Working with the game-tree class

The game state can be represented in a lot of different ways, but you will learn how to create extendible classes in order to use the high-level board AI algorithms for different circumstances.

Getting ready…

It is important to be clear on object-oriented programming, specifically on inheritance and polymorphism. This is because we'll be creating generic functions that can be applied to a number of board game decisions and then writing specific subclasses that inherit and further specify these functions.

How to do it…

We will build two classes in order to represent game-tree with the help of the following steps:

1. Create the abstract class Move:

   using UnityEngine;
   using System.Collections;
   
   public abstract class Move
   {
       
   }

2. Create the pseudo-abstract class Board:

   using UnityEngine;
   using System.Collections;
   
   public class Board
   {
       protected int player;
       //next steps here
   }

3. Define the default constructor:

   public Board()
   {
       player = 1;
   }

4. Implement...
