Hello. I am trying to set up a static body like this. When i set the mass to zero nothing appears on my ogre window. When the mass is set to anything else it will appear. I don't understand. Is there a better way to do static bodies, thanks.



btTransform startTransform6;

     startTransform6.setIdentity();

    //Ogre::Vector3( Ogre::Vector3(mW[k].x,0,mW[k].z) + Ogre::Vector3(0 , buildsiteWall[k].height[0]+100 , 0) ))BtOgre::Convert::toBullet(Ogre::Vector3(mW[0].x,0,mW[0].z) + Ogre::Vector3(0 , buildsiteWall[0].height[0]+100 , 0)))

     startTransform6.setOrigin( btVector3(btVector3(mW[0].x,0,mW[0].z) + btVector3(0 , buildsiteWall[0].height[0] + 10 , 0) ));

     btScalar mass6(0);

    // colShape->setPosition(btTransform::getIdentity(), min, max);

     //rigidbody is dynamic if and only if mass is non zero, otherwise static

     // bool isDynamic1 = (mass6 != 0.f);

   

     btVector3 localInertia8(0,0,0);

    // if (isDynamic1)

     //colShape->calculateLocalInertia( mass6, localInertia8 );

             

        btScalar mass1( 0.0 );

  //  bool isDynamic1 = ( mass1 != 0.f );

 

   //   btVector3 localInertia8( 0,0,0 );

   // if ( isDynamic1 )

            colShape->calculateLocalInertia( mass1,localInertia8 );



    myMotionState8 = new MyMotionState(startTransform6,wall1[0]);

     btRigidBody::btRigidBodyConstructionInfo rbInfo6(mass1,myMotionState8,colShape,localInertia8);

     body6[0] = new btRigidBody(rbInfo6);

    body6[0]->setAngularFactor(.0f);

    body6[0]->setFriction(0.8f);



      body6[0]->setActivationState(DISABLE_DEACTIVATION);
