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
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:
⚙️ How It Works
- Picks up smeltable items on the ground
- Smelts them automatically
- Spits out the results
- Heats up over time for faster smelting
- Cools down when idle
🌙 Day & Night Behavior
- At night, it falls asleep if idle
- Disguises itself as a regular furnace
- 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.
Special thanks to my friend @wmmzkl for the congratulatory illustration.
