we have been successfully using btContinuousDynamicsWorld with our project so far. However, when we try to add btKinematicCharacterController to the world using addAction (or addCharacter), all simulation seems to stop (objects don't fall due to gravity anymore etc). If we change to btDiscreteDynamicsWorld, everything works normally (except now there's tunneling which we try to avoid by using btContinuousDynamicsWorld).
We have already wasted countless hours debugging this, so any help regarding the matter would be greatly appreciated
Thanks in advance,
John Arete
