BevelFilter (flash.filters.BevelFilter) 285

knockout (BevelFilter.knockout property)

public knockout : Boolean

Applies a knockout effect (true), which effectively makes the object's fill transparent and

reveals the background color of the document. The default value is

false (no knockout).

Availability: ActionScript 1.0; Flash Player 8

Example

The following example changes the

knockout property on the existing MovieClip instance

(

rect) when a user clicks it:

import flash.filters.BevelFilter;

var rect:MovieClip = createBevelRectangle("BevelKnockout");

rect.onRelease = function() {

var filter:BevelFilter = this.filters[0];

filter.knockout = true;

this.filters = new Array(filter);

}

function createBevelRectangle(name:String):MovieClip {

var w:Number = 100;

var h:Number = 100;

var bgColor:Number = 0x00CC00;

var rect:MovieClip = this.createEmptyMovieClip(name,

this.getNextHighestDepth());

rect.beginFill(bgColor);

rect.lineTo(w, 0);

rect.lineTo(w, h);

rect.lineTo(0, h);

rect.lineTo(0, 0);

rect._x = 20;

rect._y = 20;

var filter:BevelFilter = new BevelFilter(5, 45, 0xFFFF00, .8, 0x0000FF,

.8, 20, 20, 1, 3, "inner", false);

rect.filters = new Array(filter);

return rect;
