Howdy, all!
I've got an audio engine I've built from scratch that I'm pairing with Irrlicht, but I need to get the forward vector of the camera in order to properly set the Listener Orientation. Does Irrlicht provide a convenience method for that?
Please let me know!

Re: Getting the forward vector of a FPS camera?
Forward is:
camera->getTarget() - camera->getAbsolutePosition ();
You might need to normalize depending on use. Also getPosition instead of getAbsolutePosition is good enough if you don't have parents for your camera.
If you also need up-vector, it's just camera->getUpVector()
camera->getTarget() - camera->getAbsolutePosition ();
