I have this in a function, and I want the code to remember my run_once_map_camera_span_calculate = 1 variable, is the only way to declare it as global?



EDIT: Are constants declared in functions forgotten as well?

Constants can't change so how can they be forgotton? Also, constants are all global anyway.

Yes, the only way is to declare it as global. You can avoid crowding the code with globals by making a UDT with all the values you need and then declaring a single global using that UDT.

You could also have your function return the value of run_once_map_camera_span_calculate and store it.

Go ahead. Walk into Mordor.

Thank you guys, it was for optimizing code and only running specific calculations once when needed. For now I will concentrate on progress in my programming of a map editor.
