I tried playing the game with a simulated 2 second latency link (120 ticks) and, well. I don't find it unplayable. Yes, inventory actions take 2 seconds to complete, but for most of the actions I could do the clicks and carry on knowing the action will be happen in 2 seconds. Walking around, placing...

Do you have any mods installed that could be responsible for creating a new world when you join? Is the map you download from the server the expected size? Does the playtime of the server match the playtime of the map in the server browser? Are there more than one surface in the map and you're joini...

Each efficiency 2 in a furnace reduces pollution by 0.1/m. Unfortunately, even with maximum efficiency 1s everywhere along the production chain, making that efficiency 2 module emits about 60 units of pollution. So it takes ten hours before the savings match the cost. Where do you get this number f...

What inspired the implementation of the auth server ban system?

I also want to hammer home that this site design (that's also shared with the main site, blog, mod portal and others) has the worst scroll lag I've ever experienced on a site with a mobile friendly layout on my mid range phone. I stopped reading FFFs on my phone because I'd rather not read the FFF t...

My first impressions to this was wow, why is it so visually noisy? Maybe it's something to get used to. My second impression was why is it so hard to read? The old one was something I'd describe as highly refined functionality over form to the point of beauty. Easy to read, easy to skim, just great....

After some discussion on the confusing workings of the yellow signal on the Technical Factorio discord it was pointed out that the Rail Signals Basics tutorial has this to say about the signal colours: signal-tutorial.png The problem with this description is that a signal into a block that is reserv...

A lot of events are described as "called when x happens", but it's really unclear what this means in isolation. For example the on_player_removed event is described as: "Called when a player is removed (deleted) from the game. [...]" Does this mean it's before the player is remov...

I see, I misunderstood how the authentication worked, I thought it was related to the server ID. Anyway what I noticed looking at the packet trace was that the second connection attempt was done with a new port on the client. So the previous NAT punch with established communication wouldn't be valid...

TL;DR Allow the names of servers in the public server list to be longer before getting chopped off. What ? Currently the limit for a server name is 50 bytes when encoded as UTF-8, and names longer than this limit is chopped off, I suggest increasing it to be much longer. Why ? Very few people seems...

Stevetrov encountered this desync removing and placing down an EEI on a server. Looks to be an issue with the active entity order. I managed to figure out a way to semi reliably reproduce it. Steps to reproduce 1. Paste the attached blueprint on a new server in the editor 2. Wait until it starts out...

Please provide the log file and what OS, hardware and version of Factorio you're running on for both the server and the client.

I've played with a 970 in 4k. From my experience I had noticeable frame rate drops when zooming all the way out with forests in view or when a lot of biter corpses were visible. Other than that it was fine.

Is the system clock on your server functioning and set to the right date and time?

The dedicated server server mode more or less ignores everything in config.ini expect for the paths so there's nothing useful in there. To make the whitelist work on startup there's 2 requirements, you need to pass --use-server-whitelist on the command line and the whitelist loaded (which defaults t...

I am eagerly awaiting Factorio 2.0 in 2029... not. But really though, game development is slow and you should all know what rushed game development results in by now.

It should not be workarounded (sending credentials without real need, security!), instead that problem should be fixed. User verification is a requirement for a server to be listed on the public server list. Connecting to public servers with user verification enabled requires the client sending the...

TL;DR Pass user verification on the first connection attempt to public servers. What ? When connecting to a server in the public servers list the client first tries to connect without the credentials that prove it's a verified user. But public servers have to have user verification enabled to be li...

I was curious how this graphics option updated on the fly, and tried to make the rendering resolution of lights increase. But no matter how much I switched between 0.25 and 1 at night I couldn't see any difference at all, even after restarting the game. So I started digging and found DrawEngine.cpp:...

And I think you don't understand how nat punching works. But the good news is that it actually functions in 0.16.51, so I've put together this demonstration video for you that shows the ping pong servers does relay nat punch requests contrary to what you're saying, and that this relaying is integral...
