The much-anticipated Steam and Itch.io model of Dwarf Fortress was introduced in 2019, and brothers Tarn and Zach Adams saved engaged on the sport till its launch final December. However it was precisely two years after the unique announcement that Putnam — a developer who has been concerned locally for round 10 years now engaged on common mods and reverse engineering the sport — despatched Tarn a decisive e mail.
“We knew simply from our Steam want checklist numbers that our sport was going to do fairly nicely,” says Tarn in a Zoom name as he searches for Putnam’s e mail in his inbox. “Then we requested ourselves: ‘will we wish to carry another person?’ It wasn’t even one thing we may contemplate earlier than in a standard capability.”
Across the starting of 2022, the group began to publicly talk about the potential of hiring a brand new programmer throughout interviews. Earlier than then, Tarn says that one choice was to open supply the sport. However after seeing the want checklist numbers enhance over time — culminating in over 1,000,000 through the month of launch — they thought they might preserve the supply code closed up and share it with a brand new group member as an alternative.
“I used to be having a nasty day or one thing and simply rambled about how having one other programmer may take time away from the sport and even make it much less their product,” Putnam says, “and that appeared unlucky to me. I rambled about that for some time, after which I believed, but additionally, in the event you’re going to rent a programmer, I’m an choice. Huh. That’s how I ended that, and that half appeared to have caught, in order that’s good,” she provides in laughter.
Certainly one of Putnam’s greatest early objectives was to make it as painless as potential for her to be engaged on this sport out of respect for what Dwarf Fortress is, each as a sport and as the results of the peculiar work dynamic of the Adams brothers over so a few years. But, she was assured that she could be as much as the duty. In any case, she found the venture again in her highschool years as she looked for one thing that wasn’t instantly recognizable as a sport and which may match on a thumbnail for her to slack off after she completed her math and typing class assignments. The ASCII graphics of the traditional model had been good for this.

The programmer, who is nearly 28 years previous now, first started enjoying Journey mode. Over time, she started toying with the modding system, which appeared a bit restricted for a few of the concepts she had in thoughts. Utilizing exterior instruments allowed her to hack the reminiscence of the sport and opened the room to extra prospects.
“It stopped being ‘how can I do what I wish to on this system?’ and extra ‘how can I do what no one else has accomplished but on this system?’” Putnam says. She had round a 12 months or two of programming expertise by the point she began doing mods, and it has develop into her profession since. “I saved looking for: ‘can I do that? Yeah, seems I can.’ And it saved occurring time and again. And I acquired actually into that, and within the course of, I occurred to be taught much more concerning the sport than most individuals ever realized.”
It’s been round a month because the second programmer joined Bay 12 Video games. For Tarn, that is an unprecedented occasion, breaking a 16-year-old custom of being the only real individual working within the Dwarf Fortress code. It comes as the sport is now extra common than ever — it offered virtually half 1,000,000 copies in December, and it’s presently sitting at an “Overwhelmingly Optimistic” score on Steam, with over 17,000 critiques by the point of publication.
“There are some actually gnarly issues that we haven’t needed to undergo but”
“Overwhelming is about the proper phrase, I assume, as a result of I’m technically overwhelmed,” Tarn tells me. “We haven’t mounted as a lot as I might have preferred by now, and that’s not anyone’s fault. There’s simply an excessive amount of occurring. Having me as the person who’s doing all this media stuff, and likewise doing the programming up till three weeks in the past, it wasn’t one thing that was going to result in numerous patches. That’s simply not the way it was going to be. However now, I acquired numerous good fixes developing, and that’s all Putnam.”
There hasn’t been a lot of an onboarding course of. Opposite to what I initially thought, Putnam didn’t obtain a newbie’s information to understanding Tarn’s code — she picked most of it up from disassembling the sport throughout her modding years. Earlier than Tarn knew it, Putnam was already caring for what he says is a protracted to-do checklist of bugs to sort out.

Now, Putnam has entry to the supply code and is ready to undergo stuff on her personal. The group has arrange a model management system — which permits programmers to simply arrange completely different branches to report adjustments individually from one another — and is presently engaged on Easy DirectMedia Layer 2, which is an improve to the present model in preparation for the Linux and Mac ports.
Tarn admits that whereas Putnam hasn’t had many issues understanding the code, there positively are some bits and items that can require time to parse via. “I haven’t seen some issues for 10 years. So I’ve some remarks in there that are actually useful for the opposite individual as nicely. However there are some actually gnarly issues that we haven’t needed to undergo but. We haven’t acquired into a few of the map technology code that’s simply type of disgusting,” he laughs. “However of the issues that [Putnam has] checked out thus far, there hasn’t been numerous bother.”
“It’s a miracle that it runs higher than The Sims 3.”
Attending to the purpose of understanding Dwarf Fortress’ logic, particularly with what number of intertwining calculations are operating within the background always, was a course of that took Putnam a very long time. Whilst an lively member of the neighborhood, she doesn’t suppose that anybody actually is aware of how every thing interacts. But when somebody fragments the sport into small items, studying how these particular person components work is an effective methodology to not be fully overwhelmed. In a method, not likely having the ability to know every thing is the explanation why it’s nonetheless enjoyable to play the sport, even when you understand lots about it.
Putnam says that it’s widespread for open-source tasks to go for utilizing a standardized code format. Even when that’s not the case for Dwarf Fortress, she nonetheless finds it simple sufficient. “It’s only one man’s code. It’s very constant. Individuals ask me how dangerous the code is, and I don’t know what they imply by this,” she laughs. Algorithmically, the sport is “fairly nicely optimized” and she or he doesn’t appear to suppose there are large adjustments that might be accomplished. “Dwarf Fortress simply does extra calculations than the overwhelming majority of video games. It’s a miracle that it runs higher than The Sims 3.”
If something, accessing the supply code has allowed the brand new programmer to replace the sport’s in depth wiki with extra correct details about a few of the clues from the neighborhood, considered one of which is an inventory of strategies to maximise body fee and enhance efficiency. Whereas the wiki entry is fairly damning in opposition to pathfinding as the principle issue, Putnam says that there are different components concerned, corresponding to dwarves taking a look at one another and doing the calculation to determine in the event that they’re associates or foes.
“Pathfinding is sluggish,” she explains. “And if it’s occurring lots, your sport will decelerate right into a crawl. However it doesn’t occur lots. That’s the factor. Pathfinding isn’t even a 3rd as necessary as simply everybody wanting round and seeing if there’s anybody close by for them to beat up or hug.” The neighborhood found out that constructing star-shaped staircases improved efficiency, however as Putnam says, it’s as a result of the partitions break the road of sight, so characters can’t see dwarves which might be 20 steps down and aren’t compelled to run the calculation to determine whether or not they’re their mother or a rival.
A latest optimization replace tried to make it in order that dwarves who’re lifeless, caged, offside, or a ghost aren’t concerned in any of those checks. However the checks had been nonetheless occurring, as the sport had to determine whether or not the dwarves match into any of these 4 classes both method. “That’s the type of factor you wish to decrease, it seems, and the trick to reduce that’s fully alien stuff that the neighborhood by no means picked up on,” she says.

Tarn says that he’s at all times been afraid of any person wanting on the sport’s code and discovering one thing horrifying in there. Despite the fact that he’s not so anxious about it now, he thinks he was extra sensitive concerning the thought a while in the past — not simply due to the prospect of coping with completely different programming types, a side by which, fortuitously, he and Putnam have lots in widespread, but additionally due to how argumentative folks could be on-line.
“Individuals could be nasty typically about these issues, and I simply didn’t wish to take care of that,” he says. “However that’s not the vibe right here, so it’s high-quality. It’s simply going to be humorous after we discover stuff that Putnam doesn’t wish to take care of … We already hit one thing like that — there was this gnarly line, and I used to be similar to, ‘Yeah, I should have been drained.’ I imply, you may’t be programming for a very long time and anticipate every thing to be nice-looking. It’s simply not the way it works. That’s why we have now so many bugs in so many video games, proper? We’re all human.”
Even earlier than the addition of Putnam, Bay 12 Video games had stopped being the duo’s unique venture years in the past due to the involvement of artists, music composers, Kitfox Video games as a writer, and most lately, the content material creator SalfordSal.
Future steps contain including Enviornment mode quickly in addition to persevering with to sort out bugs and ending the Linux and Mac ports. From there, Journey mode is the massive focus, for which the group is bringing on extra folks for graphics, audio, and so forth. Tarn is hoping to have the mode up and operating this 12 months however stays uncertain in the meanwhile. He additionally mentions that hiring a QA tester wouldn’t precisely work as a result of nature of the sport, as one small change would require them to check every thing associated to it, and there wouldn’t be sufficient time. Nevertheless, the group is envisioning choices that different video games have accomplished, corresponding to organising a public experimental department for folks to supply suggestions earlier than the replace formally rolls in. “I feel Dwarf Fortress remains to be going to go ahead at about the identical fee and have the identical type of options added,” Tarn says. “Each step simply entails extra folks.”
“Attending to work occurred sooner than I may have anticipated”
He explains that whereas the Steam and Itch model was a giant launch, and there’s a sense that the group may proceed to develop, the discharge was a one-time occasion. There received’t be sequels or DLC. The momentum that came about in December is the inspiration to assist plans that span throughout years sooner or later, which embrace options corresponding to villains, armies, and magic. “We simply must watch out about shedding off the launch lump as a result of that’s all we get. We don’t wish to be considered one of these tech corporations this month [saying] we’re now shedding 8, 10, 12 p.c of our workforce as a result of we couldn’t handle our numbers accurately or some shareholder mentioned some nonsense or no matter. So we’re simply being cautious.”
Putnam is obvious about every thing she brings to the desk, from her concentrate on optimization with fashionable CPUs in thoughts to methods by which she will enhance productiveness for the group on the whole. But, no less than for the time being, she tries to not step on anybody’s toes.
“If I needed to undergo the interview query ‘why do you suppose you’re the very best match for this position?’ I might have mentioned it’s as a result of I already know do all these items,” she says. “My primary concern right here is to see how painless I could make together with one other programmer within the improvement course of whereas rising productiveness by way of bug fixes and optimization. That has been, and nonetheless is, my precedence. Attending to work occurred sooner than I may have anticipated, which is nice, and there was productive work on all sides now, and I haven’t gotten in the way in which. I hope I haven’t gotten in the way in which that a lot,” Putnam laughs.
“I feel having somebody who understands and could be very protecting of the character of the sport, that’s simply going to be pretty much as good as it may be, proper?” Tarn provides. “And I don’t know if there’s ever going to be bother with the tone of the sport. We’ll get to that as we undergo it, however I feel we’re in the very best fingers we might be.”
