Description

One Block Re:forged

DOWNLOAD · DISCORD · SOURCE CODE

One Block Re:forged adds native OneBlock progression to Minecraft Forge 1.20.1. Mine your Origin Block to unlock new phases, mobs, traders, and advancements, or build custom phases for your modpack.

What you can do

  • Native OneBlock progression — mine the block, get the next one, climb through phases as your mined-block count grows.
  • Built-in phase timeline — nine progression stages from Progress through Step 9, each with its own block pool and passive mob unlocks.
  • Custom phase support for pack authors — add or override phases with simple datapack JSON, no coding required, so modpacks can add modded blocks, mobs, and loot with full control over weights, conditions, and guaranteed drops.
  • Custom trader pools — override stage and visiting trader offers per pack, or let the mod use its own built-in trades.
  • Mob crate & visiting trader system — mobs spawned by your OneBlock are tracked and released through visiting traders, safely and without scoreboard hacks.
  • Progress bossbar — see how close you are to the next stage.
  • Native end portal handling, mob-use achievements, and a full custom advancement tree — tips, progression milestones, and mob-related achievements are all handled by the mod itself.
  • Pack-developer tools — validate, preview, and simulate phases before shipping a modpack, with dedicated OP-only commands and a public help command for everyone else.
  • Angel Block–style placement — the Origin Block places normally against a face, or floats into open air ahead of you when you right-click nothing.
  • Config-first design — nearly every system (stage actions, traders, world border, end portal, mob crates, achievements, etc.) can be toggled per modpack.

I designed this mod to work with Void One Block. I have not tested it with other void-world or skyblock mods.

Install, update, and check compatibility

Compatibility

One Block Re:forged is built specifically to work with my void world mod, Void 1 Block. It only takes ownership of the block position once it's registered as a OneBlock, and lets Void 1 Block handle world/spawn management while it handles progression. No setup is required, it's compatible out of the box since I built both mods to work together.

This mod has not been tested with other void-world/skyblock mods and is not designed with them in mind.

Custom Phases for Pack Authors

Drop JSON files into your datapack to add or replace phases, no Java required:

data/<namespace>/oneblockreborn/phases/<file>.json

Supports weighted block/mob/chest entries, mob count ranges, NBT, per-entry conditions (dimension, biome, mined range, time, weather), guaranteed exact-count drops, and stage actions (world border, stage traders, end portal, milestone messages).

Full documentation is in the mod's README, on the project's GitHub repository.

About this project

Credits

One Block Re:forged's progression design, phase thresholds, and gameplay concepts were inspired by the OneBlock world/datapack by its original author on CurseForge. That project is the origin of the OneBlock format this mod reimagines natively for Forge 1.20.1. All code, assets, and data in this mod are my own original work, written from scratch to bring that gameplay concept to a modded environment; no files from the original datapack are bundled with this mod.

If you enjoy the OneBlock concept, please check out the original datapack and give credit to its creator: 👉 https://www.curseforge.com/minecraft/worlds/oneblock

One Block Re:forged

OneBlock Reborn brings the classic OneBlock skyblock experience to Forge 1.20.1 as a native mod, instead of a datapack. Place your Origin Block, start mining, and watch a full progression system unfold entirely, features, phases, mobs, traders, and achievements included, with none of it relying on external datapack scripting to function.
