Creating good waypoints

There are times when the number of waypoints must be reduced at a certain point during the game or just for memory constraints. In this recipe, we will learn a technique called condensation that helps us deal with this problem, forcing the waypoints to compete with each other given their assigned value.

Getting ready

In this recipe, we will deal with static member functions. It is important that we understand the use and value of static functions.

How to do it…

We will create the Waypoint class and add the functions for condensing the set of waypoints.

1. Create the Waypoint class, deriving not only from MonoBehaviour, but also 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 aforementioned interface:

   public int Compare(object a, object b)
   {
       Waypoint...
