Using a string as an integer and vice versa

It’s quite simple. Say you’ve got a menu whose textfields go field0, field1 etc. as instance names, and you want to reference it’s final character as the menu navigation id it’ll use to navigate to that location.

//code for the navigation buttons
addEventListener(TextEvent.LINK, navClick);

function navClick(event:TextEvent):void
{
  var field:String = event.target.name;
  var tempNum:Number = Number(field.charAt(field.length-1));
  tempNum += 3; // offset for preloader, menu etc. before sections. and the sections start at 1 not 0.
  gotoAndStop(tempNum);
}
