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 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 we'll be writing specific sub-classes that inherit and further specify these functions.

How to do it...

We will build two classes 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...
