Create Nuclear

# Changelog ## \[2.0.0\] ## Reactor Overhaul: * Added two new reactor sizes (Tier 2 and Tier 3), on top of the original size, each offering higher energy output and a higher acceptable heat threshold. * Added a new liquid input block that lets players supply a coolant fluid to the reactor, alongside a brand new Nitrogen fluid to use with it. Reactor coolant fluids are fully configurable via datapack. * Added a new reactor alarm block. It can be triggered by a redstone signal, and is also triggered automatically by the reactor itself when heat reaches a dangerous level, warning players ahead of a meltdown. * Added a brand new nuclear explosion, with its own mushroom cloud, custom model and dedicated sound, replacing the previous plain explosion. * The item input, fluid input, and alarm blocks can now be placed anywhere on the reactor's structure, instead of being restricted to fixed positions like before. * The reactor's heat system has been reworked to follow the official fuel-to-coolant ratio, fixing cases where proximity heat was calculated incorrectly and made reactors behave inconsistently. * Overheating is now properly capped based on the fluids used, so reactors can no longer exceed their intended maximum heat. * Rod and fluid types are no longer hardcoded to uranium/graphite — the reactor now works dynamically with whichever rod and fluid types are configured, making it easier to support new fuels and coolants in the future. * Fixed several issues causing incorrect reactor readiness checks regardless of which fuel or coolant was actually loaded. * Reworked the RPM/output system to match the new energy values, and smoothed out output flickering with a new heat buffering system. * Fixed a bug where items placed in the reactor could be lost during certain block state changes. * Improved reactor structure rendering performance, especially noticeable on larger reactor tiers. ## Reactor Display & Interface: * Added support for Create's Display Boards / Display Links on the reactor controller, letting players show live stats (heat, fuel, coolant, output, size) on in-world displays. * Rod stats (heat, proximity heat, timer, ratio) are now displayed directly in the item's tooltip, including for the Thorium rod. * Rods can now be added through a datapack, or by other mods, without needing custom code — they will show up with their stats in the tooltip just like the built-in ones. * Fixed incorrect text formatting and fluid density values shown on the reactor controller. ## Radiation & Iodine Protection: * Radioactive items (such as raw Uranium and Uranium Ore) now emit radiation on their own when carried in your inventory, on top of environmental sources like irradiated biomes. Reactors themselves don't emit radiation — only a nuclear explosion does, which is also what creates the irradiated biome around it. * Added a new Radiation Resistance attribute to the mod, used by both the Iodine effect and the anti-radiation armor to reduce radiation exposure. * Radiation exposure now uses a dose-based contagion system instead of a single on/off effect, making radiation sickness feel more gradual and consistent. * Radiation now affects all living entities, not just players. * Added the Iodine protection effect, including new potions, a brewing recipe chain, tooltips, and icons. * Added new anti-radiation armor models, including colored variants, with improved visuals. * Added new irradiated heart icons to the HUD, and the radiation vision overlay is now properly hidden in Creative and Spectator mode. ## World Generation & Irradiated Biome: * Added the Irradiated Land biome. It doesn't generate naturally — it spreads around the area of a nuclear explosion, converting the terrain there. The idea of irradiated zones has been part of the mod since its early days (vision overlay, irradiated mobs), but this is the first time it's backed by an actual biome. * Adjusted Thorium and Uranium ore generation rates in the world. * Added the Biome Irradiation Extractor along with its crafting recipe chain, including the new Reinforced Glass Bottle, allowing players to revert irradiated biome zones. ## New Items & Blocks: * Added the full Thorium chain: Thorium Ore (and its Deepslate variant), Raw Thorium, Thorium Block, Thorium Dust, Thorium Ingot and Thorium Nugget, all the way up to the new Thorium Rod usable in the reactor. * Added Nitrate Ore (and its Deepslate variant), along with a new processing chain (Nitrate, Nitrate Sludge, Nitrogen Concentrate, Cooled Nitrogen Concentrate) used to produce the new Nitrogen fluid. * Added a new Snow Powder recipe processed with Create's fans, used as part of the new Nitrogen production chain. * Building the reactor's item, fluid input, and output blocks now requires a Create Deployer instead of simply placing the item, in line with Create's automation style. * Added the Irradiated Cow, a new spawnable mob like the other irradiated animals. Still a work in progress at this stage. ## Advancements: * Reworked the advancement tree into a clearer, linear progression covering every stage of building and operating a reactor, including new Tier 2 and Tier 3 milestones. * Added several new nuclear-themed advancements for surviving reactor hazards, crafting key items, and reaching late-game milestones. * Placement-related advancements are now correctly awarded through the reactor controller instead of individual parts. ## Sound & Ambience: * Added dedicated sound effects for reactor assembly, disassembly, and the new reactor alarm block. * Added a running hum sound while the reactor is active. * Added a ringing sound effect that plays after a nuclear explosion. * Added ambient music to the Irradiated Land biome. * A few other new sound effects were added in this version (including Geiger-counter sounds and some reactor/explosion variants) but aren't hooked up to anything in-game yet. ## Quality of Life: * General performance improvements to radiation checks and reactor structure scanning, reducing lag in larger builds. * Various tooltip, formatting, and text clarity fixes across reactor and armor items. ## Bug Fixes: * Fixed reactor output flickering caused by rapid heat fluctuations. * Fixed several cases of items being lost when reactor blocks changed state unexpectedly. ## Configuration: * Added several new config sections (biome restoration, explosions, notifications, radiation, reactor heat) letting server owners tune these systems. * Reworked and renamed several existing config values (reactor rods, world generation, general settings) for clarity and consistency. *** If you want to help us translate to other languages: [https://crowdin.com/project/createnuclear](https://crowdin.com/project/createnuclear) Some translations were verified/completed using AI, if you find any issues let us know on our Discord!
