Getting Red from my color

Fri, 18 Dec 2009 04:58:00 -0500

I have a situation where I want to manipulate colors in flash. The idea is that the colors will cross fade nicely from one shade to another. While you can define colors like this: 0xef556ef that is stored as a unit data type. Looking at the above string, it's 8 char in length. The first two "0x" tell flash to treat this string as a hexadecimal value. the next two "ef" are the red value, the next two "55" are green and the last 2 "ef" are blue. Given the above value, I wanted to get the red shade of it, and only the red shade. This is what I came up with:



var myColor 		: uint = 0xef556ef

//convert the color to a string on a hex base and get the first 2 chars with "0x" at the front

var redValueString	:String = "0x" + myColor.toString( 16 ).substr(0,2);
				
trace( redValueString );

//convert the sting to the int value

var redValueInt		: int = int( redValueString );
				
trace( redValueInt.toString() );

This does give me the result, which is good, but I'm no flash pro, so is there a better (right?) way to do it? Feel free to tell me if there is!

Just got asked this by a work mate and after asking Mr Google and looking at the Array Documentation came up with this (Flex based) example, so thought I would share :-)
