* Use c++ methods as much as possible. * Use enum types for accessing NavMesh objects from array. * Use size_t for for loops when testing against size types. * Don't compute strlen twice of more on the same string. * Don't use unnecessary c string casts if there is a method with a std::string overload. * Don't create string objects from string pointers if we could use them directly. * Don't initialize RCON password twice on each change, and don't set if the new password equals the old.
