As 创建发光滤镜范例代码

作者：袖梨 2022-06-28

创建一个新的 Flash 文档，并将其保存为 glowfilter.fla。
将下面的 ActionScript 代码添加到时间轴中的第 1 帧：

代码如下

复制代码

import flash.filters.GlowFilter;

this.createEmptyMovieClip("shapeClip", 10);
with (shapeClip) {
    beginFill(0xFF0000, 100);
    moveTo(0, 0);
    lineTo(100, 0);
    lineTo(100, 100);
    lineTo(0, 100);
    lineTo(0, 0);
    endFill();
}
shapeClip._x = 100;
shapeClip._y = 100;
shapeClip.onPress = function():Void {
    glow.strength++;
    shapeClip.filters = [glow];
};
var glow:GlowFilter = new GlowFilter(0xCC0000, 0.5, 10, 10, 2, 3);
var mouseListener:Object = new Object();
mouseListener.onMouseMove = function():Void {
    glow.blurX = (_xmouse / Stage.width) * 255;
    glow.blurY = (_ymouse / Stage.width) * 255;
    shapeClip.filters = [glow];
};
Mouse.addListener(mouseListener);
