I’m using AS2, but this will help me with randomly generating hex values. Thank you so much!

Hi… Really thanks… Evan , i don’t know what were developers of AS3 thinking when not puting a HEX conversor in the flash libraries… but you solve it, almost i reinvent the wheel… But you solved this commnon issue… thanks..

Alright, I was pretty stupid with this. I forgot to add the r, g, b values to each other to get the total RGB value…

This is great, but I can’t make it work. I just needed a code which could transform separated R, G, and B values into one RGB value. But when I use your rgb2hex function and I give in 0xFF, 0xFF, 0xFF, then it fills my rectangle with red color instead of white.
Do you know why this happens? (I use _ to make the code more readable, they’re not in my AS file.)
colorBitmapData = new BitmapData(256, 256, false);

for (var i=0; i<256; i++) { ___for (var j=0; j<256; j++) {
______hex = rgb2Hex(0xFF, 0xFF, 0xFF);
______rect = new Rectangle(j, i, 1, 1);
______colorBitmapData.fillRect(rect, hex);
___};
};

private function rgb2Hex(r, g, b):Number {
___return (r<<16 || g<<8 || b);
};

I’m actually trying to create a gradient filled box which has 2 black corners, 1 white corner and 1 corner with a specified color value. But I don’t seem to manage the colors good enough even for a solid fill…

To my knowledge this is the only post that actually shows how to convert hex to RGB. Thank you very much. It works well for me.

Isaac, this is the bare minimum to transform a movieclip with an instance name of “mymc”
—

import flash.geom.ColorTransform;
import flash.geom.Transform;

var myTransform:Transform = new Transform(mymc);
var myColorTransform:ColorTransform = new ColorTransform();
myColorTransform.rgb = 0xFF0000;
myTransform.colorTransform = myColorTransform;

Is this really the bare minimum of what’s required to program a color change in flash? Basically… I have a movieclip in my library, and I have a command that will call that out and place it on stage, but for each time it’s loaded onto the stage, I want it to randomize its color. I’ve been trying to insert code to do this in the “function onLoad () { }” segment, but I don’t seem to understand how to get the colorTransform code to work on an already existing movie clip. I keep finding examples that involve creating objects from code…

It does totally make sense! I am trying to do the same as you, color the inner part of an image with borders. I suppose there is no easier way to do it than having 2 different movieclips, right?
