public static Board.Piece selectedPiece()

getPieceAt

public static Board.Piece getPieceAt(int p)

This method accesses the squares container and returns its piece

Parameters:

p - the position of the square to access

Returns:

The #Piece that is available, otherwise null

isOpponent

public boolean isOpponent(Board.Color other)

This method depicts whether the passed color is the opponent's

invalidateSquares

protected void invalidateSquares()

showMoves

protected void showMoves()

setUpMoves

public abstract void setUpMoves()

This is called each time a piece moves, and should use the MOVE constants (MOVE_UP, etc.). When assigning the
move values from 1 - 8, you can use a clockwise motion (move_1 - top left, move_2 - top, etc.). These moves
are used set up the direction of movement and final position of a move.
For example with the Knight in Knighted or Chess:

move_1 = fromCurPos(MOVE_UP_LEFT + MOVE_LEFT); // 6
move_2 = fromCurPos(MOVE_UP_LEFT + MOVE_UP); // 15

...etc.
