Select the keyhole graphic
and convert it to a Movieclip symbol called keyhole.
Open the new symbol's actions pane and enter the following ActionScript
to make it draggable.
on (press){
this.startDrag(false);
}
on (release){
stopDrag();
}
When you test the movie now, you can move the keyhole around and
find things on the picture or try to guess what the picture is.
You could have the keyhole as a ball that bounces around the picture
and challenge your students to guess what the picture is.
The next part of the lesson shows you how the technique could be
adapted to produce a sideways scrolling background to a movie or
a panoramic view. |
