Usage

Importing

import { Game, StoneColor } from 'weiqi-engine';

Basic Example

// Create players
const blackPlayer = {
  name: 'First player',
  color: StoneColor.BLACK,
  capturedStones: 0,
};
const whitePlayer = {
  name: 'Second player',
  color: StoneColor.WHITE,
  capturedStones: 0,
};

// Create a new game (19x19 board by default)
const game = new Game(19, blackPlayer, whitePlayer);

// Make a move (Black plays at (3, 3))
const move = { position: { x: 3, y: 3 }, color: StoneColor.BLACK };
const result = game.makeMove(move);
console.log(result.success, result.message);

// Get current board state as string
console.log(game.getBoard().toString());

// Get whose turn it is
console.log('Current turn:', game.getCurrentTurn());
