This is very minimal expansion of the nothing skyblock challenge.

The mod tries to make minimal changes to vanilla minecraft while also providing the player with a world where every single block is placed by/generated by the player.

Worldgen Features

• Completely void worldgen. You still get biomes and structures.
• Stronghold portal rooms don't spawn. You get a starting portal.
• Ender dragon doesn't spawn by default, neither the exit portal. You have to respawn the dragon yourself.
• Beware hardcore players would be trapped if they go through the portal.
• Chunk regen exploits won't work.

Datapack features

• The "zenxarch:skyblock" chunk generator has the same codec as noise chunk generator with optional "spawnHeight" for spawn platform.
• The spawn platform spawns at y=0 (defined in world preset) and is defined by a single file 'data/zenxarch/structure/spawn_platform.nbt'
• The "zenxarch:flatblock" chunk generator has the same codec as noise chunk generator with list of "layers" with blocks and height for flatblock layers.

    {
      "type": "zenxarch:flatblock",
      "biome_source": {
        "type": "minecraft:multi_noise",
        "preset": "minecraft:overworld"
      },
      "layers": [
        {
          "block": "minecraft:bedrock",
          "height": 1
        },
        {
          "block": "minecraft:dirt",
          "height": 2
        },
        {
          "block": "minecraft:grass_block",
          "height": 1
        }
      ],
      "settings": "minecraft:overworld"
    }

Extra Features

• Fixes wandering traders not being able to spawn on snow layers
• Following are all enabled by default and controlled by gamerules
• Magma blocks (just like mud) drip lava
• Magma drips lava first, then converts to netherrack
• Falling dripstone crushes stone into sand
• Pigs spawn on mud
• Adds gamerules to control wandering trader spawn rates.

How to start a new world

Just select the Skyblock world preset in create world menu

OR select the Flatblock world preset and customize it

(currently reuses superflat customization screen)

Future plans

• Probably add a superflat world preset with all biomes/structures.
• Add a farming method for sand.
• Add netherrack/nylium to nether portal extension blocks.
• Add other renewable.
• Add option to use the bonus chest feature to get a bonus chest.
• Bonus chest spawn with different skyblock loot depending on game difficulty
• Different starting islands using datapacks

Credits

• FrozenLib for dripstone code
• Carpet sky additions reborn for worldgen code
• Protosky for worldgen code
• Kenedian. Their video inspired the idea of getting obsidian from the end. I did copy the empty end and the starting portal block from their video. Also a very good video that lists all the renewable stuff and how to get them in skyblock.
• JokeyPokey and others for taking skyblock to the extreme + videos,theory and other stuff

Btw there isn't code included from these projects. I just looked at these to figure out stuff like empty worldgen,fix end portal location,dripstone override.
