ActionScript: loading variables from a text file into _root

Question

I'm basically a noob in ActionScript, and I've run into a problem. I want to load variables from a text file into the _root of my movie. Like, the text file contains &var=value&var2=value2& , and I want them to go straight into _root so that I'd be able to call them as _root.var and _root.var2. First, I tried using the obvious solution, loadVariables. I've done it through the following function:

function getState (save){
    //loadVariables("getstate.php?save="+save, "/");
    loadVariables("state.txt, "/");
}

I've tried loading it to "_root" instead of "/", but still nothing. The request gets sent, but the contents of the text file get lost in hyperspace on their way to my code.

So I tried using LoadVars instead of loadVariables. This function disappointed me because there wasn't the option of dumping the vars right into _root, but I decided to try it anyway. Here's how my function looks like with LoadVars:

function getState (save){
    varReceiver = new LoadVars();
    varReceiver.onLoad = function(){
        varsRecieved=true;
        _root.notloggedin = this.notloggedin;
        _root.nostate = this.nostate;
        _root.saveName=this.saveName;
        //and lots of other variables
        trace (_root.saveName);
    };
    varReceiver.load("state.txt");
    trace (_root.saveName);
}

The trace that is inside the onLoad function returns the correct value, but the one after it returns undefined. I've tried waiting for the onLoad to happen with this loop:

while (varsRecieved != true){
    trace ("not yet...");
}

Which sent Flash into an endless loop.

I'd really appreciate some help on this matter =)

Put the code that needs to be executed after the information has been loaded in a separate function and call that function at the end of the onLoad handler:

function getState (save){
    varReceiver = new LoadVars();
    varReceiver.onLoad = function(){
        _root.notloggedin = this.notloggedin;
        _root.nostate = this.nostate;
        _root.saveName=this.saveName;
        //and lots of other variables
        trace (_root.saveName);
        doRest();
    };
    varReceiver.load("state.txt");
}

function doRest()
{
    // ...
}

Note that getState() will return before the information has been loaded, so existing code may have to be moved to doRest().

Thanks, but this wouldn't help me much, as the code that needs to e executed after the information has been loaded is strewn all over my movie and can't possibly be fit into one function. — , Dec 08 '13 at 07:47
