Slt a tous,

j'essaye depuis un moment de coder le jeu connu sous le nom de "snake game" en c++ oriente objet ms il ne fonctionne pas entierement. Au fait, les touches de controle (a,  w, s et d) soit (gauche, haut, bas et droite) fonctionnent mais la tete de mon serpent materialise ici par 0 ne se deplace sur ma carte qd l'une de ces touches est appuyee. Ci-joint les differentes classes et enfin le fichier main.cpp.

//Classe de configuration
#ifndef DEF_SETUP
#define DEF_SETUP
enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
class Setup
{
public:
	Setup();
	~Setup();
	bool getStatus() const;
	int getWidth() const;
	int getHeight() const;
	void setStatus(bool status);
	eDirection m_dir;
private:
	const int m_width = 20;
	const int m_height = 20;
	int m_score;
	bool m_gameOver;
};
#endif // !DEF_SETUP

#include "Setup.h"
 
Setup::Setup() : m_gameOver(false), m_dir(STOP), m_score(0)
{
	
}


Setup::~Setup()
{
}

bool Setup::getStatus() const
{
	return m_gameOver;
}

int Setup::getWidth() const
{
	return m_width;
}

int Setup::getHeight() const
{
	return m_height;
}


void Setup::setStatus(bool status)
{
	m_gameOver = status;
}

// Classe de dessiner la carte
#ifndef DEF_DRAW
#define DEF_DRAW

{

	~Draw();
	void createMap();
	int m_x, m_y, m_fruitX, m_fruitY;
private:
	Setup mySet;
};
#endif // !DEF_DRAW



// Source file
#include "Draw.h"


using namespace std;

Draw::Draw()
{
	srand(time(0));
	m_x = mySet.getWidth() / 2;
	m_y = mySet.getHeight() / 2;
	m_fruitX = rand() % mySet.getWidth();
	m_fruitY = rand() % mySet.getHeight();
}


Draw::~Draw()
{
}


void Draw::createMap()
{
	system("cls");
	for (int i = 0; i < mySet.getWidth() + 1; i++)
	{
		cout << "#";
	}
	cout << endl;

	for (int i = 0; i < mySet.getHeight(); i++)
	{
		for (int j = 0; j < mySet.getWidth(); j++)
		{
			if (j == 0 || j == (mySet.getWidth() - 1))
				cout << "#";
			if (i == m_y && j == m_x)
				cout << "0";
			else if (i == m_fruitY && j == m_fruitX)
				cout << "F";
			else
				cout << " ";
		}
		cout << endl;
	}
	for (int i = 0; i < mySet.getWidth() + 1; i++)
	{
		cout << "#";
	}
	cout << endl;


}

// Classe pour deplacer le serpent

#ifndef DEF_LOGIC
#define DEF_LOGIC
#include <iostream>
#include "Setup.h"
#include "Draw.h"

	case UP:
		p.m_y++;
		break;
	case DOWN:
		p.m_y--;
		break;
	default:
		break;
	}
}

// Classe pour les touches de controle
#ifndef DEF_INPUT
#define DEF_INPUT
#include <iostream>
#include <conio.h>
#include "Setup.h"
#include "Draw.h"

using namespace std;
class Input

void Input::snakeControl()
{
	if (_kbhit()) 
	{
		switch (_getch())
		{

		}
	}
}

Le main.cpp ci-dessous:

#include <iostream>
#include "Setup.h"
#include "Draw.h"
#include "Input.h"
#include "Logic.h"

using namespace std;
int main()
{
	Setup s;
	Draw d;
	Input i;
	Logic l;
	while (!s.getStatus())
	{
		d.createMap();
		i.snakeControl();
		l.snakeMove();
	}
	return 0;
}

Je vous remercie d'avance.
