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.

Analyzing waypoints by height


This recipe lets us evaluate a waypoint according to its position. Strategically speaking, lower positions are at a disadvantage. In this case, we will use a flexible algorithm to get the quality of a waypoint, given the heights of its surroundings.

Getting ready

This recipe is simple enough, so there is no extra content to be aware of. The algorithm is flexible enough to receive a list of positions, which is given by the waypoint's neighbors or just the complete graph of waypoints. The surroundings heuristic is kept outside for our perusal and it gives the game's specific design.

How to do it…

We will implement a function to evaluate a location given its height and its surrounding points:

  1. Declare the function for evaluating the quality:

    public static float GetHeightQuality (Vector3 location, Vector3[] surroundings)
    {
        // next steps
    }
  2. Initialize the variables for handling the computation:

    float maxQuality = 1f;
    float minQuality = -1f;
    float minHeight = Mathf.Infinity...
