Implementing a tic-tac-toe rival

In order to make use of the previous recipes, we will devise a way to implement a rival for a popular game: tic-tac-toe. Not only does it help us extend the base classes, but it also gives us a way to create rivals for our own board games.

Getting ready…

We will need to create a specific move class for the tic-tac-toe board derived from the parent class we created at the beginning of the chapter:

using UnityEngine;
using System.Collections;

public class MoveTicTac : Move
{
    public int x;
    public int y;
    public int player;

    public MoveTicTac(int x, int y, int player)
    {
        this.x = x;
        this.y = y;
        this.player = player;
    }
}

How to do it…

We will create a new class, deriving it from Board, override its parent's methods, and create new ones.

1. Create the BoardTicTac class, deriving it from Board, and add the corresponding member variables for storing the board's values:

   using UnityEngine;
   using System;
   using System.Collections...
