Not certain why the blueprint string didn't work, so here's a hopefully working link instead

Here's an easily-tileable 11 segment display using far fewer combinators: This works by exploiting the fact that conditions on lamp can use "Anything = X" or "Everything != X" conditions, so the pair of constant combinators on the right specify a large set of values that -- when added to "N" -- will...

As commonly requested by participants of today's FactorioMMO Stress Test: While waiting for a free map download slot while joining a multiplayer game, there should be some indication of your current position in the queue. Perhaps the text could read "Position in queue: 36 out of 205" or similar? Thi...

I meant in sense of the proposed QOL improvement presumably showing it, not as it currently stands.

Sounds reasonable. But why show the map exchange string at all when there can be a "copy map exchange string" button instead of a "show MES" button. No one is going to write it down character by character manually anyways, seeing it is always followed by copying it. Showing it means I also have to ...

Today's FactorioMMO stress test got me thinking on ways to handle truly massive scale multiplayer games with some degree of performance. One thought would be to have people split across multiple games with some form of sharing resources and chat between them. Some of this can already be done with ex...

But, the 0.17 implementation of landfill is clunky, mainly because you have to add landfill to the blueprint for it to work... Clunky. There is a mod that let's you add landfill to your older blueprints, but... you are still messing with the blueprints. BlueprintExtensions has had a rocky 0.4.x rel...

I'd also like to see this. I've one error report in particular where they only uploaded a partial factorio-current.log but it didn't have the first half which includes mod version numbers/etc. In that case, the issue was my mod relying on something added in 0.17.22 and them using it in an earlier ve...

TL;DR: Map exchange strings should be automatically copied and pasted when the relevant functions are accessed. 99% of the time, if you are looking at the map exchange string for a map it is because you are going to copy it and paste it somewhere else. Currently (in 0.17), this requires two clicks (...

on a side note, still waiting for the shift click build over water, hey robots can place landfill now, why can't they do with shift click method and also placing blueprints with shift click. Blueprint Extensions now has a "Add landfill to every tile of this blueprint that needs it" option, if you w...

So, 2 years ago I posted a request to have the GUI highlight matching items (and dim everything else out) when searching:

Yup, I'm aware that priority prototype bounding boxes are relative to the origin and facing north. Transformed bounding boxes can be obtained from an entity directly, but I don't have a real entity available in this case. The transformation itself is not too difficult though, I already have code for...

Second this.

Some entities (i.e. curved rails) have a secondary collision box. While this can be accessed on an entity itself (LuaEntity::secondary_bounding_box), it can't be accessed on entity prototypes. I'm working on a feature to automatically add landfill to tiles that need it in a blueprint, so this is nee...

After trying a bunch, I came up with something that sort of works but not entirely. So I'll post my write-up here and maybe it can serve as a foundation for someone else. Alright, here's a FIFO stacker. It took a bit longer than planned to complete since I had to resolve some issues where a train wo...

In the case of your parking bay, if you want a FIFO queue, wouldn't the easiest solution just be to use a long serial track as your parking instead of parallel ones? This has the drawback of extending travel time for a train that it wouldn't otherwise need when the queue is empty, and takes more sp...

It isn't so much "Trains are prioritized by ID number" as much "There is no natural prioritization of trains and all trains are evaluated in a deterministic order." Presumably, Factorio does not track when a train arrives in a station or maintain any sort of queue. This is not a bug, though it's not...

Addendum: I've noticed that there's a notable delay when moving blueprints into the library, which did not used to be noticeable in 0.16.x. Since I only opened the save for the the purpose of exporting the blueprint, the fact that I immediately loaded into the other save after the export (before it ...

I built a handy personal train station in one save, including a lot of complicated wagon filters. I figured I could export it to the blueprint library to dump into another save to avoid needing to tediously reconfigure of all the buffer chests and wagon filters, but my attempts at doing so seem to r...

When blueprinting a train on a diagonal rail, train wagons may not appear in the correct locations if the placed blueprint is near the original (or likely near other rails.)
