Dear GEANT4 Users:
I am writing a simulation where I have 4 primary particles in each event. The starting position of the each subsequent particle depends on that of the previous one. So I can't set the correct primary vertex of the second particle until I know the last position in the track of the first particle. This cannot be done in the UserTracking because the argument of that function has the const qualifier.
Does anyone know how to do this?
