    4141    To create a Functor, the helper function createFunctor() is used. It returns an instance
    42     of orxonox::FunctorPtr which is simply a typedef of @ref orxonox::SharedPtr "SharedPtr<Functor>".
    43     This means you don't have to delete the Functor after using it, because it is managed
    44     by the SharedPtr.

     43    means you don't have to delete the Functor after using it, because it is managed
     44    by the std::shared_ptr.
