OT: Stupid c++ (Roguelike development)

[PvK]

C++ is trying to help you to help yourself to write nice code. Why do you want a class member function to have side effects on a global vector defined outside the class?

A nicer way to do it would be to have the constructor take a parameter which tells the object about the global vector (pass it a pointer or reference), store that pointer/reference and use that.
