Math For Video Games: The Fastest Way To Get Smarter At Math

Learn Math for Video Game Design & Coding through Solving Fun Video Game Problems

   Watch Promo

Maths and video games go hand-in-hand. Video games are a practical, challenging, and fun way to sharpen your math skills. What's more, video games are like living math. From graphics and physics, to AI and movement, games are full of math.

Learn foundational math concepts relevant to game development. In the course we break it down and build it back up, block by block. For each skill you will start from an interesting real-world problem. You'll always understand why you're learning a concept, and feel motivated to solve the problem in hand. In the course you will learn:

  • How to write and solve equations relevant to game development.
  • Basic trigonometry the fun way, triangles, circles & stuff.
  • Enough vector math to make 2D and 3D games.
  • About imaginary & complex numbers, angles & quaternions.

The concepts learnt will help you create interesting scoring mechanics, have one object smoothly follow another, calculate the path of a projectile, target enemies using triangles and understand how random item drops work.

This course is the result of a successful Kickstarter, and consistent demand from our community of hundreds of thousands of students worldwide. There is a real need to improve math skills, not just for games, but for many areas of life. You'll be amazed how much more colourful the world looks as your math improves.

All the math you learn will be reinforced with quizzes. You'll write your own handwritten notes as you go, to help you remember your skills. We'll translate some of the math to pseudocode so you can see how it applies to C#, C++, Python and any other modern language.

Benefit from our world-class support from both other students, and the GameDevtv team who are regularly engaged in the forums and Q&A section.

You will get full lifetime access for a single one-off fee. The creators are qualified and experienced coders and avid gamers, so are able to explain complex concepts clearly, as well as entertain along the way.

This course is still in development, with new content dropping on a weekly basis.

Join us on this exciting journey now, you won't be disappointed!
