Follow the Leader
So what prompted this rather lengthy article on expressions and time delay? Well, I just so happened to be watching ESPN College Basketball a week or so ago, and became very interested in one of the animated backgrounds they were using. [an error occurred while processing this directive]In this animation, a central ring began moving back and forth across the screen, and as it did, adjacent rings began to follow the movement. This resulted in an undulating effect as the larger rings began to trail the original object.
With your knowledge of how this trailing expression works, you could very easily duplicate the above animation.
While I have only scratched the surface of expressions Ė we havenít even touched on multi-line scripts, you should now have a greater understanding of how expressions are written and what each element means. You can explore many of the other expression commands by clicking on the Expression Language Window arrow.
