9. Define private methods in the class that use the existing movie clip methods, startDrag() and
stopDrag():
class Drag extends MovieClip
{
function Drag()
{
onPress=doDrag;
onRelease=doDrop;
}
private function doDrag():Void
{
this.startDrag();
}
private function doDrop():Void
{
this.stopDrag()
}
}
10. Save the ActionScript file.
11. Test the Shape.fla document. You should be able to drag the movie clip.
Note: An example of the ActionScript file you just created, named Drag.as, is located in your finished
files folder. For the path, see “Set up your workspace” on page 113.
