About this Mod
Researcher
A (mostly) data-driven research system for Minecraft inspired by Factorio.
This mod does nothing on its own, and is meant to be used by other mods, datapacks and modpacks.
Currently, only the 26.1.x branch is suppoted.
Features
- Lock recipes behind researches!
- Data-driven! (Mostly)
- Research syncing! (CAUTION: Highly experimental feature)
- Sync research progress between teams or across all players!
- It's like advancements, but with a count
Boring Legal Stuff
The mod icon and the default research texture are both a modified version of this, and are therefore licensed under CC BY-SA 4.0. Everything else is licensed under the MIT license.
Why not use advancements?
Sure, you could use the doLimitedCrafting gamerule with advancements to lock recipes, but it's disabled by default. Force-enabling it could easily mess with other mods. Furthermore, advancements are somewhat limiting when it comes to unlock conditions.
How does it work internally?
This mod takes advantage of Minecraft's criteria system, which is used by advancements. Unlike advancements, to complete a research, the criterion must be triggered a set number of times.
Research progress is saved per-world, alongside stuff like advancements.
