Duplicationless
This is not a gameplay mod but a library designed for developers of other mods.
The author created this tool out of frustration from constantly writing the same data tracking and configuration code across all their mods - the process was endlessly repetitive and inefficient.
Instead of copying billions of identical code lines in every new mod, everything developers need has been packaged into one convenient library.
Features
If you look at the mod's source code, beyond the main entry point and mixins, you'll find that every section serves as a comprehensive API for mod developers.
This project emerged from the author's pursuit of efficiency and automation of routine programming processes.
For those developing mods who are tired of repeatedly programming the tracking logic for block states and entities across chunks and dimensions - this library will prove to be an indispensable assistant.
