How to do it...

We will create the Waypoint class and add the methods for condensing the set of waypoints:

1. Create the Waypoint class, deriving from both MonoBehaviour and from the IComparer interface:

using UnityEngine;using System.Collections;using System.Collections.Generic;public class Waypoint : MonoBehaviour, IComparer{  public float value;  public List<Waypoint> neighbours;}

2. Implement the Compare function from the interface:

public int Compare(object a, object b){  Waypoint wa = (Waypoint)a;  Waypoint wb = (Waypoint)b;  if (wa.value == wb.value)    return 0;  if (wa.value < wb.value)    return -1;  return 1;}

3. Implement the static function that checks whether an agent is able to reach one waypoint from the other:

public static bool CanMove(Waypoint ...
