Infinite room based generation

[sweet crag]

What is the easiest way to create custom dimensions of randomised room based generation.

[sweet crag]

More information if needed, game version 1.21.11, want to achieve making multiple custom dimensions built out of interlocking randomised rooms.

This gets asked pretty regularly. You can check this thread for starters, and then come back here for further clarity if needed

If you don't already know how to make custom structures, we have a guide here:

How do I fix my structures being all misaligned, and the holes in them?

[wet fossil]

your jigsaws are offset

wait a second, your structures don't have a center

this means there is no propper way to align jigsaws correctly

[sweet crag]

How do I add a centre?

[wispy drift]

Place a Jigsaw block in the middle (or wherever you want the game to think the center of your structure is), give it a Name, leave the rest of the fields the way they are, and then list that name as the start_jigsaw_name in the structure JSON

[sweet crag]

It's a 16x16 structure, would I put it on 1 of the 4 middle blocks or is a corner of the structure better

[wispy drift]

One of the middle blocks

[sweet crag]

it made it better, but there are still misalignments.

[wispy drift]

Yeah, unfortunately since chunks have even-sized borders, it's hard to get things to line up like this well. I do believe odd-sized rooms offer more consistency

[sweet crag]

how come the bars are not connecting to the wall? (jigsaw placing details into a structure)

[wispy drift]

Depending on exactly how they're being placed, they're not getting block updates

[sweet crag]

I have an upwards facing jigsaw connecting to a downwards facing jigsaw on both the base room and the bars.

[wispy drift]

And the bars are a structure piece?

[sweet crag]

seperate structure yes

[wispy drift]

Yeah that would be why then

[sweet crag]

there is a base room structure, and like 15 seperate bar structures

[wispy drift]

That doesn't produce a block update

[sweet crag]

is there a better way then?

[wispy drift]

If you want them to connect, I believe you can use a block column feature instead

Or you could save the structure with the desired connections present

And just make sure the vertical jigsaw blocks are oriented correctly and set to aligned

[sweet crag]

oh I see

that might work

[sweet crag]

why are my jigsaws not working? when placing it just leaves an air block where the jigsaw for the door should have placed.

[wispy drift]

There may not be enough space inside the parent structure for the child structure to fit without intersecting bounding boxes

[sweet crag]

That was the issue, just had to make parent slightly larger
