AS3 use filters to implement highlighting (Glowfilter) __AS3

Effect chart

Before highlighting:

Highlight:

Import Flash.display.MovieClip;
Import flash.events.MouseEvent;
Import Flash.filters.GlowFilter;

var filter:array = [New Glowfilter (0xffffff,0.5,64,64,6,1,true)]
var rolemc:movieclip = this.role;
Rolemc.addeventlistener (mouseevent.mouse_move,onmouseover);
Rolemc.addeventlistener (mouseevent.mouse_out,onmouseout);


function OnMouseOver (e:mouseevent): void{
	rolemc.filters = filter;

function onmouseout (e:mouseevent): void{
	rolemc.filters = [];
}

Use the Glowfilter class to apply a glow effect to a display object. There are several options for the glow style, including inside or outside glow and knockout mode. When the distance and angle properties of the projection filter are set to 0 o'clock, the Glow filter is very similar to the projection filter. You can apply filters to any display object (that is, objects inherited from the Displayobject class), such as MovieClip, SimpleButton, TextField, and video objects, and BitmapData objects.
