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.

Profiling


When working with real-time products such as CryENGINE, programmers constantly have to consider the performance of their code. To aid in this, we'll be able to use the profile console variable.

The CVar allows for getting visual statistics on the most intensive parts of your code as shown in the following screenshot:

In the previous screenshot, profile was set to 1, the default mode, which sorts the most intensive functions being called for each frame.

Profile usages

Currently, the profile variable supports 13 different states as listed in the following table:

Value

Description

0

Default value; when this is set, the profiling system will be inactive.
