Twitter + Papervision3D (using Tweetr)

Tuesday, March 31st, 2009 | examples

Thanks to Tweetr, using Twitter with Flash is extremely simple. This example shows the last tweet with the word “pv3d” in it. So feel free to post to twitter to see your tweet appear

package
{
	import com.swfjunkie.tweetr.Tweetr;
	import com.swfjunkie.tweetr.data.objects.SearchResultData;
	import com.swfjunkie.tweetr.events.TweetEvent;
 
	import flash.events.Event;
	import flash.filters.GlowFilter;
 
	import org.papervision3d.materials.special.Letter3DMaterial;
	import org.papervision3d.typography.Text3D;
	import org.papervision3d.typography.fonts.HelveticaBold;
	import org.papervision3d.view.BasicView;
 
	[SWF(width="900", height="480", backgroundColor="#000000", frameRate="31")]
	public class TweetrDemo extends BasicView
	{
		private var text3d:Text3D;
		private var yaw:Number = 0;
 
		public function TweetrDemo()
		{
			super(900, 480);
			opaqueBackground = 0x000000;
 
			var tweetr:Tweetr = new Tweetr();
			tweetr.search("pv3d");
//			tweetr.serviceHost = "http://pv3d.org/twitter/proxy";
 
			tweetr.addEventListener(TweetEvent.COMPLETE, tweetr_completeHandler);
			tweetr.addEventListener(TweetEvent.FAILED, tweetr_failedHandler);
		}
 
		private function tweetr_completeHandler(event:TweetEvent):void
		{
			var searchResultData:SearchResultData = event.responseArray[0] as SearchResultData;
 
			var letterMaterial:Letter3DMaterial = new Letter3DMaterial(0xcc0000);
			letterMaterial.doubleSided = true;
			text3d = new Text3D(searchResultData.text, new HelveticaBold(), letterMaterial);
 
			scene.addChild(text3d); 
 
			startRendering();
 
			viewport.filters = [new GlowFilter(0xffffff, 1, 3, 3, 10, 2)];
		}
 
		private function tweetr_failedHandler(event:TweetEvent):void
		{
			//fail
		}		
 
		override protected function onRenderTick(event:Event=null):void
		{
			text3d.rotationX++;
			camera.orbit(90, yaw++, true, text3d);
			super.onRenderTick(event);
		}
	}
}

You really have a unique way to pen down your thoughts. It is mind blowing and so informative that no one can put their eyes off from your views. This is great achievement and great creativeness..

hi their the comment about the error:

1172: Definition mx.events:IndexChangedEvent could not be found. in Tweetr.as line 18

is easily fixed just go into the com.swfjunkie.tweetr.Tweetr.as file and comment out line 18 and all works fine.

1172: Definition mx.events:IndexChangedEvent could not be found. in Tweetr.as line 18??

@Alexander - Yeah, that can sometimes happen if the twitter search for "pv3d" comes back with characters that aren't included in the font. I didn't put any error handling in there.

Alors comme tu voulais, je change la langue. ;-)

Malheureusement je recois cet alert du Flash Debug Player avec ma version 10:

TypeError: Error #1009: No se puede acceder a una propiedad o a un método de una referencia a un objeto nulo.
