Efflex is a set of designer effects for Adobe Flex created by Stephen Downs (aka "Tink"). Stephen presented Efflex at the recent Flash on the Beach conference and has a background in building applications for the Flash platform.
UrlKit supports Adobe Flex applications that need to expose URLs and window titles in the browser to represent their state. These URLs can be bookmarked, accessed via the Back button, etc. Such states typically represents some notion of location within the app, but in general can be mapped to any aspect of the application.
Specifically, UrlKit provides:
a Javascript library for deep linking in Flex 2 (in Flex 3, this is provided by the platform)
a library of declarative rule objects that describes the lexical elements of the application's URL and bidirectionally binds them to variables
a sample application
Joe Berkovitz developed UrlKit in collaboration with Todd Rein of Adobe. To find out why, read the Rationale.
The example: Click change state button, and look at your browser back button. NOTE: IE 6 user, please View example in a new window
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.
