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.

Exercises

To help you test your knowledge of this chapter's content, here are a few exercises that you should work on. They are not imperative to the rest of the book, but working on them will help you assess your strengths and weaknesses in the material covered:

  1. There are many different algorithms available that could be used to generate mazes, such as the randomized Prim's algorithm and Kruskal's algorithm. Choose one of these algorithms and have a go at replacing the recursive backtracking implementation with your own implementation.
  2. We worked with quite a small level size. Try increasing it and varying the characteristics of the levels that are generated. Increase the number of rooms, their size, and so on.
  3. You may have noticed that our torches are missing! Since we no longer load the level from a level file, we need to add them ourselves. Torches should be placed on tiles of the TILE::WALL_TOP type. Have a go at creating this function yourself. If you get stuck, you can...
