Hi,

On certain tracks, like alpine 2, the points (car) in the map look shifted:
they don't correspond to the
place in the track where they should be.

Any ideas?

    Albert.

Yes, now it creates 3 .ac files, but trying to use my track it says:

WARNING: grscene:initBackground Failed to open shadow2.rgb for reading
WARNING:         no shadow mapping on cars for this track
/usr/local/bin/torcs: line 52:  6889 Segmentation fault      (core

So I tried to copy shadow2.rgb file of another track, but:

/usr/local/bin/torcs: line 52:  6965 Segmentation fault      (core
dumped) $LIBDIR/torcs-bin -l $LOCAL_CONF -L $LIBDIR -D $DATADIR $*

Hi Enrico

Open the XML file with a text editor and do the following:
change     <attstr name="category" val="" />
to     <attstr name="category" val="road" />

That makes it work for me.

I hope it helps

Hi Olaf, Hi Vicente,

I also think that the torcs track editor should be available 
platform-independent, like the old one used to be!

I'd love to test it, but since several years, I do not have any windows 
around.

:-)

Good to know someone is continuing the "track editor project",
but unfortunately windows only, why couldnt Sk. use platform-independent 
libraries?
Vicente, you suggested to run the app with wine,
which wont work at all because wine does not support the NET framework.
Could Sk. release the source code of his track editor?

Best regards,
olaf

A new trackedior is under development by Sk.
A beta version is available to download

You can read more an give feedback to the developer
of the program on the f1torcs forum:
http://www.s8.createphpbb.com/f1torcs/viewtopic.php?p=54&mforum=f1torcs#54

The beta version can be downloaded from:
www.megaupload.com/?d=HO6YX2OS

And to run the program you will need to:
* Install the . NET framewor (version 2.0)
* copy form the torcs sources the file
C:\torcs\src\libs\tgf\params.dtd 


"I started one in C# using OpenGL and the NET
Framework facilities. I wanted to know whether it
would have any audience among those interested in
track editing - I'm probably gonna work on it some
more anyway, but to do that final bit of "finish" I'd
really like to know that it raises some interest. I
ask this because I know of the Mono project, but as of
now NET mainly equates to "Windows only": would you be
interested in such a tool or fo you prefer Linux

A free differential allows the wheel to freely rotate at different 
speeds.  It's what front-wheel drive cars use (and what a lot of 
rear-wheel drive cars use).  A limited slip differential is almost the 
same, but it does not let the wheels rotate at _very_ different speeds.  
Depending on the situation, it might behave either more like a free 
differential or like a spool one.  In a spool differential, the wheels 
always rotate at exactly the same speed.

A couple of more differentials:
a locking differential has two states: free and locked (spool).  The 
change from one mode to the other may be manual or automatic, 
depending.  (It's usually manual in some 4WD off-road vehicles).

a variation of the limited slip differential is the viscous coupler 
(used in some places in torcs).

The ride height is just the ground clearance when the car is stationary.
Adherence is:
a) stiffness: how responsive the car tyres are
b) dynamic friction: how much friction you have when the car starts to slide
c) rolling resistance: self-explanatory
d) mu: maximum friction possible with this tyre

The car tyre friction curve versus speed is 0 at relative speed 0 (when 
the tyre moves at the same speed as the road).  It goes up really fast 
to mu and then down again to some value mu*dynamic_friction.  The speed 
it goes up with depends on stiffness.

Your suspension is too soft, or your aerodynamics are unrealistically 
strong, or your
ride height is too low.

Hi!
I'm trying to making a car, and I need some help for xml file. There are 
several things I don't know and I didn't find them in any tutorials I saw.

So:
A) What is Tq, in "data points";
B) The difference between Free Differential, Limited Slip Differential 
and Spool Differential;
C) What is efficiency for, in gears and differential;
D) What are Adherence and initial ride height in wheels;
E) How can I raise car height, because it creeps on the road at high 
speeds, without using Blender.

Can you help me?

Hoping I will finish my car soon,

Thanks for your patience,

Hi! I have a problem with encoding a movie. I captured a movie, and I
converted png images to jpg. When in command line I run

~/.torcs/captures$ mencoder -ovc lavc -lavcopts
vcodec=mpeg4:vhq:vbitrate=1800 *.jpg mf:// on:fps=25 -o /home/try1.avi

(I changed -mf to mf:// because when I ran command appeared:

-mf on has been removed, use mf:// instead.


So running the first command appeared:


MEncoder 2:1.0~rc2-0ubuntu1~gutsy1 (C) 2000-2007 MPlayer Team

And it didn't create the AVI movie. Could someone help me?

Hi David,

please try running

You *may* need the switch '--without-xrandr' too, but first try the

I think that the problem is that the ac format exported by blender it's a bit
different form the torcs ac file format (the "crease 30" line).
So to solve the problem you have to export the car into ac format that is readable by torcs you have to use the TORCS AC3D exporter. You can find this phyton script with this document. To install the script just copy the file ac3d_torcs_export.py to Blender Foundation\Blender\.blender\scripts. Now the exporter is available in the export menu.

You can download the script here: http://www.esnips.com/doc/973b475c-e048-4bd6-ba6a-badec703af65/ac3d_torcs_export

Moreover you can take a look at the track tutorial wher is explained how to Edit the ac file created with trackgen with 	blender http://usuarios.lycos.es/f1torcs/tutorial/index.html and http://usuarios.lycos.es/f1torcs/

By the way, if you add new objects the objects must have triangles, so convert squared faces to triangles (select the faces into blender and pres Crtl + T). 
 
Hope this helps to solve the problem.

Hi all,  im having a problem with a track im trying to build for Torcs.  the track worked fine after building it in trackgen,  but i wanted to change the texture of the landscape (im using the track to try out some design ideas before making a decent one)

As i said, the track loaded and played fine in Torcs,  then i imported the track.ac file into Blender,  changed the standard grass texture used for the landscape to snow,   then exported it to .ac file.    Now the torcs crashes while loading the track with this error:

I need to put better instructions for linux on that website.  You'll need
to create hymie_sc1 and hymie_sc2 folders under
/usr/local/lib/torcs/drivers,
and copy hymie_sc1.so and hymie_sc2.so to those folders.

The hymie bots (I presume you're talking about the supercars set?) aren't
part of the TORCS distribution.  You can download it from
http://locus.webng.com/cars.html.

Sorry, I can't help with the crash problem.

P.S. I have another smaller problem: I can't find hymie bots for 1.3.0. 
Could someone tell me where I can find them?
