Create Tween with Actionscript 3.0

Ok, I just explained about this tutorial.

On frame 1, press F9 to open Action-Frame.
And typing following script :

- coordinate x

    import fl.transitions.Tween;
    import fl.transitions.easing.*;
    var myTween:Tween = new Tween(mc_box,”x”,Strong.easeOut,-300,250,1,true);

      3. Running program.

- coordinate y

     var myTween:Tween = new Tween(mc_box,”y”,Strong.easeOut,-300,250,1,true);

And create "Alpha".

     var myTween:Tween = new Tween(mc_box,”alpha”,Strong.easeOut,0,10,1,true);

~ good luck
