Finorza

by decahedron

Finorza is a Fabric mod for Minecraft 1.16.5 that simulates autonomous agents inside the game world.

FabricClient-side onlyApache License 2.0Open source1.16.5

What it does

The mod starts a gRPC server inside the game, which lets an external agent observe the world and act on the player's behalf. Finorza is built for simulating autonomous agents in Minecraft, so research and experiments can run against a live game instead of a recorded one.

The project positions itself as a faster and cleaner, more customizable alternative to MineRL, though it is geared more toward inference and evaluation training than toward training from scratch. Most other optimization mods are reported to work alongside it, and one run was verified with Sodium, Lithium and LazyDFU installed together.

Finorza is published only for 1.16.5, with the 2.0.0 Fabric build dated 2024-02-18. Cloth Config API and Fabric API are required, and Mod Menu is optional. The mod runs on the client alone and is released under the Apache License 2.0, and its source code and issue tracker are public.

Key features

  1. Agent control over gRPC

    A gRPC server lets an external program read game state and send actions for the player.

  2. Autonomous agent simulation

    The mod is aimed at simulating autonomous agents that act inside a live Minecraft world.

  3. Customizable setup

    Finorza is presented as a customizable option for agent research, with its settings handled through Cloth Config.

  4. Optimization mod compatibility

    Sodium, Lithium and LazyDFU were tested together with the mod on a verified run, and the author notes that most other optimization mods are also reported to function alongside it.

Use cases

Agent research

Evaluation training

Training and evaluation of agents can run against the live game rather than a fixed dataset.

Who it’s for: Researchers and developers building autonomous agents for Minecraft 1.16.5 with Fabric will find the mod most relevant. Players who only want gameplay changes will not need it.

Questions

Which loader does Finorza need?

Finorza is published only for Fabric, so Fabric and Fabric API are required.

Does Finorza have to be installed on the server?

No. Only the player's game needs it, and servers run without it.

Does Finorza work with optimization mods?

Most other optimization mods are reported to work with it, and one run was verified with Sodium, Lithium and LazyDFU.
