Starling/Away3D interoperability is broken

[TerryCavanagh]

I think Starling and Away3D interoperability is currently broken. When I try making a simple demo project with a starling layer and an Away3D layer, it just renders a black screen. Here's an example:

radiosilence_hx.zip
(or on github here: TerryCavanagh/radio-silence-hx@d398652)

This example is basically just following this old Away3D tutorial written with AS3 - http://away3d.com/tutorials/Away3D_and_Starling_Interoperation

In addition, this unrelated issue #39 contains an example Away3D + Starling project, and it just renders a black screen for me too.

(Tested on Haxe 4.3.1, OpenFL 9.2.2, Lime 8.0.2, and Away3D and Starling up to date from github. Apologies if I'm just doing something dumb, as usual)

Just to follow up on this, we were able to get it working on our project essentially by fiddling around with events/ordering of things. Here is a commit that fixes it on our project: TerryCavanagh/radio-silence-hx@72f9f2f#diff-63879aafd34c9dbb5251d9c8266fc04c72c1259d876eae0cba9d84dfa8872684

So: there is a bug here, but it's one that can be worked around, so perhaps it's not that serious. Happy to close this?

A user linked this issue today, so I was reading through the commit which fixed the relationship between Away3D and Starling for a shared context.

Here are my notes for how to coordinate the two, I may have missed something

For Away3D:

var stage3DManager = away3d.core.managers.Stage3DManager.getInstance(stage);
var stage3DProxy = stage3DManager.getFreeStage3DProxy();

// Use Stage3DProxy for events, such as:
stage3DProxy.addEventListener(Stage3DEvent.CONTEXT3D_CREATED, onContextCreated);
stage3DProxy.addEventListener(Event.ENTER_FRAME, onEnterFrame);

For Starling:

var starling = new starling.core.Starling(MyStarlingGameClass, stage, stage3DProxy.viewPort, stage3DProxy.stage3D);
starling.shareContext = true;

// On enter frame
stage3DProxy.present();
MyStarlingGameClass.getInstance().update();
starling.nextFrame();
