Bottomless structures and floating villages in void? See here.

[linzexin022]

Hello Youmiel, I found a fabric mod that prevents structures (villages, ruined portals, etc) from being generated at the bottom of the world bottomlessly. Mabe you can find inspirations in codes of this mod. :) Here's the link: https://www.curseforge.com/minecraft/mc-mods/structure-floater-fabric

The bottomless structrues are related to worldgen bugs in Minecraft(MC-128659). It affects all structures that would match the terrain surface in world generation.

Unfortunately, it seems that Mojang don't have the ability or motivation to fix this bug. And datapacks are not as powerful as mods, due to the limited extensiblity in Minecraft's code.

So, at least in my opinion, this bug cannot be solved by a datapack. If someone does have a workaround to solve this issue, please tell me or pr to this repository. I would greatly appreciate it.

May be solved with this mod installed.

It seems that only mod could solve this issue. If anyone wants unbroken structure, just install this mod.
