So I looked around for days now and I can't find anything really helpful.
So, what I look for: A tool or any way to create a normal generated Minecraft map or to convert a normal generated Minecraft Map into:
1. A World which is just 1 Block Wide (normal generated not build by myself)
2. A World which is just 1 Chunk Wide (normal generated not build by myself)
3. A World where every second line of blocks is missing
... Yeah, things like that
As far as I know MCEdit doesn't work for newest version.
I tried using Amulet, but this one is bugging alot, when starting the editet world and it takes for ages.
I tried just deleting all blocks except 1 block wide line in Amulet, which took like 10 hours to save.
Then I joined the world and at several locations the blocks didn't get deleted.
Important note: I kinda want the world to be endlessly long (or just like 100.000 blocks)
Second: If possible, would be cool to let the normal ender dungeon get generated like normal, so the enderdragon is still beatable.
Third: The nether and end should be editable too, so they are 1 block / 1 chunk wide too.
I really hope someone can give me some help on this one, really wanna do some challenges with these maps.
So additionally I just thought about it would be a better idea to not take an existing world and delete like billions of blocks, but rather just generate the 1 block wide line, so this wouldnt take ages to save. Just a thought I wanted to add here.
