A C# class library for the game of Go (a.k.a Igo, Weiqi, Baduk).
To start a new game, create a GameInfo object, specify the handicap, the board size,
the starting player and the komi in it. Then create a Game object using the GameInfo
parameter constructor.
Example:
GameInfo gi = new GameInfo() { Handicap = 2, StartingPlayer = Content.White };
Game game = new Game(gi);To make a move, call the MakeMove method on a game object. The method will return a
new game object representing the state of the game after the move. The current
implementation accepts all moves, including suicide, overwrite and super-ko violating
moves.
As shown, there are overloads of the MakeMove method which set an out bool parameter
with true or false depending on the legality of the move.
Example:
bool legal;
Game postMove = game.MakeMove(3, 3, out legal);To start a variation sub-game, call MakeMove on any Game node in the tree. All
variations are recorded in the game tree, and may be exported to SGF.
To set up a board position without going through all the moves, you can use setup moves
instead. Setup moves are not checked for legality; they can overwrite, create groups
with no liberties, etc. They are used, for example, to set up a life-and-death go
problem, or to show common patterns that appear in game. To use setup moves call the
SetupMove method on a game object.
Example 1: Setting up a free-placed handicap:
GameInfo gi = new GameInfo() { StartingPlayer = Content.White };
Game g = new Game(gi);
g.SetupMove(3, 3, Content.Black); // Place a black stone on the lower left star point.
g.SetupMove(9, 9, Content.Black); // Place a black stone in the center of the board.
g.SetupMove(3, 15, Content.Black); // Place a black stone in the upper left star point.
Console.WriteLine(g.SerializeToSGF(null));When exporting to SGF, the setup moves will appear correctly:
