Caught by another in-game crash: "Entity is not resource." when
reading entity.amount. The previous fix (collision_mask: "resource")
was still wrong - collision layers and entity type are decoupled in
Factorio 2.0, so find_entities_filtered({collision_mask: "resource"})
can return non-resource entities that merely opted into the same
collision layer (likely something from Space Exploration or
Krastorio 2). entity.amount/initial_amount only exist on entities
whose prototype type is actually "resource".
Filtering by type: "resource" directly targets the right entities
and is simpler than inferring it via collision mask in the first
place.

Kafkatorio
Kafkatorio is a platform used for creating Factorio mods that require communication with an external server.
Development is ongoing.
At present Kafkatorio is used to create a live-view web map, that shows the current status of a Factorio server, and any connected players.
However, Kafkatorio can be used for more than this. It has the potential to export metrics, and allow for inter-server communication.
Kafkatorio was created to explore the possibilities of using Apache Kafka to process updates from a Factorio server.
Running
Instructions for running a Kafkatorio instance are available in the docs.
Overview
This is a brief overview of how Kafkatorio gathers data, processes it, and uses it to create the live web-map.
Kafkatorio receives updates from a Factorio server, processes them, and exposes them over a REST and WebSocket APIs.
-
The Kafkatorio game mod,
events-mod, collects event data, de-bouncing and grouping events, and converts them to JSON packets -
events-modprints the packets to the Factorio game server logs -
The Factorio logs are forwarded to a Kafka cluster, either using
- syslog (using Docker logging plugin)
- or Kafka Pipe (a script that reads the server logs and forwards them to a Kafka topic)
-
The packets are consumed by
events-server, which processes the packets using Kafka Streams, creating and hosting map tiles.events-serverserves the map tiles via a REST API, and produces WebSocket messages regarding updates (for example, when a player's location has changed). -
The
web-mapuses Leaflet/JS to display the map, using the tiles and WebSocket messages fromevents-server
