Preface

Game development is one of the most complex processes in the world as it requires a wide set of skills such as programming, math, physics, art, sound engineering, management, marketing, and many more. Even with modern technologies, it may take from a few hours to several years to create a game. This depends on the game complexity and tools available.

Computer games are usually based on a mix of simple concepts, which are turned into an enjoyable experience. The first step in making a good game is a game prototype. These can be made with the help of various game engines. However, learning how to use a game engine to the full extent may require you to study how it actually works. This way you have to rely on the available documentation and features that the game engine provides. Many game engines today provide a scripting language as a tool to implement certain game mechanics or to extend the game engine itself with new features.

The Lua programming language is gaining popularity in the game industry mainly due to its simplicity and efficiency. Most of the time, it's used only for simple tasks such as NPC dialogs, user interface, or custom game events. However, with additional Lua modules, you can create your own full-fledged game engine that can use almost all the capabilities of the modern computer hardware.

In this book, you'll find a set of recipes with solutions to the most common problems you may encounter while creating games with the Lua language.

The best way to learn something is to play with it. Therefore, each recipe is paired with simple demo applications that will help you understand the topic covered. You may even use these demo samples to create your own game prototype in no time.

All sample applications are available in the digital content of this book.
