#ifndef BOARD_H
#define BOARD_H

#include <SFML/Graphics/RenderWindow.hpp>
#include <SFML/Graphics/RectangleShape.hpp>
#include <SFML/Graphics.hpp>

#define numOfCellsH 4
#define numOfCellsW 4
#define cellHeight 128
#define cellWidth 128
#define margin 10

class board
{
public:
    board(sf::RenderWindow* window);
    ~board();
    void drawCellsBackground();
    void drawBoard();


private:
    sf::RenderWindow* mWindow;

    sf::RectangleShape mBoardBox;
    sf::RectangleShape mCellsBg;
};

gdb output :

Code: [Select]


Error in `/home/kachan/work/build-2048-Debug/2048': malloc(): smallbin double linked list corrupted: 0x00000000007b7180 ***

then i try

#ifndef BOARD_H
#define BOARD_H

#include <SFML/Graphics/RenderWindow.hpp>
#include <SFML/Graphics/RectangleShape.hpp>
#include <SFML/Graphics.hpp>

#define numOfCellsH 4
#define numOfCellsW 4
#define cellHeight 128
#define cellWidth 128
#define margin 10

class board
{
public:
    board(sf::RenderWindow* window);
    ~board();
    void drawCellsBackground();
    void drawBoard();


private:
    sf::RenderWindow* mWindow;

    sf::RectangleShape mBoardBox;
   // sf::RectangleShape mCellsBg;
};

and it works

Show the code where you initialize the variables.

program down before i init something, because

#include "board.h"

#include <SFML/Graphics/RenderWindow.hpp>
#include <SFML/Graphics/RectangleShape.hpp>

board::board(sf::RenderWindow *window)
{
    mWindow = window;

//    mBoardBox = new sf::RectangleShape;
    mBoardBox.setSize(sf::Vector2f(((numOfCellsW+1) * margin) + (cellWidth * numOfCellsW),
                                   ((numOfCellsH+1) * margin) + (cellHeight * numOfCellsH)));
    mBoardBox.setPosition(19, 160);
    mBoardBox.setFillColor(sf::Color(187, 173, 160, 255));

//    mCellsBg = new sf::RectangleShape;
//    mCellsBg.setSize(sf::Vector2f(cellWidth, cellHeight));
//    mCellsBg.setFillColor(sf::Color(205, 192, 180, 255));
}

board::~board()
{
}




void board::drawCellsBackground()
{

}

void board::drawBoard()
{
    mWindow->draw(mBoardBox);
//    mWindow->draw(mCellsBg);
}
