Hi Neo,
Sorry to be a pain, but I need some more help with the TickTackToe game... I know you love it really!

The problem I am having is calculating the winners on a diagonal, as it only recognises a diagonal win when on the center diagonals i.e. anywhere on the corner to corner(s)... nowhere else!

I have been looking through the code this morning but am going round in circles!

Ive just pasted the diagonal check code here, think ive already pasted the the rest previously. lol

Code: Select all

 // diag check
                if (P == 0){
                   str1 = "";
                   str2 = "";
                   for (x = 0; x < N; x++){
                        str1 += tickTackButton[x, x].Text; // forward
                        str2 += tickTackButton[x, N - 1 - x].Text; // backward
                   }

                   if (str1.IndexOf(comb_X) != -1 || str2.IndexOf(comb_X) != -1)
                   {
                      P = 1;
                      PlayerWins(P);
                   }
                   else if (str1.IndexOf(comb_O) != -1 || str2.IndexOf(comb_O) != -1)
                   {
                      P = 2;
                      PlayerWins(P);
                   }
                }

Had a quick look at that. I don't have much time today so you need to check this code.

Define these new variables.
Code: Select all
```
int len_comb, N1;
string str3, str4;
```
Fine following code.
Code: Select all
```
comb_O = arr_comb_O[gridSizeComboBox.SelectedIndex];
```
Add following code after that.
Code: Select all
```
len_comb = comb_X.Length;
```

This code needs to come after the diagonal check code.

Code: Select all

            // other cross dir check
            if (P == 0)
            {
                N1 = 1;

                for (y = 1; y < N; y++)
                {
                    for (x = N1; x < N; x++)
                    {
                        str1 += tickTackButton[x, x - N1].Text; // forward upper
                        str2 += tickTackButton[x - N1, x].Text; // forward lower

                        str3 += tickTackButton[x - N1, (N - 1) - x].Text;   // backward upper
                        str4 += tickTackButton[x, (N - 1) - (x - N1)].Text; // backward lower
                    }

                    if (str1.IndexOf(comb_X) != -1 || str2.IndexOf(comb_X) != -1 || str3.IndexOf(comb_X) != -1 || str4.IndexOf(comb_X) != -1)
                    {
                        P = 1;
                        PlayerWins(P);
                        break;
                    }
                    else if (str1.IndexOf(comb_O) != -1 || str2.IndexOf(comb_O) != -1 || str3.IndexOf(comb_O) != -1 || str4.IndexOf(comb_O) != -1)
                    {
                        P = 2;
                        PlayerWins(P);
                        break;
                    }
                    else
                    {
                        N1++;

                        if ((N - N1) < len_comb)
                        { // Not enough length to match
                            break;
                        }
                    }
                }
            }

Works sweat as a nut...!

I have been looking at Connect 4 source code trying to tackle it myself, but its very hard to try to unpick someone elses code, especially at my level!

When im working i'll have to put you on my pay roll..

Thanks "again" Neo.

You are welcome....

Always try to group things and find a combination. This is the way to simply coding...
