[1.16.4] Get IChunk World / get current World for the overworld.

[MistyMarshes 0]

Hello. I was trying to get the World an IChunk is in, on version 1.16.4 (in the WorldCarver's carveRegion method).

 

Given that that seemed impossible, I'm trying now to do the next best thing for my particular case: get the current World for the OVERWORLD, but I couldn't figure that either.

 

Do you know how to do any of those?

 

Thanks for your help!

What's the context? If you only have an IChunk (not a Chunk) you are likely in world generation, which does not have a world yet.

Is that always the case? I'm in a WorldCarver's carveRegion method. I remember reading some 1.16 mod's code recently were they used the world there, but I don't remember what kind of pattern they used to make it available at that point.

 

I need it for a couple of reasons. I need to get its server -> ServerWorld -> DimensionSavedManager to start my WorldSavedData, I also want to use its getBiome, and probably a couple more methods. Do I need to look for alternatives?

Yup, thats world gen - i.e. no world access.

WorldSavedData cannot be accessed during world gen.

You can use IChunk#getBiomes to get biome information.

I see. I used to do it in 1.12 to load some world-dependent worldgen NBT data of my own. How would you go about it for 1.16.4? Do I need to implement my own file subsystem? Maybe capabilities? It is a considerable amount of data (not just some settings).

Why does your world gen depend on WorldSavedData? The thing is that world generation now happens on a threadpool, so there is no safe way to access the main game data structures like WorldSavedData.

Oh ok. It is a similar thing to how they used to load structures nbt files. Now that I think of it I should browse to see how they do it now. Do they regenerate structures on the fly every time, or save them to disk?

[diesieben07 7690]

I'm sure I understand your question.

That's ok, you made me think. Thank you for your time.

 

For completeness, my question was: how does vanilla load world-dependent data during worldgen? At least they used to do it to load the mineshafts NBT, and so on.

Mineshafts are not world-dependent. They generate the same in every world.
