Notice that there are two things going on here... 1. Animate the opacity to semi-transparent 2. Animate the distance of the drop shadow Applying these two effects creates an illusion of depth within the application. It appears as though the object that you click on is lifted off of the plane of the application, and is dropped back onto the application when you release it. I hope this gives you a few ideas to help you make your own applications more interactive.
Tweener (caurina.transitions.Tweener) is a class used for creating tweenings and other transitions via actionscript code. The general idea is that dynamic animation and transitions (created by code) is easier to maintain and control, and more stable than timeline animation (since you can control it by time rather than by frames). Tweener is the spiritual successor to MC Tween. It follows Actionscript’s more strict OOP rules, and is released and maintained for both AS2 and AS3. Aimed both for designers and advanced developers, it still keeps the “one-line” design mentality used on MC Tween, but with a different, more fluid syntax (by way of an static class) that allows a wider control of how transitions are performed. Such characteristics weren’t possible on MC Tween due to the way the available parameters (and its order) were fixed by its syntax. Tweener downloads and documentation are hosted at Google Code.
