Changelog & Known Issues for 0.4.0
This mod was originally made to offer mod devs methods for doing things that are typically thought of as impossible, hacky, tedious, or maybe even require a third party java library. It now additionally serves as an API that can be used to load and run mods on multiple versions & mod loaders.
Supported Versions
The status indicators are as follows:
BROKEN → The API has been implemented in this version, but it is not yet able to load.
FUNCTIONAL → There are no known major issues specific to this version.
LOADABLE → The game can load in this version, but entering a world is not yet possible.
PLANNED → The API has not yet been implemented for this version, but it will be soon.
PLAYABLE → Worlds are able to load in this version, but there may be stability issues

Getting Started
Features
I will be writing a more in-depth wiki at some point, but in the meantime here are a few helpful things you can do:
- Easier file creation and manipulation
- Generic image rendering to the screen
- Global nbt data storage and retrieval
- Support for radial gui elements and some helper methods regarding that
- Custom async tick events able set by millisecond
