In a game I'm making right now, I found it necessary to convert hex to RGB for color changing, so I created the following function and share it with you guys.

function hexToRGB(hex:*):Object
{
	if (hex is Number) hex.toString(16).toLowerCase();
	else if (hex is String) hex.toLowerCase();
	else throw new TypeError("Expected Number or String);

	var red:Number = toNum(hex.charAt(0))*16+toNum(hex.charAt(1));
	var green:Number = toNum(hex.charAt(2))*16+toNum(hex.charAt(3));
	var blue:Number = toNum(hex.charAt(4))*16+toNum(hex.charAt(5));

	var RGB:Object = new Object;
	RGB.red = red;
	RGB.green = green;
	RGB.blue = blue;
	return RGB;
	function toNum(letter:String):Number
	{
		switch (letter)
		{
			case "a" :
				return 10;
			break;
			case "b" :
				return 11;
			break;
			case "c" :
				return 12;
			break;
			case "d" :
				return 13;
			break;
			case "e" :
				return 14;
			break;
			case "f" :
				return 15;
			break;
			default :
				return Number(letter);
			break;
		}
	}
}

Hope you all find it useful.

Ah, very nice. There needs to be a place to upload good AS3 code like this.

Anyway, hardcore code never gets enough appreciation in the forums, so here you are.


[6,11,4,10,2,10,-68,5,15,-68,16,4 ,1,-68,-2,1,15,16,-67].map(function(v){ return String.fromCharCode(v + 100) }).join(""); // updated for web 2.0!

Thanks, I was afraid this was going to fade away without so much as a single post.
