Overview of this book

Procedural generation is a growing trend in game development. It allows developers to create games that are bigger and more dynamic, giving the games a higher level of replayability. Procedural generation isn’t just one technique, it’s a collection of techniques and approaches that are used together to create dynamic systems and objects. C++ is the industry-standard programming language to write computer games. It’s at the heart of most engines, and is incredibly powerful. SFML is an easy-to-use, cross-platform, and open-source multimedia library. Access to computer hardware is broken into succinct modules, making it a great choice if you want to develop cross-platform games with ease. Using C++ and SFML technologies, this book will guide you through the techniques and approaches used to generate content procedurally within game development. Throughout the course of this book, we’ll look at examples of these technologies, starting with setting up a roguelike project using the C++ template. We’ll then move on to using RNG with C++ data types and randomly scattering objects within a game map. We will create simple console examples to implement in a real game by creating unique and randomised game items, dynamic sprites, and effects, and procedurally generating game events. Then we will walk you through generating random game maps. At the end, we will have a retrospective look at the project. By the end of the book, not only will you have a solid understanding of procedural generation, but you’ll also have a working roguelike game that you will have extended using the examples provided.

Chapter 3. Using RNG with C++ Data Types

In Chapter 1, An Introduction to Procedural Generation, we learned the fact that pseudorandom number generation is at the heart of random procedural generation. Remember, a procedural system is not random by nature, we need to induce randomness. To start our journey, we're going to look at a range of different C++ data types, and use Random Number Generator (RNG) to give them random values at runtime. This ability to use core C++ data types in a random, yet still controlled, way will be the basis for all our future systems.

In this chapter we'll cover the following topics:

  • Setting the game seed
  • Enumerators
  • Setting Boolean values randomly
  • Accessing random elements in an array
  • Generating random strings
  • Random number distribution
