In the Tween class in Flash MX 2004 the onMotionFinished is not
declared as an instance property. Therefore the sample script should
yield an compile error. To avoid this error (1) the Tween instance should
be typed as Object, or (2) the onMotionFinished event handler method
should be set with the bracket ([]) access instead of with the dot (.)
access.

(1) var myTween:Object = new Tween (arguments);
(2) myTween["onMotionFinished"] = function () {statement(s)}

After the execution of onMotionFinished, how can I determine which MovieClip had been tweened?

Is there a method available of the Tween object that retreives this information?

!lja,

try the following code:
myTween.onMotionFinished = function() {
myTween.yoyo();
trace(myTween.obj); // _level0.img1_mc
};

HTH,

If you set a stop action to the tween(in my case a rollOver), does this trigger the onMotionFinished event? Does it assume it is "finished"? Or does it have to reach the final destination assigned when you init the class? It is triggering the onMotionFinished when I assign a stop action to the Tween for some reason. Or is it supposed to work like this?

ben_marker : since you have a Tween.onMotionStopped event handler, i suppose you that it is triggered when you stop the anim, and Tween.onMotionFinished is called when the anim "reaches its end" (as written)

!lja : personnaly i've subclassed the Tween class to track the target object of the tween and also keep back a reference to an object that handle event.

import mx.transitions.Tween;

class ControlledTween extends Tween {
private var controller:Object;
private var target:Object;

public function ControlledTween(obj:Object,
prop:String,
func:Function,
begin:Number,
finish:Number,
duration:Number,
useSeconds:Boolean,
useController:Object) {
super(obj, prop, func, begin, finish, duration, useSeconds, useController);
controller = useController;
target = obj;
}
}

You can then access in the event handlers to the tweened object via the target member, and to an abitrary object via the controller member. (i use it when i try to follow MVC for the flash application, with code separation)

I want to play these transitions in sequence. This code doesn't work:
import mx.transitions.*;
import mx.transitions.easing.*;
var moonTween:Object = new Tween(mx.transitions.TransitionManager.start(mcMoon, {type:mx.transitions.Wipe, direction:0, duration:2, easing:mx.transitions.easing.Bounce.easeOut, param1:empty, param2:empty}));
var squareTween = new Tween(mx.transitions.TransitionManager.start(mcSquare, {type:mx.transitions.Blinds, direction:0, duration:2, easing:mx.transitions.easing.Bounce.easeOut, param1:empty, param2:empty}));
var oddTween = new Tween(mx.transitions.TransitionManager.start(mcOdd, {type:mx.transitions.Iris, direction:0, duration:1, easing:mx.transitions.easing.Bounce.easeOut, param1:empty, param2:empty}));

// alas this doesn't work
moonTween["onMotionFinished"] = function(){
squareTween();
}
Any idea how to make this work?
