Did Unity 4.2 break the current vuforia unity package?

Mines not working… anyone run into this. Did you find a solution?

It builds and runs, and shows the video, but no objects appear on the marker.

Wait no, the postprocess build player for vuforia does have Unity 4.2 support in it, and things explicitly put in for UnityAppController.mm

anyone know what I’ve done wrong?

Hi,

You are not alone. I am banging my head on this…

my problem is slightly different tho, I don’t get the “BackgroundCamera” to show the camera output. I simply get a black screen with very similar errors. I am trying to mess with IOS pubishing settings, with no luck…

Hopefully, someone will step in :slight_smile:

Bye,

Jean

Running Pro? I had issues with Android Free (black screen), had someone with Android Pro compile and was fine…

Is there any update on this? I am experiencing the same problems. The only material i found on this case was this: Getting Started | Vuforia Library. It is a little bit old and to be honest i am no iOS Developer, so I’ve got no idea what to do there.

Hi
is there some work or progress on it?
90% of the android devices i tested get black screen or crash on my vuforia app.
even Galexy 3 devices, which are good enough i guess.
getting crash or just black screen. no camera view.

On the ARCamera object make sure the data set load behaviour has the correct data set to active.

Thank you, Stephan! Works perfectly, now. I owe you a beer.

I had no issues with 4.2, but currently getting linker errors with 4.3:

Undefined symbols for architecture armv7:
  "__curOrientation", referenced from:
      -[UnityAppController application:didFinishLaunchingWithOptions:] in UnityAppController.o

Comparing the UnityAppController.mm file with one from a 4.2 build, that method is the same. The QCAR .a files got imported properly too, so I’m not sure what would cause this.

Edit:
Still no idea why this broke in the first place, but you can fix it by changing UnityAppController.mm (line 366 in the 4.3 version):

QCARUnityPlayer::getInstance().QCARSetOrientation(_curOrientation);

to:

QCARUnityPlayer::getInstance().QCARSetOrientation([orientation intValue]);

I automated this by changing the QCAR PostProcessBuildPlayer, line 298 to:

appcontroller.write('\tQCARUnityPlayer::getInstance().QCARSetOrientation([orientation intValue] /* for 4.2, use: _curOrientation */);\n');

There’s more correct workaround for this issue Getting Started | Vuforia Library

You can automate this by changing line 367 in Assets/Editor/PostProcessBuildPlayer

            if line.strip()[0:40] == 'static ScreenOrientation _curOrientation':

to

            if line.strip()[0:40] == 'static ScreenOrientation _curOrientation' or line.strip()[0:40] == 'static ScreenOrientation	_curOrientation':

They’ve changed space between ScreenOrientation and _curOrientation to tab in 4.3

I tried to use only the basic version of Unity and Vuforia Unity package kit. after I make some setups and when it runs onto the device, still got black rendering screen instead of a live video screen. Also, I turn on the the option from Web Cam Behaviour script that says “Don’t use for Play Mode” and I set the Synchronous Video to on before build and run in device, nothing happens and it is still black.
