Vectors and Intersections in Game Development

Overview

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. This course introduces you to two foundational concepts in game development: vectors and intersections. Understanding vectors allows you to handle movement, rotation, and transformations in both 2D and 3D spaces, which are essential in game mechanics and graphics. Intersections, on the other hand, are crucial for calculating collisions, raycasting, and physics simulations, ensuring that your game worlds respond realistically. You will start by learning the fundamentals of vectors, including operations such as the dot and cross products, normalization, and how to use them for rotating and moving objects. As you move through the course, you'll build practical skills with real-world challenges, such as creating a 2D look-at function or transforming objects in 3D. The course will then transition to intersection techniques, starting with basic line-segment intersections and moving to more advanced concepts like planes, reflections, and projections. By applying these in Unity, you'll deepen your understanding of how game engines use intersections for collision detection and object placement. This course is ideal for anyone interested in game development, 3D graphics, or computer programming. It’s especially beneficial for intermediate-level developers who are familiar with basic programming concepts and want to expand their skill set. The course assumes you have some prior knowledge of game development and programming, especially in C# and Unity. By the end of the course, you will be able to apply vector math to game objects in both 2D and 3D spaces, solve intersection problems between lines and planes, and implement these skills using Unity to create realistic game mechanics and interactions.

Syllabus

Vectors

In this module, we will dive deep into the core concept of vectors, exploring their importance in game development. You'll learn how to manipulate vectors for movement, rotations, and other transformations, both in 2D and 3D spaces. By mastering these vector operations, you will gain the skills to implement efficient mechanics for games, such as object movement and rotation toward targets.

Intersections

In this module, we will focus on the mathematical principles of geometric intersections, covering how to handle line-line, line-plane, and other intersection types in both 2D and 3D space. You'll explore practical applications such as collision detection and game physics, as well as how Unity implements these calculations. This section will equip you with the tools to manage spatial interactions between objects in a game world effectively.
