Math for Game Developers is exactly what it sounds like - a weekly instructional YouTube series wherein I show you how to use math to make your games. Every Thursday we'll learn how to implement one game design, starting from the underlying mathematical concept and ending with its C++ implementation. The videos will teach you everything you need to know, all you need is a basic understanding of algebra and trigonometry. If you want to follow along with the code sections, it will help to know a bit of programming already, but it's not necessary.

Starting with the second series, "Advanced Vectors", you can download the source code that I'm using from GitHub, from the description of each video. If you have questions about the topics covered or requests for future topics, I would love to hear them! Leave a comment, or ask me on my Twitter, @VinoBS

# Intro to Vectors

These are really good tutorials

Exactly what I was looking for. Thanks.

I'm not a big fan of Video tutorials but this one is pretty nice for beginners.

Awesome tutorial! You draw really straight lines too haha

Haha,nice tutorial,nice straight lines.

These are very useful and well explained. It has helped me simplify my own code, initially I was doing good old soh cah toa math to work out angles, then using that angle to work out x and y distances based on the angle and length I wanted the vector to be. Lots of messing about. As soon as you mentioned how to normalize a vector I realized that all I needed to do from there is multiply the resultant vector by my speed factor. Thanks!

The lines are straight because in photoshop you can hold shift down and it makes a straight line. I can't really draw lines that straight.

Fantastic videos, many thanks!
