About this project
What does Rad Radiation add?
Radiation mod focusing around modpack support. Allowing for many possible ideas of how
radiation should affect and function. Configs for mechanics, JSONs for specific data
around blocks, biomes, dimensions, entities, items, and effects.
Every value is datapack driven by ID or tag, and optionally conditional on item NBT,
dimension, or biome. Radiation sickness stages are JSON too (effects, attributes,
damage, or even running commands).
Sealed rooms and shielding, Geiger counters, Rad-X and RadAway, absorbers,
plus a provider API for addons. Jade, Curios, and couple backpack mod support.
Still in development, but used in Biohazard as part of a commission.
Thanks to the many people who have helped me make this mod! Y'all know who you are!
