Vanilla One Block

This data pack generates a single grass block at the very bottom of the world in a Snowy Taiga biome (at Y=-64). The world spawn point will be moved to this grass block at Y=0, allowing mobs to spawn on it. If there is no snowy taiga within 2000 blocks, the locator will fail, and in some worlds the island will not generate.

The world generation pack infinitely creates a void world with properties similar to the original SkyBlock. This means all significant structures will generate with their bounding boxes but without blocks. These structures will appear in the same locations as in a normal world with the same seed. The only blocks that generate besides the starter islands are End portals and sculk sensors.

Structures

Bounding boxes of structures important for SkyBlock will generate at the same coordinates as in a normal world with the same seed, along with some entities:

• Ancient Cities will create the same bounding boxes and sculk shriekers capable of summoning wardens (shrieker locations may not match a normal world)
• Ocean Monuments will generate the same bounding box but without elder guardians (guardian farms can be built as usual)
• Pillager Outposts will appear with the same bounding box and any allays that normally generate
• Strongholds will create only the entrance End portal with partially filled eyes (though it may not match a normal world with the same seed). Under each End portal there will be one block of lava.
• Witch Huts will generate the same bounding box (witch farms can be built as usual)
• Mansions will create any allays that would appear in a normal world
• Nether Fortresses will generate the same bounding box
• End Cities will create any shulkers and ships that would appear in a normal world
• Trial Chambers will generate the same bounding box

The End Dimension

In the End dimension, obsidian pillars and the exit End portal generate as usual. When a player passes through End gates, a small End island will still generate, but the other outer End islands will not generate.

The Initial Grind

This pack adds a feature to speed up the initial grind in Vanilla One Block. The following features apply until the player obtains an iron shovel.

Features

• Over 80% of hostile mobs that spawn will be zombies
• All zombies will spawn with iron shovels, which have an 80% chance of dropping with at least 25% durability (63/250)
• Jumping will cause the player to gain the hunger effect (if there is no zombie in the world)
• When starving, players will be reduced to 4 hearts (initial starvation damage deals 6 hearts instead of half a heart)
• Players will have full knockback resistance
• Daytime will be skipped (if there is no zombie in the world)
• After obtaining the shovel, it will continuously rain until 23 snow blocks are placed

Unobtainable Items

Some items cannot be obtained with such simple world generation. I created an expansion pack that adds mechanics allowing all items, mobs, and advancements to be obtained. Download Sky Void Additions to expand possibilities.

Other Void World Generation Packs

My SkyBlock Collection offers additional options for void world generation. Most notable are other presets where the stronghold generates with a lava pit under the End portal or the entire portal room. There is also a preset that removes all blocks and entities, leaving only a biome map with structure bounding boxes.
