The Code

We first create an empty movieclip and put the following code inside a keyframe:

MovieClip.prototype.checkPath=function(){
	this.onEnterFrame=function(){
		if(_root.movieHolder._url==undefined){			
			_parent._root = this._root;
		}else{
			_parent._root=_level0._root.movieHolder;
		}		
	}
}
this.checkPath();
The code is very simple. We give this movieclip a new class function called checkPath. To make sure that the path is checked all the time we add an onEnterFrame function. Then we ask whether a path is defined, which has _root.movieHolder._url in it. If the movie is alone or a level1 movie, this path does not exist and then the parent root is its own root. Otherwise the parent root is different and starts with the level of the parent movie (0) over the empty movieclip (movieHolder), which is now the root for the child movie. And this is all what it is about.

Important: When you use the pathcorrector component, all objects directly on the stage should not have _root in front. It is not necessary in any case to do that. Unfortunately, there is a habbit to do it, which has been also enforced by Macromedia and is in my opinion not correct, because objects on the stage are automatically located at the root. If you do that when you use the component, the component won´t work. Test it out by yourself with one of the objects, which I made invisible. Now to complete the lesson have a look at the rest of the code in child movie 1 and 2.
