 There is one more method used in the script that is not in C++ or defined on the C++ code to bind a usertype, called ``brake``. Even if a method does not exist in C++, you can add methods to the *class table* in Lua:

 That script should run fine now, and you can observe and play around with the values. Even more stuff :doc:`you can do<../api/usertype>` is described elsewhere, like initializer functions (private constructors / destructors support), "static" functions callable with ``name.my_function( ... )``, and overloaded member functions. You can even bind global variables (even by reference with ``std::ref``) with ``sol::var``. There's a lot to try out!
