flash as做的一个水波效果
主要使用了遮罩和beginGradientFill来实现,对机器要求比较高,机器不是很好的朋友慎狂点...

主要代码如下:
var?WaveArray:Array?=?new?Array();
var?rel_btn:MovieClip?=?this.loader.btn;
this.createEmptyMovieClip("gradient_mc",?3);
gradient_mc.cacheAsBitmap?=?true;
mc.cacheAsBitmap?=?true;
onMouseDown?=?function?()?{
new?Wave(WaveArray);
};
onEnterFrame?=?draw;
function?draw()?{
with?(gradient_mc)?{
??clear();
??spreadMethod?=?"pad";
??interpolati;
??fillType?=?"radial";
??colors?=?[0x00FFFF,?0xFFFFFF,?0x00FFFF];
??var?wal:Number?=?WaveArray.length;
??for?(var?i:Number?=?0;?i0???t?:?0,?WaveArray.R,?WaveArray.R+10];
???focalPointRatio?=?0;
???matrix?=?{matrixType:"box",?x:WaveArray.X-550,?y:WaveArray.Y-400,?w:550*2,?h:400*2,?r:180*Math.PI};
???beginGradientFill(fillType,?colors,?alphas,?ratios,?matrix,?spreadMethod,?interpolationMethod,?focalPointRatio);
???moveTo(0,?0);
???lineTo(0,?400);
???lineTo(550,?400);
???lineTo(550,?0);
???lineTo(0,?0);
???endFill();
??}
}
mc.setMask(gradient_mc);
}wave.as 中的代码如下：
