用as做滤镜效果,每种滤镜效果对应一个类别,这些类别将来会在Macromedia\Flash 8\语系\First Run\Classes\FP8\flash\filters 这个资料夹中找到说明档 一、渐变斜角——GradientBevelFilter类别 二、投影——DropShadowFilter类别 三、模煳——BlurFilter类别(这个最容易了,参数少) 四、光晕——GlowFilter类别 五、渐层光晕——GradientGlowFilter类别 六、斜角——BevelFilter类别 做法是用new关键字新建一个相应类的对象,暂时就叫myfilters吧,然后把这个对象增加进一个数组filters_array,最后把这个数组赋值给mc的fliters属性,大功告成。 我想其中关键应该就是建立对像时如何设定里面的参数吧,我想滤镜的面板大家都很熟悉的了,那么,我就把as增加滤镜的一些参数和它们的面板相对照,这样可能更容易理解。 下面逐个举例(都是辅助里的范例啦,里面的参数名字都是可以改的,不过我觉得就用那些名字就蛮好),范例里都有函数setUpFlatRectangle(也有叫createRectangle的),是用来做一个方形mc的。 function setUpFlatRectangle(w:Number, h:Number, bgColor:Number, name:String):MovieClip { var mc:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth()); mc.beginFill(bgColor); mc.lineTo(w, 0); mc.lineTo(w, h); mc.lineTo(0, h); mc.lineTo(0, 0); return mc; }直接把Script复制到主场景的第一影格就ok了,不要忘记上面的函数哦,要注意改函数名的 一、渐变斜角——GradientBevelFilter类别 Script: import flash.filters.GradientBevelFilter; import flash.filters.BitmapFilter; var art:MovieClip = setUpFlatRectangle(150, 150, 0xCCCCCC, "gradientBevelFilterExample"); //建立新的mc,实例名:art var distance:Number = 5; var angleInDegrees:Number = 225; // opposite 45 degrees var colors:Array = [0xFFFFFF, 0xCCCCCC, 0x000000]; var alphas:Array = [1, 0, 1]; var ratios:Array = [0, 128, 255]; var blurX:Number = 8; var blurY:Number = 8; var strength:Number = 2; var quality:Number = 3; var type:String = "inner"; var knockout:Boolean = true;//设定各个参数 var filter:GradientBevelFilter = new GradientBevelFilter(distance, angleInDegrees, colors, alphas, ratios, blurX, blurY, strength, quality, type, knockout);//建立斜角滤镜对像filter var filterArray:Array = new Array(); filterArray.push(filter); //把filter增加进数组filterArray,如果art上有多个滤镜效果,就直接增加进这个数组好了 art.filters = filterArray;//将art的filters属性设定为filterArray 下面是Script中的参数和面板中的参数对比 colors、alphas、ratios用来控制渐变颜色的,colors是色彩,alphas是百分比(这里面是0~1的小数),ratios是偏移量0~255(可以参考Color类)blurX、blurY是就对应面板里的模煳x、模煳y。strength是面板里的强度,是0~255的数;quality是品质,只有1、2、3分别对应低、中、高distance是距离,预设4.0;type是类型,用字串表示,范例中的」inner」是内侧,还有outer、fuller;knockout是个布尔值,表示是否挖空 二、投影——DropShadowFilter类别 import flash.filters.DropShadowFilter; var art:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample"); var distance:Number = 20; var angleInDegrees:Number = 45; var color:Number = 0x000000; var alpha:Number = 0.8; var blurX:Number = 16; var blurY:Number = 16; var strength:Number = 1; var quality:Number = 3; var inner:Boolean = false; var knockout:Boolean = false; var hideObject:Boolean = false; var filter:DropShadowFilter = new DropShadowFilter(distance, angleInDegrees, color, alpha, blurX, blurY, strength, quality, inner, knockout, hideObject); var filterArray:Array = new Array(); filterArray.push(filter); art.filters = filterArray;下面是Script中的参数和面板中的参数对比 Distance是距离; angleInDegrees是角度0~360 blurX、blurY是模煳x、模煳y strength是强度,Script里是0~5的数 quality是品质,只能是1、2、3,分别对应低、中、高 inner是内侧阴影 knockout是挖空 hideObject是隐藏对像 三、模煳——BlurFilter类别(这个最容易了,参数少嘛) import flash.filters.BlurFilter; var rect:MovieClip = createRectangle(100, 100, 0x003366, "BlurFilterExample"); var blurX:Number = 30; var blurY:Number = 30; var quality:Number = 3; var filter:BlurFilter = new BlurFilter(blurX, blurY, quality); var filterArray:Array = new Array(); filterArray.push(filter); rect.filters = filterArray;四、发光——GlowFilter类别 import flash.filters.GlowFilter; var rect:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample"); var color:Number = 0x33CCFF; var alpha:Number = .8; var blurX:Number = 35; var blurY:Number = 35; var strength:Number = 2; var quality:Number = 3; var inner:Boolean = false; var knockout:Boolean = false; var filter:GlowFilter = new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout); var filterArray:Array = new Array(); filterArray.push(filter); rect.filters = filterArray;五、渐变发光——GradientGlowFilter类别 import flash.filters.GradientGlowFilter; var art:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample"); var distance:Number = 0; var angleInDegrees:Number = 45; var colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF]; var alphas:Array = [0, 1, 1, 1, 1]; var ratios:Array = [0, 63, 126, 255]; var blurX:Number = 50; var blurY:Number = 50; var strength:Number = 2.5; var quality:Number = 3; var type:String = "outer"; var knockout:Boolean = false; var filter:GradientGlowFilter = new GradientGlowFilter(distance, angleInDegrees, colors, alphas, ratios, blurX, blurY, strength, quality, type, knockout); var filterArray:Array = new Array(); filterArray.push(filter); art.filters = filterArray; 这里的参数跟光晕的类别很像,需要说明的就是用来设定颜色的那几个数组里的4项依次是表示从外到内的颜色的 六、斜角——BevelFilter类别 import flash.filters.BevelFilter; var distance:Number = 5; var angleInDegrees:Number = 45; var highlightColor:Number = 0xFFFF00; var highlightAlpha:Number = 1; var shadowColor:Number = 0x0000FF; var shadowAlpha:Number = 1; var blurX:Number = 10; var blurY:Number = 10; var strength:Number = 2; var quality:Number = 3; var type:String = "inner"; var knockout:Boolean = false; var filter:BevelFilter = new BevelFilter(distance, angleInDegrees, highlightColor, highlightAlpha, shadowColor, shadowAlpha, blurX, blurY, strength, quality, type, knockout); var rect:MovieClip = createRectangle(100, 100, 0x00CC00, "bevelFilterExample"); rect.filters = new Array(filter);参数: highlightColor、highlightAlpha设定加亮颜色 shadowColor、shadowAlpha设定阴影颜色 |
