Hi all,

I’m trying to share the context with starling. The view works fine, but when I write those two lines:

m_view.stage3DProxy = stage3DProxy;
m_view.shareContext = true;

The view disappears.

Here is my init code:

public  function addView(ev:Event=null):void
  { 
   removeEventListener(Event.ADDED_TO_STAGE, addView);
   
   if (!isStage3DAndContextAvailable()){ return; }
   //m_camera.lens.far = 50000;
    
    stage3DManager = Stage3DManager.getInstance( stage);
   
   // Create a new Stage3D proxy to contain the separate views
   stage3DProxy = stage3DManager.getFreeStage3DProxy();
   stage3DProxy.addEventListener(Stage3DEvent.CONTEXT3D_CREATED, init);
   stage3DProxy.antiAlias = 3;
   stage3DProxy.color = 0x0000FF; 
   
   
  } 

public function init(event : Stage3DEvent):void
  {
    
   m_view = new View3D();
     
    setCamera(-4.98, -0.20, -38, 29);
  
     m_view.width =  640;
     m_view.height = 480;
    m_view.antiAlias = 3;
   m_view.backgroundColor= 0x333333;
   // Debug background
   //   graphics.beginFill(0xCCCCCC, 0.2);
   //   graphics.drawRect(0, 0, viewportWidth, viewportHeight);
   //   graphics.endFill();
   
   addChild(m_view);
}

You need to set the views stage3Dproxy

view.stage3DProxy = stage3DProxy;

//Also may need
view.shareContext = true;

Have a look at the tutorial on the site.

Sorry I forgot to add those two lines, but they are there.

The problem is when commenting those two lines that you mentioned, the view works, and I get the 3D contents rendered.

But when I leave them un-commented, the view disappears, and the 3D contents get lost.

And your enterframe listener is ?

stage3DProxy.addEventListener(Event.ENTER_FRAME, handleEnterFrame);

Otherwise you will need to call context present and clear in the render loop.
Again see tutorial

yes, its stage3DProxy.addEventListener(Event.ENTER_FRAME, handleEnterFrame);

I followed the tutorial and I have a sample prototype is working.

but when I deploy it in my large application, the above problems occur :(

I feel that there is a problem with that line:
stage3DManager = Stage3DManager.getInstance(m_content.stage);

In my prototype, everything works. but when I deploy it to a large game as I said, the view totally disappears. Would someone tell me what is the use of that function really ? how to add the stage parameter here ?
