Unity 2018 Artificial Intelligence Cookbook - Second Edition

How to do it...

We need to create three classes, Steering, AgentBehaviour, and Agent:

1. Steering serves as a custom data type for storing the movement and rotation of the agent:

using UnityEngine; 
public class Steering 
{ 
  public float angular; 
  public Vector3 linear; 
  public Steering () 
  { 
    angular = 0.0f; 
    linear = new Vector3(); 
  } 
} 

2. AgentBehaviour is the template class for most of the behaviors covered in this chapter:

using UnityEngine; public class AgentBehaviour : MonoBehaviour { public GameObject target; protected Agent agent; public virtual void Awake () { agent = gameObject.GetComponent<Agent>(); } public virtual void Update () { agent.SetSteering(GetSteering()); } public virtual Steering GetSteering () { return new Steering(); } }  ...
