to open the Score. When you create a new sprite, Director places the sprite's image on the Stage and display information about when the sprite appears in the Score.
Sprites appear in the Score as bars extending across all the frames in which the sprite appears.
The numbers across the top of the Scores show the number of each frame. Frames represent a single step in the movie, like the frames in a traditional film. You set the playback speed of a movie by specifying the number of frames to be displayed per second. The playback head moves through the Score to show what frame is currently displayed on the Stage. The Playback Head moves to any frame you click in the Score.
