Creating the abstract FSM class

Next, we implement a generic abstract class to define the enemy tank AI class's methods. This abstract class will be the skeleton of our AI and represent a high-level view of what an enemy tank should do.

We can see the code of this class in the FSM.cs file:

using UnityEngine;
using System.Collections;
public class FSM : MonoBehaviour {
    protected virtual void Initialize() { } 
    
    protected virtual void FSMUpdate() { } 
    
    protected virtual void FSMFixedUpdate() { }
    // Use this for initialization 
    void Start () {
        Initialize();
    }
    // Update is called once per frame 
    void Update () {
        FSMUpdate();
    ...
