Gray Goo
by Jaggwagg
Gray Goo adds a destructive nanite block to Fabric worlds: placed blocks spread across the world and crumble what they touch, and nanite modifiers change how the goo behaves.
What it does
Gray Goo is a technology mod that adds a titular block which, once placed, replicates through the surrounding world and breaks down existing blocks. Players can customize the goo with nanite modifiers that give it different traits. The mod requires Fabric API and runs on Fabric 1.19.2 – 1.20.2, with builds for 1.19.2, 1.19.3, 1.19.4, 1.20.1 and 1.20.2. It is released under the MIT License and is open source.
Key features
Self-replicating goo block
The goo block spreads from where it is placed and converts the blocks it reaches, so a world can be taken apart over time.
Nanite modifiers
Nanite modifiers are added to the goo and alter its traits, letting players set how the spread behaves.
Modifiable traits
Traits can be added to or changed on the goo after placement, so the same block can be configured in different ways.
