world generation mechanics

[Somecat]

I am C# coder and i assemblin' my small game with simillar world generator.
I made a test assemble of nice Perlin noice generator, but stuck in one trouble. It generates easy one chunk (as one in spoiler) but always randomly. Then some event happens, another one chunk must be generated lefthand of this one and connects to.

Spoiler:

I thinked that if mechanic simillar someone can tell me how same realised in Factorio. I need not code but idea.

I may sound brazenly, but reason is my bad english, sorry.

Well. I googled hard a Perlin noice topic and solved my problem. Can any moderator delete this thread please?

We don't delete topics, if there is no good reason, cause others might have the same question.

But there is no answer just question :\
I see there no useful information. Nonsence.

Someone who read the question might have the idea to PM you...

What I mean is: Don't think, that non-information is useless.

Edit: Gppgle earns millions of $ per day with such information...

You can always add your answer to this thread, so others don't have to google hard for it.
