About this project
What does Hellion's API add?
Hellion's API
Is an API used in HellionGame's projects. It allows for the easy registration of:
- Blocks
- Items
- Effects
- Potions
- Entities
Simultaneously on Forge, Fabric and NeoForge, all through a single line of code!

It also allows the automatic creation of block items with a single method call, too!
This exists to make Hellion's mods faster to make and easier to update.
