Hello everyone.
I have some problem.
My player is jumping on the world like a ball, sliding on the floor. I tried to set a pair of materials, but I failed. It's not change anything. Please help me.

	actorNode = mainNode->createChildSceneNode (name + "_actor", Vector3(0, -actorSize.y/2, 0));

    entity = engine->sceneMgr->createEntity(name, path);

    actorNode->attachObject(entity);

	cameraNode = actorNode->createChildSceneNode (name + "_camera", Vector3(0, 200, 200));

	engine->camera->lookAt(mainNode->getPosition());

    cameraNode->attachObject(engine->camera);

	velocity = strafe = 0;

	OgreNewt::CollisionPrimitives::Box* col = new OgreNewt::CollisionPrimitives::Box(engine->world->physWorld, actorSize, 0);

	body = new OgreNewt::Body(engine->world->physWorld, OgreNewt::CollisionPtr(col));

	body->attachNode(mainNode);

	double mass = actorSize.x*actorSize.y*actorSize.z*2.5;

	Vector3 inertia, offset;

	col->calculateInertialMatrix (inertia, offset);

	body->setMassMatrix(mass, inertia*mass);

	body->setPositionOrientation(position, Quaternion::IDENTITY);

	body->setCustomForceAndTorqueCallback<Actor>(&Actor::forceCallback,this);

	body->setMaterialGroupID(defaulted);

    OgreNewt::MaterialPair* pair2 = new OgreNewt::MaterialPair(engine->world->physWorld, defaulted, ground_material_id);

    pair2->setDefaultElasticity(0.5f);

    pair2->setDefaultFriction(1, 2);
