About this project
What does Nuclearistic Core add?
⚠️ ! IMPORTANT !
Due to indirect circumstances, the development of this project will progress at a slower, more measured pace for the time being. However, please rest assured that work has not stopped and will continue moving forward. Additionally, some textures may occasionally lack detail or appear low-quality. Please note that these assets are strictly temporary; all such textures will be fully replaced with high-quality versions before the release of version 1.0.0.
Rebranding Announcement!
Attention, everyone! The mod "Assembly Expansion" has been officially rebranded to "Nuclearistic Core".
I decided to rename the mod because I believe the new name fits the mod and its core concept more accurately. The project is under active development, and all future updates will be released under the new name Nuclearistic Core.
Note for players: If you are upgrading from old alpha versions, please back up your worlds, as the Mod ID change will remove items from existing saves.
Nuclearistic Core
Nuclearistic Core is a technology mod currently in its alpha stage. It introduces resource processing mechanics, energy generation, and basic automation components.
Main features of the mod:
- Tin Ore and Lead Ore, with plates and dusts.
- Hevea (Rubber Tree): Generates in swamps and jungles. Comes with a full wood set.
- Rubber Acquisition: Acquisition mechanics: find a rubber tree, cut it with a special knife, place a bowl on any lower block (but not at the same height as the log block), and wait until you have a bucket full. Then the latex will harden, and you will get 4 latex discs. After that, you will be able to smelt them into rubber.
- Engineer's Hammer: Crafted from 2 sticks and 2 iron ingots. Essential for making plates.
- Energy & Machines:
- Electric furnace. Similar to a regular oven, but consumes 20 FE/t instead of fuel.
- Generator. Converts energy from almost anything that can burn.
- Crusher. Helps double ores!
- Mechanical sinterer. Needed for efficient production of mossy blocks and steel..
- Cables: Currently, only copper cables are available, conducting 128 FE/t. The conductivity of the cable affects only the transmission speed of energy. Cables can be insulated with rubber—1 cable + 1 rubber equals 1 insulated cable. If they are not insulated, touching them can give you an electric shock.
On Easy, Normal, and Hard difficulty levels, there will be damage of 1, 2, and 3 hearts respectively. Uninsulated copper cables are crafted from 2 copper ingots and 1 redstone, yielding 8 cables. - Components: Added a Battery (stores up to 2 kFE) and a Circuit (recipes for upgrades and circuits are not yet implemented).
You can find additional information in the version descriptions!
Future Plans & Roadmap (Not implemented yet):
- Silver Ore
- Uranium & Nuclear Reactor
- Advanced resource processing systems
- Biotechnology
- More Machines
