Does this Character code look right to you?

Does this seem like the proper way to be setting up a character?

Ogre::Entity *charEntity = mSceneMgr->createEntity( "Entity", "Donkey.mesh" );
Ogre::SceneNode *charNode = mSceneMgr->getRootSceneNode()->createChildSceneNode( "Entity" );
charNode->attachObject( charEntity );
charNode->setScale( Ogre::Vector3(1, 1, 1) );
charNode->showBoundingBox( true );

Ogre::AxisAlignedBox charAAB = charNode->getAttachedObject( "Entity" )->getBoundingBox();
Ogre::Vector3 min = ( charAAB.getMinimum() * charNode->getScale() );
Ogre::Vector3 max = ( charAAB.getMaximum() * charNode->getScale() );
Ogre::Vector3 center = ( charAAB.getCenter() * charNode->getScale() );
Ogre::Vector3 size( fabs( max.x - min.x), fabs( max.y - min.y), fabs( max.z - min.z ) );

NxOgre::CharacterParams characterParams;
characterParams.setToDefault();
characterParams.mDimensions.set( NxVec3( size.x, size.y, size.z ) );
characterParams.mType = NxOgre::CharacterParams::CT_Box;

mCharacter = mPhysScene->createCharacter(
"Player_Donkey",
NxOgre::Pose( Ogre::Vector3( 430, 230, 984 ), Ogre::Quaternion::IDENTITY ),
characterParams
);

It seems like a waste because I have to create an entity and a node to get the dimensions of my mesh to create the character, then use mCharacter->attachMesh( "donkey.mesh" ) to create the visible character, which is a 2nd entity to be created, along with mCharacter->createNode().

Does it also matter in which order you call createNode and attachMesh?

Why not create the node, then get the node and attach your entity. Instead of using attachMesh?

Touché. But then I seem to have trouble with the animations, it's saying the mesh doesn't contain any.

Ogre::Entity *charEntity = mSceneMgr->createEntity( "Donkey_Entity", "Donkey.mesh" );

// Character node
mCharacter->createNode();
mCharacter->getNode()->attachObject( charEntity );
mCharacter->getNode()->setScale( Ogre::Vector3(1, 1, 1) );

// Animation setup
Ogre::AnimationState *animation = ( ( Ogre::Entity* ) mCharacter->getNode()->getAttachedObject( "Donkey_Entity" ) )->getAnimationState("Action_Run");
animation->setEnabled( true );
animation->setLoop( true );

Edit: Fixed. =)
