API

board

The board arrangement is represented by an array of arrays. Each of those subarrays represent one row, all containing the same number of integers. -1 denotes a white stone, 1 a black stone, and 0 represents an empty vertex.

Example

[[ 0, 0, 1, 0,-1,-1, 1, 0, 0],
 [ 1, 0, 1,-1,-1, 1, 1, 1, 0],
 [ 0, 0, 1,-1, 0, 1,-1,-1, 0],
 [ 1, 1, 1,-1,-1,-1, 1,-1, 0],
 [ 1,-1, 1, 1,-1, 1, 1, 1, 0],
 [-1,-1,-1,-1,-1, 1, 0, 0, 0],
 [ 0,-1,-1, 0,-1, 1, 1, 1, 1],
 [ 0, 0, 0, 0, 0,-1,-1,-1, 1],
 [ 0, 0, 0, 0, 0, 0, 0,-1, 0]]

Vertex

Board positions are represented by a vertex, i.e. an array of the form [x, y] where x and y are non-negative integers, zero-based coordinates. [0, 0] denotes the upper left position of the board.


class goBoard

Constructors

new Board(size, [signMap])

Properties

board.board

<BoardArr> - The underlying sign map of the board.

Stone Arrangement Functions

board.get(vertex)

Returns the sign at the given vertex.

board.set(vertex, sign)
  • vertex <Vertex>
  • sign <Integer> - One of -1, 0, or 1

Sets the sign at the given vertex. No validity checks will be made. This function mutates the board and returns this to enable chaining.

board.has(vertex)

Returns a boolean whether the given vertex is valid or can be found on the board.

board.putChess(vertex, sign)
  • sign <Integer> - One of -1, 0, or 1
  • vertex <Vertex>

Returns a new board instance that represents the board state after the player who corresponds to the given sign makes a move at vertex. The capture count will also be updated correctly. If board is valid then the new returned board instance will also be valid. This function will not mutate board. If sign is 0 or vertex not valid, this function will be equivalent to clone().
