Can't wrap my head around 3.0 "_root"

programming flash

Originally this file I have was built using AS 2.0. The boss wants it converted over to AS 3.0.For some reason i am having a difficult time getting my head around the fact there there is no longer a _root/_parent AND what to use in it’s place.

Does anyone have any helpful articles on this that I could read up on? I don’t mind reading up on it, I just can’t find a decent article that I know is correct! I did a search and it seems like every person has a different ways of calling back one or two scenes/MovieClips.

This is the code that I am working with. Basically I am in a movie clip (resortInfo) located on the main timeline. I want to call back to the main timeline (level0) and go into the movie navigation (has an instance name of “navigation”) to the frame label “images”…

Using AS 2.0 (code was on the button):


on (press) {
  this.gotoAndPlay("aruIimages");
}
on (press) {
  _parent["navigation"].gotoAndPlay("images");
}

AS 3.0 (taking code off the button):


aru_Btn.addEventListener(MouseEvent.CLICK, AruImages);

function AruImages(e:MouseEvent):void {
  this.gotoAndPlay("aruI");
  MovieClip(parent).["navigation"].gotoAndPlay("images");
}
