Calypso's Mobs

🧪 A small mod with potential to grow

We’re learning creature AI by developing this mod.
At this moment, it features just one mob—a fiery little helper you’ll definitely want to meet.

Required Dependencies: GeckoLib | Kotlin for Forge | SmartBrainLib


🔥 Furnace Sprite

Summon Furnace Sprite

A cute, animated sprite disguised as a furnace.
It smelts nearby items automatically—no fuel required.


🛠️ Crafting

You can craft it with either of these recipes:

Crafting A Crafting B


⚙️ How It Works

Furnace Sprite picks up item

  • Picks up smeltable items on the ground
  • Smelts them automatically
  • Spits out the results

Furnace Sprite burns faster and faster

  • Heats up over time for faster smelting
  • Cools down when idle

🌙 Day & Night Behavior

Furnace Sprite falls asleep

  • At night, it falls asleep if idle
  • Disguises itself as a regular furnace

Furnace Sprite wakes up

  • Holding a smeltable item nearby will wake it up!
  • Or… you could just give it a gentle tap

🧪 More to Come…

This mod began as a small project to help us learn creature AI.
As we grow, we’ll use what we’ve learned to create even more exciting and creative mods in the future.
