How to get loader url in progress handler

[Chetan Sachdev]

I am trying to get url in progresshandler. I tried typecasting event.target to LoaderItem, but it doesn't seem to work. event.target is of type LoaderMax. How can I get the currently loading item's url in progress handler ?

 

Please help..

I don't often use LoaderMax, but does event.data have anything useful in it (maybe it's the current LoaderItem? I couldn't tell...)? You'll need to wait for one of the LoaderMax pro's for a definitive answer sorry.

Hi Christian. Welcome to the GreenSock forums.

 

A LoaderMax can technically load many items simultaneously, so the when the progress event fires it isn't necessarily tied to 1 of the child loaders. The progress event only contains data associated with the object that fired that event, in this case your LoaderMax.

 

First, if you want to ensure that only 1 item is loading at a time, you can set the LoaderMax's maxConnections property to 1.

 

You have 2 options to figure out which child loader is currently loading.

 

1: assign onChildProgress or onChildOpen callbacks to the LoaderMax. Below is s brief example of using onChildProgress to gather the url of the currently loading item

 

 

import com.greensock.*;
import com.greensock.loading.*;
import com.greensock.events.LoaderEvent;


//create SWFLoaders
var swf1:SWFLoader = new SWFLoader("child1.swf",{container:this,y:0,autoPlay:false});
var swf2:SWFLoader = new SWFLoader("child2.swf",{container:this,y:100, autoPlay:false});


//create and populate LoaderMax
var lm:LoaderMax = new LoaderMax({onProgress:progressHandler, onChildProgress:childProgressHandler, onComplete:completeHandler, maxConnections:1});
lm.append(swf1)
lm.append(swf2)


lm.load();


function progressHandler(e:LoaderEvent):void {


}


function childProgressHandler(e:LoaderEvent):void {
trace("loading " + e.target.url);
}




function completeHandler(e:LoaderEvent):void {
trace("complete");
}

this will trace

 

 

loading child1.swf
loading child1.swf
loading child2.swf
loading child2.swf
complete

2: you can use the LoaderMax method getChildrenByStatus() to get an array of all the children based on a status. Read here: http://api.greensock.com/as/com/greensock/loading/LoaderMax.html#getChildrenByStatus()

Have you tried using the "currentTarget" of the event? Just like in Flash when you click on a particular DisplayObject and you've got a listener on the parent but the child was clicked, you can differentiate with target and currentTarget.
