Face.h and Face.cpp The class Face gives you the possibility to line up 9 _Tile_s to form one Face of a Rubics Cube. It also contains methods to rotate the Faces and a getter and setter to manipulate the single Tiles.

Face.h


class Face
{
private:
    Tile* f_tiles;
public:
    //Constructors and Destructor
    Face(int color = -1);
    Face(const Face& f);
    ~Face();

    //Face Rotation
    void rotateRight();
    void rotateLeft();
    
    //Get Tile and Set Tile Color at specific row and col
    int getTileColor(int index) const;
    void setTileColor(int index, int color);
};

Face.cpp


// Create a uniform Face with same color.
Face::Face(int color)
{
    f_tiles = new Tile[9];
    
    for(int i = 0; i < 9; i++)
    {
        f_tiles[i].setColor(color);
    }
}

The above Method is the standard constructor. It creates an array of 9 Tiles in f_tiles. It then sets the color of each tile given by the argument in the constructors header.


//Copy Constructor
Face::Face(const Face& f)
{
    f_tiles = new Tile[9];
    
    for(int i = 0; i < 9; i++)
    {
        f_tiles[i].setColor(f.getTileColor(i));
    }
}

This copy Constructor creates a deep copy of one object, so tat the same object isn't referenced.


// Destructor
Face::~Face()
{
    delete [] f_tiles;
}

The destructor cleans up the memory taken by f_tiles.


// Rotate whole face by -90°
void Face::rotateRight()
{
    //Make temporary copy of the face
    Face* temp = new Face(*this);
    
    //Perform the changes
    this->setTileColor(0, temp->getTileColor(6));
    this->setTileColor(1, temp->getTileColor(3));
    this->setTileColor(2, temp->getTileColor(0));
    
    this->setTileColor(3, temp->getTileColor(7));
    this->setTileColor(4, temp->getTileColor(4));
    this->setTileColor(5, temp->getTileColor(1));
    
    this->setTileColor(6, temp->getTileColor(8));
    this->setTileColor(7, temp->getTileColor(5));
    this->setTileColor(8, temp->getTileColor(2));
    
    delete temp;
}

//Rotate face by 90°
void Face::rotateLeft()
{
    //Make temporary copy of the Face
    Face* temp = new Face(*this);
    
    //Perform the changes
    this->setTileColor(0, temp->getTileColor(2));
    this->setTileColor(1, temp->getTileColor(5));
    this->setTileColor(2, temp->getTileColor(8));
    
    this->setTileColor(3, temp->getTileColor(1));
    this->setTileColor(4, temp->getTileColor(4));
    this->setTileColor(5, temp->getTileColor(7));
    
    this->setTileColor(6, temp->getTileColor(0));
    this->setTileColor(7, temp->getTileColor(3));
    this->setTileColor(8, temp->getTileColor(6));
    
    delete temp;
}

int Face::getTileColor(int index) const
{
    return f_tiles[index].getColor();
}

void Face::setTileColor(int index, int color)
{
    f_tiles[index].setColor(color);
}
