🧱 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

Install Fabric Loader for Minecraft.
Install Fabric API from Modrinth.
Drop OneBlock-<version>.jar into your mods folder.
Launch with the Fabric profile and choose the OneBlock world type.
(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

Create a Fabric server on Minecraft.
Place both Fabric API and OneBlock in the mods folder.
In your server.properties find level-type and set it to oneblock\:oneblock NOTE: if a vanilla world is still being created, try with oneblock:oneblock
To enable per-player islands, add oneblock\:oneblock_multiplayer to initial-enabled-packs in server.properties.
Start the server and enjoy personal or shared islands.
(Optional) Enable datapacks for void worlds: oneblock\:oneblock_void_nether, oneblock\:oneblock_void_end, or oneblock\:oneblock_no_island. NOTE: If they dont work, add them without the \ in the text

🌴 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
