Honestly, at 4:11, I think you might be misenvisioning what it is that a good chunk of people look forward to hearing about from you. I'd reckon a quarter or so of the people who've wishlisted the SES DLC on Steam originated from RUclips, stopping by on Steam primarily to support you and only secondarily because they want the DLC. And let's not forget that Patreon is a paid service. As is, there are undoubtedly plenty of people who would join the Patreon (and therefore have desires more aligned with the "Patreon" category on the diagram) if they could more comfortably afford it, but remain only within the "RUclips" and/or "Steam" category in practice. These are just two of the forces at play and there are plenty of other forces and counterforces I could list off, but the point is that you might want to reconsider what it really is that the different groups of people are really looking forward to. Especially your following on RUclips; it's common knowledge that just making videos doesn't cut it on this platform. There may even still be viewers whose only interest was 2D engine simulator and are holding out hope that the 3D version will be a cut-and-paste replacement for it! You do seem to have a good grip on the way you handle the different groups in practice, though. This video does a good job addressing a lot of points people might want to bring up on many different fronts, and paints a positive image of the progress made on the DLC. I suspect there'll be a lot of ES fans that won't watch it and several that'll click away halfway through, but for those who watch it in its entirety, I think they'll agree that your work on the DLC has been entirely justified and be satisfied with the video too.

I consider Steam to be a separate audience because there is an unexpectedly large lack of overlap between my audience on Steam and my audience on RUclips. A lot of the people who play Steam Engine Simulator actually don't know this channel exists and don't know who I am. It's surprising but true and I've analyzed this data extensively. Only about 2000 downloads of the base game originated from my RUclips channel initially. When the game went viral on Steam and was featured on the Steam home page, the game reached a significantly larger audience than even my RUclips channel could reach (over 100,000 players organically with almost no downloads originating from promotion on my channel). Again, it seems counterintuitive but it's true. Furthermore, while this is only anecdotal, most people I interact with on Steam and Discord about Steam Engine Simulator, clearly don't know who I am and found me purely through the Steam algorithm. In fact, almost everyone that arrives on Discord via Steam doesn't even know that Engine Simulator exists. It's for this reason that the priorities of this group are surprisingly different from the priorities of my RUclips and Patreon audiences. There is a large (but not complete) overlap between RUclips and Patreon audiences but the priorities are clearly different. A lot of my viewers are game developers or software engineers and don't actually care to interact with my products.

A battery would help with the difficulty. You could have a battery upgrade that is expensive and doesn't pay back for a while but it gives a bit more room for error when running the engine. The enhancements to the battery could get more inefficient as time goes on and the demand for power rises, while technically possible to run the city for days on battery only it would take so much time that people wouldn't ever use that method. It could also help with random events both positive and negative. If there is a drought or higher fuel price you could operate at a slight power deficit and use up battery charge until the water or fuel is stable again. Or maybe a lightning storm takes out some of your batteries forcing you to pay a higher cost to repair them. I think some kind of power storage could help with the balancing issue. At the very least it could be an optional thing for people to buy that might make the early game a bit simpler and I know some people would make challenges on how far they could get on battery storage as their main counter to energy demands. A battery would be very useful. I also think that it would make it more difficult to spiral into a negative account balance like so many testers seemed to do, if you could store power in a battery you could use that strategy. Let some energy from the battery out during the day when demand is higher and let it charge at night when demand is lower. You could also hold a battery charge and use it as an emergency tool! If something unexpected happens you could salvage the situation or reduce the damage by using the battery power. But if you rely too much on the battery then you could find that a problem or fault in your power storage could be devastating! I already mentioned a storm could take down the battery but what if the battery could catch fire? Or if you overcharge it could get damaged and possibly explode?! This would not only cost money to fix but it would also mean you'll lose all or most of the charge you accumulated, power that could have been sold directly for profit. Basically. The battery could add a risk vs reward mechanism. Where if managed properly could be helpful but if managed poorly could be very detrimental- and it could all technically be optional. As in you are never required to use the battery but you can if you want to.
What if you could operate the engine "inefficiently" producing excess power, but then you had the option to build power lines connecting to neighbor cities and sell them the exceeding power, like in Cities Skylines? (But only to a certain stress threshold where the engine would wear to fast and require too much maintenance to be profitable)
Using an AI to slowly transfer responsibility to the player is a great idea. Maybe the game should present the AI not as an AI, but as an elderly engineer who wants to retire, and is training the player to take over for them.
I probably should have made it more clear in the video but the AI engine controller is part of an actual NPC's AI, the mechanic I mentioned in the video. So your idea wasn't far off from what I was doing lol. Thanks for the suggestion!
13:10 When accounting for power generation, the higher amounts of power demands need to be weighted heavier. Under-producing power isn't an option, so the price has to lean towards the maximum, not the mean.
2:26 as someone who worked on nuclear power plants I kinda love this. It is incredibly hard work and we follow extremely strict SOPs set out by physicists for a reason. Heh while you didn’t set out to build a rage game. I think the difficulty is inherent to the subject matter and I like that your initial builds did not shy away from it.
That cable snapping event needs a lot of sparks lying all over the screen, with the cables continuing to spark as long as they are broken to really sell that something is not right.
I don't think you should worry about making a steam train simulator. To all the people who really want that, check out the in development game Century of Steam, which is a 3d narrow gauge railroading game that simulates realistic locomotive firing, operation, and railroad management. Give Ange some breathing room, let him finish this up and get to engine simulator.
@@lucchesi87 well the Patreons just gave him honest feedback on the game which he asked for. Ange wasn't frustrated, he was just not sure what to do since he has a heavy workload right now and has to choose what to prioritize. but that has NOTHING to do with the Patreons, they just did what he asked them to.
If they hated your game, they would be outraged at the turbofan test cell simulator I built years ago while working for Lockheed and Rolls-Royce at Stennis Space Center. I'm a former turbofan test engineer. Back in 2010 I designed and built a 6 screen stimulation, including a custom throttle, that simulated the testing of large jet engines. Specifically the Trent 9000, 1000, and XWB. The simulator had failures to test the crews reaction to problems as well as a playback of a real jet on our test stand that was synced to the simulated jet engine run condition. It was used to allow training of test crews without risk of damaging a real jet.
@@scottwatrous, it was interesting! I had a blast building and programming it for over six months. The test crews and other facilities also enjoyed using it. Better than destroying a 20+ million dollar R&D engine!
Yeah, when you're training to test 20 million dollar jet engines, and it's literally your job, the threshold for acceptable complexity and finesse is admittedly a whole lot higher than somebody who wants to have fun playing a little steam engine game for 20 minutes.
At 13:00: The average-value operator does not (in general) commute with a nonlinear function. This could be "fixed" by having price-by-demand simply be a linear function, but that would probably be boring. Instead, an effective but approximate solution would be to sample demand at several points during the day, take the price at those points, and average those samples. As long as demand isn't too spiky and the price-by-demand curve is smooth, that should be close enough to the true value.
That's basically it. The precise solution would be using calculus, though. You'll have to redefine average as taking an intergral and then dividing it by the period over which it was taken. Then you'll just take the average of the price as a function of demand, with demand being a predefined curve in this case.
You need to integrate two different things. First, you integrate demand * fair price vs demand to get a total price for the amount of power needed that day, then you divide by the total demand for the day (integration of demand).
yer AI gizmos might be handy later if you ever implement automatic transmissions or EFI in engine simulator, those are both effectively black boxes trying to optimize something by flipping levers based on some engine condition parameters
I see that you included titles in the letters from NPCs. Are you planning to include an option to change title (Mr. / Ms. / Mrs. / Mx.) and such in game?
It's honestly incredible how much you accomplish in such a short timeframe. You don't really see people interacting with communities of this scale while single-handedly writing a massive project, editing videos about said project, and doing the same thing concurrently with another even larger project. How do you find time in your day to sleep lol.
The thing about the throttle is that your AI system is basically exactly how real life steam engines controlled their throttles and were able to maintain extremely consistent RPMs. Real life steam engines in industrial settings used a centrifugal govenor, where the output wheel was linked to a vertical rotating shaft with two balls. As the wheel sped up the balls would swing further out and close the throttle and when the wheel slowed down it the balls would fall inwards and open up the throttle valve, you can find schematics for it in one of James Watt's historical patents. Basically a mechanical feedback system that was remarkably effective, in fact so effective that steam engines make for some of the most accurate mechanical clocks. Perhaps you should just add the centrifugal govenor as either a difficulty setting or an upgrade, you could include it along with other historical upgrades to the steam engine like a double acting piston, firetube boilers and compound expansion. Also a consequence of the centrifugal govenor is that historical steam engines were able to maintain a consistent RPM by varying their wattage.
Yeah. Responding to changing power demand or other conditions should be a challenge, but in reality keeping a power plant stable under constant conditions was a solved mechanical problem so the player shouldn't need to babysit it. Though, a breakdown of your governor forcing you to BRIEFLY manually control it could be an interesting disaster.
Honestly, I got into watching your vids by the Gen1 Engine Simulator videos I found while randomly hitting youtube. Now? Well, I'm here for the science lessons, and I'm waiting for the Steam Engine DLC. I know that it's going to be an excellent piece of work and I will definitely enjoy it. Keep up the good work and ignore the people who can't criticise constructively!
I want the steep learning curve and no spoon-feeding. KSP frustrated the shit out of me but it was soooo rewarding when I conquered things, because it was just me vs a game mechanic. I feel like story modes in general detract from that, so if it's appropriate to add a sandbox mode with zero help I would definitely try that option first.
I know this is a selfish request, but I'd like you to recompile it for linux, so that I and the other players that have linux-based systems can enjoy it without too much virtualization
16:30 I study computer svience and I got second hand anxiety from watching this video. I can't even imagine how stressful it is to undertake such a massive project ❤
As someone who has developed software for years myself, I find one of the harhest parts to be how the majority of people simply do not have the prerequisite knowledge necessary to understand how much time and effort it takes to actually develop high-quality software. This is, of course, not their fault -- I can't expect everyone to know the details of software development. But it is one of those pain points every dev has to deal with, particularly solo/indie devs. Kudos to you for working through that and making a product up to your standards, while also taking harsh criticisms to heart and making big changes!
10:10 is that control theory sneaking in? Imagine a DLC for the DLC where you need to discover the plant transfer function, and tune a PID controller for the engine, maybe extend it to a MIMO problem :)
Please find a balance to avoid burn-out. Negative feedback can be crushing. I wish you all the best with whatever you will decide. I admire the effort you put into this and your approach. You really are Great!
Does this confirm that you're doing engine sound design with beamng? All of your simulators are incredible for sound, this would be a really incredible collaboration to see
At the end of the day, ultimately what you are putting your effort into is honestly of little concern to me. The reason I continue to come back to your projects and channel has less to do with what specifically you're doing and more to do with how you're doing it. Your meticulous attention to detail and consistently impressive ability to design solutions to issues you encounter is really captivating, and it's clear that you have a great passion for the things you work on and want to do them right. This project didn't gain a large following because what you're designing was something people really wanted, but rather because people enjoy seeing skilled, passionate individuals perform their craft. Just keep doing things the way you enjoy doing them, and I've no doubt that the end products will turn out fine, and your audience will continue to enjoy watching you work your magic.
12:55 The reason taking an average doesnt work is because you need to root mean square. The average of a sine wave is its DC offset. RMS gives you the effective power delivered
You keep going. It’s insane to me the level of commitment and passion (though I suspect you might not like working on this as much as you did previously lol) you have for this. Nobody is perfect, but you’re doing pretty dang great
You didn't mention it, so I don't know if it's something you thought about but couldn't figure out the feasibility of, but when you don't want to do a tutorial yet want to fix the learning curve, one of the easiest and most intuitive methods is to adjust when players have access to features (similar to AI but less overwhelming). One example: to teach players to deal with expenses, a simple way would've been simply to disable most of the economy at first, only keeping expenses. Anyway, I know it's unlikely to be something you'd want to revisit, so good luck working on Engine Simulator!
12:54 is it that the demand -> price function is nonlinear? if it was a linear function, the (function of the average of demand should) be the (average of the function of demand) and linearity is a common assumption
You are a rare find as a game dev, thank you for taking the time to make things right and taking the time to listen to the community, that means a lot! Even if the community can sometimes be harsh and less than helpful! I appreciate all of your hard work!
Bro there is literally no greater hive of scum and villainy than the steam update comments, for no reason whatsoever they are absolutely brutal and unhinged and are never happy, please never look at them
I love that the term AI has finally reached the point where a control loop is finally an AI 😂 Edit: yes, I do know that NPC behaviour usually referred to as AI too
I acknowledge that you edited your comment but I just want reiterate, LLMs and the "AI" of today has very much hijacked the term "AI". So you have the progression a bit backwards. Until very recently, the term AI for games had a very specific meaning and most of these AIs were very simple state machines and nothing more. My usage of the term is not incorrect, it's the fact that the term has been monopolized by LLMs and modern machine learning that is the problem.
@@AngeTheGreat In addition, the term is hopelessly overused these days. To the extent that it is about to or has already lost any meaning. See all the random claims of “A.I.” PC parts manufacturers. It is ironic that legitimate uses like Ange’s are now called out in what must be a sort of attempt to over correct this trend. The hype really must be nearing its peak.
Given f(x) and introducing as the notation for "average", it quite immediate to show that if f(x) is a nonlinear function of x, in general f() is never equal to .
I haven't bought Engine Simulator yet, but I watch every video. The content is very interesting and one day I will definitely pick up the game. Thanks for the cool content.
Ain't no way, I just randomly though "Lets check if Ange has posted a new video, it's been a month now" and here I am, just 1 hour after you posted it.
Kinda funny, I just came from watching LGR's "SimHealth" game review, which is essentially the original SimCity + healthcare system economics. SimHealth allows you to do some incredibly fascinating stuff with it, but it just wasn't fun unless you were already trained on the subject. I think you're doing a lot better than SimHealth in the "fun" department, and showing it's still possible to make a complicated, model-driven sim fun. Btw as a frontend dev, I must compliment the consistent feel you've built with the interface.
You better not release an unfinished game. I demand you make your game the best game it can possibly be, even if that means neglecting your youtube channel.
I think my comment got autoremoved due to having a URL in it, so I'll try again. As a kid, I used to watch TV with closed captions, and it dramatically improved my reading comprehension. I'm also a big fan of Tom Scott's commitment to a11y. With those two points in mind, please (to steal a phrase from Tom) "buy some damn subtitles". RUclips's auto-captioning just isn't the same, it fails miserably with technical content like yours. I suggest Amara, which is what Kurzgesagt uses. Amara also supports languages other than English. Hell, I'm a Grease Monkey patron and I'd be willing to help transcribe your videos for free.
@@hobbified That's why I said I'd be willing to help for free, to offload some of the work. I could have a deep learning transcribing tool ingest videos, and then manually touch up the subtitles. Or even start with YT's autosubs.
I think its important to keep in mind feedback isn't creating problems, its identifying them., for example at 2:45, you mention getting the negative feedback wasn't a great experience. The negative feedback you get in playtesting phases, is doing nothing but IDENTIFYING problems and issues that already existed, you just missed them. it FEELS very overwhelming when you start the first round of playtesting, but these issues would either go unresolved and unnoticed if this wasnt done, and you would end up with a complete failure on launch. Playtesting/QC phases only seem to bring up new issues, in reality, they are issues that were there all along, but unidentified. I found keeping this in mind helped to take the sting from some of the playtesters comments
Hello, first timer here, this video has been recommended to me. It looks like a good project, and a great presentation too. Just one thing I've found is that it's really weird from what you've said: "One of the main objectives of the game is to increase the town's population", but I haven't seen a single number or graph that directly measures it, other than achievements. It's not that odd that the players keep maximizing profits when the big numbers on the center of the screen are about money, not the town's healthiness.
@9:33 I think it would be fun to have a "gremlin mode" where the AI maliciously messes with your setting lol. Also, please make a mode with no explanation, I'd like to try it. You also could do a tutorial type thing where the game starts with no explanation, the player accrues debt, and then a helpful person is like "hmm seems like you need a hand." Now the player has to work off that debt lol
100% gonna buy this next paycheck. a friend of mine plays and loves it, and this cements that not only is it a great game, but its headed by a fantastic dev. great work Edit: holy shit it's free, absolute GOAT dev
ange take your time! you deserve it i believe it's really hard to do this, you don't have to be so focused and be stressed on this! take breaks for weeks maybe even months, you already did a ton for us!

I also think that it would make it more difficult to spiral into a negative account balance like so many testers seemed to do, if you could store power in a battery you could use that strategy. Let some energy from the battery out during the day when demand is higher and let it charge at night when demand is lower. You could also hold a battery charge and use it as an emergency tool! If something unexpected happens you could salvage the situation or reduce the damage by using the battery power. But if you rely too much on the battery then you could find that a problem or fault in your power storage could be devastating! I already mentioned a storm could take down the battery but what if the battery could catch fire? Or if you overcharge it could get damaged and possibly explode?! This would not only cost money to fix but it would also mean you'll lose all or most of the charge you accumulated, power that could have been sold directly for profit. Basically. The battery could add a risk vs reward mechanism. Where if managed properly could be helpful but if managed poorly could be very detrimental- and it could all technically be optional. As in you are never required to use the battery but you can if you want to.
I hadn't heard of your game before now, but the video was quite interesting and now I'm interested in the game too. The youtube algo worked for once??
will it be done until december this year?
What if you could operate the engine "inefficiently" producing excess power, but then you had the option to build power lines connecting to neighbor cities and sell them the exceeding power, like in Cities Skylines? (But only to a certain stress threshold where the engine would wear to fast and require too much maintenance to be profitable)
How do I sign up to be a tester? I'd love to check this out
What about Simulation and Casual game modes?
82,000 lines is impressive for how small it is.
Using an AI to slowly transfer responsibility to the player is a great idea. Maybe the game should present the AI not as an AI, but as an elderly engineer who wants to retire, and is training the player to take over for them.
I probably should have made it more clear in the video but the AI engine controller is part of an actual NPC's AI, the mechanic I mentioned in the video. So your idea wasn't far off from what I was doing lol. Thanks for the suggestion!
i would recommend personifying the AI, maybe mockup a simple egg head blank face with a victorian style hat and give them a neutral name.
At this point I think I've helped inflict more psychic damage than my patreon will pay for, my bad
Looks like ur comment might have reversed it
Now go fix that my child soldier 🫡
The handover from AI to player can have its own storyline of some seniors at a workplace guiding your way while slowly stepping back
I had that exact same thought
YES!
Have an early "bad ending" where you deliberately sabotage the power plant once you get the responsibility
And then overtime they all die under suspicious circumstances and it leads into the next DLC, which is somehow a detective DLC..

4:00 I just want to tell you that I look forward to every video and they really do make me happy :)
Thanks, I'm glad to hear that
I agree. All of your projects are super interesting!
13:10 When accounting for power generation, the higher amounts of power demands need to be weighted heavier. Under-producing power isn't an option, so the price has to lean towards the maximum, not the mean.
NOOO
soop
Under-producing is an option, it is just that it will annoy people to various degrees depending on the severity.
There is a choice to commit rolling blackouts in the States
@@Aereto Rollingblackouts is a Capacity issue, and it is used to prevent a total black-start.
2:26 as someone who worked on nuclear power plants I kinda love this. It is incredibly hard work and we follow extremely strict SOPs set out by physicists for a reason. Heh while you didn’t set out to build a rage game. I think the difficulty is inherent to the subject matter and I like that your initial builds did not shy away from it.
Agreed. I want to play the first alpha
I'm not going to lie I really kinda want to try the realism mode one that made people mad. "I can fix her" but ... a steam engine?
That cable snapping event needs a lot of sparks lying all over the screen, with the cables continuing to spark as long as they are broken to really sell that something is not right.
it was fun being a tester even though my boiler kept popping
*crunchy sad cat face image
@@nairocamiloLOL
you took adverse feedback, made the changes, and didn't once sound angry. absolute legend!
11/10 game dev, can't wait for engine simulator to release!
I don't think you should worry about making a steam train simulator. To all the people who really want that, check out the in development game Century of Steam, which is a 3d narrow gauge railroading game that simulates realistic locomotive firing, operation, and railroad management.
Give Ange some breathing room, let him finish this up and get to engine simulator.
We watch you for you. Whatever you make I'll watch.
Ange remember, we all love you (at least the patrons do)
Not just patreons
Wasn't all this frustration PRECISELY because of the Patreons?
@@lucchesi87 well the Patreons just gave him honest feedback on the game which he asked for. Ange wasn't frustrated, he was just not sure what to do since he has a heavy workload right now and has to choose what to prioritize.
but that has NOTHING to do with the Patreons, they just did what he asked them to.
If they hated your game, they would be outraged at the turbofan test cell simulator I built years ago while working for Lockheed and Rolls-Royce at Stennis Space Center.
I'm a former turbofan test engineer. Back in 2010 I designed and built a 6 screen stimulation, including a custom throttle, that simulated the testing of large jet engines. Specifically the Trent 9000, 1000, and XWB. The simulator had failures to test the crews reaction to problems as well as a playback of a real jet on our test stand that was synced to the simulated jet engine run condition.
It was used to allow training of test crews without risk of damaging a real jet.
That sounds like a fun thing to watch, at least.
@@scottwatrous, it was interesting! I had a blast building and programming it for over six months. The test crews and other facilities also enjoyed using it. Better than destroying a 20+ million dollar R&D engine!
@@JarheadCrayonEater But the high stakes are always so much fun! (and stressful)
Yeah, when you're training to test 20 million dollar jet engines, and it's literally your job, the threshold for acceptable complexity and finesse is admittedly a whole lot higher than somebody who wants to have fun playing a little steam engine game for 20 minutes.
I’m excited for the dlc
"instead of maximizing population maximized profit" capitalism by definition lmao
At 13:00: The average-value operator does not (in general) commute with a nonlinear function. This could be "fixed" by having price-by-demand simply be a linear function, but that would probably be boring. Instead, an effective but approximate solution would be to sample demand at several points during the day, take the price at those points, and average those samples. As long as demand isn't too spiky and the price-by-demand curve is smooth, that should be close enough to the true value.
That's basically it. The precise solution would be using calculus, though. You'll have to redefine average as taking an intergral and then dividing it by the period over which it was taken. Then you'll just take the average of the price as a function of demand, with demand being a predefined curve in this case.
You need to integrate two different things. First, you integrate demand * fair price vs demand to get a total price for the amount of power needed that day, then you divide by the total demand for the day (integration of demand).
l love how this "quick tech demo'esk side project" became a full game release with story, quests, etc
yer AI gizmos might be handy later if you ever implement automatic transmissions or EFI in engine simulator, those are both effectively black boxes trying to optimize something by flipping levers based on some engine condition parameters
Thanks for the update!
Thanks for watching!
I see that you included titles in the letters from NPCs. Are you planning to include an option to change title (Mr. / Ms. / Mrs. / Mx.) and such in game?
It's honestly incredible how much you accomplish in such a short timeframe. You don't really see people interacting with communities of this scale while single-handedly writing a massive project, editing videos about said project, and doing the same thing concurrently with another even larger project. How do you find time in your day to sleep lol.
The thing about the throttle is that your AI system is basically exactly how real life steam engines controlled their throttles and were able to maintain extremely consistent RPMs. Real life steam engines in industrial settings used a centrifugal govenor, where the output wheel was linked to a vertical rotating shaft with two balls. As the wheel sped up the balls would swing further out and close the throttle and when the wheel slowed down it the balls would fall inwards and open up the throttle valve, you can find schematics for it in one of James Watt's historical patents. Basically a mechanical feedback system that was remarkably effective, in fact so effective that steam engines make for some of the most accurate mechanical clocks. Perhaps you should just add the centrifugal govenor as either a difficulty setting or an upgrade, you could include it along with other historical upgrades to the steam engine like a double acting piston, firetube boilers and compound expansion.
Also a consequence of the centrifugal govenor is that historical steam engines were able to maintain a consistent RPM by varying their wattage.
Yeah. Responding to changing power demand or other conditions should be a challenge, but in reality keeping a power plant stable under constant conditions was a solved mechanical problem so the player shouldn't need to babysit it. Though, a breakdown of your governor forcing you to BRIEFLY manually control it could be an interesting disaster.
Just wondering if you can change the title of the engineer from Mr to anything else
Honestly, I got into watching your vids by the Gen1 Engine Simulator videos I found while randomly hitting youtube. Now? Well, I'm here for the science lessons, and I'm waiting for the Steam Engine DLC. I know that it's going to be an excellent piece of work and I will definitely enjoy it. Keep up the good work and ignore the people who can't criticise constructively!
I want the steep learning curve and no spoon-feeding. KSP frustrated the shit out of me but it was soooo rewarding when I conquered things, because it was just me vs a game mechanic. I feel like story modes in general detract from that, so if it's appropriate to add a sandbox mode with zero help I would definitely try that option first.
I know this is a selfish request, but I'd like you to recompile it for linux, so that I and the other players that have linux-based systems can enjoy it without too much virtualization
16:30 I study computer svience and I got second hand anxiety from watching this video. I can't even imagine how stressful it is to undertake such a massive project ❤
As someone who has developed software for years myself, I find one of the harhest parts to be how the majority of people simply do not have the prerequisite knowledge necessary to understand how much time and effort it takes to actually develop high-quality software. This is, of course, not their fault -- I can't expect everyone to know the details of software development. But it is one of those pain points every dev has to deal with, particularly solo/indie devs. Kudos to you for working through that and making a product up to your standards, while also taking harsh criticisms to heart and making big changes!
I just turned 14 and I’m always looking up to you and it’s my dream to make stuff like you
Glad I got to test this, it was fun being a pain in your neck! (sorry)
10:10 is that control theory sneaking in? Imagine a DLC for the DLC where you need to discover the plant transfer function, and tune a PID controller for the engine, maybe extend it to a MIMO problem :)
I want this so much
Cant wait for the DLC, ive been waiting for ages for it
Please find a balance to avoid burn-out. Negative feedback can be crushing. I wish you all the best with whatever you will decide. I admire the effort you put into this and your approach. You really are Great!
Does this confirm that you're doing engine sound design with beamng? All of your simulators are incredible for sound, this would be a really incredible collaboration to see
At the end of the day, ultimately what you are putting your effort into is honestly of little concern to me. The reason I continue to come back to your projects and channel has less to do with what specifically you're doing and more to do with how you're doing it. Your meticulous attention to detail and consistently impressive ability to design solutions to issues you encounter is really captivating, and it's clear that you have a great passion for the things you work on and want to do them right. This project didn't gain a large following because what you're designing was something people really wanted, but rather because people enjoy seeing skilled, passionate individuals perform their craft. Just keep doing things the way you enjoy doing them, and I've no doubt that the end products will turn out fine, and your audience will continue to enjoy watching you work your magic.
This game is very intriguing, if only it worked for Mac computers. :)
I always think of the quote "A delayed game is eventually good, but a rushed game is forever bad" - Shigeru Miyamoto
12:55 The reason taking an average doesnt work is because you need to root mean square. The average of a sine wave is its DC offset. RMS gives you the effective power delivered
Hey, I spent 4 years subbed to Randy (the arcana guy) so there is no way to out-dissapoint me at this point.
"When given the opportunity, players will optimize the fun out of a game."
Maximising profits instead of people, I wonder where I have seen that before
You missed your opportunity using the word "pressure" in your thumbnail, rather than "stress"
Not much relation to this video but i can see your engine sim bein used on electric cars like the new electric Dodge for example
You can save space by changing the °C/°F to just what the user wants to see of either of those
6:59 they are playing the game correctly under the free market, if the free market wanted cheaper energy it would have lowered the prices smh
It did, that's why everyone left the city 😂
You keep going. It’s insane to me the level of commitment and passion (though I suspect you might not like working on this as much as you did previously lol) you have for this. Nobody is perfect, but you’re doing pretty dang great
Damn bro, why was Ange so aggressive in the intro of this video?
You know I wish I can hear those words coming from many other devs, but you my friend, you did it, thank you. :)
Always love hearing that BeamNG is a supporter
You didn't mention it, so I don't know if it's something you thought about but couldn't figure out the feasibility of, but when you don't want to do a tutorial yet want to fix the learning curve, one of the easiest and most intuitive methods is to adjust when players have access to features (similar to AI but less overwhelming).
One example: to teach players to deal with expenses, a simple way would've been simply to disable most of the economy at first, only keeping expenses.
Anyway, I know it's unlikely to be something you'd want to revisit, so good luck working on Engine Simulator!
12:54
is it that the demand -> price function is nonlinear?
if it was a linear function, the (function of the average of demand should) be the (average of the function of demand)
and linearity is a common assumption
yes, he needs to average after the result of demand * price, not average demand then * price
Can you add a hotkey to the debug menu in the final release.
who loves the kawasaki z series z750 z800 z900 z1000
I look forward to this dlc. i know making stuff like this isnt always easy, but ur doing a great job, keep up the good work!
I hope that we can play the DLC soon
You are a rare find as a game dev, thank you for taking the time to make things right and taking the time to listen to the community, that means a lot! Even if the community can sometimes be harsh and less than helpful! I appreciate all of your hard work!
Bro there is literally no greater hive of scum and villainy than the steam update comments, for no reason whatsoever they are absolutely brutal and unhinged and are never happy, please never look at them
I'm assuming the market average price issue was a matter of volume weighted average price (VWAP) vs time weighted average price (TWAP)
I love that the term AI has finally reached the point where a control loop is finally an AI 😂
Edit: yes, I do know that NPC behaviour usually referred to as AI too
Yeah if that's AI your lightbulbs and phone chargers are AI powered too...
I acknowledge that you edited your comment but I just want reiterate, LLMs and the "AI" of today has very much hijacked the term "AI". So you have the progression a bit backwards. Until very recently, the term AI for games had a very specific meaning and most of these AIs were very simple state machines and nothing more. My usage of the term is not incorrect, it's the fact that the term has been monopolized by LLMs and modern machine learning that is the problem.
@@AngeTheGreat In addition, the term is hopelessly overused these days. To the extent that it is about to or has already lost any meaning. See all the random claims of “A.I.” PC parts manufacturers. It is ironic that legitimate uses like Ange’s are now called out in what must be a sort of attempt to over correct this trend. The hype really must be nearing its peak.
Ive been wondering for a while now, WHO IS JOE??
It's Joe
amazing question, who ever could Joe be
I’d love to see a completely autonomous mode! Perhaps you could fiddle with the load yourself and see how the program deals with situations.
Don't give up!
Given f(x) and introducing as the notation for "average", it quite immediate to show that if f(x) is a nonlinear function of x, in general f() is never equal to .
W video how tf have so many other people commented it was released 3 min ago 😭
Released on Patreon first maybe
@@SamyasaSwi Yeah I guess
I haven't bought Engine Simulator yet, but I watch every video. The content is very interesting and one day I will definitely pick up the game. Thanks for the cool content.
Heed the warning, adventurer. Caving to people with skill issue is how you go from making simcity to making farmville.
I am here for everything because it's fun. I understand that you're 1 guy trying to do multiple things. so take your time.
Ain't no way, I just randomly though "Lets check if Ange has posted a new video, it's been a month now" and here I am, just 1 hour after you posted it.
Same lol
you need to get subbed asap
@@tostitossssss done lol
Kinda funny, I just came from watching LGR's "SimHealth" game review, which is essentially the original SimCity + healthcare system economics. SimHealth allows you to do some incredibly fascinating stuff with it, but it just wasn't fun unless you were already trained on the subject. I think you're doing a lot better than SimHealth in the "fun" department, and showing it's still possible to make a complicated, model-driven sim fun.
Btw as a frontend dev, I must compliment the consistent feel you've built with the interface.
Hi Ange
You better not release an unfinished game. I demand you make your game the best game it can possibly be, even if that means neglecting your youtube channel.
I think my comment got autoremoved due to having a URL in it, so I'll try again.
As a kid, I used to watch TV with closed captions, and it dramatically improved my reading comprehension. I'm also a big fan of Tom Scott's commitment to a11y.
With those two points in mind, please (to steal a phrase from Tom) "buy some damn subtitles". RUclips's auto-captioning just isn't the same, it fails miserably with technical content like yours.
I suggest Amara, which is what Kurzgesagt uses. Amara also supports languages other than English. Hell, I'm a Grease Monkey patron and I'd be willing to help transcribe your videos for free.
I'll see what I can do, thanks for the suggestion
yay more demands
@@hobbified That's why I said I'd be willing to help for free, to offload some of the work. I could have a deep learning transcribing tool ingest videos, and then manually touch up the subtitles. Or even start with YT's autosubs.
And then people keep complaining that game developers don't show what they're working on...
I think its important to keep in mind feedback isn't creating problems, its identifying them., for example at 2:45, you mention getting the negative feedback wasn't a great experience.
The negative feedback you get in playtesting phases, is doing nothing but IDENTIFYING problems and issues that already existed, you just missed them. it FEELS very overwhelming when you start the first round of playtesting, but these issues would either go unresolved and unnoticed if this wasnt done, and you would end up with a complete failure on launch.
Playtesting/QC phases only seem to bring up new issues, in reality, they are issues that were there all along, but unidentified. I found keeping this in mind helped to take the sting from some of the playtesters comments
The Editing and Logical progression is outstanding. having never played the game, the video makes me want to try it out
Hello, first timer here, this video has been recommended to me. It looks like a good project, and a great presentation too.
Just one thing I've found is that it's really weird from what you've said: "One of the main objectives of the game is to increase the town's population", but I haven't seen a single number or graph that directly measures it, other than achievements.
It's not that odd that the players keep maximizing profits when the big numbers on the center of the screen are about money, not the town's healthiness.
it's crazy how much people expect from 1 guy. don't be afraid to take a break.
Ahhh if RL would be so accommodating...
Complain on how crappy and difficult the gameplay is and magically somebody nerfs your utility bill...
@9:33 I think it would be fun to have a "gremlin mode" where the AI maliciously messes with your setting lol.
Also, please make a mode with no explanation, I'd like to try it.
You also could do a tutorial type thing where the game starts with no explanation, the player accrues debt, and then a helpful person is like "hmm seems like you need a hand."
Now the player has to work off that debt lol
100% gonna buy this next paycheck. a friend of mine plays and loves it, and this cements that not only is it a great game, but its headed by a fantastic dev. great work
Edit: holy shit it's free, absolute GOAT dev
ange take your time! you deserve it i believe it's really hard to do this, you don't have to be so focused and be stressed on this! take breaks for weeks maybe even months, you already did a ton for us!
I'm sorry, but if a throttle is stuck open, I am disconnecting the generator, emptying the boiler and removing the fuel source.
