Question

Conception card game

Asked by: epsilon777

Hie,
I am currently making a game (let' say a game of card), i have a problem of conception:

-Class CardGame represents the way the game will be played, turns between players, element used in the game(stacks, cards, players...) , and the main loop asking thier actions to the players.

-Class Player represents a local or distant player

Assume for the moment the program must be run in console mode, in the future a 3D layer will be added using a game engine.

Actually i have a dilemn and it does not seems to be nice: CardGame refers to Player and Players refers to CardGame that's why I think there is a problem of conception?

Any advice is welcome...

Any advice with problem of conception concerning threads and so on is welcome too, I will use a 3D engine like irrlicht in the future... which has his main loop (may be), so i wont be able to use mine, that's why i write about this problem too.

Thanks.

NB:All is done in c++.

I reply to myself:
May be putting a third class like a sessionmanager could be a solution:
Game------------Player
                 |
                 |
                 |
          SessionManager

The sessionmanager would know the players in the game and the game would interact with the sessionmanager to ask for the next command to execute??


Could it be a nice solution???

>> CardGame refers to Player and Players refers to CardGame

What excactly do you mean by that. Do you mean that both headers include each other. Then its really a problem.
If you mean Player is used in Game.cpp and Player is used in Game.cpp, thats fine.

I wouldnt use Game either, but for another reason. Game is very ambigious. Do you mean it handles the game-logic, the rules? Then I'd rather use GameLogic. Try to be as specific as you can. Its always good to say in one sentence, what a class is supposed to do. If you cant say it in one sentence, then you need to split it in more classes.

Session sounds good for handling all the objects the game needs and managing the communication between them.
SessionManager, sounds like it is a class that manages multiple sessions. If you mean that then ok, otherwise i would just use Session.

I would add a class like CardDeck, which will handles the visual representation later on, for starters it cound dump the cards in the console.

-The loop problem is still there, and the problem of loop in .h will still be there...
-But may be i can get rid of the problem of loop in conception in implementing an observer pattern

>>  and the problem of loop in .h will still be there...

If you just use a pointer or a reference to the other class in the header, then you dont need to include the other header, you can use a forward declaration, like this:

>>>> player.h begin <<<<

// forward declaration of class session, so we can use it here for refs and pointers
class Session;

class Player
{
public:
    Player() : session(NULL) {}

    SetSession(Session *s) { session = s; }

private:
    Session *session;
};

>>>> player.h end <<<<

Note: you cant actually dereference the session-pointer in the header, like
   
    session->AnyFunc();

But thats not a problem, you can do that in player.cpp and include "session.h" there


Hope it helps a bit :)

I know such declarations but for me it is quite the same : a bit uggly.
thanks

>> a bit uggly.

No, not at all. Of course it depends, what you actually do with the objects.
But forward declarations are not at all ugly.
