Game Math Series: Dot Product | Learn Game Math in Unity3D | Unity Tutorial
In the first episode of the Game Math Series in Unity, we will learn about the dot product, which is one of the most important math topics for all game developers. We will explore both definitions of the dot product: the algebraic definition and the geometric definition. Additionally, we will cover vector normalization, learn how to interpret the dot product result and explore various examples. We will discuss the theory of AI line of sight and see an implementation in Unity3D, followed by another practical example in Unity: the backstab mechanic.
Throughout this series, we'll delve into various math topics, starting with the dot product, which will serve as a foundation for other essential concepts. Upcoming topics include vector projection, vector reflection, and the distinctions between lines, line segments, and rays, both in mathematics and in game development with Unity.
