I'm back with a new video! Thank you all so much for your support watching these videos, you reinvigorated my love for making videos! :) More video's will follow: we're back in action!

4:26 Perfectly synced villager “hmm?”

“In the future, entertainment will be procedurally generated”

"you use a random seed generator to randomly select the number in a sequence" "ok so how do you randomly generate a seed?" random number generator used to randomly generate a seed: *sweating*

I was calling my dungeon generation procedural, but it was actually random. Thanks for enlightening me!

wow, now I understand how no man's sky has certain bugs with regards to base building and terrain interaction. Somtimes you would build a base , where you've carved out terrain and such and then next time you loaded the game the terrain has seemingly returned except it's now inside your base. It must have something to do with the order in which the base modules and terrain edits are loaded in whilst the map is being generated. Shame they've never managed to fix it though.

Welp. That worked. *_Throws the Necronomicon away_ * Another channel back from the dead.

digi you barely made the January 2020 deadline! really glad to see a video after 2 years

i was avoiding this video, dismissing it as another one of those mundane tutorials on youtube that takes forever to explain a simple point. But i was wrong. You, my beautiful man, Have got me hooked on this content. Seeing as i always wanted to try and become a programmer or developer of sorts in my future, This is fascinating on how all of this actually works! Keep up the amazing work and i wish you only the best!

I clicked so fast just so KZfaq could get off its ass and hopefully recommend this.

Recently found the channel and was super happy, until I thought it was abandoned. Seriously, your channel explains this in the most comprehensive way for people who have no clue. Also loved the critique videos, because it doesn't just gloss over what one feels as a player, but actually breaks it down into classic design theory. Keep it coming!

Oh all the visualizations are so great! Thank you so much!!

Super cool to see this channel revival, The content here is top notch my dude!

I'm glad there aren't any people trying to "debunk" this video like the terraria one. That got really annoying to me, and I'm glad you stuck through it!

wtf man, its been 2 years, i subbed a few months ago and loved your explanation of portal and terraria. i was gutted to see that you havnt uploaded in 2 whole years! thought you died, im glad youre back, im looking forward to loads more content from you!

You returned! I discovered your channel by your portal video, keep it up man!

I've been trying to understand Procedural Generation for so long now, and you managed to explain it perfectly in one entertaining 13 minute video. I'm absolutely stunned. THANK YOU!

12:35 change da world my final message. Goodb ye

Please do not stop creating these videos. You help and motivate a lot of people. I am new to programming, just started with C#, and the motivation that I got from these videos is insane. The fact that you can create infinite universes and all that good stuff is driving me crazy. I really just want to say *thank you* , thanks *a lot*

I remember back in the '80s, after wondering if RNG was related to the system clock, I wrote a small BASIC program to display a random number upon boot of the system. The system (an Acorn BBC Model B microcomputer) did not have a real-time, battery-backed clock, so only used the system bus clock to time its operations, meaning that the bus clock started from a fixed state each time the computer was turned on. Unsurprisingly now, the program produced an identical number every time it was auto-run whenever the computer was cold-booted. From that point on, I never accepted the idea of true randomness in computing.

I saw your video on terraria in my recommendations today, watched it and really liked it. The comments said this was a dead channel, so I got a bit bummed out then saw that you had a video posted 6 days ago. After a two year gap...

I’m glad to see more content from this channel; you somehow manage to always make a video on some game-development-related topic that I’ve wondered about for a while :)

Fantastic video! I’m glad I discovered your channel a month ago instead of 2 years ago!

I learned so much from your video. As a math teacher, I can appreciate much of what you are talking about. My mind is blown. I understand this in a much deeper way. My kids will love this!! Thank you!

It's great to see you back and making videos, they are so fun and interesting and I learn so much when I watch them. They are very inspiring and give me the push to keep going. Thank you for taking to time to make them, they are appreciated so much!

A really high quality of content, loved the videos and the way you explain them. You are really great at breaking down complex and technical subjects and teaching them part by part! Keep up the good work!

Always wanted to learn a bit about procedural generation but never really committed to it. However, I am very interested now! Thanks Digi!

I just want to say, the production value of your videos is way higher than what kind of recognition you are getting. This content is some of the best that I've ever seen when it comes to explaining complicated concepts in games. You do an amazing job of simplifying the content just enough so that it is understandable, but not boring to watch. You deserve so much more than what you're getting and, if you stay motivated to keep putting this content out, you are definitely going to find success.

Not gonna lie, this poped up in my recommended. Many comments saying you haven’t been uploading. Idc, you’re part of my major and dream job, I’m learning here more than my CSIT classes I get in college. I subscribed and hope you upload more. This is a great channel, I want to know more please!

Welcome back! I'm so glad you decided to continue.

Please keep putting out videos! I've just discovered your channel, and though I've only watched the most recent stuff, it's all been super interesting!

Your videos always fascinate me and I always learn something new! Thank you so much and keep up the great work😁

Ah, Minecraft and Terraria, the perfect pair of games for explaining procedural generation.

Wow, a 2 year break but you actually uploaded the next episode as if no time had passed at all! Great work, this is a great explantation of technical information in a less technical way. Much easier to understand.

What a great video! This answered so many questions for me. Looking forward to more videos from you in the future.

Randomly suggested your videos on Portal and Terraria and watched this one, didn't realise until the end that you made the Terraria video 2 years ago. Cool videos, keep it up. New subscriber.

enjoyed your way of presenting all the info! good job!

9:44 "Argumented reality sandbox" - This looks nice. Aside from that: Nice video, thank you for producing and sharing. : )

the way you explain all the way from the interpretation of "noise = annoying sounds" to complex 3D cave systems is amazing! Your visual demonstrations are on point

I've had some knowledge of how this was done...I love open world and procedurally generated games - but I never watched a video where anyone attempted to explain it with a bit more digestible detail. Thanks!

I only subscribed a few weeks ago after watching your old videos, I thought you’d disappeared for good. I’m glad you’re back, loved the video!

Thank you for this. I absolutely love preceduaraly generated world's and this video was great and easy to follow. I am just starting to learn how to code, so many there will be a procedurally generated game in my future

I have been thinking about the questions you mentioned in the video. Thank you for answering them!

I watched this video while wearing a pickle rick t shirt. The first second was shocking. Randomness just got squared!

Thanks for coming back with more info on procedual generation! :)

Keep making videos man! After watching your portal video and realizing the youtube algorithm brought traction to your channel after you gave up on it. So glad to see new videos form you. You're doing an excellent job with the editing and explaining complicated topics. Definitely make something of this opportunity. Just to let you know i don't usually comment but for the sake of you keep posting i commented, liked and subscribed!

The quality of this video is so high. You are great at explaining things and great at keeping the video interesting.

The potential of this channel is huge, the content is captivating. Here's hoping for some more regular videos!

I love your vids so much! Im very happy that you are back, because i found your channel while you where away liveing life. Please dont stop makeing content. 🤠

As always, the quality of your content is above all expectations! Thank you for your videos, btw I am about to finish my first game)

great and easy to understand explanations. love it!

great video ! keep posting videos like this, you explain everything really clearly and interesting

I love your videos! They're so informative! Geweldig!

Amazing content, id love for some more of this!

as a very bad coder, things like this just fascinate me. its just awe-inspiring how a large series of numbers and letters can create entire worlds!

Really cool video, with some awesome visuals to match. I'd like to further stress the importance of things like perlin noise. You can't have a sequence that's the same every time but requires starting at the beginning to calculate it. Pi is actually a good example of this. While it's random and goes on forever, you can't just pick a digit to start at without calculating the digits prior. Perlin noise lets you jump to any position and get it's value without caring about the values around it. This is key when developing a procedural generated world. Water running down a mountain might pool somewhere as a lake, but when a player finds this lake you can't have it figuring out where the water starts first to determine said lake. It's just not performant. Of course the scale of what you're trying to generate will determine how important this is. Spawning flowers around a tree isn't out of the question, but spawning a tree based on it's proximity to other trees might get you into trouble quickly.

I LOVE YOUR CONTENT AND IM SO HAPPY THAT YOU REBOOTED THIS CHANNEL!!! KEEP UP THE GOOD WORK PLZZZ

Excellent! Thank you for making this easy to understand, so good!

This is amazing! Thank you for this introduction to procedural generation knowledge!

Hey man, really love your videos, nice to have you back :)

This is one of the most magnificent and awesome explained tutorials ever, dude you are great. Many thanks.

Two years later, this video is still fantastic. Thanks a bunch, I look forward to the rest of your content.

glad you're back, and amazing video btw

Please keeping creating videos. You are a great educator honestly.

Your content is excelent! Your presentation makes it interesting for experienced and new game developers alike

Man, your videos are so great!!!!!!!!! big support from France!

Hi! Quality content here, thank you for talking about VR sandbox, I didn't know about it at all, it looks insane

He's back!! Awesome video as usual, super helpful

It's nice to hear someone with technical knowledge talking about videogames. Good job and keep going

So glad you're back! Your videos are awesome.

Another great video! Glad to see you’re back.

For the seed to create your Perlin texture, add to the system time the square root of the product of the cpu fan speed and gpu fan speed (as integer,neither dismissing decimals or dismissing the coma). For the displacement strength of white pixels, you use the full degrees of the cpu temperature plus the decimals*10 of the gpu temperature and for the displacement strength of black pixels use the full degrees of the gpu temperature plus the decimal*10 of the cpu temperature.

I've been looking for something like this for a while! Thank you!

Glad to see you uploading!

Broo your channel it is amazing and your way to explain it is perfect. Please keep making videos

Great video! Also, I'm glad you're back :D

man i am so glad that you decided to upload more let me tell you i am really glad

Dude, I'm so glad you came back and just didn't stop making these videos

This video is amazing and very instructive, thank you a lot !

Thanks for being back!!

Gooood looord, duuude. I was searching for this explanations of procedural generation for my world generator. Thank you so much!

I’ve been studying programming and game developing for a year and never heard of perlin noise before. Because of your video, I’ve learnt a new concept and I’m going to study how to use them now!

Finally! A good video that also explains how caves can efficiently be generated. Thank you 🙏🏻

Oh my, you're back! I only found your channel after it was too late, luckily you came back :)

It's been a while since I watched the previous video about terraria and in the video you said you would talk about this topic, if I'm not mistaken, but then I saw that there were no more videos for 2 years. Today I just got this in my recommended videos. Nice surprise

Awesome video, thanks so much for this video!

Thanks for coming back! Just after I discovered your channel, I noticed you've been gone for 3 years. But I fortunately saw your comment on the last video and here we are! Congratulations! Keep uploading, your content is amazing!

me and my friends are trying to build a game and your vids give great advice. thank you.

Thanks for sharing your knowledge!

This channel is pure gold. Do not disappear please!

I learned about a new noise today, thanks to you. "Ridged fractal noise" and welcome back, community needs you :)

Thank you for this! first 3 minutes and I've already learnt something new

Loved the video, very informative.

Wellcome back :) This video was awersome

Someone know this feeling when you have an idea for a simple game that you try to ignore so hard but everywhere in your life things pop up and remind you of it? So annoying.

i Have really Learned lot from your video thank you very very much Just found you and Subscribed Especially the Noise and the saving of the world using seed number with the same formula

This was great! Welcome back!

Great video. Would love to see more videos!

Finally, the time has come.

It should be noted that Perlin noise is only one type of noise. There is also random noise, simplex noise, cellular noise, veronoi noise, blue noise and more. Oftentimes, especially when working on the GPU, it is advantageous to use different noise that is less expensive. Also, the using of 'multiple passes' to layer noise with different weights and scales is called fractal Brownian motion, or fBm.
