Hungry Waters
Beware the waters... Piranhas have arrived!
Overview
This mod introduces a new fish entity: the piranha. A school of piranhas will spawn randomly in either swamp biomes, or river biomes. Piranhas have a hunger bar which goes down over time, then they enter hunting mode and will attack anything near them to refill their hunger bar.
Features
- Piranha custom entity
- Piranha have a hunger bar, when it reaches zero, they will enter into hunting mode and start hunting anything alive nearby (including you)
- Piranhas will fight back when attacked
- Piranhas will only spawn in river or swamp water biomes.
Configuration
The mod includes a config file allowing you to tweak many things!
Datapack
Spawn frequency and school size can be customized via datapack, as these values are loaded from a biome modifier file.
