Away3D与Starling

Question

I have an Away3D 4.0 application with UI made in old flash display API, which can be only partly hardware accelerated.

On PC works fine, but the frame rate of UI on mobile devices is too low, hence I am porting it to Starling.

So I tried using both Away3D and Starling, but they don't work together (it compiles but there are run-time errors). What do I have to change? Specifically or generally for maybe another 2D library such as ND2D. Are there libraries that support this out of the box?

Edit: First I add an Away3D content and there are no errors. When initialising Starling, the error is in Starling.as (a library class) on line 249. I also tried this as someone suggested, but didn't make any difference (also information is 3 months old and libraries are being updated).

Edit 2: The error was caused by having a different enableDepthAndStencil value as is in Away3D, which is hardcoded in Sparling as false, because it doesn't really need it. Well, after "fixing" this there are no runtime errors: Away 3D content displays, but then I add Starling and the canvas becomes black. I guess I will have to dive into the Away3D source.

Answer 1

我把它按照此指导工作的意见和一算账（另外只有改变enableDepthAndStencil到true的Starling.as在updateViewPort()

Answer 2

You can view the source of the starling library on their github repository. Here is a link to the Starling.as file> https://github.com/PrimaryFeather/Starling-Framework/blob/master/starling/src/starling/core/Starling.as

the Starling method that is throwing an error is this:

        private function updateViewPort():void
        {
            if (mContext)
                mContext.configureBackBuffer(mViewPort.width, mViewPort.height, mAntiAliasing, false);

            mStage3D.x = mViewPort.x;
            mStage3D.y = mViewPort.y;
        }

From the look of that you should be able to remove this code for mobile, since your use will not be able to resize the viewport. To do this, download the library from the github repository, instead of using the swc onthe starling site. https://github.com/PrimaryFeather/Starling-Framework Then you can customize your starling build for compatibility with Away3D.
