Ogre3dBody quaternion rotation by 180 degrees

Hi
Ogre suggest to handle special case when rotating 180 degrees to handle Divide by Zero error.
Following is an example code



void Dorotation()

{

	if ((1.0f + src.dotProduct(mDirection)) < 0.0001f)            // Work around 180 degree quaternion rotation quirk                         

 	{                                                                           

     		//mNode->yaw(Degree(180));                                                

		// how to complete this for the Ogre3dBody?

 	}                                                                           

	else                                                                        

	{                                                                           

		Quaternion quat = src.getRotationTo(mDirection);                        

		enemyBody->setGlobalOrientationQuat(quat);                                     

 	}

}

I want to know how to do this with Ogre3dBody. Because it does not have any yaw method.

OGRE3DBody::getSceneNode()->yaw(..);

Ok druha Thanx !!!
I completely forgot about the scene node
