problem with classes?

Try something like this:

#include "creatures.cpp"
#include "rooms.cpp"
class creature;
class room;
creature creatures[NUMBER_OF_CREATURES];
room rooms[NUMBER_OF_ROOMS];

EDIT: And why don't you use headers?

You need to use header files.

Ok, with Tornado''s I still get the problem because the instances are actually trying to be used inside the files, so then their both undeclared.

And I am using header files their just called within the seperate files,
e.g. the top of creatures.cpp has
#include "creatures.h"

ooh.. ooh.. it''s almost working, thank you guys helped see that I was doing it weird...

took the header files outside of those files and added them above, like

#include "creatures.h"
#include "rooms.h"
#include "creatures.cpp"
....

and then added extern room rooms[NUMBER_OF_ROOMS]; to creatures.cpp
and now it''s almost working... I''m not sure if the new problem is related to that, but thank you two.

First, make sure you have all your class declarations, defines, constants, prototypes in your header files.

If you have the files
creatures.h
creatures.cpp
rooms.h
rooms.cpp
gamemain.cpp

These are the only includes you would need:
In creatures.cpp
#include "creatures.h"
#include "rooms.h"

In rooms.cpp
#include "rooms.h"
#include "creatures.h"

In winmain.cpp
#include "rooms.h"
#include "creatures.h"

After you''ve done this, add all the .cpp and .h files into your main work space. This is important.

Make sure your headers have inclusion guards. Also, the first thing in your .cpp file should be the #include''s. Don''t put in any code until after all the #includes.

If you have correctly separated interface from implementation by putting only the interface in the header file you should have no problem.

Good luck!

oh bother, it compiles now, but it hangs at the beginning of the program,

all the info is saved in data files so at the beginning of main
it goes something like

In.open("creatures.data");
//loop that reads in info
In.close

//That part works fine, then there''s the room one which use to work, and is exactly the same as creatures (except for its rooms

Now I''m guessing it has to do with that extern I''m using..?
I have to get to a class right now so I don''t have time to try your suggestion until later tonight, but thank you Z01.
