The cubies are called Corners, Edges, and Centers. Corners have 3 faces, Edges have 2, and Centers have 1. Another great video and I hope I can do something like this one day!

I usually have absolutely no idea what's going on, but here I am sat watching for an hour. Cause he makes it interesting!

Idea for a coding challenge: A Sudoku solver. Its probably not that hard, but I still want to see your approach. Greetings from Germany!

offset = (3 - 1) * len * 1/2 ... that's a long way of expressing len, LOL

[Kirkster]

I love the way you explain your code as you write it. It makes it so much easier to learn and understand. Thanks! Awesome work :)

20:53 Actually the middle layer is a move its called M :) You can do U perms, H perms, Z perms, or OLLs with M moves :)

You, good Sir, are a coding beast. My head did a full pi matrix transformation the entirety of this series. But I learned what I came here to learn which was coding the math and fundamental application of the three dimensional arrays for this project. Thank you so very much. I love your teaching style. Watching you make the same mistakes that we all make and your grace and humility in debugging on the fly is truly inspired my friend. You are the man. 🤜🤛

The best one yet. Can't wait to see the animation.

This code is so much cleaner than what I saw in the live stream. Very nice!

[ninjahyper]

I have got an amazing idea for getting to solve we can just add the key pressed values in a list and then when space is pressed we can just reverse that and it resolves itself

Every capital letter shares 7 bits with it's opposite case counterpart. If you can grab the binary ASCII data directly then FlipCase(char) should return char XOR

This was the day I was waiting for where cubing and coding combine;
Thanks!

Near the end of the video, you set up Sequence with a random set of 10 moves in a loop with Sequence += blah. Then you set up a second loop that takes Sequence and reverses it into NextMove. But this seems silly to me to have two loops. You could do this all in the first loop with these lines:

if (random) // rotate clockwise
Sequence += blah
NextMove = blah.UCase + NextMove
else // rotate counterclockwise
Sequence += blah.UCase
Nextmove = blah + NextMove

I learned a lot from you
Like how you do small steps and test them
And how you keep your mood high

5:10 Changing the i, j, k to x, y, z... That was awesome :)

"Guess what i can turn it...uh..wait" - Programming in one line.

[ttrouble]

I love you!! You inspire me everyday and i wish i could have your energy and positivity

[xheptc]

Started watching your videos, and they are amazing, I learned some things about coding, amazing challenges you do!

Another thing that you could use to perform 3d rotations is quaternions. They are 4d numbers designed specifically with the idea of performing rotations in 3d space and are relatively easy to pick up. 3B1B had an awesome video about them and I think it would be very interesting to see quaternions in action

[toadfrommariokart]

an easy way to give the correct number of faces:
for each cubie the number of faces is abs(x) + abs(y) + abs(z)
