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; i<wal; i++) {
alphas = [0, WaveArray.A, 0];
var t:Number = WaveArray.R-10;
ratios = [t>0 ? 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：
