[A Must-Know for Game Developers] Practical Game Mathematics

Why is all game math education always so difficult?

Game math for most game developers who don't need to dig into the engine internals!

• For those of us working with game engines, I've removed everything unnecessary and included only what's actually used.

  
  

• I support students' understanding and research through unlimited Q&A.

  
  

• I've included a video on "Math Research with AI". Let's go beyond even what we don't know.

• I focused everything on developing your 'practical game math skills'.
  I hope this course saves you time.

So why do we need game mathematics?

Can you logically explain 'magic'? Magic in novels or movies is irrational. But magic in games is different. We need to logically implement those irrational phenomena through code.

What's the secret? In the end, it's all 'mathematics.'

• Red Dead Redemption 2: The natural feel of never colliding when riding alongside NPCs (utilizing asymptotes and multiplication)

• Mjolnir's Return: The elegant curve of the hammer returning precisely to my hand (Bézier curve)

• 3D Maneuvering Gear: The physical sensation of rope being pulled taut (tension)

• Falcon 9 Landing: Simulation of landing at the precise angle (arctangent)

• Field of View Detection: How to know if an enemy is behind or in front of you (dot/cross product of vectors)

Beyond simple method calls, if you want to design and implement your own theories, game mathematics is essential.

However, many people get intimidated just by hearing the word "math." Even when you muster up the courage to open any game math book in Korea, it's filled with "engine internal logic" or "complex proofs", leaving you at a loss about how to actually apply it to your own game.

That's why I'm going to teach Korea's first practical game math used "on top of" game engines.

Complex engine internal theory? I threw it all out. I only included practical concepts you can actually use in real game development.

Formulas are all over the internet, and Unity does the calculations for us. We don't need to memorize formulas or calculate them ourselves. We focus only on 'how to apply them'.

My Beliefs

What will you gain after taking this course?

You'll be able to research the mathematical theories behind the algorithms you want.

You'll be able to implement many magical situations that need to happen within games.
I hope this course becomes a turning point in your life.

It's designed so that through AI, you'll learn to tackle even mathematical fields you don't know, enabling you to attempt techniques you haven't learned. Of course, you'll still need to study, but through AI, you'll be able to save a lot of time and understanding.

Unlike other courses, I've excluded all the math knowledge that's only used inside engines and unnecessary for the majority of engine users—such as polygons, projections, matrices, meshes, frustums, and quaternion calculations—and explained only the necessary knowledge, to the necessary extent.

• The math knowledge you've learned before, of course you can forget it and calculations? Of course you can make mistakes. This isn't a college entrance exam. You have the internet and a computer. I've captured the essence.

I'll show you practical examples for each technique!
