From AS2 to AS3 â€“ Where did it go â€“ setRGB | [mck]

/ Published in: ActionScript 3

I really like the use of constants and the dollar sign ($) in this class. I have only used $ in jQuery to designate objects. Looks like one might use $ in AS3 classes to designate/differentiate passed-in variables from internal method/global vars.
