Robotlegs 2 - Away3D

I'm having issues having the mediator for an Away3D view to create.

I have them mapped:;

But the mediator is not created even though I see the instance of the Away3DView on the stage.

For RL1 I saw a solution:

The reason stated being:
"by default Robotlegs automatically creates the Mediator when the View dispatches Event.ADDED_TO_STAGE. Object3Ds don’t dispatch that, so you have to create the Mediator yourself"

Is this still the case with RL2?

    Hi Jono,

    Robotlegs 2 works the same way as robotlegs 1 with regards to listening to added to stage events and creation of mediators.
    The new feature in rl2 is the ViewProcessorMapExtension:

    But, the issues encountered with away3d, starling, feather and the like remain: robotlegs can't handle 3DViews, either because, as you said, they don't dispatch added to stage events, or because the 3D stage doesn't have a display list ...

    My suggestion is to use this extension for robotlegs 2, which works with away3d and starling:

    Here are a few other extensions listed:

    Let me know if using sars solved your issues.

    Hi Ondina,

    Thanks for your reply.

    I looked at also and tried implementing it, but had no luck.

    I am actually using SARS already, a slightly modified version so I could use the latest Starling. I've not yet had to use any Away3D in it, but now when I try I'm not having much success.

    I re-created the SARS demo with these modifications to use the most recent components and put it here:

    Can you suggest the steps I would follow to add an Away3D element with a Mediator in this example?

    Many thanks,

    No problem, Jono.

    In the there is this:;

    Button3D is an away3d.containers.ObjectContainer3D and it implements IButton.

    Thus a ButtonMediator will be created for a Button3D when it is added as a child to a view3D.scene.

    The ButtonMediator has:

    public var view:IButton;

    Does that not work for you?

    Hi Ondina,

    Totally my bad - I dropped the ball on this one! When installing he SARS Bundle I forgot to pass the view3D (as previously I had no Away3D in this specific project) and then was attempting to add the Away3D instance an incorrect way also...

    After passing the "root" view3D and [Inject]ing the correct one all is good.

    Thanks for enlightening me : )
