Man. I just woke up to this playing and I was having a lucid dream where someone was taking me hostage and I had to give an answer to some number riddle. Freaky.
Brother this is so funny wtf, i woke up 3 hours ago to this where i also had a lucid dream but i was chased by my girlfriend bcs i was cheating her with the peppa's pig dad running across the square garden (ive never been in the usa xd )
WHY DO I ALWAYS WAKE UP TO THIS! I AM NOT A GAME DEVELOPLER! I WOKE UP TO THIS MANY TIMES! WHY DOES RUclips THINK FOR SOME REASON I WANT TO WATCH THIS OVER AND OVER AGAIN!!!! WHY!!!!

"a lot of people forget math" Thank you, you are a lifesaver. I am someone from a different field who used to work in web development for 2 years, but I am very passionate about Unity programming and transitioning into it. I have forgotten most of my math, but thanks to this series of yours, I hope it will help me in the learning and self-development process.
Wow, this video is absolutely amazing! Freya's method of explaining math concepts for game development is truly brilliant. The way she presents the material is so clear, concise, and easy to understand. The examples and visuals used throughout the video were incredibly helpful in solidifying my understanding of the subject matter. I can't thank you enough for sharing this valuable resource, Freya. You are a gifted educator, and I look forward to watching more of your videos in the future. Keep up the fantastic work!
In case someone is struggling with the fact that the vector a-b gives you the vector from b to a and not the other way around, maybe this helps: To get from b to a, you can first subtract b (i.e. -b) to get back to zero and then add a (i.e. +a). So the vector from b to a can be written as -b+a and since we're allowed to flip the numbers (or vectors) around when doing addition, this is the same as a+(-b) or simply a-b.
@@UNABRIDGED_SCIENCE You have so many issues that I don't even know where to start. Seek some help. Maybe start with your social skills, then follow up with English language classes. Really. Seek some help.

If my math teachers in middle/high school were lovely people who love cats, I would be a math genius by now I never developed anything, but suddenly had an idea that would make a great game for my final project in college, so I decided to take in the challenge. I’m sure your content will literally save my life. I haven’t even watched an hour of it yet and I already love your way of teaching, I can’t believe you’re putting all this out for free!

@1:15:55 - just now starting to get back into a little bit of enough time to do a math refresher again (always needed). This part clicked with me in a different way (vector addition). I know it's intuitive to some, but not to those outside of math, that it's simply taking one of the two points and "offseting" it by the amount of the other. A lot in math and gaming know addition/subtraction are the same as offsetting, but not all think of it that way.
To draw a perfectly straight line in photoshop in any direction. To draw a perfect horizontal or vertical you can hold shift and draw horizontal or vertical. To draw in any other angle, First you must put a dot in the starting point the hold down shift and place a dot at the end point.

@@invaderzip7356 I mean the tablet works fine, it's just that it takes pen pressure into account for the start/end of the line, and unless I jam the pen into the tablet for 1 frame at the end, the line won't have full opacity
Hi Freya! Just stopping by quickly (before even watching the VOD) to say thank you for doing this series! We really appreciate you and what you're doing... Even old guys like me who need to refresh our failing memories now and then. 😅Please keep up the good work. 😊
I'm 61 with extensive background in 3D, simulation, and so forth, but trying to get my mind around the actual guts of interactivity, eg. programming/scripting and MATH! Thank you for these videos.
Hey megabosscat Freya, I noticed after the 1hr ish mark you mentioned that imaginary numbers are not important to game dev, but... Quaternions :)) I get what you are inferring i think, which is that it is unlikely any engine user will ever customise a quaternion implementation themselves and therefore can simlpy just use them when calling to some in-engine wrapper like Quaternion.Something(). But from a mathy POV [which you said you were coming from I think], its pretty important to represent orientations and rotations in game math, especially when aiming not to incur things like rotational edge cases such as gimble lock [when using Euler math to solve for O and R]. Your great by the way, and I'm certainly not trying to throw any shade/or corrective attitude at yuo (i've learned so so much from your content), but I think it might be fairer to say something like "they sit lower down the chain in game math where a dev might not need to know much about the inner workings, but be satisified the math has been proven so it can be used without worry of the constraints that come with using Euler method. ?? i dunno, am I wrong here, or did I misinterpret this part of this absolutely amazing long form lecture?! Thanks for all your super hard work to deliver this stuff, I literally love catching up on your latest videos. [Also, if you have time, let me know if I did misinterpret the whole imaginary numbers section on whether one should at least know about imaginary nums] 🥲
most people who use quaternions never actually understand or unravel the inner workings, and I would even go as far as to say, most people making engines also don't really have to learn how quaternions work, you can just copy/paste code and trust the math and you'll be fine. so yeah, this is why I don't consider it important. it's interesting though!
@@acegikmo I'm actually using imaginary numbers right now for the solution of the signed distance field of a quadratic Bezier curve in a ray marched shader.
Are there any differences between this videos and the ones you did 1 year ago? Is there more content? I'm doing a videogame master and I would be interested in learning more about math because I really suck hah. Should I watch this new one from 2022 or the old one? Thanks in advance!
the content is about the same, but the old ones are edited to remove pauses and whatnot, so they are a little easier to watch! The end of this course will have some new things though
@@acegikmo just to confirm is this the type of math thst is useful and relevant to people who want to get into designing and developing video games?? Thanks for sharing freely for those who can't afford classes now if so!
Hi Freya , cant thank enough for these videos -- i am just about to start watching this series , should i watch Math For Game Devs (2020) before this ?
I would argue , like calculus, imaginary numbers are used to very frequently. If you're designing your own physics engine. But especially imaginary numbers are used a lot by people. It's just abstracted into functions.
Lol at RUclips UX with not being able to find the superchats. Idk why but RUclips has a really bad UX in the app and I guess on desktop with live chat too.
you almost always have your headset on, is it a habit just to casual have it on or do you actually have it playing something? I just like to have it casually myself...

maybe this is principle of change any children's transform space to any of transform space you want ?
Think of it as Final minus Initial, it’s a common concept in math and science and can be applied generally.
Also delta x = xf - xi. That is final minus initial.

Um actually the vector at 1:32:20 would be a-b not b-a. For length direction doesn't matter, but b-a would point the other way.
