flash制作水波，根据鼠标点击产生效果

打开后用在画面上单击鼠标，或按住鼠标左键不放在画面上划过就会出现圈圈涟漪和波纹，非常美丽，跟真的水面一样，非常漂亮。 
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。 

var damper = new flash.display.BitmapData(128,128,false,128); 
var result = new flash.display.BitmapData(128,128); 
var result2 = new flash.display.BitmapData(256,256,128); 
var source = new flash.display.BitmapData(128,128); 
var buffer = new flash.display.BitmapData(128,128); 
var output = new flash.display.BitmapData(256,true,128); 
var surface = flash.display.BitmapData.loadBitmap("surface"); 
var bounds = new flash.geom.Rectangle(0,128); 
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],9,0); 
var damp = new flash.geom.ColorTransform(0,9.960937E-001,2,0); 
var water = new flash.filters.DisplacementMapFilter(result2,origin,4,48,"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 - 1,16777215); 
source.setPixel(_loc2,_loc1 + 1,_loc1 - 1,16777215); 
} // end if 
result.applyFilter(source,bounds,wave); 
result.draw(result,matrix,null,"add"); 
result.draw(buffer,"difference"); 
result.draw(result,damp); 
result2.draw(result,matrix2,true); 
output.applyFilter(surface,new flash.geom.Rectangle(0,256),water); 
buffer = source; 
source = result.clone(); 
}; 
五、测试看看。点击flash，会一出现圈圈涟漪，效果非常真实。 
還有就是這個.直接套用. 
var damper = new flash.display.BitmapData(128,128); 
var surface = flash.display.BitmapData.loadBitmap("bg1"); 
var bounds = new flash.geom.Rectangle(0,0); 
var ms = getTimer(); 
var frame = 0; 
var mouseDown = false; 
onMouseDown = function () 
{ 
    mouseDown = true; 
}; 
onMouseUp = function () 
{ 
    onEnterFrame(); 
    mouseDown = false; 
}; 
onEnterFrame = function () 
{ 
    if (mouseDown) 
    { 
        var _loc1 = _xmouse / 2; 
        var _loc2 = _ymouse / 2; 
        source.setPixel(_loc1 + 1,_loc2,16777215); 
        source.setPixel(_loc1 - 1,16777215); 
        source.setPixel(_loc1,_loc2 + 1,_loc2 - 1,16777215); 
    } // end if 
    result.applyFilter(source,wave); 
    result.draw(result,"add"); 
    result.draw(buffer,"difference"); 
    result.draw(result,damp); 
    result2.draw(result,true); 
    output.applyFilter(surface,water); 
    buffer = source; 
    source = result.clone(); 
};
