Cannot load fl.transitions.Tween and other similar in project

I am using flex sdk 4.5 to develop my project. I need to use the generic Tweening packages in As3 but when I import these packages 

    import fl.transitions.Tween;
    import fl.transitions.TweenEvent;
    import fl.transitions.easing.*;

while compilation the sdk tell, it cannot find the upper packages. Any idea why, or how to import them?

Solution

  • Forget about native Tween class and switch to TweenLite / TweenMax. It's amazing and it will change the way you work. It's one of the best tweening library out there :)
