Overview of this book

Unity 5 comes fully packaged with a toolbox of powerful features to help game and app developers create and implement powerful game AI. Leveraging these tools via Unity’s API or built-in features allows limitless possibilities when it comes to creating your game’s worlds and characters. This practical Cookbook covers both essential and niche techniques to help you be able to do that and more. This Cookbook is engineered as your one-stop reference to take your game AI programming to the next level. Get to grips with the essential building blocks of working with an agent, programming movement and navigation in a game environment, and improving your agent's decision making and coordination mechanisms - all through hands-on examples using easily customizable techniques. Discover how to emulate vision and hearing capabilities for your agent, for natural and humanlike AI behaviour, and improve them with the help of graphs. Empower your AI with decision-making functions through programming simple board games such as Tic-Tac-Toe and Checkers, and orchestrate agent coordination to get your AIs working together as one.

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
    {
        private Dictionary<int, OdourParticle> odourDic;
    }
  3. Initialize the odor dictionary in the proper function:

    public void Start()
    {
        odourDic = new Dictionary<int, OdourParticle>();
    }
  4. Add the odor to the vertex's dictionary:

    public void OnCollisionEnter(Collision coll)
    {
        OdourOdourParticle op;
        op = coll.gameObject.GetComponent<OdourParticle>();
        if (op == null)
            return;
        int id = op.parent;
        odourDic...
