Dana: crafting tree/graph explorer

Status: Alpha / work in progress

Dana is an experimental assistant mod to help you understand the crafting graph of your vanilla/modded game. It is able to lookup for complete production chains, from raw materials to the most refined products (or the other way around), and display the result as a graph:

Incredibly impressive use of the rendering API!

Sadly the mod does not work in multiplayer at all:

Code: Select all

Please report this error to the mod author.

Thanks for testing and the bug report, I was able to reproduce.

It seems to be coming from me misunderstanding a part of the Lua API. If that's the case the fix should be pretty trivial. I just need to figure out migration scripts & Factorio changelogs to be able to release a proper v0.1.1 (which might take some time ...).

Truth be told I hadn't tested multiplayer until now, so it's probably a bugfest right now. Since I discovered that running a local server and multiple clients isn't rocket science, I should be able to stabilize it in the coming days. Maybe. Hopefully

UPDATE: fixed in 0.1.1 (freshly uploaded on the mod portal). I did some minimal testing on multiplayer and it seemed fine.
