I only have this, figured out by myself: (without guarantee)


array('650', '651', '660', '661')
array('AS6', 'AS6R', 'AS7', 'AS7R')
array('Aston Grand Touring', 'Aston Grand Touring reversed', 'Aston North', 'Aston North reversed')

hmmm, now it works here, too.
Victor seems to work on it.

thx, paXton

Hi smith!

As reported before, stats runs fine under linux with wine.
Today I switched from server mode to relaymode, which seems to work fine under windows, too.
But on my linux box I get this error.

LFS stats! v1.34 (c) 2004-2005 Alexander 'smith' Rudakov (piercemind@gmail.com)
WARNING: relay server mode is still experimental and not supposed to be correct!
Connecting [isrelay.liveforspeed.net 47474 30000 pw ]
wine: Unhandled exception (thread 001e), starting debugger...
WineDbg starting on pid 0x1d
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x40120c3a).
In 32 bit mode.

I tried the same exe and stats.xml. On windows it runs, on linux it doesn't work.
I would be happy, if you could take a look at it.

Thx, paXton

@all: thx for the quick answers.
I have to think about it, which technique fit my needs, or how acurate the results should be.

@Dygear: sorry, I understood not the meaning of all your posts, but I will complete the list later, too.

btw: is it right, that when a lfs dedi is relayed via the lfs relay server, the insim port cannot be used by another isim app?

jepp, now I have seen it.

But there might be some problems when clicking too much on the cam buttons, so that the two-cam modus sometimes doesn't work here.
I try to figure it tomorrow or so, and will report. I don't know if it has to do with the fast zooming in/out bug.

Quote from Frankmd :Here is v0.6 for you. Use it at own risk

It looks simple and works great. very nice.

But after some playing, I don't notice a difference between focus on one car and focus on two cars with the custom cam. Im not sure if it works here. On what should I look?

Maybe you could also implement a SPACE-keypress to cancel the shift-U settings on the screen while on customcam.

Hi all!

For some days I play somewhat with Insim.

At the moment I'm a bit confused, how to build up a live ranking table/list with the actual position of each driver in a race.

When a race restarts, I get the starting positions out of the IS_REO packet. But how do I know the position of a driver after a few laps?
To know the actual lap, I can count the IS_LAP packets, and if the IS_LAP of driver x arrives before IS_LAP of driver y, I could know, that x is in front of y. But is this the right way?
I want to know which driver is in front of whom in every second, or perhaps in every sector.
Must I use current path node? But then I only know if someone has overtaken another, when his node is higher than the node of the overtaken car.

Quote from Dygear :Also, do you know of a way of getting rid of the Shift+U's heads up display? That on a movie would kinda kill it

.

use SPACE, Shift-F doesn't work in Shift-U mode

Quote from the_angry_angel :For reference, you CAN run the LFS dedi on linux, with the following command,

nohup wine LFS.exe /cfg=setup.cfg > /dev/null & echo $! > lfs.pid

This makes it run on the background, any possible output is routed to /dev/null (afaik LFS doesnt echo anything to STDOUT anyway, but this is kind of a "just incase" thing), and the PID of the process is written to lfs.pid.

And IMO don't forget

/dedicated=nogfx

in the setup.cfg.

@Victor:

Quote from Victor :Kinda doubt it because the 4 bytes in a float have different meanings than the bytes in an int.

reading a float i have done like :

float File_FloatIn (FILE *fp) {
    float Float;
    byte *f_ptr = (byte *) &Float;
    for (int x=0; x<4; x++) f_ptr[x] = fgetc (fp);
    
    //printf ("READ FLOAT: %f\n", Float);

    return Float;
}

that way you put all the 4 bytes of a float directly in an actual float without shifting with bits and all that.

jepp, my shifting was totally bullshit. thx

@Stuff:

Quote from Stuff :I made an example in VB6 and I also get 0 for every DirZ. Not sure about the path structure but I guess if we both get it, its intended.

Source.. use as you wish

:boing:ahhhh...thx. I've also worked on VB6 yesterday and get it working too, but your source looks much nicer and more complete, so I merge it with my next. 8)

Quote from MonkOnHotTinRoof :
replace float dirX = ... with int tmpX = ..., then do
float dirX = *(float*)&tmpX;

that's it. thanks

But i always get dirZ=0 for every node. Perhaps i should check it with a hex editor.

Hi!

I think i need some help for parsing the .pth-files.

I originally want to use them in VB6, but don't know how. So I modified a dirty C source from an earlier project to show the values, which are stored in the pth-files. But then the problems began.

}

I don't think, the float values are right. But i have no idea how to read them correctly. Is it right, that the "z direction" in BL1.pth is always zero?

I'll be very happy, if someone could show me a hint, how to do it.
Perhaps some code snip sets in VB6 or C.

As you see, I'm not very familiar with C or VB6. Years ago I programmed a lot of command line tools in AmigaE and MaxxonBasic, but now i feel like a noob. 8)

BTW: Many thx @RayOK for his VB6 examples.
