Large, random structure generation

[HighFox]

So I want to create an underground structure that is randomly generated with multiple different templates that all connect, like a mineshaft or a stronghold. I've tried looking at the vanilla code for structures like this that are already in the game, however I can't get my head around how it all works or how I would go about implementing similar techniques. Does anyone know roughly how it works and how I could generate a structure like this, or if there are any examples somewhere I can look at?

Thanks in advance!

Its complicated.

You need a structure, structure start, and structure pieces.

Its registered like anything else.

Thanks Draco18s!

Your code is a lot smaller than that of Mineshafts, Strongholds etc. so it should help me a lot.

It also doesn't do much.

That's fine! Anything helps haha.

It shows me how to generate multiple components which is super helpful.
