Learn C++ from scratch and get started building your very own games

About This Book

• This book offers a fun way to learn modern C++ programming while building exciting 2D games
• This beginner-friendly guide offers a fast-paced but engaging approach to game development
• Dive headfirst into building a wide variety of desktop games that gradually increase in complexity
• It is packed with many suggestions to expand your finished games that will make you think critically, technically, and creatively

Who This Book Is For

This book is perfect for you if any of the following describes you: You have no C++ programming knowledge whatsoever or need a beginner level refresher course, if you want to learn to build games or just use games as an engaging way to learn C++, if you have aspirations to publish a game one day, perhaps on Steam, or if you just want to have loads of fun and impress friends with your creations.

What You Will Learn

• Get to know C++ from scratch while simultaneously learning game building
• Learn the basics of C++, such as variables, loops, and functions to animate game objects, respond to collisions, keep score, play sound effects, and build your first playable game.
• Use more advanced C++ topics such as classes, inheritance, and references to spawn and control thousands of enemies, shoot with a rapid fire machine gun, and realize random scrolling game-worlds
• Stretch your C++ knowledge beyond the beginner level and use concepts such as pointers, references, and the Standard Template Library to add features like split-screen coop, immersive directional sound, and custom levels loaded from level-design files
• Get ready to go and build your own unique games!

In Detail

This book is all about offering you a fun introduction to the world of game programming, C++, and the OpenGL-powered SFML using three fun, fully-playable games. These games are an addictive frantic two-button tapper, a multi-level zombie survival shooter, and a split-screen multiplayer puzzle-platformer.

We will start with the very basics of programming, such as variables, loops, and conditions and you will become more skillful with each game as you move through the key C++ topics, such as OOP (Object-Orientated Programming), C++ pointers, and an introduction to the Standard Template Library. While building these games, you will also learn exciting game programming concepts like particle effects, directional sound (spatialization), OpenGL programmable Shaders, spawning thousands of objects, and more.

Style and approach

This book offers a fun, example-driven approach to learning game development and C++. In addition to explaining game development techniques in an engaging style, the games are built in a way that introduces the key C++ topics in a practical and not theory-based way, with multiple runnable/playable stages in each chapter.

Dedicated to everyone who has no place to stay or insufficient strength to live. Especially to those who used up all their strength serving someone else.

Preface

This book is about learning C++ programming the fun way. Starting from zero experience, you will learn the basics of C++, such as variables and loops, through to advanced topics, such as inheritance and polymorphism. Everything you learn will be put into practice building three fully-playable games.

These are our three projects for the book.

Timber!!!

The first game is an addictive, fast-paced clone of the hugely successful Timberman, http://store.steampowered.com/app/398710/. Our game, Timber!!!, will allow us to be introduced to all the C++ basics at the same time as building a genuinely playable game.

Zombie Arena

Next we will build a frantic, zombie survival-shooter, not unlike the Steam hit, Over 9,000 Zombies, http://store.steampowered.com/app/273500/. The player will have a machine gun, and must fight off ever growing waves of zombies. All this will take place in a randomly generated, scrolling world. To achieve this, we will learn about object-oriented programming and how it enables us to have a large code base (lots of code) that is easy to write and maintain. Expect exciting features such as hundreds of enemies, rapid-fire weaponry, pick-ups and a character that can be "leveled-up" after each wave.

Thomas was Late

The third game will be a stylish and challenging, single player and co-op puzzle platformer. It is based on the very popular game, Thomas was Alone, http://store.steampowered.com/app/220780/. Expect to learn cool topics such as particle effects, OpenGL Shaders, and split-screen cooperative multiplayer.

What this book covers

Chapter 1, C++, SFML, Visual Studio, and Starting the First Game, this is quite a hefty first chapter, but we will learn absolutely everything we need in order to have the first part of our first game up and running. Here is what we will do:

• Find out more about the games we will build
• Learn a bit about C++
• Explore SFML and its relationship with C++
• Look at the software, Visual Studio, that we will use throughout the book
• Set up a game development environment
• Create a reusable project template, which will save a lot of time
• Plan and prepare for the first game project, Timber!!!
• Write the first C++ code of the book and make a runnable game that draws a background

Chapter 2, Variables, Operators, and Decisions – Animating Sprites, in this chapter, we will do quite a bit more drawing on the screen, and to achieve this we will need to learn some of the basics of C++. Here is what is in store:

• Learn all about C++ variables
• See how to manipulate the values stored in variables
• Add a static tree, ready for the player to chop
• Draw and animate a bee and three clouds

Chapter 3, C++ Strings, SFML Time – Player Input, and HUD, in this chapter, we will spend around half the time learning how to manipulate text and display it on the screen, and the other half looking at timing and how a visual tim...
