In past versions of Director, the user would set keyframes and, with a keystroke, Director would do the in-betweens. If the velocity did not work correctly with the animation, the in-between frames would have to be deleted so that the key frames could be moved around. Hoping that the timing turned out correctly, the in-between frames could be put back in. Today, you can move the keyframes around and Director automatically adjusts the tweening of the objects without having to tell it to re-tween every time you adjust it. Behaviors is another great attribute of Director.
Behaviors are operations that define a simple procedure to an event.
These events could be rollovers, mouse clicks, and much more. In the past, the user had to learn Lingo to do these procedures, but now the Behaviors feature takes care of it for you. I recommend learning how to use Lingo and one great reason is the fact that it can push your presentations to new levels of interactivity. If all you are looking for is a basic presentation, using Attribute Scan can add a subtle but nice level of excitement to your work. In addition, Shockwave applets are also a great tool for Director developers.
