Flash AS实现用鼠标来控制渐变填充

import flash.filters.GradientBevelFilter;  //引用flash的滤镜：GradientBevelFilter。
var shapeClip:MovieClip = this.createEmptyMovieClip("shape_mc", 1); //创建一个影片剪辑。

with (shapeClip) {                
    beginFill(0xFF0000, 100);
    moveTo(0, 0);
    lineTo(200, 0);
    lineTo(200, 200);
    lineTo(0, 200);
    lineTo(0, 0);
    endFill();
}　//定义影片剪辑shape_mc的大小。

shapeClip._x = (Stage.width - shapeClip._width) / 2;   
shapeClip._y = (Stage.height - shapeClip._height) / 2;//创建影片剪辑的界面

var colors:Array = new Array(0xFFFFFF, 0xCCCCCC, 0x000000); //设置颜色

var alphas:Array = new Array(1, 0, 1);   //设置alpha
var ratios:Array = new Array(0, 128, 255);//设置属性
var gradientBevel:GradientBevelFilter = new GradientBevelFilter(10, 45, colors, alphas, ratios, 4, 4, 5, 3); //设置滤镜、alpha、和大小

var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
    gradientBevel.strength++;
    shapeClip.filters = [gradientBevel];
};
mouseListener.onMouseMove = function() {
    gradientBevel.blurX = (_xmouse / Stage.width) * 255;
    gradientBevel.blurY = (_ymouse / Stage.height) * 255;
    shapeClip.filters = [gradientBevel];
};
Mouse.addListener(mouseListener);//定义鼠标函数
