Thank you so much!!! That is exactly what I am looking: changeFactor. 2009/5/1 Jack Doyle <[email protected]>: > Here's a function that you can feed a start hex color, end hex color, and > however many steps you want, and it'll generate an Array with hex values for > that many steps: > > ------------------------------------------------------ > > function getHexSteps($start:uint, $end:uint, $steps:uint):Array { > var startVals:Object = {r:$start >> 16, g:($start >> 8) & 0xff, > b:$start & 0xff}; > var changeVals:Object = {r:($end >> 16) - startVals.r, g:(($end >> > 8) & 0xff) - startVals.g, b:($end & 0xff) - startVals.b}; > var hexSteps:Array = []; > var spacing:Number = 1 / ($steps - 1); > var changeFactor:Number; > for (var i:int = 0; i < $steps; i++) { > changeFactor = i * spacing; > hexSteps[i] = ((startVals.r + (changeFactor * changeVals.r)) > << 16 | (startVals.g + (changeFactor * changeVals.g)) << 8 | (startVals.b + > (changeFactor * changeVals.b))); > } > return hexSteps; > } > > ------------------------------------------------------ > > For example, getHexSteps(0xFF0000, 0x0000FF, 8) would return an Array that > has 8 steps total, going from red to blue: > [0xff0000, 0xda0024, 0xb60048, 0x91006d, 0x6d0091, 0x4800b6, 0x2400da, > 0x0000FF] > > So a simple use case that builds 30-pixel blocks across the stage, one for > each step would look like: > > var colors:Array = getHexSteps(0xFF0000, 0x0000FF, 8); > var s:Sprite; > for (var i:int = 0; i < colors.length; i++) { > s = new Sprite(); > s.graphics.beginFill(colors[i], 1); > s.graphics.drawRect(0, 0, 30, 30); > s.graphics.endFill(); > addChild(s); > s.x = i * s.width; > } > > Hope that helps. > > Jack > > > -----Original Message----- > From: natalia Vikhtinskaya [mailto:[email protected]] > Sent: Friday, May 01, 2009 7:38 AM > To: Flash Coders List > Subject: Re: [Flashcoders] Dynamically generate blend colors > > Thank you. Yes this class allows to create gradient.
