Member Data Documentation

◆ b_capturedPieces

CapturedT tt::Board::b_capturedPieces

protected

List of captured pieces.

Pieces that have retired and have been removed from Board should go to this list. The default applyTurn() function does that if turn captures something.

protected

Current turn color variable.

See also: currentTurn()

◆ b_history

HistoryT tt::Board::b_history

protected

Board history of applied Turn objects.

All turn objects that have been passed to applyTurn() function go to that list by default with help of Turn::clone().

See also: history(), HistoryT

◆ b_pieceGetter

PieceGetterT tt::Board::b_pieceGetter

protected

Piece getter variable.

This variable keeps the functor for getting the new user-reuqested Piece std::type_index.

This could be useful for example in chess game, when pawn reaches the end of the board and player have to choose the piece to exchange it for.

◆ b_turnIndex

std::size_t tt::Board::b_turnIndex = 0

protected

Current turn index.

This varriable is incremented each time the Turn::apply() is called on Piece that belongs to current Board object.
