I'd really like to know the education and current job of the following gentlemen:

[1] Aleksandr_124rus
[2] Avraham Vandezwin
[3] SamH

You guys have very serious philosophical skills and a lot of free time. Tnx.

Awesome, keep going, we need more škoda cars, like new Octavia for example

Wow, very nice car model and the interior work is absolutely the best I've seen so far in any mod.

is it possible to edit the default shader somehow? like with notepad or something?

As far as I know, one can't go faster by flipping the car over If the AI tries not to flip the car, they will finish the lap, but possibly not faster. I do think that it is a good idea for AI to be "aware" of the car being on all 4 tires all the time.

Thank you everyone for this very nice feedback and for Scawen who implements all these tiny but important improvements. Together, we'll make LFS awesome.

This topic has turned into psychotherapy sessions, guys I'm just glad that I recognized it early and backed out before I started to get angry. I'll leave it to you to keep discussing, there were some indeed good points from everyone.

Scawen, the big problem with "all countries working together", is deciding on who needs to cut on what. Poor countries can't cut CO2 emissions as this is mostly by farming and transport of goods which will have a direct impact on their developement. On the other hand, rich countries don't want to give up their comodities. And the cruel fact is that poor countries where it is already quite hot and dry will be affected first by the effects of increasing Earths avg temperatures. At the moment, governments are in the stage where they try to pass the blame to everyone else saying you polute the most, you start cutting first. Others say, no you first, you rich bastard And so on, we enter an infinite loop where very little is actually done.

My guess is that, it's gonna continue like this as long as there is no single gram of fossil fuels left in Earth's crust. It's my fear that's gonna be a point of no return, but I hope people will become globaly aware of the problem and that slowly we humanity as a whole will redefine our attitude towards Earth, which in turn will affect governments.

Yes, that's my profile. I'm not in that field, you're correct. However, you can have a look, we have a joint papers with company Eaton, they produce big switchgears in energy production industry. Our project was on finding and inspecting suitable insulation gas replacement. At the moment SF6 (sulfurhexafluoride) is used world wide since 1940 and it's a strong greenhouse gas with a GWP (global warming potential) of 23.5k, where CO2 has 1. There was a legislative that put a ban on usage of SF6 by the end of 2025. Even though this is a bit of politics and there's no real danger of it due to much much smaller released quantities in comparison to how much CO2 is being released.

I say we're fked because an alarmingly big number of politicians who can make a change are not recognizing this as a warning sign.

Consequences, well, the scenarios are pretty much like apocalipse movies. I'll try to dig out a youtube video on this topic.

As a scientist, I say to you - global warming is real and it's man made, due to releasing of way too many quantites of green house gases in the atmosphere that stay traped there. Some estimates show that even if we completely stop emissions of all green house gases right now, the Earth would still need 50-100 years to recover on its own. So we are very much fked.

At the moment AI's are only better than humans in single tasks, like playing a particulair game or what ever. So far, there isn't an AI with general inteligence that would be able to do any given task. As long as we don't have that kind of AI yet, we're safe

But yeah, movie terminator judgement day already said it all. When I saw the movie I never thought such advanced computer is possible, but now I'm not so sure that we may not someday see some version of skynet.

This code is extremely confusing.

First make sure that you know the range for each of variables heading and direction. Then you can start doing the math with them. Why are you doing -360? It makes no sense, rotating by full circle in any direction gets you to the same point.

If you are intereated in value of heading-direction, then put that into the if statement and ask if it is less then zero. For me it is intuitive to have the zero where car direction matches its heading, and if you drift left to show negative and drift to right to show positive angle.

Let's wait for a new update and then continue this discussion. I now understand what you are saying and you are right. This is due to the 10ms time step of the current game engine, which simply isn't fast enough once one goest into the mentaly fast driving mode like you.

To me, AI is good as is, they follow a path very well. What needs work is calculating the optimal AI path. This is autogenerated if there isn't one already available. This algorithm is quite complex and tricky, but Scawen managed to do it somehow and we can even see some iteration steps and optimization during path autogeneration. If I were in his place, I would put my focus on improving this algorithm to generate faster lines, that use more track width have later braking points, and better effort to hit the corner apex as now all of them are too wide and too fast at corner entry.

I don't know which method Scawen used there, but the best approach for this is an implementation of deep neural networks with a genetic algorithm. This is the only way that AI can actually be somewhat aware and have a learning capability, but these things are state-of-the-art research at the moment and this would be an overkill to implement in LFS.

Yeah, having more than 100fps is not required because at the moment physics engine runs at 100Hz. If one has more fps than 100, every additional frame in between 10ms is just a duplicate of the previous one. Also, to be able to see all those frames, one also needs a display capable of showing at least 100Hz. The gameplay will never be smooth at 100fps displayed on 60Hz monitor.

A new update with 1000Hz physics engine will certainly help to fix this kind of synchronization issue between fps and display refresh rates because there will be a separate thread that runs the game engine and another one dedicated only to displaying graphics. Moreover, once you have 1000Hz game engine, it's much easier to synchronize the gfx being sent to display as the time step is 1ms. At 60Hz display can show a frame every 16.6ms. Now with a 1ms time step game engine can do this with much better precision than for example with a current engine that has 10ms time steps.

The final result, that we as end users will observe is simply a better game fluidity and more responsive simulation.

Yes, I see now. This is just sad

For the love of god, please get a Windows PC and play LFS as it's meant to be played. This Linux crap doesn't even deserve to be called LFS as the gaming experience is so bad that it's shameful, from gfx to fluency as you describe it.

It would help us if you attach a video of such inconsistency, because it is very hard for us to understand what you are talking about. To me, it seems very subjective how you percive things in LFS, I know that you are an extremely fast driver and that driving on the limit requres a special attention to smallest details.

A concept where you mentioned that time doesn't flow the same in every corner is quite fascinating for me as a scientist. It is well known since 1905 that time does not flow the same for all observers that move away with different speeds relative to each other. What you are proposing is a mind blow that similair phenomenon may exist even in the virtual world

Are you playing LFS in Linux? That may be the problem you are observing and not the LFS itself.

It seems quite normal if you have an internal dumper effect enabled, or if the damper ffb effect is playing.

It still doesn't make any sense to me. Unfortunately, I give up, maybe someone else can help..

You are looking at a wrong variable, angular velocity is a quantity that describes a rotational movement of an object per units of time. What you need is heading or angle of the car with respect to track coordinate system. One more thing, these angles are usualy given in the units of radians, so you will have to do some math to convert it back to degrees.

I have no idea what you just wrote, I don't understand what, do you mean by fluency? Are you talking about micro stutering? If so, just wait a little bit longer, the new update will have 1000Hz physiscs which should provide a very smooth gameplay and a minimal stutering (non-fluency) at any screen refresh rate above say 60Hz.

Servers with airio have a private chat feature. You can use command !pm +username to add people in private chat list !pm -username to remove them, then !pm text, where text is your message which will be sent to everyone in the pm list. All of the players have to do this in order to continue with ptivate chat.

Looks good to me as it is. Nice work man.

Wow Scawen, you're on fire, tnx very much for all of these nice AI updates

Not that I can't log in.

But another similar and extremely annoying thing happens quite often to me: I write a long reply that took me quite some time to write nicely, then click the reply button and the forum says: "Access denied, you don't have permission to post" and I'm logged out of the forum. After that, I lose motivation to write it again and simply do not reply..
