Help with AS3 Scrolling News Ticker

[ctoomey]

I am trying to make a AS3 version of a scrolling news ticker although i seem to be having trouble. The code below doesn't seem to be working although its not throwing any errors. I think its not loading my xml nodes or something.

All i am trying to do is it to eventually load an rss feed and scroll a selected set of nodes. For now i just tried to get it to display an xml formated file since rss is xml formated. Ultimately for this example i just want it to display the title attribute of every item.

What am i doing wrong?

news_txt.x = 1024.0;
var count:int;
var textnode:String;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.TEXT;
loader.addEventListener(Event.COMPLETE, onComplete);

loader.load(new URLRequest("http://www.xlr8mobile.com/widgetdata/beowulf/audio.xml"));


function onComplete(event:Event):void
{
	try {
		var news:XML = new XML(event.target.data);
		news_txt.addEventListener(Event.ENTER_FRAME, onEnter);
		for each (var ticker:XML in news.newsitem.text()) {
			textnode += ticker + " ";
			news_txt.width += textnode.length;
			news_txt.text = textnode;
		}
	


	} catch (e:TypeError) {

		news_txt.x = 512.0;
		news_txt.text = "Could not create valid xml instance";
	}
}

function onEnter(event:Event):void
{
	//scrolls the text field
	news_txt.x--;
	if (news_txt.x == -1024.0) {
		news_txt.x = 1024.0;
	}
}

trace("text position " + news_txt.x)

Is their a simpler way to create this in AS3 then how i am doing it? If there is i would love to see an example of how to do it.

Have you done traces to see what is not working?

[ctoomey]

yes i have tried various simple traces to make sure functions and stuff are getting called and they seem to be. I think its an issue with my xml. The xml seems to be getting loaded though is it something with my nodes and not calling the right node maybe?

Any help would be appreciated.

trace the nodes.

Hi ctoomey. You can download the source files for AS3 XML News Ticker v3 from my Lab. I hope it helps you.

Hi there,

I made a similar ticker with a different approach using TextFormat(), substring() and slice().

Check a demo and download source files here

Hope that helps!
