Quote from danthebangerboy :
Am i right, do i have a point, or am i just being OTT about it??

That's almost exactly what my upload and download speeds are from home. It was my choice because I chose the cheapest DSL service that AT&T has to offer in the USA.

I've heard that Europeans generally get much faster speeds in their homes than we do here in the USA. So for that, maybe you do have a point and I am jealous of those who do get the faster speeds, especially if the cost is reasonable.

Quote from RX-7 :What should it be then ?
If i use my router ip it comes up with the TCP socket bind failed error.

It should be the address assigned to your computer.

It would be something like 192.168.1.64 or 10.0.0.64 or something similar.

You can't use 127.0.0.1 because that's an address that is only used internally.

From a Windows command prompt, use the "ipconfig" command. Then look at the line that says "IP Address". It will tell you what you need to know.

I haven't experimented with it yet to see if it's true, but I seemed to notice that when I set my own skill level to something lower than PRO, the AI didn't seem to be so aggressive. One time I tried it, the AI actually tried to avoid hitting me.

On a lower skill level, they don't drive as fast, so maybe they pay more attention.

Quote from RasmusL :Did you remember to turn aids off? In the settings you have brake help and stuff.. The rear brakes seemed pretty good to me, I didn't even notice there was a front brake

Yup, when you're riding around, look down by the wheels, you can see the calipers.

This could be a good subject if you separate it a little further. How about the hardest single seater/track combo and the hardest enclosed/tin top car/track combo?

Also, since the single seaters don't really belong on the rallycross courses, those combos shouldn't be considered.

The UF1 at KY1. Maybe that shouldn't be considered either.

Now for my selections? I haven't driven each car enough to give an honest answer. However, I've driven a few cars a lot. I'll come up with something when I get more time with each car on each track.

But I'm guessing for the single seaters, it's going to be the BF1 due to the shear acceleration it has and the speed that it can reach before entering a corner and not being able to actually feel it in the seat of your pants.

For the multi-seat cars, it's probably going to be the RAC due to it's washy feeling. I'm sure it can be set up better, but I haven't spent any time with it yet.

As for the tracks, any track where you can't see the turn coming up until you are right on top of it can be tough until you learn the track real well. I've found that to be a problem with netKar Pro, most of the turns you can't see until you get right there and then I'm off into the grass with an unrealistic sound of the car riding on the ground. Most of the LFS tracks seem to have good visibility of the actual track surface and there is enough scenery to gauge from, except for maybe some turns at KY2 and KY3.

Did you try the command "/axlist" to see if the layout is listed? If so, then use the /axload command to load it.
It might not show on the track selection screen. You might have to manually load it using the axlist and axload commands.

/axload layoutname

Where layoutname is the name that is shown when you use /axlist.

Quote from Mysho :Compare his join date with yours.

After 5 years of you being involved in LFS, we can talk about this. I'm sure you won't be as optimistic as now.

Yet, I have also paid for rFactor and nkPro and they are both good, but I haven't seen how they are better than LFS. So, the length of time I've spent with LFS isn't a factor, because it's the same length of time I've spent with the other simulators and I see LFS as being the better one. I'm not knocking the others, I just think overall, LFS is better.

And being a programmer myself, I can appreiciate what Scawen is going through (including Eric and Victor). They aren't typical programmers, as they prefer to get as close to perfection as possible before release. I can see that in their work. Look at the overall picture, the detail on the tracks and cars and how everything works. It's very good and very well thought out.

And since this is a CPW thread and we've gone a little off topic, I'm glad that Scawen is trying to curtail the cheaters. Cheating isn't winning.

Quote from AProst :+1

I am racing with nKPro waiting for LFS to improve... maybe one day. :/

I don't understand why you think it needs to improve. It's a very good simulator. It hasn't gotten bad, how could it? If it was very, very good a year or two ago and nothing has changed, then it is still very, very good. In fact, an improvement was made just about a year ago and another improvement just recently by stopping some cheating.

Does it take something new to spark your renewed interest? Certainly you haven't mastered every single car combination on every available track configuration yet. I'm sure there is still something for you to explore. And besides, if you participate online with LFS, that's where the excitement is, no matter if LFS has a new revision or not.

I've found that if I just go into a server and ride around for a short time, someone else will come in. Then another, and another, and now we have a race! And it's fun. That's what it's all about.

I have noticed quite a few people getting bumped during the connection process with the CPW notice.

I also haven't noticed any extra fast drivers on my servers since this was introduced, unless there have been some when I wasn't around.

Overall, it's been much better for everyone, especially for those who can't figure out why they aren't as fast as some.

Thanks for doing this.

If I was living in the UK, I'd love to come, but I'm in the USA.

Maybe I could be there virtually, though. If you want to invite people from all around the world to at least be a part of the chatting, racing, drifting, crashing, etc part of it, I'd be willing to set up however many servers would be needed just for this event. 5, 10, 15 servers? I also have a regular chat server running the Ignite software if you wish to use that for this event.

Just an idea, charge everyone $1 through PayPal to get a password and use the money to help finance your party.

Scawen and the rest should come too. Even if the next patch or S3 isn't close to being ready, they could still use this event to show off what they have such as Rockingham and whatever else they might be willing to reveal.

Quote from JohnPenn :I wish someone would run a server with a different track each day for the XFG /XRG much like it was with CTRA.... I really liked that.

Our servers change around every day or so. One of them currently is for S2 users and only allows the XFG and XRG. It defaults to Blackwood GP, but is set so the users can pick any track they like.

We currently have 6 servers running 24 hours a day. Our servers are easy to find, they're names all begin with "[ROTW-USA]". The servers are located in the USA, but many users from all around the world have been able to make decent connections. They work good because we set them to send 6 packets per second. If a couple of packets get lost, 3 or 4 will still make it every second. Plus we don't see the need to allow 47 connections. 10 or 12 users running smoothly makes for a very enjoyable experience.

We don't allow crashers. If we happen to be monitoring and see a crasher, he will get booted. Also, for newcomers or those who are still struggling to find speed, one of our servers is just for those people. It's OK if you are slow on the following server:

[ROTW-USA] 1:37 and slower only

That one is a demo server at Blackwood GP. You fast guys, please ignore that server. Let someone have a chance at winning!

Quote from PhilS13 :Oh ok well sorry I just thought I previously read here that the roll center of a bike or a car on two wheels was right under the contact patch. I must have deeply misread.
End of the offtopic.

Perhaps a more appropriate term would be "pivot point" rather than roll center.

Quote from PhilS13 :

Whatever point you are describing is not a roll center. Well it is...right until the moment the car starts to...roll. Kinda ironic.

Which is why I said the roll center is almost meaningless. There is much more to making a car handle than worring about its roll center. Which is why I also pointed out that a bicycle really does not have a roll center, yet you can make a bicycle handle quite well. Weight placement is the key.

Lots of ways to describe this and look at it.

There was a time when I too thought that moving the center of gravity below the "theoretical" roll center and causing the chassis to lean in the direction of the turn would make it handle better because it would add more weight to the inside tires. That was a time when I didn't think correctly, or enough. In a case like that, would the chassis be applying more weight to the inside tires? After all, the springs are being compressed and the spring pressure would put more load on the tires. HOWEVER, I have never seen a car appear like this when cornering! So, is it really possible? And if it does happen, maybe the chassis isn't really compressing the springs. Maybe the tires are trying to lift against the chassis and that's why the springs are compressing?

Picture in your mind, the center of gravity being below a roll center, but still above the point where the outside tires contact the road. That center of gravity is headed in a horizontal direction above the contact point of the outside tires. That force will tend to lift the inside of the chassis no matter where the roll center is located. The combination of the chassis trying to lean to the inside and the force trying to pull the whole chassis to the outside and pivot on the outside tires, maybe the car will just lift a little and remain level. That would become a jacking effect on the right side suspension. Not too desirable.

The topic can get pretty involved.

Quote from RasmusL :It works in some instances, but if we imagine the vehicle tipping on it's side and driving on 2 wheels, it will of course be rolling on the bottom of the tyres like a bike, and not at the geometrical point. I guess that's my little contribution here

That is correct. A bicycle's roll center can only be at the contact point between the tires and the road.

Even if the bicycle or motorcycle has front and rear suspensions, they simply allow the frame to move up and down in relation to the tires, the frame does not roll unless the tires also roll. So, the roll center is at the contact patch.

Calculating the roll center of a 4-wheel vehicle is really only meaningful when the vehicle is at a standstill or moving in a straight line or just at the very instant of beginning to turn into a corner. Beyond that, everything changes unless the car is not allowed to roll, in which case, the roll center is still meaningless. Once the car rolls in a turn, everything changes because the control arms which are used to calculate the roll center are all changing angles. Their mounting points are also moving in relation to the distance from the ground. A completely different calculation is needed when the car is leaning.

And the more the car leans or rolls, the less meaningful the roll center becomes, because just at the point where the inside tires are about to leave the ground (assuming enough grip on the outside tires) the roll center is about to become null or based at the contact point of the outside tires to the road.

The bigger the swaybar is, the sooner the inside tire will be to lifting off the ground. A bigger swaybar causes the inside tire to be less useful and the outside tire to be more useful, at least until the outside tire can no longer handle the load.

I'm always thinking about things like this.

A 4 wheeled vehicle is not much more than 2 bicycles connected together with some tubing and linkages.

To keep things simple, let's always assume left hand turns.

Ride your bicycle and go through a left hand turn. The only way you can keep from tipping over is to shift your weight to the left. If your weight goes to the right, you won't turn, you will be laying on the ground.

The right side tires of a car has the bulk of it's weight to the left. In a left hand turn, that weight is keeping the right side of the car from tipping over. On the other hand, the left side tires have all the weight to the right. In a left hand turn, the left side of the car is very bad and is trying to tip over, but the fact that it is connected to the right side of the car is physically preventing it from tipping over.

It doesn't matter where the roll center is or where the center of gravity is. Weight will always be shifted to the right in a left hand turn. The center of gravity is only important in relation to where the tires are contacting the road surface. The relationship of the center of gravity to the roll center only affects how the car ends up appearing in relation to the road surface, or how much or how little it leans when cornering.

Think about a go-kart with no suspension. Where is the roll center? What does the driver try to do in a left hand turn? He tries to lean to the left of the left side tires if the rules allow it.

On a bicycle, there is no roll center. Or is there? The roll center is actually at the ground where the tires make contact. The whole bike rolls to the left in a left hand turn. If it doesn't, the rider will be all scraped up.

There is a lot involved here. The above is just something to think about.

Quote from magicaldog :I'm convinced now after trying out the REALLY fast cars and it feels about the same as taking my own car for a spin on the highway at + 210 km/h.

In other words LFS feels the way a really good sim should.

Driving at 190+ mph down the back straightaway at Talladega doesn't feel as fast as it really is either. It's all wide open and so the true feeling of speed isn't there. Plus it tends to get quieter at that speed as all the sounds of the tires on the track surface and the engine sounds are starting to move rearward. Even the air rushing past (or is it the car rushing through the air?) is quieter, especially when the car is designed to help keep the air out of the interior.

LFS is the most realistic simulator out there. Scawen is doing the right thing by not rushing his updates. Programmers who get in a hurry to release their products never seem to get things right. LFS is very good.

Quote from Bob Smith :People editing the map is already starting to piss me off. I've had to put the description text back 4 times already, and somebody deleted my marker. :|

It's too easy to mistakenly edit the description because you have to click on "Edit" in order to place a marker. And it looks like it wants you to add text in the edit box for your marker. But obviously this box should be left alone and only the edit box that pops up when you actually place a marker should be edited by each user.

Google didn't lay this out properly. It works, but it's too easy to goof up.

Anyway, I'm added and am the first one to appear in Michigan.

Quote from TehPaws3D :Are you talking like ken block's place

Yes, something similar. Only more deserted. That place looks like it was still in use, somewhat. But I also vision a much larger open area where large layouts could be assembled.

Maybe being able to have junk trucks and cars along with some leftover factory objects to place around the layout would be good.

It's quite obvious there is a big desire for something like this.

Personally, I'd also like to see more race tracks as well. What we already have is very good, though. There is plenty of enjoyment to have now, because it takes a great deal of practice time to master each track. And with the number of cars available, that just multiplies the time you could occupy.

In addition to being able to place objects around the layout, picture this large deserted manufacturing facility I have in mind. Part of it is dirt and gravel, but the majority of it is asphalt and concrete. In the dirt area, it would be great to be able to build your own dirt piles. This would provide an endless number of self built rallycross layouts.

Something that would be very realistic would be a huge manufacturing facility that was closed down. It could cover a mile square and contain maybe 3 or 4 remaining buildings with 3 or 4 other buildings that have been torn down. A great deal of the facility could be asphalt that was previously used for employee parking as well as on-site storage. Grassy areas of the property as well as the area where buildings were torn down could be for non-asphalt racing. If one of the buildings was large enough, allow being able to drive inside it and set up an indoor course.

I think that would seem more realistic because you'll find closed up large factories more than you will closed up large airports.

Also:

1. Much longer barrier objects
2. Curved barriers
3. Eliminate the flying high into the air, especially when only hitting a barrier at 30 mph. This is about the only aspect of LFS that doesn't seem realistic.

I used some AI drivers to race against last night. I noticed that when I set my own skill level to a lower level, the AI drivers didn't seem to be as aggressive. I could race in front of them without getting spun out at every corner. So, maybe that's a good way to practice with the AI drivers.

This AI driver didn't seem to like it when I got into his left rear.

That whole track should fit entirely to scale on the autocross area. On the google map view that was posted, it appears to be roughly 150 meters by 400 meters. The autocross area is bigger than that. The short L leg would be extra empty space that could be used for something else.

In this one, one sign in this Kyoto set is replaced with a Budweiser sign. I have no idea what the sign is that is getting replaced. I can't read Japanese. I assume it's Japanese.

That one straightaway needs some signs instead of just the framework for them. There's a lot of signs that didn't get sold at Kyoto!

I wonder if the coding is already in place for signs there and if some are made and named correctly, that they would automatically show up? Anyone know?
