I don't know my version or loader



Irradiated is a conversion of Cold Sweat by Mikul, ChubbyMomo, & SkinnyMomo, into a radiation mechanic.

Dangerously high radiation will hurt and kill the player!

The two added effects are Rad Resistance and Radiation, which respectively reduce the effects of radiation, and apply radiation to the player. Config contains options to make food/usuable items increase or reduce radiation, so you can customize how difficult you want your experience to be!
Irradiated also contains geiger counter sound effects to help let you know when you're around something radioactive, and add to the overall ambience/feel of it.
This mod is designed to be a library mod which modders or modpack creators can use for a simple, efficient and robust radiation system. It requires configuration to add block/item/biome/etc radiation effects, but that process is relatively simple and the config has examples.
Warning: this mod MAY be incompatible with the base Cold Sweat mod. This has not been tested, but due to the fact that it is a branch of Cold Sweat, there's a high likelihood that there will be some conflicts. Use together at your own risk!
