angle (GradientGlowFilter.angle property)

The angle value represents the angle of the theoretical light source falling on the object and determines the placement of the effect relative to the object. If distance is set to 0, the effect is not offset from the object, and therefore the angle property has no effect.

Example

The following example changes the angle property on an existing movie clip when a user clicks it.

import flash.filters.GradientGlowFilter;
var mc:MovieClip = createGradientGlowRectangle("GlowAngle");
mc.onRelease = function() {
    var filter:GradientGlowFilter = this.filters[0];
    filter.distance = 50;
    filter.angle = 90;
    this.filters = new Array(filter);
}

function createGradientGlowRectangle(name:String):MovieClip {
    var art:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth());
    var w:Number = 100;
    var h:Number = 100;
    art.beginFill(0x003366);
    art.lineTo(w, 0);
    art.lineTo(w, h);
    art.lineTo(0, h);
    art.lineTo(0, 0);
    art._x = 20;
    art._y = 20;

    var colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF];
    var alphas:Array = [0, 1, 1, 1];
    var ratios:Array = [0, 63, 126, 255];
    var filter:GradientGlowFilter = new GradientGlowFilter(0, 45, colors, alphas, ratios, 55, 55, 2.5, 2, "outer", false);
    var filterArray:Array = new Array();
    filterArray.push(filter);
    art.filters = filterArray;
    return art;
}
