Overview of this book

CryENGINE is a complete 3D game development solution that can run on multiple platforms. It is orientated around giving intuitive tools to the developer. A variety of interactive video games can be created using CryENGINE. CryENGINE is one of the most beginner-friendly engines out there to learn. If you are interested in diving into the various systems and understanding their workings in a way that is easily understood, then this book is for you. This book provides you with the knowledge to tame the powerful but hard-to-master CryENGINE. CryENGINE Game Programming with C++, C#, and Lua dives into the various systems and explains their workings in a way that can be easily understood by developers of all levels. It provides knowledge on the engine along with step-by-step exercises and detailed information on the backend implementation of the subsystems, giving you an excellent foundation to build upon when developing your own CryENGINE games. Written by developers with years of CryENGINE experience, this book breaks down the common confusion that encompasses the CryENGINE engine code, guiding you through a series of chapters aimed towards giving you the ability to create your own games in a rapid yet productive fashion. You will learn everything you need to know in order to create your own CryENGINE-powered games as well as detailed information on how to use the engine to your advantage. By teaching systems such as audio, particle effects, rendering, AI, networking, and more, we'll be exposing the most inner parts of CryENGINE that commonly confuse programmers. If you want to quickly gain the knowledge required to create your own CryENGINE game title, then this book is for you.

Creating a basic game mode in C#


Now that we have the basic knowledge required to create a mini-game, why not do so? To start off, we'll aim towards creating a very basic system for spawning actors and entities.

Defining our intention

To start, let's clarify exactly what we want to do:

  1. Spawn our actor.

  2. Assign our actor to one of the two possible teams.

  3. Check when an actor enters the opposite team's Headquarters entity, and end it.

Creating the actor

The first thing we need to do is spawn our actor, which can't be done before we have one. To do this, we'll need to create a MyActor.cs file somewhere in the Game/Scripts directory and then add the following code:

  public class MyActor : Actor 
  {
  }

This code snippet is the bare minimum required for an actor to be registered.

We should also update our actor's view, to make sure the player sees something when entering the game.

  protected override void UpdateView(ref ViewParams viewParams)
  {
    var fov = MathHelpers.DegreesToRadians(60);

    viewParams...
