Documentação das funções

checkBoundaries()

void checkBoundaries ( const int row, const int col )

private

Checks if the given row and column are within the boundaries of the board.

Parâmetros

row	The row index to check.
col	The column index to check.

Exceções

InvalidInputException

if the row or column is out of the board's boundaries.

checkDirection()

bool checkDirection ( const int row, const int col, char other, const Direction & dir )

private

Checks a specific direction from a given position on the board to find and mark opponent's pieces to be captured.

This function checks in the specified direction (given by dir) from the position (row, col) on the board. It looks for a sequence of opponent's pieces (other) that are bounded by the current player's piece. If such a sequence is found, the positions of the opponent's pieces are added to the list of pieces to be captured (toEat).

Parâmetros

row	The starting row position on the board.
col	The starting column position on the board.
other	The character representing the opponent's pieces.
dir	The direction to check, represented by a Direction object containing dx and dy.

Retorna

true if the direction is valid and contains opponent's pieces to be captured, false otherwise.

checkDirections()

void checkDirections ( const int row, const int col )

private

Checks all possible directions from a given position on the board.

This function iterates through all 8 possible directions (up, down, left, right, and the four diagonals) from the specified row and column on the board.

Parâmetros

row	The row index of the starting position on the board.
col	The column index of the starting position on the board.

checkPosition()

void checkPosition ( const int row, const int col )

private

Checks if the specified position on the board is occupied.

Parâmetros

row	The row index of the position to check.
col	The column index of the position to check.

Exceções

InvalidInputException

if the position is occupied.

isGameFinished()

char isGameFinished ( )

overridevirtual

Checks if the game of Reversi is finished.

This function determines if the game has ended by checking for valid moves for the current player. If no valid moves are found, it switches to the other player and checks again. If neither player has valid moves, the game is considered finished. The function then counts the pieces for each player on the board and returns the result.

Retorna

'E' if the game is not finished and there are valid moves. 'X' if player 'X' has more pieces and wins. 'O' if player 'O' has more pieces and wins. 'D' if the game is a draw (both players have the same number of pieces).

makeMove()

void makeMove ( )

overridevirtual

Executes a move in the Reversi game.

This function performs the following steps:

1. Determines the opponent's piece based on the current player.
2. Reads the move from the player.
3. Sets the player's piece on the board at the specified move position.
4. Checks all 8 possible directions from the move position to find and flip the opponent's pieces.
5. Flips the opponent's pieces to the current player's pieces if they are bounded by the current player's pieces.
6. Changes the current player to the opponent.

Array of possible directions for the Reversi game.

This array contains all the possible directions in which a move can be made in the Reversi game. Each direction is represented by a Reversi::Direction object, which takes two parameters indicating the change in row and column respectively.

Directions included:

• (-1, 1): Down-Left
• (0, 1): Down
• (1, 1): Down-Right
• (1, 0): Right
• (1, -1): Up-Right
• (0, -1): Up
• (-1, -1): Up-Left
• (-1, 0): Left
