assigning tween function in an array through a loop AS3

Hi, I have been trying to assign tween function in an array through a loop in as3.
I have 20 mc on stage, the instance names are obj1, obj2 and so on.
I want to assign a tween function to each of them, the function looks like this :

Actionscript Code:

function startTween(e:TweenEvent = null):void 
{
xTween = new Tween(obj1, "x", None.easeNone, obj1.x, Math.random()*20, 0.2, true);    

xTween.addEventListener(TweenEvent.MOTION_FINISH,startTween);
}

it worked, but only for obj1.

so I thought maybe I can put them in an array, var obj:Array = new Array(obj1, obj2.....);
and then I'll run a loop through it.

Actionscript Code:

for(var i:uint = 0; i < obj.length; i++)
{
function startTween(e:TweenEvent = null):void 
  {
    xTween = new Tween(obj[i], "x", None.easeNone, obj[i].x, Math.random()*20, 0.2, true);
                        
xTween.addEventListener(TweenEvent.MOTION_FINISH,startTween);
}
}

it doesn't work.I am not sure what went wrong.

it gave me this Error message: #1010: A term is undefined and has no properties.

Can anybody help? thanks

Try putting the for loop inside the function.

you mean like this?

Actionscript Code:

function startTween(e:TweenEvent = null):void 
{
for(var i:uint = 0; i < obj.length; i++)
{
xTween = new Tween(obj[i], "x", None.easeNone, obj[i].x, Math.random()*20, 0.2, true);
xTween.addEventListener(TweenEvent.MOTION_FINISH,startTween);
}
}

isn't that an infinite loop?

You forgot to import the packages and the function is in the wrong place.

PHP Code:

---

//Import the packages needed for tweening.
import fl.transitions.Tween;
import fl.transitions.TweenEvent;
import fl.transitions.easing.*;

//Array to hold all the object instances.
var obj:Array=new Array(obj1,obj2,obj3);

//Loops through all the movie clips in the array.
for (var i:uint = 0; i < obj.length; i++) {
    var xTween=new Tween(obj[i],"x",None.easeNone,obj[i].x,Math.random()*20,0.2,true);
}

//Listens to when the tween has finished 
xTween.addEventListener(TweenEvent.MOTION_FINISH,startTween);

//Displays message when tween is finished.
function startTween(event:TweenEvent):void {
    trace("finished tweening");
}
