Alexy’s Radiation Lib

☢️ Alexy’s Radiation Lib — Zones, Radiations & Emissions

RadioLib is a STALKER/Stalcraft-inspired radiation system for Forge 1.20.1. It is not plug-and-play: it needs configuring, and is aimed at server admins who want a radiation system on a modded server.

The mod is the engine (radiation, zones, damage, sync); the content (loot, quests, balance) is left to you, via config and KubeJS.

**You can find a detailed “wiki” in the ./config/radlib/wiki.txt that explains every command, feature and KubeJS api usage.**

Features

Three radiation types

rad (ionizing), bio (contamination), and psy (psychic). Each has its own damage type, decay rate, and debuff effects. All of them bypass armor — only configured anti-rad gear reduces them.

Zones

Define radioactive areas with a selection wand, as boxes or per-block contact hazards (e.g. seagrass, magma). There are 6 tiers, from 0 (faint background) to 5 (kills an unprotected player in seconds). A toggle key (default ALT+Z) shows zones as colored wireframes.

Bunkers

Safe zones that block radiation intake and protect from emissions while you are inside them.

Emissions

A timed, server-wide event. During it the sky is replaced by a custom skybox, clouds are hidden, fog thickens, ambient sounds play, and a warning shows above the hotbar. Players who are not in a bunker take lethal damage after a short exposure. Timings are set per command and synced to clients.

Attributes / gear

Radiation resistance, dose tolerance, and recovery are attributes you assign to armor or Curios via config. There are also negative attributes for items that irradiate the wearer.

Geiger counter

A Curios item that plays a ticking sound whose intensity follows the radiation tier at your position.

Anti-rad consumables

Any food or drink can be configured to remove dose, grant temporary resistance, or speed up decay.

Debuffs

Per-type poisoning stages (low to acute) with configurable damage, chance, and potion effects. Configuration is in JSON (comments supported), and a wiki.txt reference is generated into the config folder.

For servers

• KubeJS API — a facade plus events (emission phase, death by radiation, zone enter/exit, stage change) for scripting loot, quests, auto-emissions, zone gating, etc.
• Multiplayer — zones sync to clients automatically; the server is authoritative for damage.
• Commands — zones, bunkers, emissions, and dose management are handled through /radiation.

Quick start

1. Install the mod (Forge 1.20.1) with Curios.
2. /radiation tool give, select two corners, then /radiation zone create rad 4 wasteland.
3. Press ALT+Z to view the zone.
4. /radiation emission start 30 60 to test an emission.
