Question

I’m creating a small game just like the game Reversi/Othello I have managed to created a 2×3 board with buttons.

The buttons change colour ones you click on them but I’m having trouble to detect if there is a white colour in between 2 black colours and if so change that white colour into black.. I hope this make sense. the buttons are in a 2D array. Any suggestions that could help me do this would be much appreciated.

Here is my code:

![namespace reversitest
{
    public partial class Form1 : Form
    {

        private Button\[,\] squares;
        public Form1()
        {
            InitializeComponent();

            squares = new Button\[3, 2\];
            squares = new Button\[,\] {{button1,  button2,  button3},
                {button4,  button5,  button6,}};
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            foreach (Button sqrr in squares)
            {
                sqrr.Click += new System.EventHandler(this.DrawCharacter);
            }
        }
        int _turn = 0;
        private void DrawCharacter(object sender, EventArgs e)
        {
            Button sqrr = (Button)sender;
            int col = 0;

            if (sqrr.BackColor.Equals(Color.Black) || sqrr.BackColor.Equals(Color.White))
            {
                MessageBox.Show("Move Not Allowed!");
            }
            else 
            {
               for ( int i = 0; i < squares.GetLongLength(1); ++i)
               {

                  // check othere squares and change color
                   if (i < 2)
                   {
                       for (int f = 0; f < 3; ++f)
                       {
                           var ss = squares\[i, f\];
                           if (ss.BackColor.Equals(Color.Black))
                           {

                               MessageBox.Show("we have a black");

                               //ss = squares\[i, f+1\];
                               ss.BackColor = Color.Black;

                           }
                           else
                           {
                               MessageBox.Show("no black");
                           } 
                       }

                   }

                       if (_turn == 0)
                       {
                           _turn = 1;
                           sqrr.BackColor = Color.Black;


                       }
                       else
                       {
                           _turn = 0;
                           sqrr.BackColor = Color.White;


                       } 

               }


            }


        }
    }
}

First name your buttons with the array index. It will help you to find the button.
For example according to you picture button1 name would be btn_1_1.

Then inside your button click event first get the button name and then identify the button positioned.

        Button b = sender as Button;
        string[] btnData = b.Name.Split('_');
        int x = int.Parse(btnData[1]);
        int y = int.Parse(btnData[2]);

        //check for possible combinations 
        int top = y - 2;
        int botton = y + 2;

        int left = x - 2;
        int right = x + 2;

        if (top >= 0 && squares[top, y].Background == Color.Black)
        {
            squares[top+1, y].Background = Color.Black;
        }  
        ...  
        ...   

Continue like that. If you need more detail please free to ask.
