Is there a way to listen to the CONTEXT3D_CREATE event and the ERROR in away3d?

Or does away3d has a different way to test if the hardware is available?
See think link for what i want to test: http://www.bytearray.org/?p=3443

I’m doing this:

if (view3D.stage3DProxy.context3D.driverInfo.toLowerCase().indexOf("software") != -1)
   {
    var message:String = appConfig.messages.softwareModeAlert.toString();
    var alert:AlertBox = new AlertBox(message, appConfig.backgroundColour);
    alert.x = stage.stageWidth/2 - alert.width/2;
    alert.y = stage.stageHeight/2 - alert.height/2;
    stage.addChild(alert);
   } 

(found the same post!) but I think I’m having the same issue as yourself - sometimes Context3D is null. It would be great to be notified when it shows up.

Yes i also use that way but at the moment i check in an enter_frame loop if the Context3D != null and when it is i remove the loop and do the check.
But i see that as kind of a dirty hack so i rather have an event

Same here. There has to be a better way.

Ok, Stage3DProxy should be redispatching the CONTEXT3D_CREATE event as it has a onContext3DUpdate() method that is supposed to do exactly that. Maybe the listener is being added too late or something, but this looks like a bug so it’s going on the list.

There is a better way:

view.stage3DProxy.addEventListener(Stage3DEvent.CONTEXT3D_CREATED, onContext3DCreate);

That does the trick.
