Scrambles the text in a TextField with randomized characters (uppercase by default, but you can define lowercase or a set of custom characters), refreshing new randomized characters at regular intervals while gradually revealing your new text over the course of the tween (left to right). Visually it looks like a computer decoding a string of text. Great for rollovers.
You can simply pass a string of text directly as the scrambleText and it'll use the defaults for revealing it, or you can customize the settings by using a generic object with any of the following properties:
text : String - the text that should replace the existing text in the TextField (required).
chars : String - the characters that should be randomly swapped in to the scrambled portion the text. You can use "upperCase", "lowerCase", "upperAndLowerCase", or a custom string of characters, like "XO" or "TMOWACB", or "jompaWB!^", etc. (Default: "upperCase")
tweenLength : Boolean - if the length of the replacement text is different than the original text, the difference will be gradually tweened so that the length doesn't suddenly jump. For example, if the original text is 50 characters and the replacement text is 100 characters, during the tween the number of characters would gradually move from 50 to 100 instead of jumping immediately to 100. However, if you'd prefer to have it immediately jump, set tweenLength to false. (Default: true)
revealDelay : Number - if you'd like the reveal (unscrambling) of the new text to be delayed for a certain portion of the tween so that the scrambled text is entirely visible for a while, use revealDelay to define the time you'd like to elapse before the reveal begins. For example, if the tween's duration is 3 seconds but you'd like the scrambled text to remain entirely visible for first 1 second of the tween, you'd set revealDelay to 1. (Default: 0)
speed : Number - controls how frequently the scrambled characters are refreshed. The default is 1 but you could slow things down by using 0.2 for example (or any number). (Default: 1)
delimiter : String - by default, each character is replaced one-by-one, but if you'd prefer to have things revealed word-by-word, you could use a delimiter of " " (space). (Default: "")
