I was surfing google code to see whats new . Found a new tweening class “caurina.transitions.Tweener”.
Tweener is a static class – that is, a class that allows you to run methods on it, or call its properties, but that never lets you create instances from it. This means that, with Tweener, you never create a new object – you simply tells Tweener to do something for you.
Tweener works on the idea that, instead of setting the value of a given property of a given object directly, as in myMC._x = 10, you can tell that property to create a transition to that value – by doing this transition or tweening, you can control your numeric data in a more fluid way. Doing slides, fades, and all kinds of animation is the result of this kind of manipulation: by making a property or variable go to one value or the other fluidly, not immediately.
