Hello, I got objects defined like that


//floor

  Ogre::Entity* floor_entity = mSceneMgr->createEntity("Floor", "cube.mesh");

	Ogre::SceneNode* floor_node = mSceneMgr->getRootSceneNode()->createChildSceneNode();

	floor_node->attachObject(floor_entity);

	floor_node->setScale(Ogre::Vector3(10,0.1,10));

	OgreNewt::CollisionPtr floor_col( new OgreNewt::CollisionPrimitives::TreeCollision( mWorld, floor_entity,true, 0));

	OgreNewt::Body* floorbody = new OgreNewt::Body( mWorld, floor_col );

    floorbody->attachNode(floor_node);

	floorbody->setPositionOrientation( Ogre::Vector3(0,-40,0), Ogre::Quaternion::IDENTITY );

	floor_entity->setCastShadows(false); 



	//box1

	Ogre::Vector3 size = Ogre::Vector3( 0.2, 0.2, 0.2);

	 Ogre::SceneNode* node = mSceneMgr->getRootSceneNode()->createChildSceneNode();

	 Ogre::Entity* ent = mSceneMgr->createEntity("box_body", "cube.mesh" );

     node->attachObject( ent );

     node->setScale( size );

     OgreNewt::CollisionPrimitives::Box *boxcol = new OgreNewt::CollisionPrimitives::Box(mWorld, size, 0);

    

     OgreNewt::Body* bod = new OgreNewt::Body( mWorld,  OgreNewt::CollisionPtr(boxcol) );

     bod->attachNode( node );

     bod->setPositionOrientation( Ogre::Vector3(-100,80,100), Ogre::Quaternion::IDENTITY );

	 Ogre::Real mass = 10.0;

     Ogre::Vector3 inertia, centerOfMass;

     boxcol->calculateInertialMatrix(inertia, centerOfMass);

     inertia*=mass;    

     bod->setMassMatrix( mass, inertia );

     bod->setCenterOfMass(centerOfMass);

	 bod->setStandardForceCallback();



	

	//box2

	 Ogre::SceneNode* node2 = mSceneMgr->getRootSceneNode()->createChildSceneNode();

	 Ogre::Entity* ent2 = mSceneMgr->createEntity("box_body2", "cube.mesh" );

     node2->attachObject( ent2 );

     node2->setScale( size );

     OgreNewt::CollisionPrimitives::Box *boxcol2 = new OgreNewt::CollisionPrimitives::Box(mWorld, size, 0);

	 //OgreNewt::Collision *box_col2 = OgreNewt::CollisionPtr(boxcol2);

     OgreNewt::Body* bod2 = new OgreNewt::Body( mWorld,  OgreNewt::CollisionPtr(boxcol2) );

     bod2->attachNode( node2 );

     bod2->setPositionOrientation( Ogre::Vector3(-100,20,100), Ogre::Quaternion::IDENTITY );

	 Ogre::Real mass2 = 10.0;

     Ogre::Vector3 inertia2, centerOfMass2;

     boxcol2->calculateInertialMatrix(inertia2, centerOfMass2);

     inertia2*=mass2;    

     bod2->setMassMatrix( mass2, inertia2 );

     bod2->setCenterOfMass(centerOfMass2);

	 bod2->setStandardForceCallback();
and my boxes just fall down and dont collide with each other. Any ideas?

Cheers
