水纹代码
一、设置舞台大小（256×256）。 二、导入图片到库,不要导入到舞台。
三、打开库设置图片链接。标识符为：surface ，将“为运行时导入”勾去掉，勾上“为actionscript 导出”和“在第一帧导出”
四、在第一帧插入动作代码(按F9，把下列代码粘贴进去即可）
var damper = new flash.display.BitmapData(128, 128, false, 128); var result = new flash.display.BitmapData(128, 128, false, 128); var result2 = new flash.display.BitmapData(256, 256, false, 128); var source = new flash.display.BitmapData(128, 128, false, 128); var buffer = new flash.display.BitmapData(128, 128, false, 128); var output = new flash.display.BitmapData(256, 256, true, 128); var surface = flash.display.BitmapData.loadBitmap(\"surface\"); var bounds = new flash.geom.Rectangle(0, 0, 128, 128); var origin = new flash.geom.Point(); var matrix = new flash.geom.Matrix(); var matrix2 = new flash.geom.Matrix(); matrix2.a = matrix2.d = 2;
var wave = new flash.filters.ConvolutionFilter(3, 3, [1, 1, 1, 1, 1, 1, 1, 1, 1], 9, 0);
var damp = new flash.geom.ColorTransform(0, 0, 9.960937E-001, 1, 0, 0, 2, 0); var water = new flash.filters.DisplacementMapFilter(result2, origin, 4, 4, 48, 48, \"ignore\");
attachBitmap(output, 0); var ms = getTimer(); var frame = 0;
var mouseDown = false; onMouseDown = function () {
mouseDown = true; };
onMouseUp = function () {
onEnterFrame(); mouseDown = false; };
onEnterFrame = function ()
{
if (mouseDown) {
var _loc2 = _xmouse / 2; var _loc1 = _ymouse / 2;
source.setPixel(_loc2 + 1, _loc1, 16777215); source.setPixel(_loc2 - 1, _loc1, 16777215); source.setPixel(_loc2, _loc1 + 1, 16777215); source.setPixel(_loc2, _loc1 - 1, 16777215); source.setPixel(_loc2, _loc1, 16777215); } // end if
result.applyFilter(source, bounds, origin, wave); result.draw(result, matrix, null, \"add\");
result.draw(buffer, matrix, null, \"difference\"); result.draw(result, matrix, damp);
result2.draw(result, matrix2, null, null, null, true); output.applyFilter(surface, new flash.geom.Rectangle(0, 0, 256, 256), origin, water);
buffer = source;
source = result.clone(); };
五、把帧频提高点（默认为12）
六、测试影片，呵呵，水波涟漪，真实再现，赶快试试吧！要点击一下哦！
