Supernova (Inspired by OuterWilds)

I built a supernova in minecraft. Over time the sun will get bigger and bigger, then eventually go supernova like in OuterWilds. I did vibecode this with Claude

Description

My first mod inspired by OuterWilds :)

(Claude AI was used to make this)

☀️ Supernova

The sun has 22 minutes left.

The moment you load your world, the sun begins to die. Over 22 real-time minutes it swells into a burning red giant, scorches the land, collapses in on itself, and explodes in a supernova that sweeps across the world.

There’s no time loop and no second chance. When it’s gone, it’s gone.

Inspired by Outer Wilds.

🔥 The Last 22 Minutes

Time	What happens
00:00	A normal sun. Enjoy it while it lasts.
03:00 - 14:00	The sun slowly grows, its surface churns, and sunspots begin to appear.
14:00	It swells into a red giant and the whole sky turns red.
16:00	The heat builds. Snow and ice melt, flowers wither, grass dies, and water evaporates.
19:00	Direct sunlight now sets you on fire. Find shade.
20:00	The sun becomes unstable, pulsing and flickering while distant rumbles grow louder.
21:30	It collapses into a single blinding point and the world goes dark.
21:45	SUPERNOVA. A flash, a heartbeat, then a wall of blue-white light rushing towards you.
22:00	The shockwave hits. Everything under the open sky is vaporised and the land is scorched.
After	Eternal night under a tiny neutron star. Mobs roam a world that will never see daylight again.

✨ Features

A sun you can always see. It stays fixed in the sky for the whole sequence, so you can watch it age.
Custom pixel-art sun textures that age gradually from yellow, to orange, to a deep red giant, to the final blast.
A sky that changes with it: the sky, fog and clouds turn red, darken during the collapse, and turn blinding white in the blast.
A world that reacts: melting snow, dying plants, evaporating water, burning players and a scorched surface.
Sound design: rumbles, a collapse, heartbeats and the blast.
Survive it, or don’t. Shelter underground and you might make it through the shockwave. The world you come back to will be very different.

🛠️ Commands

These need cheats or op.

/supernova status: see where the timeline is
/supernova time <seconds>: jump to a moment, e.g. /supernova time 1260 for one minute before the collapse
/supernova speed <1-60>: fast-forward. /supernova speed 20 plays the whole thing in about a minute.
/supernova pause / /supernova resume
/supernova reset: bring back a normal sun and start again

💡 Tip: Watch it in Creative mode the first time, so you survive the shockwave and can take in the whole show.

📦 Requirements

Minecraft 1.21.1
Fabric Loader
Fabric API

Install it on both the client and the server.

⚠️ Note: this mod turns off the day/night cycle so the sun stays put. Use it in a world made for the experience, not your main survival world, unless you’re ready to lose it.
