Hi everybody. I have the next problem trying to create a MovieClip.
In short. It doesn´t show. I get NO errors nor warnings nor traces.

I added the png as an image to test it and in works.
I have my xml file loaded.
I have my imports.

This is part of the code:

.
/// The classes//
		[Embed(source='run.xml', mimeType='application/octet-stream')]
		private static const chipXML:Class;
 
		[Embed(source='run.png')]
		private static const chipTexture:Class;
////////
 
var _bmp:Bitmap = new chipTexture();
var _txture:Texture = Texture.fromBitmap(_bmp);
var _xml:XML = XML(new chipXML());
 
var atlas:TextureAtlas = new TextureAtlas(_txture,_xml);
var frames:Vector.<Texture> = atlas.getTextures('run');
var c:MovieClip = new MovieClip(frames);
 
addChild(c);
Starling.juggler.add(c);

------

The result is no image nor animation on screen
No errors traced

I´m a newbee on starling and i´m sorry f i´m doing something stupid.
Thanks everyone

hi,
you should try first with :
var frames:Vector.<Texture> = atlas.getTextures();
// maybe the xml doesn't contain frame(s) with a name starting by "run"

Hi neokeats.
Thanks for your advice, but i just tried it and it didn't work.
Also here´s part of the xml. It is longer but essentially the same.

<?xml version="1.0" encoding="UTF-8"?>
<TextureAtlas imagePath="run.png" width="512" height="512">
<SubTexture name="run0001" x="2" y="2" w="94" h="156" oX="230" oY="128" oW="550" oH="400"/>
<SubTexture name="run0002" x="98" y="2" w="94" h="150" oX="230" oY="134" oW="550" oH="400"/>
<SubTexture name="run0003" x="194" y="2" w="98" h="148" oX="229" oY="136" oW="550" oH="400"/>
</TextureAtlas>

I have no idea whats going on.

Thanks for your help.

Just in case a add here what happens first. Where i initialize the starling instance

		public function test()
		{
			this.addEventListener(Event.ADDED_TO_STAGE, start);
		}
 
		protected function start(event:Event):void
		{
			var _stats:Stats = new Stats();
			addChild(_stats);
 
			st = new Starling(mymain,stage);
			st.enableErrorChecking=false;
			st.start();
		};

Use one of the starling demos as a startup to see what is wrong...

I found it

TexturePacker generates an xml like the one i showed above.

In fact, the lines generated looks like this:

<sprite n="run0001" x="2" y="2" w="94" h="156" oX="230" oY="128" oW="550" oH="400"/>

In the sample i copied above a had already modified the lines, replacing "sprite" for "SubTexture" and "n" for "name"

But the problem was solved when a replaced "w" for "width" and "h" for "height"

I think thats why a have no error nor images. I suposed that starling does not interpret the "w" and "h" as width and height, but, instead an error, it might asume a 0 (zero) as width and height. So it shows "nothing". It works, but the images have zero as size. So a have no errors.

I don´t know why TexturePacker does this with the xml.
I don´t see that those xml labels could be personalized at the moment of export.

You are using "Sparrow" as your data format?

I was NOT. And that was my mistake.
Thank You very much Jeff.
