About

🧱 OneBlock

Survive and thrive on a single regenerating block in the void.

Start your journey on a small floating island with one special block at its center. Every time you break it, something new appears — dirt, wood, ores, even rare materials from the Nether and End. Build your world one block at a time while facing random events, monster waves, and evolving challenges.

Perfect for solo adventures or multiplayer servers with per-player islands and fully customizable gameplay via an in-game admin panel.

Compatibility: Fully supports Minecraft 1.21.11 (Fabric), including newly added mobs and blocks. All new 1.21.11 content is integrated into OneBlock progression, events, and drops.


🧱 Installation & Setup

💻 Singleplayer

  1. Install Fabric Loader for Minecraft.
  2. Install Fabric API from Modrinth.
  3. Drop OneBlock-<version>.jar into your mods folder.
  4. Launch with the Fabric profile and choose the OneBlock world type.
  5. (Optional) Enable resource packs for void dimensions or to disable the starting island.

🎮 You'll spawn on your small island with a regenerating OneBlock at its heart.


🌐 Multiplayer

  1. Create a Fabric server on Minecraft.
  2. Place both Fabric API and OneBlock in the mods folder.
  3. In your server.properties find level-type and set it to oneblock\:oneblock
  4. To enable per-player islands, add oneblock\:oneblock_multiplayer to initial-enabled-packs in server.properties.
  5. Start the server and enjoy personal or shared islands.
  6. (Optional) Enable datapacks for void worlds: oneblock\:oneblock_void_nether, oneblock\:oneblock_void_end, or oneblock\:oneblock_no_island.

🌴 Starting Island

You begin on a small island for safer starts:

  • 🟩 Overworld: Grass (Y=63) over dirt (Y=62).
  • 🌋 Nether: Netherrack island.
  • 🌌 End: End Stone island.

In multiplayer, each player spawns 1000 blocks apart in a cross-pattern grid.

The starting island can be disabled with the oneblock\:oneblock_no_island datapack.


🎨 Core Features

🧱 Regenerating OneBlock

The heart of the mod — a single block that respawns infinitely with new materials based on your progression.

🌍 46 Biome Cycling System

Experience all of Minecraft's biomes through your OneBlock:

  • 36 Overworld Biomes: From plains and deserts to deep dark and lush caves
  • 5 Nether Biomes: Wastes, crimson forest, warped forest, soul sand valley, basalt deltas
  • 5 End Biomes: The End, highlands, midlands, barrens, small islands

Each biome brings its unique blocks — jungle wood and bamboo, cherry blossoms and pink petals, warped fungi and crimson vines, chorus plants and end rods.

🔓 Dimension Unlocks

Visit the Nether or End to permanently expand your OneBlock's material pool:

  • Nether: Unlocks basalt, blackstone, quartz, crimson/warped wood, fungi, vines, and more
  • End: Unlocks purpur, end stone, chorus plants, end rods, and shulkers
  • In multiplayer, progress is tracked per-player
  • After 10k breaks, by default, end portal frames can drop as an item.

Note: New blocks and mob types introduced in 1.21.11 are included where appropriate across stages and dimensions.

⚖️ Dynamic Block Weighting

Block selection evolves as you progress:

Stage Useful Structural Rare Random
0–2,500 70% 25% 5% 0%
2,500–5,000 50% 35% 5% 10%
5,000–7,500 30% 40% 5% 25%
7,500–10,000 10% 35% 5% 50%
10,000+ 0% 0% 0% 100%

Early game provides essential materials, late game brings variety and challenge.


🎲 Random Events

Every block break may trigger a surprise:

  • 🪙 Item Drops: Random items spawn nearby or in chests
    • Configurable drop count (1-64 items)
    • Dimension-unlocked items from Nether and End
    • Special lava bucket drops for easy lava access
  • 💀 Monster Waves: Instant combat encounters with scaling difficulty
  • 🐑 Friendly Mobs: Peaceful animals, villagers, and wandering traders

All events scale with difficulty and progression.


💀 Monster Waves

Dynamic combat encounters that evolve with your progress:

  • Sunlight-Aware: Burning mobs spawn only at night; others spawn anytime
  • Dimension Scaling: Nether and End mobs join after visiting those dimensions
  • Difficulty Scaling: Wave size and frequency adapt to game difficulty
Stage Enemies
Early Zombies, Spiders
Mid Skeletons, Creepers, Husks, Strays
Late Endermen, Witches, Blazes, mixed chaos

🐾 Friendly & Aquatic Mobs

Life evolves with your progress:

  • 🐮 Farm Animals: Cows, pigs, sheep, chickens, rabbits
  • 🐝 Neutrals: Wolves, llamas, bees, foxes
  • 🦜 Ambient: Parrots, cats, turtles
  • 🐠 Aquatic: Fish, axolotls, frogs, dolphins (needs 5×5 water pool)

🧪 Custom Recipes

OneBlock adds special crafting recipes to help you survive in the void:

💧 Ice Compression → Water Bucket

Compress ice blocks to extract water:

    [Ice]
[Ice][Bucket][Ice]
    [Ice]
  • Recipe: 4 ice blocks (any type: ice, packed ice, or blue ice) + 1 bucket
  • Result: 1 water bucket
  • Why: Ice spawns naturally from the OneBlock. Compress it to get renewable water!

🔥 Magma Compression → Lava Bucket

Compress magma blocks to extract lava:

    [Magma]
[Magma][Bucket][Magma]
    [Magma]
  • Recipe: 4 magma blocks + 1 bucket
  • Result: 1 lava bucket
  • Why: Magma blocks spawn from the OneBlock. Compress them for renewable lava!

These recipes give you renewable access to water and lava — essential for survival, farms, and automation in the void.


🧩 Included Datapacks

Enables per-player islands — each player gets their own OneBlock 1000 blocks apart.

oneblock_void_nether

Removes all Nether terrain generation, leaving only void for a true skyblock experience.

oneblock_void_end
