An addon for Alex's Caves that changes how you obtain and craft nuclear bombs, as well as improving the effects of nukes on the environment.
> WARNING: It is recommended to turn OFF item drops from the nuke in Alex's Caves configs! Also setting the nuke radius in Alex's Caves to 6 or higher is recommended—the explosions have been optimized for larger radii.
Dependencies: Citadel, Patchouli, Cloth Config, Kotlin For Forge, and Alex's Caves (of course)
To get started, craft a guidebook using a book and alexscaves:uranium (Requires Patchouli). There is also EMI support for the new recipes and in-world block transmutations.
This mod adds:
Spoiler
- Enriched uranium, rod, block
- Overhauled nuclear explosion
- Uranium enrichment process
- Rocket launcher and rocket types
- Uranium arrow
- Uranium candy
- New types of nukes (Mini-nuke, Neutron bomb, Black hole bomb)
- Nuka Cola
- Raygun MkII (And gamma variant)
- Flamethrower
- Railgun
How to enrich uranium: Spoiler
Smelt uranium blocks in an Alex's Caves nuclear furnace to get a Block of Salted Uranium. Then put that block in a Centrifuge and wait (will take a while).
Smelting uranium will leak radiation in the surrounding area so get your hazmat suit on to make sure the nuclear furnace doesnt overheat!
Server side performance settings: Spoiler
Note explosions have been optimized compared to Alex's Caves. For weaker hardware, you can try the following settings, in order of greatest to least impact:
- Turn off "Create glowing irradiated air" in nuclear explosion config (glowing air may cause light updates and significantly increased memory usage)
- Reduce explosion radii for neutron bomb, black hole bomb, mini-nuke (nuke follows Alex's Caves)
- Set effect cloud duration to 0 in nuclear explosion config
You may use this in modpacks!
