☢️ NukeCoreCraft

One craftable block. One cinematic nuclear blast. Light the Atomic Core, run, and watch the flash, the fireball, a shockwave that flattens forests, and a mushroom cloud that hangs over a scorched crater full of lethal fallout.

It shows up as NukeCraft in your mod list. Minecraft 1.20.1, Forge 47+.

🆕 What's new in 1.1.1

Visual update only. Blast radius, damage, destruction, fallout and recipes are unchanged, and the Compatible profile still looks exactly like 1.0.0. The new effects are in the Balanced and Cinematic profiles.

• Heat wisps that work with shaders, plus a ground-hugging dust wall that rolls out to the full blast radius and ash that lingers after the blast.
• Red and amber afterglow that lasts longer at night. With shaders off, the sky turns orange, then red-brown, then grey, then back to blue.
• Water blasts: a steam column and a base surge rise over the sea.
• The mushroom cloud no longer drops out after about 70 seconds. It now stays for its whole life.
• Far-away players see the red sky and the heat haze too.

Drop-in update from 1.1.0 or 1.0.0: no new config keys and no world format changes. Mixed 1.1.0/1.1.1 setups still connect, but update both client and server to get the full far-away effects.

💥 The Blast

• Flash: a white-out you can see from up to 2048 blocks away.
• Fireball: a hot glowing core and a double flash, then it climbs into the stem.
• Circular shockwave: the ring spreads as a true circle and flattens trees to stumps as it passes.
• Mushroom cloud: stem, rolling cap, condensation dome and ring, pileus hood, ground surge, dust skirt and dirt stem. With Lingering Cloud on (the default), it hangs and spreads for an extra minute before it fades.
• Scorched terrain: a deep crater, scorched ground, sand turned to glass, melted snow and ice, and thermal-pulse fires.
• EMP: redstone near the blast gets fried.
• Delayed boom: the sound reaches each player at the speed of sound, so distance matters. Echoes and thunder are delayed the same way.
• Blast radius: 500 blocks by default, configurable up to 2000.

🎬 Visual Profiles

• Compatible: the 1.0.0 look, exactly.
• Balanced and Cinematic: the overhauled cloud and every 1.1.x effect.
  • Look: Realistic (default), Stylized or Minecraft.
  • Cloud Style: Smooth (default), Voxel, or Particles (the 1.0.0-style cloud).
  • Cloud Timescale: Cinematic (default) or Realistic.
  • Wind Drift: Off (default), Light or Strong.
  • Lingering Cloud: on by default.
  • Heat Distortion: on by default. Heat shimmer around the fireball with shaders off.
  • Ear Ringing: on by default. Your ears ring and other sounds dip after a close blast.

The cloud is one soft body per blast instead of thousands of smoke particles, so the particle limit can't cut it off.

🌈 Shaders (Oculus, optional)

• Supported: Complementary, Bliss, BSL, Unbound and other packs.
• The cloud draws once per frame under shaders.
• The heat wisps from 1.1.1 work with shaders on.
• The afterglow sky colours (orange to red-brown to grey) are the shaders-off version. Shader packs draw their own sky.

🔊 Sound

• Blast sounds carry out to about 2,000 blocks.
• Near, mid and far blast hits, a 30-second rolling rumble, afterwind, the air rushing back, firestorm crackle and ear ringing, each with subtitles. The 1.0.0 sounds still play.
• Sound is muffled indoors and underwater.
• Nuke sounds follow the Weather volume slider.
• Camera shake scales with distance.

Items & Blocks

Survival Recipes

• Atomic Core: 1 Nether Star in the center, 4 Netherite Ingots in the corners, 4 TNT on the edges.
• Multi-Detonator:
  • Top row: Diamond, Eye of Ender, Diamond.
  • Middle row: Remote Detonator, Comparator, Remote Detonator.
  • Bottom row: 3 Gold Ingots.
  • The Remote Detonator ingredient is Iron Ingots around an Ender Pearl, Redstone and a Redstone Torch.
• Hazmat Suit: Yellow Wool in the usual armor shapes. The helmet has a Glass Pane in the middle.
• Geiger Counter: Iron Ingots, Gold Nuggets and Redstone.

The in-game recipe book shows the exact grid.

☣️ Fallout

• Lethal by default. Near ground zero you get weakness, hunger, poison, wither and damage that can kill you.
• Wear the full hazmat suit to walk the crater safely.
• Contaminated ground stops crops and saplings from growing, and hostile mobs near ground zero get stronger and faster.
• Fallout fades over time.
• Prefer it scary but survivable? Set legacyFallout = false. Radiation is then non-lethal unless radiationHardcore = true.

Config & Commands

• In-game config: press N, or use the Mods menu. The Atomic Core's control panel has quick toggles.
  • On a server, only operators (permission level 2) can change server settings.
• Server settings (serverconfig/nukecraft-server.toml): blast radius, crater depth, fuse time, shockwave speed, fallout strength, duration and lethality, thermal pulse, EMP, and performance budgets.
• Client settings (config/nukecraft-client.toml): visual profile, look, cloud style and the other options above, plus flash, screen shake, haze, particle budget and density, and each cloud phase.
• Commands (op only):
  • /nuke <x y z> [radius] detonates instantly (radius 50–2000).
  • /killnukecloud removes mushroom clouds.
  • /nukecleanup fallout and /nukecleanup fires|effects|all [radius] clean up afterwards.

Upgrading

Back up your world before updating.

• From 1.1.0 or 1.0.0: a drop-in update. Just replace the jar: there are no new config keys and no world format changes, so worlds and settings carry over. Mixed 1.1.0/1.1.1 setups still connect, but update both client and server to get the full far-away effects.
• From 0.2.1: 1.0.0 was a full rewrite, and old worlds and configs upgrade automatically.
  • Placed Atomic Cores and Atomic Cores in chests and inventories carry over, and detonators keep their links.
  • Your old nukecraft-common.toml settings are imported into the new config files the first time they're created.

The black hole has been removed from NukeCoreCraft. It is being developed as a separate mod, SingularityCore, which hasn't been released yet. Any Singularity Cores or black holes in old worlds are removed when the world loads.

Requirements

• Minecraft 1.20.1, Forge 47+, Java 17.
• Oculus is optional.
• Install on both client and server for multiplayer. Singleplayer only needs the client. Works on dedicated servers.
