[solved] ogreAL soundmanager?

I've been struggling with python-ogre's OgreAL wrapper for the last few hours. I can get one sound to play at a time but am experiencing intermittent "AttributeError: '_Exception_' object has no attribute 'py_err_class'" exceptions. I have little doubt that this is a question of my usage rather than a fault in the wrapper.

Does anyone have any code they'd be willing to share?

Thanks for bug reporting. Luckily it is pretty easy to fix and you don't have recompile the code.

Your ogre package should contain _ogre_exceptions_.py file. You will have to modify it. Please add next line to the file and let us know whether it worked for you or not:

_ogre_._Exception_.py_err_class = OgreException

Thanks

Thanks Roman. Yes, that fixed it. (Will you either commit the change or let Andy know?)

Andy already committed the changes:

The above exception problem aside, I'm still struggling to get python-OgreAL to function properly on our delivery machine. On my laptop it works fine. On the delivery platform, however, I hear a little blip of sound from the beginning of the ambient (background) track and then silence. I don't hear any fx.


self.soundmanager = OgreAL.SoundManager()

# ambient
self.ambient = self.soundmanager.createSoundStream("ambient", "ambient.ogg", True)
self.ambient.setGain(0.4)
self.ambient.setRelativeToListener(True)
self.ambient.play()

# fx (triggered on player action events)
self.sound = self.soundmanager.createSound('tool-off', 'tool-off.wav', False)
self.node.attachObject(self.sound)
self.sound.play()


Done -- in the SVN (untested)...

I am not sure whether this is an Python-Ogre bug or not. Can you write small tester using C++?

P.S. My guess is that bug is related to OgreAL and not to the bindings, but of course I could be wrong.

You might want to download openal (check out the OgreAL mailing list etc for details) and install it on the deployment machines to see if this makes a difference..

Also could you try a clean PythonOgre 1.0RC1 binary install (I think you are building from source?) to see if that works..

Cheers

Fixed. The problem went away by calling the sound's play method in a listener rather than prior to entering Ogre's rendering loop.
