For all my mod devs out there - This provides a lot of useful stuff, especially if you're a worldgen modder!
The API includes the following:
- AutoRegistration system (1.18+ only). Register any field with only a simple annotation, regardless of mod loader!
- Custom reimplementation of Jigsaw Manager with improved performance and custom pool element types with various new properties. Check out the Better Dungeons code to see it in action.
- New criteria trigger for safely locating any structure. If the given structure doesn't exist, the trigger simply fails rather than instantly passing (unlike vanilla).
- Interfaces for JSON serialization & deserialization with built-in type adapters.
- Simple, lightweight math utilities for vectors and column positions
- BlockStateRandomizer and ItemRandomizer, data abstractions that make adding block and item randomization to your structures incredibly simple. I use these for all of my mods!
If you're curious, you can check the code for my mods (especially the newer ones) to see how things work. Feel free to ask me any questions on Discord!
ABOUT THIS LISTING
This page describes YUNG's API by YUNGNICKYOUNG. The description and screenshots are the author's own, imported from their listing on Modrinth on 3 October 2026: https://modrinth.com/mod/yungs-api
Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.
The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.
Requirements
Game versions
1.21.1
1.21
MOD LOADER
This release is built for Neoforge. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.
GAME VERSION
Built for Minecraft 1.21.1, 1.21. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.
THIS IS A LIBRARY
On its own it adds nothing you can see. It is here because other mods require it, and installing it is usually something another mod asked you to do.
DEPENDENCIES
Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.
Installation
1. Install Neoforge for the Minecraft version you play, if you have not already.
2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.
4. Launch the game with the Neoforge profile selected.
ON A SERVER
Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.
UPDATING
Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
This release downloads from cdn.modrinth.com, not from us, so
there is no checksum to compare against. Scan the archive before you unpack it.
Tell us if something is wrong — a file that will not work, content taken from
someone else, or anything that looks unsafe. Reports go to our review team, not
to the author.
