Glow effect with GreenSock plugin in action script 3, download the latest files from the greensock site and copy the com folder from the zip package. I think the plugin is in com, otherwise make it in com folder.

glowFilter : Object – To apply a GlowFilter, pass an object with one or more of the following properties: alpha, blurX, blurY, color, strength, quality, inner, knockout, remove, addFilter, index

Syntax:

// TweenMax.to(target:Object, duration:Number, vars:Object)
TweenMax.to(mc, 1, {glowFilter:{color:0xFFFFFF, alpha:5, blurX:50, blurY:50}});

Step1:

Create a movie clip named “circle” (I used this name for the demo) or else.

Step2:

Set the document class as ‘com.Glow’

Setp3:

Create an action script file in the com folder and name it as Glow.as (which is same as in Document class)

Setp4:

Add Event Listener to the movieclip “circle” for the MOUSE_OVER and MOUSE_OUT events.

circle.addEventListener(MouseEvent.MOUSE_OVER, mc_mouseOver);
circle.addEventListener(MouseEvent.MOUSE_OUT, mc_mouseOut);

Function for the particular events.

function mc_mouseOver(evt:MouseEvent):void {
	TweenMax.to(circle, 1, {glowFilter:{color:0xFFFFFF, alpha:5, blurX:50, blurY:50}});
}
function mc_mouseOut(evt:MouseEvent):void {
	TweenMax.to(circle, 1, {glowFilter:{color:0xCCCCCC, alpha:0, blurX:10, blurY:10, remove:true}});
}

Setp5:

Run your fla by pressing Ctrl+Enter

Glow.as File

package com{
	import com.greensock.*;
	import com.greensock.easing.*;
	import flash.events.*;
	import flash.display.MovieClip;
	public class Glow extends MovieClip {
		function Glow():void {
			circle.addEventListener(MouseEvent.MOUSE_OVER, mc_mouseOver);
			circle.addEventListener(MouseEvent.MOUSE_OUT, mc_mouseOut);
		}
		function mc_mouseOver(evt:MouseEvent):void {
			TweenMax.to(circle, 1, {glowFilter:{color:0xFFFFFF, alpha:5, blurX:50, blurY:50}});
		}
		function mc_mouseOut(evt:MouseEvent):void {
			TweenMax.to(circle, 1, {glowFilter:{color:0xCCCCCC, alpha:0, blurX:10, blurY:10, remove:true}});
		}
	}
}
