Ease applies to the entire classic/shape tween, not part of it.
100 means move more at the beginning (stop slowly), -100 means move more at the end (stop abruptly).
If you want the object to move slowly at both ends, break the tween into two tweens by inserting a keyframe in the middle, apply 100 ease at the latter half and -100 ease at the first half.
Thank you for your reply, unfortunately that isnt my problem. What I am seeing is that the ease will not apply to the motion when the value is set to 100. I did a test by changing the value to -100 to see if the ease would apply at all, which worked and the motion eased in. This isnt what I want however, I want the motion to ease out, but cannot get it to do so.
you try to use methods of easing in it.
you create a variable of type Tween.
then you create a function in which there are variables.
as an example I created in AS 3.0 a variable
inTween = new Tween (pic_mc, "y", Back.easeOut, 0,250,1, true);
and do not forget to import a class :
