Example
The following example sets up two movie clips with gradient fills, and changes the blend
mode of the one in the foreground every second. In order to have the
show up with an effect, the gradient for the
and the blend mode is applied to the parent movie clip
"layer"
(
this.blendMode="layer"
this.createEmptyMovieClip("mc1", this.getNextHighestDepth());
this.createEmptyMovieClip("mc2", this.getNextHighestDepth());
this.blendMode="layer";
this.createTextField("blendLabel", this.getNextHighestDepth(), 50, 150,
100, 100)
fillClip(mc1, 0x00AA00, 0x22FFFF, 100, 100)
fillClip(mc2, 0xFF0000, 0x2211FF, 100, 50)
mc2._x = 33;
mc2._y = 33;
var blendModeIndex = 0;
setInterval(changeBlendMode, 1000);
function changeBlendMode()
{
mc2.blendMode = blendModeIndex % 14 + 1 ;
// values 1 - 14
blendLabel.text = (blendModeIndex% 14 + 1) + ": " + mc2.blendMode;
blendModeIndex++;
}
function fillClip(mc:MovieClip, color1:Number, color2:Number,
alpha1:Number, alpha2: Number)
{
matrix = {a:100, b:0, c:0, d:0, e:100, f:0, g:50, h:20, i:1};
mc.beginGradientFill("linear", [color1, color2], [alpha1, alpha2], [0,
0xFF], matrix);
mc.lineStyle(8,0x888888,100)
mc.moveTo(0, 0);
mc.lineTo(0, 100);
mc.lineTo(100, 100);
mc.lineTo(100, 0);
mc.lineTo(0, 0);
mc.endFill();
