#include Puzzle

[Dark Goomba]

Hi everyone. I am working on a game that has a lot of files. The problem is that I don't think that I am including the header files in the right sequence, so some of the classes are undefined. The files are Battlefield.h, Creature.h, Enemy.h, Button.h. I've spent hours trying to code it so:

Battlefield.h  has Creature.h, Enemy.h, and Button.h defined.
Creature.h    has Enemy.h and Battlefield.h defined.
Enemy.h       has Creature.h and Battlefield.h defined.
Button.h       has Creature.h and Battlefield.h defined.

Thanks in advance.

The order of #include statements shouldn't matter and are a sign you are doing something wrong somewhere. Could you edit the OP with the contents of your header files? That might make the issue clearer, although I suspect this:
http://en.wikipedia.org/wiki/Forward_declaration
might be helpful reading.

As bottles already mentioned you should have a look at forward declaration, because you can't include a header which already includes this header... The compiler will give strange errors when you do this like i.e. this class is not defined....

Make sure each header file is self contained and has correct include guards.

Yes, all of the guard tags are properly used and the header files are self contained. I am just unsure which files should include what.

Edit: I tried the forward declarations and IT WORKED! Thanks everyone.
