Mathematics for Computer Games Development using Unity

Mathematics for Computer Games Development using Unity. A Beginner’s Guide to Essential Mathematics, Data Structures and Algorithms used in Game Programming applied in Unity

Did you know computer games use mathematics to perform every single task, from rendering to animation and physics to AI?  Mathematics is everywhere.  A fundamental understanding of mathematics is critical in every occupation and nowhere is it more important than in games development. It underpins all primary operations performed by a game engine.  You can’t even move a character across the screen without it.  Keen to learn more and build up your knowledge in mathematics to improve your game development skills?  Then this course is for you.

In this course you will build your own C# classes to work with the geometrical constructs of 2D and 3D space that will develop your understanding of positioning and moving game objects. In short you will build your own maths library to replicate some of Unity’s Vector2, Vector3, Matrix4x4 and some Mathf methods.  Throughout, we will be using the Unity Game Engine to help emphasise the mathematics concepts.
