This is a library I will be using for a bunch of my minecraft plugins, others are free to use it as well.
It currently contains features such as:
- A system for saving code in specific entities to be executed on right click.
- Helpers for saving data to Entities and ItemStacks
- Line renderers, both using particles and block displays.
- JSON file management for human readable save data
- Byte file management for saving whole class instances that can't be serialized to JSON
- Structure helper, for structure copy pastes, movement, or in my case multiblock recognition.
- Some common RNG and miscellaneous helper functions
