FlashVars Help - ActionScript 3.0

I am trying to load FLV files using FlashVars "file=rmpt://path_to_flv_file.flv" using ActionScript 3.0. I was following a tutorial http://reallyshiny.com/tutorials/flash.php but apparently this is for AS 2.0 and getting FlashVars informaion is not as simple as var=var anymore in AS 3.0.  anyways, question is:

Can someone help me dynamically load an FLV file into my FLV player with FlashVars ebmedded into the HTML of the page? What do I need to place in my FLA file to set the source of the FLV as my FlashVar variable?

FlashVars and querystring vars are still there, they have just been moved in AS3 (like many other things.)

In AS3 they can now be found in a generic object located at this.loaderInfo.parameters off the main timeline, or this.root.loaderInfo.parameters from elsewhere.

(It's best practice to typecast loaderinfo like: LoaderInfo(this.root.loaderInfo).parameters)

So if you have querystring vars like:


then the parameters object would look like:

parameters.var1 == "bob"
parameters.var2 == "jane"

This helps at a glance, but my question was "What do I need to place in my FLA file to set the source of the FLV as my FlashVar variable?" In other words, what is the exact AS code I would need to put into the first frame of the movie to assign the "file" var's contents to the player's source parameter.

Well, I figured it out myself. Was hoping for a quick help, but that's ok.

You pass variables through FlashVars to the SWF and retrieve them by simply typing:

root.loaderInfo.parameters.myFlashVar; Where "myFlashVar is the FlashVar passed. In my case, I wanted to dynamically load an FLV file from my php page and call the FLV based on user input. thus i placed:

player.source = root.loaderInfo.parameters.file;

on the first frame of my FVLPlayer movie. Where player is the instance name of the FLVPlayback Object and "file" is the FlashVar passed. I am dynamically setting the source of the FLV file. Works like a charm!
