Yeah, I see an awful lot of open source projects that offer either an archive or self extracting exe for download.

The other thing that a lot of people either dont know, or are irritated by, is actually creating a shortcut once you've unzipped it somewhere. Granted, you only need to do it once, but nothing shouts shoddy to me like a demo download that you have to make your own shortcuts to.

Quote from Pain-less :Couldn't you just open Windows Explorer go to Tools>Folder Options>Flie Types and create a new file extension associated with LFS? It wouldn't play the file but it should just open LFS for you. Just a thought.

Yeah, thats the idea, but LFS needs to be written to handle being started with the file to open as a parameter. I presume there is a standard windows method that is called when you double click a file with a program association, which causes the program to launch and attempt to open that file. All that needs to be done is for LFS to 'open' replays.

Of course people would then need to manually associate mpr's and spr's with LFS.

Although obviously that might require a registry key, which would completely clog up your system and be bad and evil... or something. Because software that doesnt interact with the operating system in any way is alwaysbetter, right?

Quote from Tweaker :As far as I know, Ian.H from dSRC LFS team has made an LFS mod for rFactor. This could very well be from his mod. There is a dS autos skin in that zip somewhere too. This could be his conversion... but I think he only did the XRT.

I doubt very much that this is Ian.H's work, its very shoddy indeed and Ians work has always been very high quality.

The model in rFactor doesnt even have any glass, they seem to have lost all the glass components in the conversion. Also the car only has street tyres, so I'm not quite sure how it counts as an FZR. I suspect its just the physics from an existing car with the fzr mesh tagged on.

As I read the extract from the license agreement, it is fine to do this, provided LFS is credited. It would certainly be interesting if someone did a serious and detailed conversion of an LFS car to get the most direct comparison possible.

Also, I'm pretty sure there are some GPL and Racer versions of LFS tracks knocking about which havent been stamped on.

I think really that what you are asking for isnt really possible, as a SPR/MPR viewer would basically have to contain the entire LFS engine, and load all the same resources, so I cant see how it would be any quicker.

However, what would be really helpful, is if we could use windows file associations so that when we double click an SPR/MPR it loads LFS and plays the replay. That would be really helpful, I must admit I never bother to watch replays people post on the forums because I cant be doing with the hassle, but if all you had to do was download to desktop and double click, it would be much easier.

Just to confirm that I wont be able to make it. Just got back from holiday and time and money are in short supply at the moment.

Have fun guys, maybe I'll make it next year

You have to say my name three times you know, for faster service.

I last did a collection of car data straight after S2 alpha release so it might be worth you checking again, although I dont think the RAC has changed mass.

The RAF file output gives you total mass (inc driver and fuel) and also sprung mass (strangely including driver but if IIRC not fuel) so I had to do some raf outputs with known volumes of fuel, then take sprung mass and fuel mass away to get unsprung mass.

Again, I cant remember how we worked it out, but it does seem that unsprung masses are currently evenly distributed front to back.

Quote from jtw62074 :Right.

On top of this what's probably more important is the suspension geometry effects such as Sebastien mentioned. Even if the force centroid was in the middle of the contact patch you would get aligning torque feedback through the steering wheel due to caster angle and any kingpin axis that doesn't intersect the middle of the tire. Kingpin axis is just like caster, but viewed from the front of the car instead of the side.

So presumably if you had a tyre model that located the force centroid, you wouldnt actually need any 'aligning moment' graphs in the pajecka sense. You would just have a force centroid, and a steering axis/ground intersection point, and voila you have your aligning forces pneumatic and mechanical combined.

I think given that a) LFS appears to model tyre deformation as a integral part of the simulation, and b) scawen has never let on any details about how the tyre model works, we can probably assume that LFS has been doing it too.

It would also explain how the LFS tyre model seems to be 'different' to other standard pacejka models, and how it has at times done wierd things that havent just been fixed by a bit of value tweaking.

The first time I was in a sticky situation on the road, (which involved having to take to wet grass at 60 mph to avoid an oncoming car on the wrong side of the road), I instinctively aimed it for the gap, swept it round to avoid a tree, then corrected the rapidly swinging rear with a big handful of opposite lock, and found myself travelling the right way down the same road at 50mph before I even had time to think.

All of those instincts were learned from sim racing. I didnt have to think, or panic, or worry about how to control the car, it all just came naturally. So whether sim racing makes you faster on the track or not, I couldnt say, but it might just save your life .

Kid, you're obviously not capable of contributing in a productive way to an in-depth discussion about tyre physics, so why dont you just can it and go and troll elsewhere.

I dont think anyone in this thread is interested in petty inter-sim rivalry, we're just interested in tyre models. And NKPro uses the full pacejka calculated in realtime rather than from look-up tables, so is an interesting point of reference.

Yeah, aligning torque forces are really pretty small compared to the aligning forces caused by caster and inclination.
If you've still got an old version of LFS that lets you do it, set caster and inclination both to 0 and see how much force feedback you get. That would presumably represent the aligning torque in the LFS tyre model.

Its an interesting question, but I dont quite follow the logic of it having a big effect on handling behaviour.

Thats a genius rule. Its nice to know that you arent allowed to drive over or under another car in New Zealand.

I seem to recall that you can force LFS to use TCP packets only, maybe rummage through the config files or search the forum. I'm sure Scawen mentioned it a while back.

But if memory served, it was just there as a backup for people who couldnt get UDP packets through the firewall, there are performance problems I think.

Yeah, remember the relative volume of sounds depends very strongly on how close to you ears they are. So the sound 'source' for wind noise is all around you and particularly your helmet and surrounding bodywork. The main output source for the engine noise is the exhaust, which is behind you and pointing the other way.

The answer to the last question is get her hooked on some girly TV show like Lost or ER, but refuse to watch it yourself. That way whenever she is watching daft girly telly, you can race.

Although you do have to agree on some decent programs you will watch together, that way she doesnt mind too much.

I'm definitely interested in making is this time. It would depend on time and date and cost and all that though. But put me down as a provisional

Hmm. Not at all convinced by that Don. EPS's are definitely not 'rasterised' already if the original information was vector based.
Of course EPS's can contain both vector and raster information as they are used for print layout.

EDIT: Yeah, i've just imported the EPS into Flash MX and its as editable as and editable thing.

I presume you are opening LFSEPSvecto.eps from the vector subfolder.

But you seem to be opening it in an image editing program, which edits images, not vectors. When photoshop or paint shop pro is asked to open an EPS file, it rasterizes it into a pixel based image, so you can no longer edit the vectors.

You need something like illustrator to do vector editing on EPS files.

EDIT: Apparently PSP does support vector file editing as well, but presumably you need to specifically tell it to open it as a vector or something. Maybe try 'import' or something like that.

LFS has nearly always had cheat protection. Certainly since late demo and S1 days. Its just getting more sophisticated.

Ah, well. If you have no phone line, and are too weak to carry your computer your only options are to either persuade the admins to open some ports or find someone with a mobile phone that will act as a modem.

Yeah, sounds like your best back is to crack out the old 56k modem, provided you have a phone line.
Then just sign up for one of those free, pay-as-you-go dial up providers.
