Calypso's Mobs
by YurisCat
Calypso's Mobs adds a small set of creatures for Fabric, Forge and NeoForge, with one fiery helper that works as a disguised furnace.
What it does
The creatures are described as cute and useful, and each one is meant to do a specific job in the world. The fiery helper, the one mob the author calls out, looks like an ordinary furnace until it wakes, and it can pick up smeltable items lying on the ground, smelt them without any fuel and spit out the results.
The helper heats up over time, which speeds up smelting, and cools down when it sits idle. At night it falls asleep, and a smeltable item held nearby wakes it up. The mod began as a project to learn creature AI, and the author plans to build further mods on what was learned.
Installation needs Fabric Language Kotlin, Geckolib, Kotlin for Forge and SmartBrainLib as required dependencies. Every player and the server need a copy of the mod. Files cover 1.20.1, 1.21 and 1.21.1 for Fabric, Forge and NeoForge, and the code is under the Apache License 2.0, which makes the project open source.
Key features
Smelting helper
The fiery helper picks up smeltable items from the ground and smelts them automatically, with no fuel needed.
Heat-based speed
The helper warms up over time, and smelting goes faster while it stays hot, then it cools down when idle.
Disguised furnace
The creature looks like a regular furnace, and it wakes when a smeltable item is held nearby.
Crafting recipes
The helper can be crafted with either of two recipes, so players can pick the route that suits them.
