Hey everyone! Hope you like the video :) This video is very introductory and doesn't go in depth with stuff like how perlin noise is generated or how it can be layered (in octaves) to give more interesting results. If you want to learn more about this sort of stuff I suggest you check out Sebastian Lague and Catlike Coding. They both have some great resources on this! There is a link in the description for that :) Stay awesome!
@Brackeys can you do a tutorial on worley noise? And maybe more noise types. I want to create more advanced terrain using more noise types and also want to create more advanced/cool textures
why i always dont understand what you saying.... for me CS is really hard to understand and i dont know why?? because i dont have probleme with javascript
Thank you Brackeys !!! Even though it's a long time since you poseted your last video. The channel still help me consistently. Best luck for you. Whatever now you're dealing with, you get our best hope.
Brackeys, my boi did it again! *Our voices are heard!* I salute you! Some people me including wanted this, feelsgoodman when it appears on my feed! Love the recent standalone tuts for deeper understanding of Unity3d.
I take this moment to thank to Asbjørn Thirslund for all of his videos. I learnt unity by watching your videos. I have been following you since "Make a game series", but I never actually shown my gratitude to you. So A biggg thank you to you for all your tutorials whether it be a small one or a complete series. Thanks to you I myself and many like me are game developers.
Thank you!!! This was all I needed to get my procedural world generation working for my game, this was the only thing I was having difficulty figuring out, thanks! :D
Wow i am so amazed at how professional your tutorials are let me just say thanks, thank you for these tutorials u go and make these for us and they are amazing i am truly thankfull
Instead of putting the generation into the update method, you could just put it into the OnDrawGizmos(). It then allows you to change the parameter. To reduce the calculation amount, you could add a dirty flag with setter on each parameter and only then reproduce a new noise texture.
For anyone who is in 2D and tried using the Sprite Renderer, you can't as it doesn't allow for textures due to overriding them with the texture from the sprite you are using . You have to use something like a quad (mesh filter) with a mesh renderer which will use the created texture directly and then set the material to unlit > texture like Brackeys does.
Q: "How to procedurally generate in unity?" Answer from Brackeys: "Call the Mathf.Perlin funktion!"... Honestly I was expecting a little more explanation of the math behind this rather than just showing one specific usecase of the perlin noise :(
I was hoping to learn more about how Perlin noise is actually calculated but hey still got the desired result. If you want procedual generation tutorials search catlikecoding's website.
I totally get your point and looking over it again I definitely think this video could use a more theoretical approach to how perlin noise is generated. That being said this video was meant more as a starting point for beginners who want to try doing some procedural stuff and so I didn't want to overwhelm with information :) If you want to know more about the math behind what's going on I've linked two great resources in the description :D
If you're using Universal Render Pipeline (URP/LWRP), instead of `renderer.material.mainTexture = texture;` set it instead with `renderer.material.SetTexture("_BaseMap", texture);`
muchas gracias, por todos tus tutoriales, este tipo de técnica fue usada para realizar la generación de terrenos en minecraft, seria genial que hicieras un ejemplo de como hacer un juego tipo minecraft, saludos desde Perú
Thus could anyone tell me how the Mathy.perlin work actually? I wanna to use perlinNoise in my own fragment, but what I can get is just Position and texture, I `d to achieve the perlin by my own function..........
Hey, I imagine you fixed it by now if you kept at it but for other people that see this, make sure your Math.PerlinNoise() is taking in floats for the arguments. If they are integers the returned float from the perlinNoise function will always be the same resulting in a flat surface on a mesh or the same color on a texture and whatnot.
If I understand correctly, you have an array of strings, maybe keywords?, and you want to find out if a given string, s, contains at least 1 instance of a word in the array. E.g.: string[] keywords = new string[4]{'up', 'down',' left',' right'}; string s = "This is probably some input from the user. Something like move left"; string[] delimiters = new string[]{" "}; // These are what will be used to define a "word" in your string. Here, a word is something separated by spaces string[] wordsInString = s.Split(delimiters, StringSplitOptions.RemoveEmptyEntries); // see msdn.microsoft.com/en-us/library/tabh47cf(v=vs.110).aspx for more info. for(int i = 0; i < wordsInString.Length; i++) { if(keywords.Contains(wordsInString[i]){ HandleKeywordEntered(wordsInString[i]); } } And you might have dictionary mapping strings to actions.
suppose that you havce an array of string named Array_Of_String , and you have the string named My_String , loop throughe ach elemnent (name it Word ) in the Array_Of_String and inside that loop check if My_String. == Word do something else do something else
you can do it like this : string[] Array_Of_Strings = new string[2]{"TH-cam","Brackeys"}; string my_String = "Brackeys"; foreach(string word in Array_Of_Strings){ if(word == my_String) Console.WriteLine("the word " + word +" is equal to the string " + my_String); else Console.WriteLine("the word " + word +" is NOT equal to the string " + my_String); } so the output sounds like this : the word TH-cam is NOT equal to the string Brackeys the word Brackeys is equal to the string Brackeys
Your videos are incredible and they teach so many things. But I honestly had to check my player settings to make sure the video wasn't at X2. Slow doooooooown.
Perfect Mate, i'm really interested in procedural animation, i can't find any useful explanation on this, if you can make a little exemple on this that will be amazing. keep it up !
wow it's insane to think that since minecraft uses perlin noise all the worlds i've been in are all the same world but in a way it's just picking random spots to set at (0,0,0) xy and z i know understand why in 5th grade they told us minecraft was larger than galaxies in 5th grade i thought how can it be larger than galaxies if it's just creating multiple random worlds wouldn't it be infinite but no apparently it's just different points in that insanely huge galaxy sized planet.
Hey Brackeys, so my Animation course is going well so far :) We're currently using Maya so if you need any assets I'd be happy to help! Purely for practice as I've only been using it for 3 months now :)
sorry for the late reply but mine did the same thing, but I just did this i put this at the very start: using System.Collections; using System.Collections.Generic; just above the using unity tag. he deletes it but for me it worked when i did that
I would suggest against using perlin noise and implement simplex noise instead, not only does it support n dimensions, it takes way less computing time.
How would I actually apply this concept as I don't want my game to be based off of a texture. Can you make a video with an example of actually applying this principle for procedural generation.
He said he would do this next week. I advise you to look at Sebastian Lague's Procedural Landmass Generation series (as well as his Intro into Game Dev, if you're new to unity)
Have a world generator script that implements perlin noise, though I would recommend implementing simplex instead. Then if you're making say a 2D game, iterate through every coordinate you want to generate a tile for (n chunks around the camera to save processing time) and calculate the value (density) of said tiles with simplex/perlin noise, then apply which ever rules you prefer and create a corresponding object there or use from pool to prevent major lagspikes. For more complex world generation you can do multiple passes eg. first pass adding basic features like height of the terrain which determines if there is deepwater,water,sand,grass, rock, snow you name it. second pass to determine where trees and other foliage are located and so on. For roads and caves, you should look into perlin worms algorithm or similar. I am not very good at explaining things, but I hope you got something out of this regardless. If you have any questions feel free to ask. PS. perlin noise doesn't work well with integers so you can just add a offset of .n to get desired result.
oke so i have a thing that triggered my (OH NO NO NO NO ) senses if u set the color of a thing in an rgb color scheme you will always get a solid color on brick no differences so run 3 perlin noise function as he did and then set each one to a color value i dont know what r they called exactly btw thats what worked for me so yeah pls brakey pin a comment clarifying this issue or help me understand the topic please ur a god pls ur the best at making games pls pls pls
Hi! I have a question about xCoord and yCoord. When I just try convert int x value from loop to float I get a result like 0,4652731; How it works? for example: loop index x = 1; then xCoord = (float)x; is equal 0,4652731, and next interesting point is...when I divide x to width (width = 256), then xCoord is equal 1. Thanks for help :)

Great video, been waiting for this for a long time
Script:

this makes it look complicated

Love your math involved tutorials
Your Face Lighting is Perfect.
Remember to move the renderer initialization into the start method!
Can't wait for the terrain generation video. Keep it up
when u write the code and it works in the first go
That moment is heaven
YUP.
Everytime I am realllllly happy it worked and **dies of dopamine overdose cause it worked first time**
I don't even make games and yet I find this entertaining
oh wow, that was fast, thanks and keep it up with the awesome work!
Q: "How to procedurally generate in unity?"
Answer from Brackeys: "Call the Mathf.Perlin funktion!"...
Honestly I was expecting a little more explanation of the math behind this rather than just showing one specific usecase of the perlin noise :(
A good explanation would probably be this:
Take pixel noise, scale it by a number (like 5) and then blur it
Look at Sebastian Lague's procedural landmass generation series.
I was hoping to learn more about how Perlin noise is actually calculated but hey still got the desired result. If you want procedual generation tutorials search catlikecoding's website.
en.wikipedia.org/wiki/Perlin_noise
You're welcome

Just learned about perlin noise a couple months ago in my graphics module.
Awesome! Looking forward to terrain generation.
love it! more please.
Awesome Video as always =) Thanks for your help
Damn! You should be a professor at some university. You explain things with great ease. :P
Спасибо! Хоть я из Украины, но с радостью смотрю Ваш канал! :)
Holy shit thanks so much! I've been struggling because I did not offset nor scale the value! Thanks
Simply just helpful
This guy is the happiest male I have ever seen
Thanx alot man , please do the procedural generation with terrain soon 😄
keep the awesome work coming 😍😘
If you're using Universal Render Pipeline (URP/LWRP), instead of `renderer.material.mainTexture = texture;` set it instead with `renderer.material.SetTexture("_BaseMap", texture);`
my god i can generate terrain
thanks man, you are a unity God
muchas gracias, por todos tus tutoriales, este tipo de técnica fue usada para realizar la generación de terrenos en minecraft, seria genial que hicieras un ejemplo de como hacer un juego tipo minecraft, saludos desde Perú
Thank you very much.
Can you show how octaves and some other parameters in perlin/simplex noise work in part 2?
Look at Sebastian Lague's procedural landmass generation series.
Can you make the texture more sharp?
we all miss you :(
Man, that's interesting.🤩🤩🤩
Omg! i was just working on procedural map generation in my game, and i saw the notification just next to my code and i'm here like LOL! XD
I remember the good old times when he was still here
*becomes sad again*
Hey Brakeys, could you please make a video on Enemy AI. Your old video on the subject doesn't work too well this the latest version of Unity.
Thanks
Great job.
Dam these Pixel are lit fam xD 6:19, Loved the tutorial tho great job :D
come back please. I am learning ECS and I need your voice to guide me.
FINALLY
Thank you
Idk if somebody wants but here is another SCRIPT:
using UnityEngine;
public class PerlinNoise : MonoBehaviour
{
public float scale = 1f;
public float speed = 1f;
public float offsetX = 0f;
public float offsetY = 0f;
private float noiseSeed;
private void Start()
{
noiseSeed = Random.Range(0f, 100f);
}
private void Update()
{
offsetX += Time.deltaTime * speed;
offsetY += Time.deltaTime * speed;
Vector2 offset = new Vector2(offsetX, offsetY);
float x = transform.position.x / scale + offset.x + noiseSeed;
float y = transform.position.y / scale + offset.y + noiseSeed;
float noiseValue = Mathf.PerlinNoise(x, y);
transform.localScale = new Vector3(1f, noiseValue, 1f);
}
}
Write if this script has any ERRORS!!
this script also is abt Perlin Noise!
Thus could anyone tell me how the Mathy.perlin work actually? I wanna to use perlinNoise in my own fragment, but what I can get is just Position and texture, I `d to achieve the perlin by my own function..........
I did everything exactly as shown... All I have is an incredibly brightly white square... No errors or anything... Just not doing anything...
Hey, I imagine you fixed it by now if you kept at it but for other people that see this, make sure your Math.PerlinNoise() is taking in floats for the arguments.

@@chriskoehl184 Thank you. I did manage to fix it. It took me way too long to figure it out though...
Hey guys I have a c# question (not the c# in unity) so how do I check if a string contains any word in an array?
you want to know if your string belongs to an array or if the word contain at least one element from your array ?
If I understand correctly, you have an array of strings, maybe keywords?, and you want to find out if a given string, s, contains at least 1 instance of a word in the array.
E.g.:
string[] keywords = new string[4]{'up', 'down',' left',' right'};
string s = "This is probably some input from the user. Something like move left";
string[] delimiters = new string[]{" "}; // These are what will be used to define a "word" in your string. Here, a word is something separated by spaces
string[] wordsInString = s.Split(delimiters, StringSplitOptions.RemoveEmptyEntries); // see msdn.microsoft.com/en-us/library/tabh47cf(v=vs.110).aspx for more info.
for(int i = 0; i < wordsInString.Length; i++)
{
if(keywords.Contains(wordsInString[i]){
HandleKeywordEntered(wordsInString[i]);
}
}
And you might have dictionary mapping strings to actions.
If(array.Contains(myWord))
or foreach(string s in array ) {
if(s == myWord )
{
Print...
}
}
suppose that you havce an array of string named Array_Of_String , and you have the string named My_String , loop throughe ach elemnent (name it Word ) in the Array_Of_String and inside that loop check if My_String. == Word do something else do something else
you can do it like this :
string[] Array_Of_Strings = new string[2]{"TH-cam","Brackeys"};
string my_String = "Brackeys";
foreach(string word in Array_Of_Strings){
if(word == my_String)
Console.WriteLine("the word " + word +" is equal to the string " + my_String);
else Console.WriteLine("the word " + word +" is NOT equal to the string " + my_String);
}
so the output sounds like this :
the word TH-cam is NOT equal to the string Brackeys
the word Brackeys is equal to the string Brackeys
Thank you!
Your videos are incredible and they teach so many things. But I honestly had to check my player settings to make sure the video wasn't at X2.
Slow doooooooown.
Thanks for the video! Any reason not to use sharedMaterial on that renderer vs. material which will create garbage / duplicate the material?
Perlin noise does not repeat at integer coordinates. Perlin noise is defined to be 0 at integer coordinates.
Have you ever considered releasing a commercial game?
Perfect Mate,
i'm really interested in procedural animation, i can't find any useful explanation on this,

it keeps saying that not all paths return a value when it comes to int x, int y

For more complex world generation you can do multiple passes eg. first pass adding basic features like height of the terrain which determines if there is deepwater,water,sand,grass, rock, snow you name it. second pass to determine where trees and other foliage are located and so on.
For roads and caves, you should look into perlin worms algorithm or similar.
I am not very good at explaining things, but I hope you got something out of this regardless. If you have any questions feel free to ask.
PS. perlin noise doesn't work well with integers so you can just add a offset of .n to get desired result.

oke so i have a thing that triggered my (OH NO NO NO NO ) senses if u set the color of a thing in an rgb color scheme you will always get a solid color on brick no differences so run 3 perlin noise function as he did and then set each one to a color value i dont know what r they called exactly btw thats what worked for me so yeah pls brakey pin a comment clarifying this issue or help me understand the topic please ur a god pls ur the best at making games pls pls pls
thank you¬
pls make a video on touch input for touchscreen devices
Thank you sir :) Still valid :)
Perfect. I am creating clouds.
how can i save the texture on my project for future use ?
Step 2: turning the noise into a height map.
can you show how to make player jump (BTW i love your vids)
9:50 just make a int called seed instead of making it individual for x and y
You could use the var keyword instead of typing the variable type all the time. It makes the code much easier to read. Great vid!
Hello, can i make a specific type of noise when i can declare when i need the max or min values?
How efficient is it in mobile?
Also, can we use Perlin noise in a shader?

then xCoord = (float)x; is equal 0,4652731, and next interesting point is...when I divide x to width (width = 256), then xCoord is equal 1.
