Unity 2018 Artificial Intelligence Cookbook - Second Edition

How to do it...

We will implement three different classes for handling low-level and high-level AIs, as follows:

1. Create the class for the basic rival agent, as shown in the following code:

using UnityEngine; 
 
public class RacingRival : MonoBehaviour 
{ 
    public float distanceThreshold; 
    public float maxSpeed; 
    public Vector3 randomPos; 
    protected Vector3 targetPosition; 
    protected float currentSpeed; 
    protected RacingCenter ghost; 
} 

2. Implement the Start function, as follows:

void Start() 
{ 
    ghost = FindObjectOfType<RacingCenter>(); 
} 

3. Define the Update function for handling the target position to follow, as shown in the following code:

public virtual void Update() { targetPosition = transform.position + randomPos; AdjustSpeed(targetPosition); ...
