SliceWorld

Welcome to the Hangar Open Beta. Please report any issue you encounter on GitHub!

A challenging Minecraft Paper plugin that transforms the world into randomly sliced floating platforms.

Turn Minecraft into a fragmented survival challenge where every block matters.

SliceWorld is a challenging Minecraft Paper plugin that transforms the Overworld, Nether, and End into randomly sliced floating fragments.

Build from platform to platform, make every resource count, and find your own way to reach the End and defeat the Ender Dragon.

SliceWorld Overworld

SliceWorld is currently in beta.

🌎 A World Torn Apart

SliceWorld doesn't replace Minecraft's terrain with custom islands.

Instead, Vanilla terrain is generated and then reduced to randomly selected horizontal and vertical fragments.

Biomes, caves, ores, structures, mobs, vegetation and other Vanilla features can still exist — but only whatever happens to survive the slicing.

Some chunks disappear completely.

Others might contain exactly the resource you've been searching for.

The challenge isn't just finding what you need.

It's figuring out how to reach it.

SliceWorld Survival Gameplay

🔥 The Nether Isn't Any Safer

The challenge continues beyond the Overworld.

The Nether can use the same sliced generation system, turning normal exploration into a dangerous journey between isolated fragments surrounded by lava and the void.

SliceWorld Nether

Blaze Spawners required for normal progression are preserved where they can be reliably detected.

Nether portals remain connected to the SliceWorld challenge, allowing normal Overworld ↔ Nether progression without returning players to the server's regular dimensions.

And if that still isn't difficult enough, the End can be sliced too.

⚙️ Configuration

Each dimension can be configured individually.

The default configuration is:

language: en

dimensions:
  overworld: true
  nether: true
  end: true

For each dimension:

true – enables sliced terrain
false – keeps normal Vanilla terrain

For example:

language: en

dimensions:
  overworld: true
  nether: true
  end: false

This creates a sliced Overworld and Nether while keeping the End completely Vanilla.

This can be especially useful if you want the full SliceWorld survival experience but prefer to fight the Ender Dragon in a normal End.

Lazy Dimension Generation

/sliceworld create initially creates only the challenge Overworld.

The Nether and End are created lazily when they are entered for the first time.

This means their configuration can still be changed before entering them.

Once a dimension has been created, its selected generation mode is stored and later configuration changes will not modify that existing world.

🌍 Languages

SliceWorld currently supports:

en – English (default)
de – German

The language can be changed in:

plugins/SliceWorld/config.yml

Language changes are applied automatically the next time a player joins.

Join messages provide contextual information depending on the current challenge state, and displayed commands can be clicked directly in chat.

🎮 Commands

Command	Description
`/sliceworld create`	Creates a new SliceWorld challenge and prepares the initial safe spawn.
`/sliceworld start`	Starts or continues the current challenge.
`/sliceworld end`	Leaves the challenge and returns safely to a normal Overworld.
`/sliceworld reset`	Deletes the current challenge and creates a new one with a new random seed.

The shorter alias can also be used:

/sw

🔐 Permissions

`sliceworld.use`

Allows access to:

/sliceworld create
/sliceworld start
/sliceworld end

`sliceworld.admin`

Allows access to:

/sliceworld reset

Both permissions default to server operators.

🎒 Separate Challenge Inventories

Normal server worlds and SliceWorld challenge worlds use completely separate player inventories.

The three challenge dimensions share the same challenge inventory:

sliceworld
sliceworld_nether
sliceworld_the_end

This prevents players from collecting resources in a normal world and simply bringing them into the challenge.

Inventory separation also includes:

Inventory and hotbar
Armor
Offhand
Ender Chest
Experience
Health
Hunger and saturation
Potion effects

Traveling between the SliceWorld Overworld, Nether and End keeps the same challenge inventory.

Leaving the challenge restores the player's normal-world state.

👥 Multiplayer

SliceWorld uses one shared challenge world set for all players.

Everyone plays in the same:

Overworld
Nether
End
World seed
Generated terrain

New players without a saved challenge position use the same persistent initial challenge spawn.

This makes it possible to begin the challenge together instead of spawning far away from each other.

Afterwards, inventories, positions, respawn information and other player state are tracked separately for every player.

Multiplayer Beta Notice

Multiplayer support has been implemented and reviewed for common issues, but live testing with multiple accounts is still limited during the beta.

Feedback from multiplayer servers is especially welcome.

💀 Respawning

Dying inside the SliceWorld challenge will never send the player back into a normal server world.

SliceWorld supports:

Challenge beds
Nether respawn anchors
Persistent safe spawn fallback

If no valid personal respawn location exists, the player returns to the persistent safe spawn in sliceworld.

This keeps deaths inside the challenge without requiring players to manually re-enter it.

🔄 Resetting the Challenge

Running:

/sliceworld reset

completely resets the current challenge.

SliceWorld will:

Safely evacuate players from challenge dimensions
Restore their normal-world inventories
Delete the existing SliceWorld dimensions
Clear challenge inventories and saved positions
Generate a new random challenge seed
Create a fresh SliceWorld Overworld

The Nether and End remain ungenerated until they are entered again.

Every reset therefore gives you a completely new challenge.

💡 Inspiration

SliceWorld was inspired by Minecraft challenge videos featuring worlds divided into thin slices, particularly challenges played by BastiGHG.

I really liked the core idea and wanted to create my own interpretation of the challenge with randomized slice widths and heights, completely empty chunks, and sliced versions of the Overworld, Nether, and End.

SliceWorld is an independent, unofficial project and is not affiliated with or endorsed by BastiGHG.

📦 Installation

Download the latest SliceWorld .jar.
Stop your Paper server.
Place the .jar inside your server's plugins directory.
Start the server.
Create your challenge:

/sliceworld create

Start your adventure:

/sliceworld start

That's it.

Now figure out how to survive. 😄

📋 Requirements

Minecraft: 1.21.4
Server: Paper
Java: 21

No additional plugins are required.

🧪 Beta & Feedback

SliceWorld is currently released as a beta.

The core challenge has been extensively played and tested in singleplayer, including progression through the Overworld and Nether.

Multiplayer functionality is implemented, but testing with several live players is still limited.

If you encounter a bug, unexpected world generation, inventory issue or other problem, please report it on the project's GitHub issue tracker.

Feedback about the difficulty and overall challenge experience is also welcome.

🛠️ Development

SliceWorld was developed with the assistance of AI tools, including OpenAI Codex.

The project concept, feature design, testing, configuration, and release decisions are managed by RodJays.
