About

Start your Minecraft journey with a single chunk. Gathering Chunks transforms world generation into a strategic experience where you expand your world one chunk at a time, gathering resources and choosing your next foothold as you grow from a lone plot into a sprawling empire.

Why This Fork?

The original Chunk by Chunk by immortius is an excellent mod that deserves to stay alive. With the upstream project appearing discontinued (last update over a year ago), this fork picks up the torch:

• Keeps the mod updated for current Minecraft versions
• Currently supports Fabric and NeoForge on Minecraft 1.21.1 (NOT 1.21.11!!)
• Future support planned for newer versions
• Forge will not be supported in this fork. For Forge 1.20.1, visit the official mod page

How to Play

1. Start small. You begin with a single chunk in an otherwise empty world.
2. Find chests. Special chests are scattered around containing items needed to craft Chunk Spawners.
3. Expand. Place Chunk Spawners next to empty chunks and activate them to unlock new terrain.
4. Progress. Use World Cores, Forges, Scanners, and Menders to manage and automate your growing world.

Blocks and Items

Core Items

Chunk Spawner Spawns a chunk from the original world seed at a specific location. Place it adjacent to an empty chunk and interact with it to activate.

Unstable Chunk Spawner Spawns a completely random chunk. Same activation method as the standard Chunk Spawner.

Biome-Themed Spawners (Overworld) Spawn chunks matching a specific biome type. Available biomes: Forest, Badlands, Desert, Jungle, Mountain, Mushroom, Plains, Rocky, Savanna, Snow, Swamp, Cherry, Taiga, and Ice Spikes.

Biome-Themed Spawners (Nether) Nether Wastes, Basalt Deltas, Crimson Forest, Warped Forest, and Soul Sand Valley.

Utility Blocks

World Core The central crafting component, created by fusing four World Crystals. Can also be found in Bedrock Chests.

World Forge Crystallizes common materials like dirt and stone into World Fragments, and processes higher-tier materials using fuel.

World Scanner Reveals ore and element concentrations in surrounding chunks, both spawned and unspawned. Requires fuel to operate.

World Mender Automates chunk spawning by periodically applying Chunk Spawners stored inside it to the nearest empty chunk.

Chunk Engine Increases your chunk limit or keeps your chunks loaded. Entirely optional.

Bedrock Chest A sealed chest found at the bottom of chunks. Opens only once most of the blocks above it have been cleared. The threshold is configurable.

Crafting Materials

World Fragment The smallest unit of crystallized world essence.

World Shard Formed by fusing four World Fragments, either at a crafting table or in a World Forge.

World Crystal Formed by fusing four World Shards, either at a crafting table or in a World Forge.

Version Checking

Starting from version 2.2.5 (Beta 3.4, Hotfix 2), the mod performs an automatic version check on launch to notify you of available updates.

What is sent: Your current mod version number only. What is not sent: No personal information, IP addresses, game data, or any other identifiable data.

The entire update checking implementation is open source. You can audit it yourself by reviewing UpdateChecker.java in the GitHub repository. The code is straightforward and requires only basic programming knowledge to verify.
