Nuclear Bomb mod that adds a nuke to Minecraft with some pretty insane detonation visuals.
Features
Nuclear Bomb
- Right-click to place a 3D animated bomb on any block
- GeckoLib animated model with idle, armed, and critical states
- Beeping countdown that gets faster over time with smoke and sparks
Detonator
- Arms every placed bomb within 10,000 blocks
- Starts a 10-second fuse on all of them at once
Explosion
- 100 block radius destruction, processed async so your server doesn't die
- Three-zone terrain deformation — crater in the center, scorch ring around it, carved bowl floor
- Leaves behind blackstone and magma where the blast hit
- 10,000 HP damage at ground zero, less the further you are
- Knockback, fire, and radiation on everything nearby
Visuals (all client-side)
- Raymarched mushroom cloud using custom GLSL shaders with depth occlusion
- Screen flash goes white → orange → red
- Camera shake has two layers: a fast jolt and a slow rumble
- Six-phase particle system with ground fire, secondary blasts, heat embers, base surge dust, suction vortex, and ash fallout
- None of this touches the server — it's all rendered on client
Radiation
- Custom mob effect that does more damage the closer you were
- Lasts up to 10 minutes near ground zero
- Higher amplifier means faster damage ticks
Requirements
- Minecraft 1.21.1
- NeoForge 21.1.219+
- GeckoLib 4.7.5.1
Notes
- Works in singleplayer and multiplayer
- Block removal is spread across ticks so it won't freeze your server
- You can detonate multiple bombs at the same time
