在随机行和列中排列对象

Question

    private void InitialSetup()
    {
        AddPiece(whiteRook, white, 0, 0);
        AddPiece(whiteKnight, white,1,2);
        AddPiece(whiteBishop, white,2,0);
        AddPiece(whiteQueen, white, 3,4);
        AddPiece(whiteKing, white, 4, 6);
        AddPiece(whiteBishop, white,5,0);
        AddPiece(whiteKnight, white,6,3);
        AddPiece(whiteRook, white, 7, 6);
    }
 
    public void AddPiece(GameObject prefab, Player player, int col, int row)
    {
        GameObject pieceObject = board.AddPiece(prefab, col, row);

        player.pieces.Add(pieceObject);
        pieces[col, row] = pieceObject;
    }

8 列 6 行

我有 48 个游戏对象，我希望它们在每次游戏开始时随机排列成行和列，但是如何使用 addPiece 方法做到这一点？

使用以下：

           Random rand = new Random();
            //create an array from 0 to 47 with each number occurring once
            int[] randomNumbers = Enumerable.Range(0, 48)
                .Select(x => new { x = x, rand = rand.Next() })
                .OrderBy(x => x.rand)
                .Select(x=> x.x)
                .ToArray();
            int[,] matrix = new int[6,8];
            for (int i = 0; i < 48; i++)
            {
                //rows and columns start at index zero
                int row = randomNumbers[i] / 8;
                int col = randomNumbers[i] % 8;
                matrix[row, col] = i;
            }
