  particle_registration.particle = particle
  particle_registration.particle_force_generator = force_generator
  @registrations << particle_registration
  puts "Registration count #{@registrations.count}"
end

#clear ⇒ Object

Clears all registrations from the registry. This will not delete the particles or the force generators themselves, just the records of their connection.

end

#remove(particle, force_generator) ⇒ Object

Removes the given registered pair from the registry. If the pair is not registered, this method will have no effect.

  end
end

#update_forces(duration) ⇒ Object
