Today I’m sharing with you a little utility that I find myself using a lot lately. This utility is a value convertor that you can use in those times when you need to make a volume slider or something similar where you’ll need to change a value and a value range.

package com.vamapaull.utils
	public class ValueConvertor
		public static function convertRange(originalStart:Number, 
			var originalRange:Number = originalEnd - originalStart;
			var newRange:Number = newEnd - newStart;
			var ratio:Number = newRange / originalRange;
			var newValue:Number = value * ratio;
			var finalValue:Number = newValue + newStart;
			return finalValue;
