Hi, I'm not a game developer but I am learning all this concepts to apply on web front-end development and even shaders. I don't understand how this is here for free, it is amazing. Thank you for this great great job.

[atxdank]

knowledge should be free! thank you for sharing <3

i popped in out the blue and stayed for the clever stuff that is beyond me, yet somehow makes sense to me, thats gonna say more about you than me, thank you for the refreshing info i wll probably never use & yet i had a window into somerthing fasinating. thank you

I wish there were some notes or a book to go along with these lectures. That would very helpful. Thanks for these lectures :)

At 14:22 or before you mentioned the horizontal and vertical components of a vector to be [cos(theta), sin(theta)] but i think you actually need the magnitude or force so it would be [f * cos(theta), f*sin(theta)] because cos(theta) =x/r => r*cos(theta)= x etc.

I missed this by a short bit! Thanks for putting in all this work!

autoplay was on when I left for work. This was on when i got home. I don't understand a single thing... other than you give lectures and have lead esoteric discussions and I am probably in love....

[MrRaschke]

Hey, is there a link for PSD file of all the drawings you did? Would love to have an overview of everything! Great job with the lectures!

[engrenage]

subject seemed cool at first, but then I saw no mention of quaternions so I figured I do something else.

[realcygnus]

Great stuff as always ! Where is that spline vid you refer to ?

I went to sleep listening to MLM debunking* and woke up to someone teaching maths. I feel like the universe is trying to tell me something.

*For anyone unaware, MLM = Multi-Level Marketing. I'm not watching people debunk men who love men.

[nobody-thro]

idk why im watching this while im in fifth grade

[bobmichael]

how do you write so pretty in photoshop?

[NickChira]

Lol the algorithm gave me this after watching gacha game videos. Thanks for giving me PTSD of my engineering degree days

I'm kind of curious how does transform.position += Vector3 works if it's a struct? Shouldn't you get it to a temp var first and set it back after?

Also Vector2 = Vector3 and Vector3 = Vector2 assignment, as far as I remember Unity didn't like one of these... 🤔

[therealmysticmask]

Thanks! just gave the kitty a bath and only got one scratch. My daughter is also Freyja and I.m a math teacher

[MrRagnarxx]

i don't care about this, why did this autoplay again

Hello, I started publishing videos about health and sedentary lifestyle
