The smelling function using a graph-based system

In this recipe, we take a mixed approach to tag vertices with a given odor particle that collides with it.

Getting ready

The vertices should have a broad collider attached so that they catch the odor particles nearby.

How to do it...

1. Add the following member variable to the odor-particle script to store its parent ID:

public int parent; 

2. Create the new odor-enabled class, deriving from the original vertex:

using UnityEngine; 
using System.Collections; 
using System.Collections.Generic; 
 
public class VertexOdour : Vertex...
