阅读棋盘后在Unity中创建FEN字符串

Question

我使用C#在Unity中制作了一个功能齐全的国际象棋游戏。现在我想添加AI，对于国际象棋引擎，我选择了Stockfish。我在游戏中安装了引擎，但它什么也没做，因为它无法与棋盘通信。

要进行通信，我需要每行创建一个FEN字符串，从左上角开始，FEN字符串如下所示：

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

小写是黑色的棋子，大写的白色棋子，数字是黑色的空格，w表示白色的下一个转弯，KQkq表示可用的施法，-表示通过是可用的，0 1个移动次数。

有没有人知道创建和操作字符串以制作FEN字符串的教程或提示？

我将把我到目前为止所做的代码粘贴到Stockfish进程中，我没有做任何与FEN字符串相关的事情，因为我真的不知道如何启动它。

欢迎任何链接或提示

void RunProcess()

{

    ProcessStartInfo startInfo = new ProcessStartInfo();

    startInfo.UseShellExecute = false;

    startInfo.RedirectStandardInput = true;

    startInfo.RedirectStandardOutput = true;

    startInfo.RedirectStandardError = false;

    startInfo.CreateNoWindow = true;

    startInfo.FileName = Application.streamingAssetsPath + "/stockfish_9_x64.exe";

    Process process = new Process();

    process.StartInfo = startInfo;

    process.Start();

    string output;

    process.StandardInput.WriteLine("uci");

    process.StandardInput.WriteLine("isready");

    process.StandardInput.WriteLine("position fen rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1");

    process.StandardInput.WriteLine("go");

    process.StandardInput.WriteLine("stop");

    process.StandardInput.WriteLine("quit");

    do

    {

        output = process.StandardOutput.ReadLine();

    } while (!output.Contains("move"));

    UnityEngine.Debug.Log(output);

}

void OnMouseDown()

{

    RunProcess();

}

Answer 1

只是为了获得基本部分，你可以做这样的事情（注意：未测试）：public enum ChessPieces{&nbsp; &nbsp; King, Queen, Rook, // ... etc.&nbsp;}public class ChessPiece : MonoBehavior{&nbsp; &nbsp; public string FenId { get; }&nbsp; &nbsp; private readonly Dictionary<ChessPiece, string> FenIds = {&nbsp; &nbsp; &nbsp; &nbsp; { ChessPieces.King, "K" },&nbsp; &nbsp; &nbsp; &nbsp; { ChessPieces.Queen, "Q" },&nbsp; &nbsp; &nbsp; &nbsp; // ... etc.&nbsp; &nbsp; };&nbsp; &nbsp; // assuming you create the set of pieces programatically, use this constructor&nbsp; &nbsp; public ChessPiece(ChessPiece piece, ChessColor color)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; FenId = color == ChessColor.Black&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ? FenIds[piece].ToLower()&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : FenIds[piece].ToUpper();&nbsp; &nbsp; }}然后，假设您将电路板存储在行数组中，将布局转储到一个字符串中，我可能会在我的类上覆盖（也未经过测试）：ToStringChessBoard// somewhere in your code set the board up_chessBoard.Rows.Add(new [] {&nbsp; &nbsp; new ChessPiece(ChessPieces.Rook, ChessColor.Black),&nbsp; &nbsp; new ChessPiece(ChessPieces.Knight, ChessColor.Black),&nbsp; &nbsp; // ... etc.&nbsp; &nbsp; })_chessBoard.Rows.Add(new [] { /* next row ... */ });// ... etc.// to create your output, put this into the override of ToString:var output = ""; // should be StringBuilder, but for clarity and since this isn't likely performance limiting...var rowIndex = 0;foreach (var row in _chessBoard.Rows){&nbsp; &nbsp; rowIndex++;&nbsp; &nbsp; var blankSpaces = 0;&nbsp; &nbsp; foreach(var piece in row)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; if (piece == null)&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; blankSpaces++;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; else&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; output += blankSpaces == 0&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ? piece.FenId&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; : string.Format("{0}{1}", blankspaces, piece.FenId);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; blankSpaces = 0;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; if (blankSpaces > 0)&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; output += blankSpaces;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; if (rowIndex != 8)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; output += "/";&nbsp; &nbsp; }}此时，您已经在字符串中获得了基本布局，并且应该具有添加其他FEN字段的基本想法。我应该注意，我已经选择了一组数组来存储您的电路板。这可能不是最有效的存储机制（即在最好的情况下，你存储了50%的空值，这些值只会随着游戏的进行而增加），但是由于我们只谈论总共64个项目，因此我们可能在内存上没问题。
