can i use krpano.get(xml.url); for a plugin to read same xml?

mds · May 13, 2011 at 7:09 PM

Developing a plugin and I want it to read in the same URL that tour.swf is using. Is this possible using a variation of the AS below?

AS3 - not working

Code

var xmlUrlReq:URLRequest   = new URLRequest(krpano.call(xml.url));

If I use the same actionscript like this it works fine but I don't want to have it hard coded.

Code

var xmlUrlReq:URLRequest   = new URLRequest("tour.xml");

Much thanks!

you have to put a new var

var xmlLoader:URLLoader;

xmlLoader.load(xmlUrl);

you have to put a new var
var xmlLoader:URLLoader;

I've already got all the proper XML code in place (just didn't post it all)

for example this works fine:

Code

var xmlUrlReq:URLRequest   = new URLRequest("tour.xml");
var xmlUrlLoader:URLLoader = new URLLoader(xmlUrlReq);
xmlUrlLoader.addEventListener(Event.COMPLETE, xmlComplete);
xmlUrlLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlLoadFailed);

I just haven't been able to get the xml.url call from krpano working.

Try to reload krpano

krpano_load();

or the mane of your swf

tour_load();

Job.1 · May 13, 2011 at 8:38 PM

Code

function krpano_load():void
{
	var krpanoloader = new Loader();
	krpanoloader.contentLoaderInfo.addEventListener(Event.COMPLETE, krpano_load_complete); 
	krpanoloader.load(new URLRequest("tour.swf"));
}
krpano_load();

hmm, still nothing

I've done some testing and krpano.get(xml.url); is coming up undefined for me.

I'm loading my plugin with a hardcoded URL. And checking the "galleryPath" with a dummy text field, which is returning "undefined."

Am i needing to register an event or something else to get xml.url to work?

Code

loadXml("tour.xml");
xmltext.text = "path="+galleryPath;
var galleryPath = krpano.get(xml.url);

Ok ... never could get xml.url to work? Would love to figure out why.

Anyways ... I've come up with a workaround for those interested. I used a plugin attribute instead.

XML

Code

<plugin 
name="myPlugin"
url="myPlugin.swf"
xmlpath="gallery.xml"
/>

AS3

Code

var pluginPath = krpano.get("plugin[myPlugin].xmlpath");
var xmlUrlReq:URLRequest   = new URLRequest(galleryPath);

Not what I was hoping for but hey, it works!

Curious, why do you want to load the url?

I tested it in my javascript interface, and I get the url, so it works. But you can read the krpano xml with xml.content

Loading a xml thats already loaded by krpano, is a bit of wasted resources :) Alsoo xml.url get's the url of the panorama, so if you include xml, that will not be shown. Another downside to xml.url is, you get the path which is relative to krpano.swf, which isnt the path the plugin needs to load the xml.

So my advice, use xml.content

Btw this is the code which works for me:

Code

import krpano_as3_interface;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.Event;


var krpano        : krpano_as3_interface = null;


if (stage == null)
{
	// plugin startup
	addEventListener(Event.ADDED_TO_STAGE,     startplugin);
	addEventListener(Event.REMOVED_FROM_STAGE, stopplugin);
}


function startplugin(event:Event):void
{
	// now start
	krpano = krpano_as3_interface.getInstance();
	var xml_url:String = krpano.get('xml.url');	
	krpano.call("trace("+xml_url+")");
	krpano.call("trace(get(xml.content))");
	var xmlrequest:URLRequest = new URLRequest(xml_url);
	var loader:Loader = new Loader();
	loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
	
	loader.load(xmlrequest);
}
function stopplugin(event:Event):void
{
	// remove plugins events
	krpano = null;
} 
function loadComplete(evt:Event):void {


	var xml:XML = new XML(evt.target.data);


    krpano.call("trace("+xml+")");
}

Alsoo I see you want a gallery, and the gallery has a seperate xml file. You could choose to create your own xml tag and put it in krpano xml.

<krpano>
all your krpano stuff...

<gallery>
your gallery.xml
</gallery>

</krpano>

I think if you do krpano.get("gallery.content"); in flash, youll get the whole gallery contents (probally as string though) Look on the forum about arrays, I remember a few topics about looping the content of it.

Thanks for the tips Zephyr! Not sure if I actually need a separate xml file ... just playing with different options. I originally adapted an older dynamic xml thumbnail gallery of mine for krpano ... before I was more knowledgeable of krpano. That file had it's own xml reader coding and I never updated it.

can i use krpano.get(xml.url); for a plugin to read same xml?
