I don't know my version or loader
Duplicationless
This is not a gameplay mod — it’s a library.
I made this because I was tired of writing the holy ****ing same data tracking and config code again, again, again, and again in my mods.
So instead of copy-pasting the same ten trillion lines every time, I decided to pack them all into one place — and here we are.
What it does
https://github.com/MCTeamPotato/Duplicationless/tree/1201/src/main/java/me/kall/duplicationless
Except the main entrypoint and mixins, every class is an API.
Note
This project basically exists because I got lazy (in a productive way).
If you’re also tired of rewriting entity or block tracking logic, maybe you’ll find it useful too.
