C++ Game Development By Example

By: Siddharth Shekar

Overview of this book

Although numerous languages are currently being used to develop games, C++ remains the standard for fabricating expert libraries and tool chains for game development. This book introduces you to the world of game development with C++. C++ Game Development By Example starts by touching upon the basic concepts of math, programming, and computer graphics and creating a simple side-scrolling action 2D game. You'll build a solid foundation by studying basic game concepts such as creating game loops, rendering 2D game scenes using SFML, 2D sprite creation and animation, and collision detection. The book will help you advance to creating a 3D physics puzzle game using modern OpenGL and the Bullet physics engine. You'll understand the graphics pipeline, which entails creating 3D objects using vertex and index buffers and rendering them to the scene using vertex and fragment shaders. Finally, you'll create a basic project using the Vulkan library that'll help you get to grips with creating swap chains, image views, render passes, and frame buffers for building high-performance graphics in your games. By the end of this book, you’ll be ready with 3 compelling projects created with SFML, the Vulkan API, and OpenGL, and you'll be able take your game and graphics programming skills to the next level.

3D coordinate systems

Before we can specify a location, we have to specify a coordinate system. A 3D coordinate system has three axes: the x axis, the y axis, and the z axis. These three axes start from the origin of where the three axes intersect.

The positive x axis starts from the origin and starts moving endlessly in a certain direction, while the negative x axis moves in the opposite direction. The positive y axis starts from the origin and moves in an upward direction at 90 degrees to the x axis, and the negative y axis moves in the opposite direction. This describes a 2D XY plane, which forms the basis of a 2D coordinate system.

The positive z axis starts from the same origin as the x and y axes and is perpendicular to the X and Y axes. The positive z axis can go in either direction of the XY plane in order to form a 3D coordinate system.

Assuming that the positive x axis...
