Question

I’m develop a game with starling-framework.my problem is how to detect all tween is complete when I add a set of elements into juggler.

current my plan is

while(some_condition){ //allocate a set of tween
     var tween=createTween(tweenCount++);
     tween.onComplete=function(){
         tweenCount--;
     }
}
function checkComplete(){
     if(tweenCount==0)
        doStuff();
     else
        setTimeout(checkComplete,1000);
}

and there is any better solution ? thanks for your time!

update

write a simple class to solve this ,seems like better

public class TweenMonitor 
{

    public function TweenMonitor() 
    {
        throw new Error('static class');
    }

    private static var refDict:Dictionary = new Dictionary();

    public static function monit(tweens:Vector.<Tween>,onAllFinish:Function,id:String='$default$'):void 
    {
        for (var i:int = 0; i < tweens.length; i++) 
        {
            var tween:Tween = tweens[i];
            if (tween == null)
                continue;
            if (refDict[id] == null) {
                refDict[id] = 1;
            }else
                refDict[id]++;
            tween.addEventListener(Event.REMOVE_FROM_JUGGLER,function (e:Event):void 
            {
                refDict[id]--;
                if (refDict[id] == 0)
                    onAllFinish && onAllFinish();
            });
        }
    }

}

You simply need the onComplete property of Tween Class (Starling Framework)

Here is an Example :

function addTween() { 

   var 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);   
   tween.onComplete = tween_complete;
   Starling.juggler.add(tween); 
}

function tween_complete() {

   // Handle Tween Complete Action Here   
}

EDIT

In case of multiple tweens, you probably could do better by attaching a timer class instead of settimeout:

while(some_condition){ //allocate a set of tween
     var tween=createTween(tweenCount++);
     tween.onComplete = function() { tweenCount--; }
}

var timer : Timer = new Timer(1000);
timer.addEventListener(TimerEvent.TIMER,update);
timer.start();    

function update(e) {

     if(tweenCount > 0) return;

     timer.stop();
     timer = null;

     doStuff();
}
