minecraft server new world?

It probably does take some sort of garbage as a seed value, but I dunno if the initial garbage dictates the entirety of the map.

If you walk in wide-enough a circle in an unexplored area, the place where you meet your starting point is likely to have weird artifacts, like a wall in the landscape. There is one of those right by Kingzjesterland (though I've nerfed it a little by digging around it).

I attached a screenshot. If there was a way to generate identical worlds from some seed value, wouldn't you think the world would anticipate the junctures better? Maybe this is an artifact of something else altogether, tho I dunno what it would be.

That said, I am pretty sure by importing the old world we can import blocks that are there right now, placed or generated, rather than some pristine virginal world.

Hmm... I admit of knowing almost nothing about Minecraft servers so I have no idea what exactly we can bring over or how.

But I dug around a bit and found this quote from reddit:

The complicated high level technical version is: First I generate a linearly interpolated 3d perlin noise offset along the y axis. I fill that in so that everything except the top x blocks is stone, then I do a second pass to add features like grass, trees, gravel, sand, caves and flowers. The world is generated in chunks of 16x16x128 blocks, based of pseudorandom seeds that are a mix of the level base seed and the chunk location in the world. This ensures that you always get the same terrain in an area regardless of what direction you traveled there from.

I don't know what that means exactly for randomness but from that it sounds like the straight walls are some kind of glitches, not a feature of the algorithm when you move in strange patterns.

I wouldnt mind bringing my structures over. I have them all screenshotted but I like my pristine little place in the world.
