Unity 3D chunks. How does it work?

I don't know how to program an infinite map (or chunks). (C # / Unity 3D)

I also watched YouTube but that's mostly just reprogramming Minecraft in Unity or something. So I ask you:

How do you program chunks with this Perlin noise script ().

(Please write the whole script for the chunks and whether I still have to do something, e.g. Add a component or something)

First about Perlin noise: Perlin noise is already pre-implemented in Unity. All you have to do is call it up. It generates a map that looks similar to a primitive Minecraft map. Something like this: (each color stands for a certain value between 0 and 1. You can have this returned to you by the Perlinnoise function and then use it as the height for blocks (in minecraft), for example)

And about the chunks:

It all depends on which game you want to play. THE universal script for chunks does not exist. Also, you can't just write a CHUNK script. You just have to build your whole game modularly so that it can be summarized in these chunks

And sorry for the late reply XD
