There's plenty of tutorials on learning maths for gamedev, but why and where is this maths actually useful? Here, I try to give examples of how and when different types of mathematics pop-up, and how they are actually used when making a game. I have added links throughout the video and below if you want to learn these topics in more detail, but hopefully this will make you aware of the different areas of maths used in gamedev!
----------
Tutorials and Learning Resources for each topic covered (I have tried to include one video, one blog and one interactive thing to account for different types of learners!):
Numbers
+, -, x and ÷ are used frequently! The good thing here is that even if you aren't the best at doing sums quickly, the computer is! As long as you recognise when you should be using each operation, you'll be fine (e.g. subtract some health when your player takes damage).
Brush up on BODMAS! It's important to know what order more complicated calculations will calculate in - while remembering that you can use brackets to specifically order the way a sum will resolve: www.skillsyouneed.com/num/bod...
Discrete Maths
An umbrella term for lots of maths. Wikipedia splits it into 17 sub-topics (which are all individually still very broad): en.wikipedia.org/wiki/Discret...
You will almost definitely do a discrete maths course at university, if you do CompSci or a related degree. You could learn about any of these sub-topics for years.

To add to your list: I would say *Probability* theory and *Statistics* are pretty crucial for system design and making the numbers work for you (and also for understanding the analytics once you release your game). *Physics* , or classical mechanics and galilean relativity at least, is definately up there too if you're making anything real-time. And by extension, *Calculus* : since like 90% of of physics is just multivariable vector calculus. *Matrices* are also useful, though typically only if you're working in the nittygritty parts of an engine. And this last one bridges the gap between maths and computer science, but it's been sooo useful to me in hindsight, and i rarely hear anyone ever talk about it: the very badly named topic of *Functional Programming* . A functional programming or operations research course will basically teach you how to take all of the maths theory you just learned and actually turn it into useful computer code.

I did my undergrad degree in maths, so I've been delighted to learn through game dev that a bunch of the stuff that I learned there finally has a direct use for me! Although, I have to say, when I found the quaternion function I was initially disapointed that the unity function basically does all the work for you, haha, then I remembered how difficult it would be to *not* have most of that be automated. So yeah I mostly agree that you need to know how to use quarternions, but not how they work necessarily, unless you're building your own game engine from scratch.

You missed that a game is basically a big Euler method integrator at its core. When you do things like "pos += velocity * dt" it's literally integration using Euler method.

@Madbook 11 месяцев назад

I agree that your example can certainly be described with euler integration! However, for the vast majority of beginner gamedevs, especially those who are relatively unfamiliar with maths as a whole, I don't think pointing them in the general direction of 'calculus' as a topic is optimal. I have seen far to many beginners get overwhelmed with differentiating/integrating/manipulating arbitrary equations that have no practical relevance to gamedev. As people progress to being more intermediate/advanced developers, framing some of these problems with calculus can certainly be useful - I just don't think it is needed for beginners. It's like telling them they need to learn how to operate a wrecking ball when all they really need is a hammer. I don't want this to come across as "I don't think calculus is important at all" either, and if it specifically interests an individual, then by all means study to your heart's content! It is fundamental to countless applications, and a very rich/interesting topic!

@@udyfrost6380 Well technically if you wanna implement accelleration you can just use Newton's motion equations, which are the double integral of a costant acceleration, meaning this is the real mathematical rule that governs the motion of a body with a constant acceleration, your update function would look like: "position += velocity*deltaTime + 0.5f*acceleration*(deltaTime^2); velocity += acceleration*deltaTime;" obviously you can make your acceleration vary in your program, as long as at each step you use the rule above with its current value. Also remember that a negative acceleration means that your body is either decelerating or accelerating in the opposite direction to the axis that the position specifies

@pirateskeleton7828 11 месяцев назад

With regards to Calculus, have to slightly disagree. While I don't find too much use for the limit or integration, the derivative is quite useful, especially given that it can be used to understand how to calculate stuff like velocity. My educational background is electrical engineering, specifically control system engineering. For my game project I end up applying quite a lot of concepts used in both control and signal processing systems. Stuff such as lag filters can be used to create smooth camera movement and eliminate high frequency noise. Concepts such as negative feedback loops, that have roots in differential equations, can be quite useful for making simulated automated systems that are meant to behave within your games physics environment. That being, said, I do agree with your other mathematical suggestions. I use trig in combination with vectors quite a lot.

@muddtheboss415 11 месяцев назад

I was gonna say the same thing, I've used calculus in pretty much all the projects I have worked on. Especially for velocity and acceleration calculations. Knowing the calculus behind these physics concepts can actually do a lot to make a game feel better.

@Kuroten01 3 года назад

I like this video, but you say calculus isn't needed then proceed to list around 4 items directly related to calculus (vector calculus: Quaternions, Dot Products, Cross products, Normalizations). For those unaware of what vector calculus is (normally called Calculus 3, or multivariable) "Vector calculus was developed from quaternion analysis by J. Willard Gibbs and Oliver Heaviside near the end of the 19th century, and most of the notation and terminology was established by Gibbs and Edwin Bidwell Wilson in their 1901 book, Vector Analysis. In the conventional form using cross products, vector calculus does not generalize to higher dimensions" So it directly deals with vectors, especially in 3D. If you are making a game in 3D and get intimidated by the daily math required, you are most likely lacking in calculus. So why the hell is knowing calculus essential to not only vectors but 3D math? Because of the tangent. Calculus teaches you how to use derivatives and manipulate slopes. Knowing this helps tremendously as the tangent is the most easily accessible 3D Vector. The essence of calculus is literally just finding the tangent. Let's take a vision cone system. A spotlight. Think to breathe of the wild guardians that use a spotlight to find the player. Note, I will simplify a bit as the math can get long. Naive approach. Let's just make a cone by creating a circle that gets larger as it approaches the ground. Concentric rings so to speak. We get the following vector: v = (cosine(angle), sin(angle)). v*d, where d is the distance from the ground. However, now move this cone to the X-axis and it squishes, the Y-axis and it breaks. For each axis, you need to figure out the appropriate ring...Because a circle in 2D is XY, a circle on the Y plane is XZ, a circle from the X plane is YZ. But what is a 2D circle projected onto 40% Y, 30%, X 15% Z ??? That is, as you travel on this 2D plane, you move in all 3 axes. A plane that is within all three axes, how do you create a circle then? More general approach: You get two vectors tangent to the plane, but perpendicular to each other and rotate them to form a circle. Oh boy, tangents, perpendicular, rotation, and speed, this is literally screaming derivatives and calculus. To do this you need the normal on the plane (how to do this, calc), get the tangent from that (how and why? Calculus), get the bitangent (how and why? Calculus), then do the following math: v = (tangent * cosine(angle) * radius) + (biTangent * sine(angle) * radius). (how and why? calculus) And now the guardians in BoTW can see link anywhere in 3D. And this leads to the final point, what is calculus? Well, calculus is all about approximations which is so important for computers. Things like floating-point precision are directly related to sequences and series. Along with that, calculus deals with analytical geometry, speed, physics...all of which are needed in a lot of games. There are so many examples of everyday effects in which knowing calculus is useful.

@Madbook 3 года назад

Hey, thanks for the feedback! Whilst I agree that calculus is incredibly useful, I still don't think it falls into the 'Maths for Beginner Gamedevs' category at the level of detail shown here. It would likely fall into 'Intermediate/Advanced Maths for Gamedevs', as calculus doesn't find it's way into most curriculums until the latter half of the education roadmap. To add to this though, most calculus problems that arise in gamedev are usually vastly simplified by the game engine being used. I agree that if you want to build your own engine, you'll need a very deep understanding of calculus - but for making a game, all of the mainstream engines will simplify out a ton of the complexity for you. Because of this, we will often use the practical outputs of calculus, without doing any calculus ourselves. Glad you liked the video on the whole though!

@@Madbook math is the language of science, which is physics. learning words without knowing the meaning behind them is not beneficial. as such, learning math without learning the underlying physical concepts will not make much good. even abstract mathematical concepts are tied to physical concepts. boolean algebra, in the contexts of computers, boils down to transistors being bi-state devices. my humble advice to programmers, especially to game developers, is to learn physics.

It's weird to me that you mentioned quaternions but not matrices. I feel like when discussing game maths I'd bring up things in this order: vectors > matrices > quaternions. Especially how vectors and quaternions can both be represented as matrices, it feels like a natural bridge to the quasi-4d weirdness of quaternions.

What are matrices used for in game development ? Any example ? I'm curious.

@@TealComet They're used alot in game engines to convert a 3d object to a 2d image which a player can see. This is the basic foundation of 3d rendering

Did you just spend three minutes of your video stating that you need to do basic arithmetic, hut not really because its automated for you? ... I hate to be rude mate, and I hope I dont come off that way, but you know the field of computer graphics and the field of artificial intelligence are both extremely calculus and linear algebra heavy, right? That starts with basic aritmetic, and oftentimes extends to abstract algebra. It's not "nice to know but not necessary".

Yep, I stand by what I said - keeping in mind that "Beginner Gamedevs" is in the title. You are correct that 'computer graphics and artificial intelligence are both extremely calculus and linear algebra heavy' - but: - Most people aren't developing graphics systems - they are trying to make games. They'll be using unity, unreal, godot...etc which handles the vast majority of this for you in most cases - Artificial intelligence in games is not the same as the 'field of AI'. People aren't needing to understand stochastic gradient descent to develop their games. The type of AI required for games is totally different and generally revolves around a more basic logic What you point out is valid, but I think I think that falls into more intermediate and advanced gamedev, and as a result is generally for more niche cases. That's just my perspective on it though, cheers for the feedback!
