Hi there, fifth anniversary for the Friday Facts is here. Nothing big, but we got into the mood of doing these updates regularly and so far it works fine. The release clock has stopped on 0.7.4. This looks pretty stable though there were still some minor annoyances and rare crashes. So the show goes on and there will be a 0.7.5. That will make the 0.7 a release with most bugfix subreleases so far. Actually Kovarex took it as sort of a challenge to fix all the bugs that are reported on our forum (which works as a kind of bug tracker for us). Now there are last four. Actually this led us to a rather interesting conversation about the bugs and our approach towards them. We have always took the stance of fixing bugs first, adding features later. This is contrary to some very popular and successful indie games out there. So we naturally wondered whether it makes sense for us to keep doing this or whether we should try to move forward faster and build more features (there is plenty on the list). The conclusion was that it is important to find a balance. Crashes and bugs which prevent someone from playing or are annoying are not tolerable and must be fixed immediately. However we will be spending less time on tiny little bugs. Things like "if you are in the god mode and select a gun turret and pause the game and open the menu, then the description of the gun turret is broken". Obviously a made up example to demonstrate the point:). We are really grateful that people are reporting even the smallest bugs, it's just that we think we need to draw a line and don't be afraid to say "this is tolerable now and we will fix it later". This will allow us to spend more time with the new features and content. Which is what we really need at the moment. On the side note the work on the trailer is in the full speed. As mentioned before we have decided to go for a not so traditional approach without scene cuts. So the trailer will basically present an existing factory by sliding the camera from one place to another. The factory is done. Actually I took the factory from one of my freeplay games and adjusted it to fit the trailer's needs. Now we work on the script logic behind it. The script controls everything. Movement around the factory, speed, zoom, dynamic adjustments to particular machines, timing of actions, etc. This is also positive because it led us to extending the Lua API - for instance we have added routines to control the trains. These changes will be available in the 0.8 together with the trailer map and the script. There is still a lot of work ahead - finishing the script, balancing the speed and flow, polishing. After all this is done we will just press a button and capture the trailer from the screen. Lastly we will need a background music and sound. We haven't arranged anything yet, but Albert has some good contacts among sound professionals who could do this for us. There probably will be some spoiler discussions regarding the trailer on our forums soon. For the impatient there is a screen shot of a possible first trailer scene below (still needs some polishing - namely new terrain and additional decorative objects). There is a link on our forum to this blog post so feel free to share your comments. To finish with the fun fact there is now over 7000 commits in the Factorio project repository. And counting.

Hi everyone, another week filled with bug fixing, technology sprites work and general small issues, has passed. Our internal wish to get the 0.12 stable before 0.12.10 release just flew by laughing merrily. But that will not stop us. Step by step we continue=) The Wedding The title says it all. Tomorrow is Kovarex's wedding day. The ceremony is going to take place in the countryside and we will stay at the venue till the next morning - afterparty, playing board games and stuff=). Kovarex is already at the spot doing some preparations but if there is a message you would like to leave him, you can use the comment thread on the forums . No Greenlight So there will be no Steam Greenlight. We were in touch with one of the Valve employees and they made us an offer to enter Steam directly without going through the Greenlight process. This is something that we will gladly do because that means less things to worry about (we have quite some of that already). Speaking about Steam. We have drawn quite good inspiration from community forum discussions following past Friday Facts episodes. Namely the ones regarding when to enter Steam and how to promote the game . So as for entering the Steam, we have settled to aim for January 2016. As usual this is a plan and plans can change (especially when it comes to Factorio release announcements=)). Gameplay preview Regarding game promotion, we have decided to give it a shot and create a gameplay footage / preview video. Basically it would be a short (less than 2 minutes) video that shows basic game mechanics and how the game is played. If the trailer gives a taste of Factorio (and it is a first video we expect potential player to see) this gameplay preview should be the 2nd video and it will give him a "glimpse on the menu". At the moment we are in the planning stage but we will make sure to keep you up updated. Also we are getting in touch with some professional (Indie) game promoters to see if we could work together and give more shine to Factorio Steam release. If you have more recommendations regarding our planned Steam launch please share them (ideally on the forums). It is a great source of inspiration for us. Community spotlight I would like to start a new section here in the Friday Facts when we ocasionally introduce interesting content from the community. The thing is that the Factorio community-generated content (mods, youtube videos, tools, suggestions and tutorials) is getting quite big and it might be of a good value to people who are not up to date with what is happening. It will of course be biased by our preference=) So here we go. For today I would like to mention an interesting video series made by Negative Root. Negative Root is very active Youtuber with quite some Factorio content. What I especially like is the variety in the content he produces. He has an extensive tutorial series (also higly recommended), break the game series, couple of regular Lets plays etc. The one I have chosen for today is his Factorio Fixit series. So the idea is that Root Negative "visits" other people's factories, inspects them, improves them and also gives ideas on how to do things more efficiently. And this whole process is recorded. Something like Factorio public consulting. Root Negative has played the game a lot (a LOT). So he has quite some experience to share (judging from the videos much more than me for instance :D). Making a series like this gives a great value for the person who made that factory as well as for general audience who is interested in improving their factory building skills. The series has been running for a long time so there is plenty of "study material" there. Below is a recent episode where he is dealing with building blue science setup. Team update On monday, Vaclav has reinforced our GFX team as we have announced in the past. So we are now 10 people sitting at the office. Actually, yesterday we went to take a few photos of the team. The team page update is coming soon. Stay tuned. That is it for today. The commenting thread is where you expect it .

Hello, we spent one whole day by playtesting the 0.12 multiplayer. To my surprise, we didn't encounter any problems so we are just few small bugfixes far from the 0.12.23 which will be probably the version used on steam. I thought how experienced and good we are when we managed to make pretty big factory in just 8 hours, but once I saw the Factorio world record speedrun I don't think so any more :)

A week in the office This week is another week of typical bug fixing, so I thought we would make a one-time change of style and do a day-by-day account of what exactly that means for us.

Hello, this week the Friday Facts are coming a little bit earlier. The reason is that in the evening I will be lost somewhere in the middle of Brno (second biggest city in the Czech Republic). I will participate in a popular annual deciphering game that is taking a place there. The 0.7.5 with another batch of bugfixes went out this Tuesday. Since then there has been no reports regarding major issues or crashes. Couple of teeny-tiny bugs were reported however that is not enough for us to make a new release now. So the 0.7.5 will become a stable version. Finally:) I have spent most of the time during the past week working on the trailer. The first version has been done already. There is a discussion thread on our forum (with a link to the unlisted video on youtube) where people can give us feedback about it. This is by far not finished. But we needed to get it out in order to start talking to the music & sound guy and give him some baseline to work with. Yesterday we had a long chat with Albert about the trailer and we agreed that the first scene (standing in the middle of the ruins) should be changed. Now it feels too out of the context from the rest. Apart from that we are quite happy with the general flow. Of course there are plenty of details that need to be tweaked so there is still a long way to go. On the other hand having all the trailer in the script makes things a hell lot easier for us. Changing things like the zoom behavior, camera movement or speed is just a breeze. Same goes for extending / shortening the scenes or adding a new scene all together. Another issue is the final video quality. There is a lot of movement going on in the trailer and currently after youtube compression, often the video is just blurry. We have used the 720p for now but that proved not to be enough. Oh and regarding the music. Just for fun we tried to run the Raymond Scott's Twilight in Turkey together with the trailer. It turned out to work surprisingly well, so one option is that the music would go in this kind of direction. Apart from preparing the 0.7.5 Michal spent most of the time on the new scenarios for the main campaign. It starts to slowly shape. At the moment there are 5 levels that introduce basic things like assembling machines, research, trains, etc. to the player in the course of playing. Often the player is not starting from the scratch but he can use already existing pieces of the factory. Writing the scenarios (and the trailer) is also a good opportunity for us to review, document and extend the Lua API. Kuba and Albert keep working together on the terrain. There are couple of variations of the dirt by now and Albert is now spending his evenings with the grassy terrain. Kuba made couple of Blender scripts to ease the manual terrain work. This way Albert can take advantage of generated tileable noise or terrain transitions. Also yesterday Kuba showed me a great picture he generated that I can't resist to share with you. In case that you always thought that there is a lot of recipes in the game and that the whole thing is too complex, then worry no more. Here is an ultimate Factorio recipe cheatsheet for you: As usual there is a post on our forum where you can discuss this update.

Good evening Factorians, today we had a presentation about the game at one of the universities here in Prague for the subject called "Video game development". It was focused on what is it like to develop an indie game. So yesterday we spent some time reflecting the past year and a half to come up with topics to talk about. We were thinking a lot about the period about a year ago before the Indiegogo campaign started, when the game was completely unknown to the public and we were close to burning out. The positive finding wat that as opposed to that period the work is now much less stressful and generally enjoyable. Maybe we (and people in general) should think about our down moments more often to better appreciate what we have ... Last Friday Facts promised a stable 0.8 release in the beginning of this week. Well, that was a false promise because couple of more bugs have been found that resulted in the new record for number of bugfix releases. Now we have the 0.8.8 in the experimental stage. If there are no serious issues found this will be made stable during the weekend. Having so many bugfix releases is rather annoying (and we plan to improve here by starting with automated testing) but it doesn't slow us down in the regular development. We have multiple development branches and the work on the 0.9 has been going for a while in the master branch, while the bugfixes are collected in the current release branch (the 0.8.x) and then merged back into the master. Talking about the 0.9, the work has been progressing well. Quite some internal rework of concepts is required for the oil industry and fluids in general. However, yesterday we already had an assembling machine that makes a recipe from some items and water supplied by the pipe. For this to work the recipe mechanism has been generalized and in the end (not yet done) following will be possible: The recipe ingredient can be a fluid. The recipe can have multiple results (both items and fluids). The results of the recipe can be randomized (there will be a probability of getting the result and a min - max range for the amount of the result). There might not be much more fluid content aside from the oil (and its variations) in the 0.9, however the mechanisms will be there for the modders to play with and take advantage of them. And we are curious what they come up with:) Kovarex has been working on the native blueprints for some time and he has the core functionality more or less finished. Of course that is just a small portion of the total work required (polishing, bugfixing, integration with other concepts, etc.) but it is something that can already be played with in the 0.9 branch. And it is actually quite fun to play with. The system is relatively straightforward now: You make the blueprint item. You select what to store in it (you get the blueprint preview on the item afterwards). You place it and the construction robots build it. You can check it out on the mini picture series below, where blueprints have been used to build the standard furnace line. If you would like to share your thoughts or ideas about this post, you can do so on our forum.

Hello, today the Factorio Friday Facts turn 18. That is considered an age of maturity in many countries. So the glass of Jagermeister on my desk is completely justified :) The time here in Prague feels just like whooshing around us faster and faster with the end of January approaching rapidly. That was the original estimate for the release of 0.9 but now it seems that it will take a week or two more. The usual "everything takes longer than expected" has applied this time as well. The current development version has placeholders for some new entities (like a plain rectangle box saying "oil refinery" or another one with "chemical plant") and we really want to make proper graphics for these and deliver the basics of new oil content as a whole package. Recently we got a bug report claiming that the game is too slow. The guy who posted it was right, the game was running well under 60fps. In our defence it needs to be added that his factory was pretty monstrous. It was actually the biggest one we have seen by far. Just to get an idea, his factory had 9000 solar panels, 15 000 laser turrets and thousands of logistic robots. So kovarex took it as a challenge to squeeze as much performance from the engine as possible taking this save as a reference. He has been working on it for the past couple of days. The most significant optimizations he made are: Efficient dispatch of pending logistic robots. This was probably the cause of the biggest slowdown in the given save. Wake-on-demand mechanism for inserters. Until now the inserters always asked every tick the objects in front of / behind itself whether they should transfer anything. Now, instead they put themselves to sleep and the object wakes them up when its state changes (that means there is a chance a transfer will be required). Improved cache locality for the electric energy network. The result: game update dropped from roughly 30 milliseconds per 1 update to about 10 milliseconds (and there is more to come). Of course not everybody will get this amount of performance improvement (the optimizations are aiming at the game update for big factories). But in general this batch of improvements pushes the bar for the size of the factory further up. The work on the oil industry has entered the last phase. The fluid and recipe mechanisms as well as new entities are ready and now it is all about adding the actual content. I have been studying the oil refining process quite a bit recently and also I took this opportunity to refresh some bits from my high school chemistry curriculum. The way it shapes now the oil industry will be a middle to late game resource. Its usage will start somewhere between the green and blue science pack and its products will cover a variety of areas (fuel, plastics, lubricants, explosives, etc.). There has been quite some discussion about the oil industry on the forums. If you are interested and want to contribute your opinion you can do so in this thread for instance. Kuba and Albert have been working together a bit on the integration of the new doo-dads into the map generator. The goal is to approach the scenery compositions shown in the previous posts . Though that is difficult (because those compositions are hand made and imho very good) the doo-dads should greatly improve the current flatness of the landscape anyway. On top of this Kuba has been busy with a neat feature when the game will natively treat zip archives as directories (so the saves / mods can be zip packages). And of course Albert's table is full of "oily stuff" - now comes the interesting part - the oil mining drill, the oil refinery and the chemical plant. Today's picture is a glimpse into the internals of Factorio. The screenshot shows a diagram of entities' (objects on the map) class inheritance structure generated by doxygen. If you feel like expressing your opinion regarding anything above then go ahead and do so on our forum.

Hello everyone, even though it is not Friday anymore here we come with yet another regular update. We didn't want to make a blogpost on Friday the 13th because for sure something would go wrong. And also I am on a skiing trip in Austria and I was too tired yesterday to do anything, after all the day going downhills. So the 0.8.0 has been succesfully released last Friday. We finished at the same time when first guests for the party started coming. We just crossed our fingers, pressed the release button (maybe we should have a real, big, red "release" button) and went off to drink beer and talk to people. The cake (see the picture in the last post) was delicious:) Back to the release - there were small issues, but nothing really major ("Pump cannot be built" kind of thing). We have already fixed most of the reported issues for the 0.8.1, which will happen in the beginning of the next week. We haven't worked on anything major aside from the issues. We took the time to relax after the intensive release sprint (says the guy who has been skiing all day long:). Kovarex was playing some games (including classics like Dune 2000) looking for inspiration. There was also a long conversation about how the new industry with oil and chemicals should work. Interesting things ahead. Originally we wanted to start the Steam Greenlight campaign before the Christmas. Now it is clear that this will not happen. The reason is that the music for the new trailer is not yet ready. The cooperation with the guy we hired for the music hasn't brought the expected result. So we are back where we started. Recently, we found a composer in Prague, who looks like a very good fit for the job, but he will not have time until after Christmas. At least Albert will have more time to work on doodads for the game (and the trailer) - things like trees, rocks, etc. Albert also took the opportunity to work on something completely different for a while and he came up with a proposal for the new Factorio logo. The old (current) logo has been done by me and then face-lifted by another artist. But still it looks painfully amateurish. The new logo doesn't have that problem:) Together with the logo Albert worked on the new forum style, this will be deployed sometimes next week. So here is the thing. We actually have two proposals for the logo. And we would appreciate some help and opinions for deciding which one to use. You can see the proposals below. They are shown on the potential loading screen of the game. We do have our preference but will not say which one that is to avoid influencing the outcome. They both work as links for larger versions. There are polls for you to vote and comment in the post on our forums, so go there and let us know what you think.

Hello, another friday and another Facts. It has been 3 years already without a single friday facts missing. I didn't expect that!

Good afternoon, the week in the office has been relatively quiet. The whole non-dev department is away, kovarex is flying his paraglide somewhere over Macedonia so in the end there is like 6 of us meeting here to make the game crash less often=)
