How to get a button to "pulsate"

Recommended Posts

Hey there,

I am trying to get a button to glow with a pulsating effect on ROLL_OVER.  I tried to link it back onComplete and have the 2 functions go back and forth, simply adjusting the alpha of the glow, but it throws an error.  Any ideas how to make this work?  Thanks

This is the most seamless way I could think of.


place a clip with instance name mc on the stage.


add this code:



import com.greensock.*;
import com.greensock.easing.*;
import flash.events.MouseEvent;

var pulse:TweenMax = TweenMax.to(mc, 1, {glowFilter:{color:0x91e600, alpha:1, blurX:30, blurY:30}, repeat:-1, yoyo:true, paused:true});

mc.addEventListener(MouseEvent.ROLL_OVER, over);

function over(e:MouseEvent):void{

mc.addEventListener(MouseEvent.ROLL_OUT, out);

function out(e:MouseEvent):void{
//tween the progress of the pulse tween back to 0
TweenLite.to(pulse, 0.8, {progress:0});

Tweening the progress of the pulse tween to 0 ensures that every time you ROLL_OUT the glow reverses smoothly. 


Give it a try, let us know if it works for you.

ReferenceError: Error #1069: Property progress not found on com.greensock.TweenMax and there is no default value.



I get this error on rolling out.  One my sample fla, I got it to work by making sure I was up to date with my green sock versions.  I saved my file in the same folder as my sample fla, and I am getting this error.  Any help is much appreciated as always.  Thanks!

Sorry, I thought this was resolved.


It sounds like you are using the old version of the animation platform v11 where TweenMax had 

a currentProgress property. 


2 options



1: Upgrade to v12 (many new features and enhancements) http://www.greensock.com/?download=GSAP-AS3



2: Stick with v11 and use currentProgress instead of progress in your tween


Let us know if this fixes it.
