Also I must be mis-understanding something, because I have a Move()

another file and not exactly sure how to go about that, do they have
to be in a class? Because I just put the functions into another .cpp
file and they can't reference the global dungeon array.

Always declare classes and structs and such in your .h/.hpp files.
The .cpp files should only contain the actual code, ie, the
implementation of what you declared. If you need a global variable/
object/whatever, do this:

Newb Question: What's the difference between .h and .hpp files?
I'm assuming .hpp is where you would store a class? Since it has
source, and also declarations?

in the map.hpp:

extern int myMap[80][60];

and in the map.cpp:

#include "map.hpp"
int myMap[80][60] = {/*your hardcoded map goes here*/};


Ahh okay, that's what has to be done, I was unaware of using the
extern command to implement a global variable.


Remember that if you want to reference myMap from another .cpp file,
it has to bear the preprocessor command #include "map.hpp". This way
you should be OK.

When there are quite a few .hpp files to keep track of, make an
includes.hpp file and put all the #include commands there in the order
you need. Then, each .cpp file will only need this: #include
"includes.hpp". Easy.

Yea, I sort of started that already, I have define.h with all my
#defines in them which is included in my headers.h file.

One more thing. I may be misunderstanding you, but did you say that
Move() is a function? A global function? That's C, not C++. You can do
it this way, sure, but it's much more handy to make it a method within
a class. Declare the class and all its methods in the .hpp and then
write the implementation in the .cpp file. Trust me, it's the way to
go :).

It was my own function named Move(), not a global C function. Sorry
for the confusion.

Best of luck with your roguelike!

Thanks!
