Volcano Mod
I wanted to make mountains grow. Most structure mods just paste a building into the world instantly. I wanted something more dynamic—a mod that lets you watch a massive volcano rise out of the flat ground in real-time.
How it works
It’s a mix of terrain deformation and a chaotic event.
- It Grows: When you start the event, the ground actually rises. It pulls the terrain up to 100 blocks high, converting the dirt and stone into jagged Basalt as it goes.
- The Eruption: Once it hits peak height, the crater fills with lava and starts spewing smoke and particles.
- Volcanic Bombs: It shoots magma projectiles into the sky.
The "Smart" Destruction
I spent some time tuning the destruction logic because I didn't want the volcano to blow itself up immediately.
- Near the Crater: Explosions here are visual-only. This keeps the volcano looking cool and pointy.
- Further Away: The projectiles cause real damage and set fires. It creates a nice zone of chaos around the base without ruining the mountain itself.
How to use it
Right now, it's trigger-based (great for admins or people who just want to see the world burn).
- Find a big open space (seriously, you need room).
- Run:
/volcano activate - Stand back.
Performance Note
Since this mod is actively moving thousands of blocks to create the mountain shape, it can be a bit heavy on the server while it's rising. Don't spawn this next to your base. It will eat your house.
Enjoy the eruption!
