It uses different transition functions * to give the animations various styles. * *

The primary use of this class is to do standard animations like movement, fading, * rotation, etc. But there are no limits on what to animate; as long as the property you want * to animate is numeric (int, uint, Number), the tween can handle it. For a list * of available Transition types, look at the "Transitions" class.

* *

Here is an example of a tween that moves an object to the right, rotates it, and * fades it out:

* * * tween:Tween = new Tween(object, 2.0, Transitions.EASE_IN_OUT); * tween.animate("x", object.x + 50); * tween.animate("rotation", deg2rad(45)); * tween.fadeTo(0); // equivalent to 'animate("alpha", 0)' * Starling.juggler.add(tween); * *

Note that the object is added to a juggler at the end of this sample. That's because a * tween will only be executed if its "advanceTime" method is executed regularly - the * juggler will do that for you, and will remove the tween when it is finished.

* * @see Juggler * @see Transitions */ export class Tween extends EventDispatcher implements IAnimatable { /** Creates a tween with a target, duration (in seconds) and a transition function. * @param target the object that you want to animate * @param time the duration of the Tween (in seconds) * @param transition can be either a String (e.g. one of the constants defined in the * Transitions class) or a function.
