How I can get Flashvars value from a package as class, not from the timeline?

I need to assign dynamically a path to a xml file through Flashvars. How I can make it work?

I was able to get Flashvar from html page into swf with actionscript code on timeline:

1. HTML – assigning Flashvars with swfObject:

Code:

---

<script type="text/javascript">
var flashvars = {};
flashvars.xmlfile = "xml/data.xml";
var params = {};
var attributes = {};
attributes.id = "IdScroller";

swfobject.embedSWF("scroller.swf", "flashDiv", "975px", "600px", "9,0,0,0", "expressInstall.swf", flashvars, params, attributes);
</script>

---

2. Actionscript code on timeline:

Actionscript Code:

var XMLpath:String;

//get flashvar value
if(root.loaderInfo.parameters["xmlfile"] != null){
    XMLpath = root.loaderInfo.parameters["xmlfile"];
}

var loader:URLLoader=new URLLoader();
loader.addEventListener(Event.COMPLETE,completeHandler);

// assign that value to URLRequest
var request:URLRequest = new URLRequest(XMLpath);
try 
{
    loader.load(request);
} 
catch(error:Error) 
{
    trace('Error on loading the image.');
}

It works great, but I really need to make it work within a package class. I have trouble to make it.
I am using EventDispatcher to load XML where I define the location path with this method. Below is the code fom this class:

Actionscript Code:

package com {
    
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.display.Sprite;

public static const CONFIG_LOADED:String = "configLoaded";
public static const DATA_XML_URL:String = "xml/data.xml";
private var configXMLLoader:XMLLoader;
private var xml:XML;
private static var _configManager:ConfigManager;

    
public class ConfigManager extends EventDispatcher {


public function load():void {
            
    // Create a new XMLLoader object    
    configXMLLoader = new XMLLoader(CONFIG_XML_URL);
            
    // Add an event listener to be dispatched when xml is parsed.
    configXMLLoader.addEventListener(XMLLoader.XML_LOADED, onConfigXMLLoaded);
            
    // Start loading the file
    configXMLLoader.load();
            
}

//This method is called when the configuration file is loaded.       
private function onConfigXMLLoaded(evt:Event):void {
            
// Read the setting values from the configuration file 
readConfig(configXMLLoader.getXML());
dispatchEvent(new Event(ConfigManager.CONFIG_LOADED));

}
                
//Returns the configuration manager.
        
public static function getInstance():ConfigManager {
            
    if (_configManager == null) {
    _configManager = new ConfigManager(new SingletonEnforcer());
    }
            
    return _configManager;
            
    }   
}
    
}

I cannot make it work at all. It will be great to find the proper way to do it. Please help! Thank you in advance.

you can only get the flashVars from the timeline or document root file........get them and then pass them to the class where you want to use them.

Any ideas on how I can pass it to the event dispatcher I mentionded above. Thank you again.

I also wanted to know how I can pass flashvars to a child swf. I am loading an external swf into main swf. The loaded swf has to be able to read flashvars. Any ideas???
Thanks.

you have to create a custom event dispacther which can take an array as a parameter......i use an external class witch extends event dispatcher and handles assiging the variable to the dispatch.....i can send you one if you like.

It will be great. I am using this technique forst time and have lots of milestones. Thank you again.

By the chance, I am wondering if you know how I can pass flashvars to a child swf. I am loading an external swf into main swf. The loaded swf has to be able to read flashvars. Any ideas???
Thanks.

here yo go get this installed in the same folder as the class you want to intiate the dispatch from and then i'll tell you how to call it.

here is the dispatch with two strings being sent as a test you can use variables which are holding data instead of strings also.

PHP Code:

---

dispatchEvent(new CustomEvent0("CustomEvent",false,false,"data0_tosend","data1_tosend")); 


---

Thank you for sending me as code. I am highly appreciate it.

I did install it in the class' directory. I have confiManager class which defines path to xml at this moment. This class public class ConfigManager extends EventDispatcher. Your class is in the same directory now. Please tell me what next I have to do and test it. Thanks.

put some traces inside the file i sent and dispatch the event to make sure it works.......you do know how to specify the package location from within the file i sent you right?

I am getting the error:

Quote:

---

super(type, bubbles, cancelable);

---

I added this:

Actionscript Code:

dispatchEvent(new CustomEvent0("CustomEvent",false,false,"data0_tosend","data1_tosend"));

to ConfigManager.as which I described above in the function below:

Actionscript Code:

private function onConfigXMLLoaded(evt:Event):void {
            
            // Read the setting values from the configuration file 
            readConfig(configXMLLoader.getXML());
            dispatchEvent(new CustomEvent0("CustomEvent",false,false,"data0_tosend","data1_tosend")); 
            dispatchEvent(new Event(ConfigManager.CONFIG_LOADED));

        }

Unfortunatelly, I am getting error, no trace statements. Did I do something wrong? I also cannot seen how it will read flashvars I am getting on the timeline. Thanks again.

we need to clarify this are you wanting to get the flashVars and then use them in the xml loader or do you want to get the variables and dispatch them to another class?

I need to pass XML path via FlashVars to the class below.
I need to assign Flashvars string which I can get in the timeline to "DATA_XML_URL" I have in this class.

Actionscript Code:

package com {
    
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.display.Sprite;

public static const CONFIG_LOADED:String = "configLoaded";
public static const DATA_XML_URL:String = "xml/data.xml";
private var configXMLLoader:XMLLoader;
private var xml:XML;
private static var _configManager:ConfigManager;

    
public class ConfigManager extends EventDispatcher {


public function load():void {
            
    // Create a new XMLLoader object    
    configXMLLoader = new XMLLoader(CONFIG_XML_URL);
            
    // Add an event listener to be dispatched when xml is parsed.
    configXMLLoader.addEventListener(XMLLoader.XML_LOADED, onConfigXMLLoaded);
            
    // Start loading the file
    configXMLLoader.load();
            
}

//This method is called when the configuration file is loaded.       
private function onConfigXMLLoaded(evt:Event):void {
            
// Read the setting values from the configuration file 
readConfig(configXMLLoader.getXML());
dispatchEvent(new Event(ConfigManager.CONFIG_LOADED));

}
                
//Returns the configuration manager.
        
public static function getInstance():ConfigManager {
            
    if (_configManager == null) {
    _configManager = new ConfigManager(new SingletonEnforcer());
    }
            
    return _configManager;
            
    }   
}
    
}

this is where I define static path to the data.xml. I need to modify it in a way I can pass it with FlashVars. Basically, I need to path a string of the actual data.xml file location.

here yo go get this installed in the same folder as the class you want to intiate the dispatch from and then i'll tell you how to call it.

oops sorry get the flashVar from the document root and pass it to the class through the

PHP Code:

---

var:Classname =new Classname(root.loaderInfo.parameters.flashVarName); 


---

Yes, I did it. The class you provided is placed at the same directory where dispatcher class is located. What next I should do? Thanks.

I placed it in the frame of the fla I use.

Actionscript Code:

var:Classname = new Classname(root.loaderInfo.parameters["xmlfile"]);

I am getting error:

Quote:

---

1084: Syntax error: expecting identifier before colon.

---

I am not sure what else I need to do. I need to assign Flashvars string which I can get in the timeline to "DATA_XML_URL" I have in this 'public class ConfigManager extends EventDispatcher'. I included this code above. Please let me know how it is possible to achieve. Thanks.

thats just an example it doesn't do anything do you know how to call a class from your document root? do you have a document root attached to your fla?

is the class you posted above the only class you have? if it is then you can get your flashVar directly out of it.

Not, I have other classes. This paricular 'public class ConfigManager extends EventDispatcher' has a reference to the statc path to data.xml which I need to modify to dynamic.

ok then where are you calling all your classes from? where are you calling

PHP Code:

---

var config:ConfigManager = new ConfigManager(); 


---

????

put root.loaderInfo.parameters["xmlfile"] in var config:ConfigManager = new ConfigManager(); as a parameter.

why do you need ["xmlfile"] ???? is ConfigManager being called more than one time per application?

No. I am calling all classes by assigning a path in Actionscript 3.0 Settings in Preference. I need to call it from html page because the xml files will loaded accroding to html page is loaded.

well you are programming incorrectly.........you should have a document class from where you call all your class from ....name this main.as and attach it by clickin on an empty grey part of the stage choose properties and then fill in document class to point at main.as make sure you extend main.as as movieClip

Perhaps, we are talking about different things. I just want to make sure I explained everything correctly. I just want to get to the bottom of it to make sure I have a good habit working on actionscript projects.
I created a project with one fla file, created 'src' folder to keep all classes I use, and other folders for images and xml. The way I link fla file to the classes is setting source path in ActionScript 3.0 Advanced Settings. To get there I had to do this:
In flash menu I go to Edit/Preferences, then I choose Actionscript tab and from that tab choose Language - Actionscript 3.0 Settings. In actionscript 3.0 Setting window I can define a source path to the class collection I use.
I used this approach few times and it worked always fine. I'd like to verify if this is really a wrong way to go. Please can you point me to the information about your approach you were telling about. I'd like to try it. Thank you again.

The technique isn't really documented via tutorial its more like a way of structuring a document from techniques in books such as Essential ActionScript 3.0 and techniques suggested to me on this forum by admins such as 5TonsOfFlax.......here is one of my main/document class

PHP Code:

---

package Main{
    import flash.display.*;
    import flash.net.*;
    import flash.events.NetStatusEvent;
    import flash.events.*;
    import NetConnections.NetConnections;
    import UserList.UserList;
    import SharedObjects.SharedObjects;
    
    import Chat.Chat;
    import Call.Call;
    import XMLang.Settings;
    
    import flash.net.*;
    import flash.xml.*;
    
    
    public class Client_Main extends Sprite {
         
        
        private var so:SharedObjects;
        
        public var chat:Chat;
        public var calls:Call;
        
        public var userName:*;

        private var clientID;
        public var uList:UserList;
        public var  width0:Number;
        public var  height0:Number;
        public function Client_Main() {
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;
            so = new SharedObjects(nc1);
            uList = new UserList(nc1,so.so2,so.so3);
            addChild(uList);
            calls = new Call(nc1);
            chat = new Chat(so.so1,nc1,userName,width0,height0);
            addChild(chat);

        }
        
        }
}

This is just a example document class but here is how it breaks down.
1.import all class packages
2. assign variable names for each class
3. call the class package with myclassvariablename = new myimportedclassPackagename();
4. if you have used addChild in the class pacakge then add child here also
addChlid(myclassvariablename);

Great, I will try this technique in my next project. Now, It will take some time for me to make within my existing project. I believe I still should be able to pass the Flashvar string to eventDispartcher class. As I understood correctly, I should call ConfigManager Class and pass the variable from main timeline. Can I call ConfigManager from the main timeline? I think I am lost here.

Don't try it on your next project you must use it on this one take the time to write it out won't take you as long as you think and your application will become much easier to handle.I didn't write the above post so you can ask a thousand un answerable questions related to your project.....I wrote it so you can organize and properly write your program.

I finally managed to create Main.as document class. Thank you for the lead.

I finally managed to create Main.as document class. Thank you for the lead. Now, I really want to get to the point I can pass flashvars into 'public class ConfigManager extends EventDispatcher'. I still cannot complete it. I need to pass flashvar into "DATA_XML_URL'. It is still not goiung well. When I call configManager class from document root I am getting the error:

Actionscript Code:

1136: Incorrect number of arguments.  Expected 1.

I imported and call this class:

Actionscript Code:

import src.ConfigManager;

Actionscript Code:

var config:ConfigManager = new ConfigManager();

Do you mind to help me to finish it? Thank you in advance.

Actionscript Code:

var cannot public static var DATA_XML_URL:String = "xml/data.xml";

Below is the class:

Actionscript Code:

import flash.events.Event;
    import flash.events.EventDispatcher;
    import flash.display.Sprite;
    import flash.display.LoaderInfo;

            }
            
            return _configManager;
            
        }
        
    }
    
}

pass the flash var from main to config manager .......you will have to chage xmlVar to the actual FlashVarName

PHP Code:

---

var config:ConfigManager = new ConfigManager(root.loaderInfo.parameters.xmlVar); 


---

intialize all varaibles here but don't assign the variable do that in the constructor like i've done with xmlVar1.

create class var

PHP Code:

---

 public class ConfigManager extends EventDispatcher {                
private var xmlVar1; 


---

assign passed flashVar to class var ("asssing value to all other variables here too") so it can be used outside the constructor

PHP Code:

---


 public function ConfigManager(passedFlashVar) {  xmlVar1 = xmlVar;   } 


---

now use xmlVar1 with your xml string

PHP Code:

---

DATA_XML_URL = xmlVar1; 


---

Thak you for the quick reply. I have problem in this step:

Actionscript Code:

assign passed flashVar to class var ("asssing value to all other variables here too") so it can be used outside the constructor
public function ConfigManager(passedFlashVar) {  xmlVar1 = xmlVar;   }

I have 'ConfrgManager' constructor I have this:

Actionscript Code:

public function ConfigManager(singletonEnforcer:SingletonEnforcer, ) {
        }

If I assign anything there, then I have erroe:

Quote:

---

1136: Incorrect number of arguments. Expected 2.
1120: Access of undefined property xmlVar.

---

How I define 'passedFlashVar' in here?

Actionscript Code:

public function ConfigManager(passedFlashVar) {  xmlVar1 = xmlVar;   }

Thnak you.

oh this is a mess.............what does(singletonEnforcer:SingletonEnforcer) do? where is the parameter getting its data?

PHP Code:

---

var config:ConfigManager = new ConfigManager(null,root.loaderInfo.parameters.xmlVar); 


---

PHP Code:

---

public function ConfigManager(singletonEnforcer:SingletonEnforcer,passedflashVar) {    xmlVar1 =passedFlashVar;    } 


---

PHP Code:

If you look at the ConfigManager class I included above it might explain why I have singelton. I changed the constructor and I am still getting the error:

Quote:

---

1136: Incorrect number of arguments. Expected 2.
1120: Access of undefined property xmlVar.
1049: Illegal assignment to a variable specified as constant.
and more

Line 188 is located in here:

            }
            
            return _configManager;
            
        }

Any ideas? I think we are really close. Thank you again.

PHP Code:

 _configManager = new ConfigManager(new SingletonEnforcer(),xmlVar1);

PHP Code:

Thank you so much for your responces. However, I have to leave for today. I will try to implement it and if I still will not b able to make I will get back here.
Once again, I really appreciate your help. THANK YOU!

Calmchess, I tried to not bother you with this issue but after spending a time on numerous attempts to make it work I am giving up. Obviously, I need to read more about AS 3.0, however, I'd like to find out what I shoud be doing to make it right now.

I have a Document class. I can get the Flashvars Value, but I fail to pass this string to the class needed.
I get Flashvars with this line of code:

Actionscript Code:

_flashVars = stage.loaderInfo.parameters.xmlfile:

I pass Flashvars to the class:

Actionscript Code:

var _config:ConfigManager = new ConfigManager(_flashVars);

Below is the main-document class:

Actionscript Code:

package src.vladc { 

    import flash.display.*;
    import flash.events.*; 
    import flash.display.DisplayObject;
    import flash.display.Loader;
    import flash.display.LoaderInfo;
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    import flash.events.Event;
    
    import flash.net.URLRequest;
    import flash.net.navigateToURL;
    import flash.display.Stage;

    import com.ConfigManager;
    
    public class Main extends MovieClip {

        private var _flashVars:String = "";
        private var _config:ConfigManager;
        
        public function Main():void {
            addEventListener(Event.ADDED_TO_STAGE, init);
        }
        
        public function init(e:Event):void {
            removeEventListener(Event.ADDED_TO_STAGE, init);
            _flashVars = stage.loaderInfo.parameters.xmlfile;
            var _config:ConfigManager = new ConfigManager(new SingletonEnforcer(), _flashVars);
        }
        
        public function get flashVars():String {
            return _flashVars;
            
        }
    }
}

I change const to variable and do not assign any value to it:

public static var DATA_XML_URL:String;

I add new variable:

private var xmlVar1;

I am passing Flashvars this way:

Actionscript Code:

public function ConfigManager(singletonEnforcer:SingletonEnforcer, _flashVars) { 

xmlVar = _flashVars; 

//I did this way too:

// DATA_XML_URL = _flashVars; 

}

I assign DATA_XML_URL in init function:

Actionscript Code:

DATA_XML_URL = xmlVar;

The ConfigManager class
Modified ConfigManager class below:

Actionscript Code:

import flash.events.Event;
    import flash.events.EventDispatcher;
    import flash.display.Sprite;
    import flash.display.LoaderInfo;
    import flash.display.MovieClip;
    import flash.display.Stage;

    
    public class ConfigManager extends EventDispatcher {
        // The name of the event to be fired when configuration is read
        public static const CONFIG_LOADED:String = "configLoaded";
        // Location of the data xml file
        // I need to assign FlashVars to DATA_XML_URL instead of the string that assigned now
        
        //public static var DATA_XML_URL:String = "xml/data.xml";
        public static var DATA_XML_URL:String;
        
        public static var PHOTO_DIR:String = "images/profile/"
        
        private var configXMLLoader:XMLLoader;
        // Xml data
        private var xml:XML;
        // A reference to the ConfigManager
        private static var _configManager:ConfigManager;
        
        private var xmlVar1; 

        
        public function ConfigManager(singletonEnforcer:SingletonEnforcer, _flashVars) {            
            xmlVar1 = _flashVars;
        }           
        public function load():void {
            init();
        }
        public function init():void {
            // Create a new XMLLoader object
            
            //Assign FlashVars to - DATA_XML_URL
            DATA_XML_URL = xmlVar1;
            
            configXMLLoader = new XMLLoader(CONFIG_XML_URL);
            // Add an event listener to be dispatched when xml is parsed.
            configXMLLoader.addEventListener(XMLLoader.XML_LOADED, onConfigXMLLoaded);
            // Start loading the file
            configXMLLoader.load();
        }
        private function readConfig(xml:XML):void {
            // Read configurations here
            PHOTO_DIR = xml.@photoDir;
        }
        //This method is called when the configuration file is loaded.       
        private function onConfigXMLLoaded(evt:Event):void {
            // Read the setting values from the configuration file 
            readConfig(configXMLLoader.getXML());
            dispatchEvent(new Event(ConfigManager.CONFIG_LOADED));
        }
        // Returns the configuration manager.
        public static function getInstance():ConfigManager {
            
            if (_configManager == null) {
                _configManager = new ConfigManager(new SingletonEnforcer());
            }
            return _configManager;
        }
        
    }
    
}

What I do wrong? Thank you again.

does xmvar1 trace a value inside config manager you have things correct i don't see where you use xmlvar1 as part of the path to call the xml file..........you are very close I'd trace my values each step of the way and find where it fails.

How can I trace it? I cannot publish it. I am getting errors - "1136: Incorrect number of arguments. Expected 2."

I believe it is something related to SingletonEnforcer. The class is below.

Actionscript Code:

package com {
    
    class SingletonEnforcer {}
    
}
