    Code:
    myLoadVars = new loadVars();
    myLoadVars.load("url");
    myLoadVars.onLoad = function( success ) {
         if ( success ) {
              // do something here
         } else {
              trace("load failed");
         }
    }
    By using this all my variables load into myLoadVars. I can't seem to access the variables through out my flash movie. Is there a way to load all the varibles in the main time line for easy access?

    if you are running that code on the maintimeline you access variables loaded into it like:

    myLoadVars.variable

    if you were on a timeline of an MC on the main timelien you use:

    _root.myLoadVars.variable

    or

    _parent.myLoadVars.variable

    however a new and interesting feature of MX is the _global command.

    if you use:

    _global.myLoadVars = new loadVars();
    myLoadVars.load("url");
    myLoadVars.onLoad = function( success ) {
    if ( success ) {
    // do something here
    } else {
    trace("load failed");
    }
    }

    you can then access the variables in your loadvars from anywhere using myLoadVars.variable

    cool ah

    hope this helps

    That's pretty cool.

    I'm loading a text file using your code just above.
    Is there a way to either transfer all the variables to the _root. instead of myLoadVars or can I do the same thing another way in order to get it to load into the _root?

    I know I can just use the loadMovie script and it will automatically load into _level0, but I need a way to check whether or not the txt file has been loaded using actionscript and this seems like a good solution.

    Any ideas?

    here you go!

    add the first function below once on the first frame of movie, now all of your loadVars objects will have a new function called "copyVars", pass it a movie target, and it will copy all the vars inside the loadVars object into that movie;


    Code:
    LoadVars.prototype.copyVars = function(target){
    	for(var i in this){
    		if(typeof(this[ i ]) != "function"){
    			target[ i ] = this[ i ];
    		}	
    	}
    }
    
    
    myLoadVars = new loadVars();
    myLoadVars.load("url");
    myLoadVars.onLoad = function( success ) {
         if ( success ) {
              // copy vars to root
    		  myLoadVars.copyVars(_root);
         } else {
              trace("load failed");
         }
    }
