Tweening a filter with AS

Question

So, I've figured out how to turn a glow on and off using AS.
Here is how I have done it:
quote:
button.onRollOver = function(){ fadeGlow = .7; }
button.onRollOut = function(){ fadeGlow = 0; }
import flash.filters.GlowFilter;
var glow:GlowFilter = new GlowFilter(0xffffff, fadeGlow, 7,
7, 1, 3);
button.filters = [glow];
But my question is, is there a way to tween this transition?
To tween an alpha, I would normally use something like:
quote:
fadeAlpha = (targetAlpha-_alpha) * .2;
_alpha += fadeAlpha;
(maybe I am even going about this wrong), but is there a
similar way to tween the property of the filter that I am trying to
target above?
Thanks!
(btw, I used quotes to insert my code because i cannot figure
out a way to insert code into my post without attaching it, which
just puts it at the end-is there a way to do this too?)

Answer 1

you must reassign the filters property on each change of your
blurX and blurY. ie, use the motion_change property of the
tweenevent class.
