Working with multiple movie clips
This article discusses a movie that was built in Macromedia Flash 5 using nested movie clips and buttons and ActionScript commands, including the startDrag action.
Dragging any of the first four buttons in the movie also causes another part of the movie to be dragged, as indicated by the labels next to each button. Dragging the fifth button moves only that button.
To view this demo, you need the latest version of the Macromedia Flash Player.

The dragging behaviors were created by attaching ActionScript instructions (called scripts) to the movie clips and the buttons. For each Drag action, a script sends a message from the controller (the movie clip where the script is located) to the target (the movie clip that moves when the controller is dragged).
To see how the movie was put together, download the source file, open it in Flash, and work with the file as you read this article. You can also simply read the article without downloading the file, and work with your own file later.
