const quint64 *

keys = nullptr

)

Creates a new uninitialized WesternZobrist object.

Parameters

keys	An array of zobrist keys that can be used instead of the random numbers generated by the Zobrist class.

Member Function Documentation

castling()

quint64 Chess::WesternZobrist::castling ( int side, int square ) const

virtual

Returns the zobrist value for player side's castling rook at square.

enpassant()

quint64 Chess::WesternZobrist::enpassant ( int square ) const

virtual

Returns the zobrist value for an en-passant target at square.

initialize()

void Chess::WesternZobrist::initialize ( int squareCount, int pieceTypeCount )

virtual

Initializes the zobrist numbers.

Parameters

squareCount	The number of squares the board has, including the invisible "Wall" squares.
pieceTypeCount	The number of piece types the variant has, including the empty "NoPiece" type (type 0).

Note

Subclasses that reimplement this function must call the base implementation.

Reimplemented from Chess::Zobrist.

piece()

quint64 Chess::WesternZobrist::piece ( const Piece & piece, int square ) const

virtual

Returns the zobrist value for piece at square.

Reimplemented from Chess::Zobrist.

side()

quint64 Chess::WesternZobrist::side ( ) const

virtual

Returns the zobrist value for side to move. This value must be in the key on black's turn.

Reimplemented from Chess::Zobrist.
