I have no idea what the problem is with that, but I guess it's an alsa 
or oss problem. If possible try the other driver alsa<-->oss and/or try 
a newer version. If you find a solution please post it.

I guess you have not changed the starting list before running your first 
race and you have not all robot packages installed. Deselect all drivers 
in the (left) list and fill in opponents which really are installed.

That is just for PPC (power pc), plib 1.6.0 should work with x86 out of 
the box.

Hmm, I guess you can safely ignore that.

Hi,
When I compile TORCS, I am getting an error that Plib 1.6.0 was not detected
and when I execute TORCS, I am getting this:
 
WARNING: slScheduler: Needs a sound card that supports 8 bits per sample.
linuxModLoad: ...  /home/lib/torcs//drivers/cylos1/cylos1.so: cannot open shared object file: No such file or directory
Pb with loading /home/lib/torcs//drivers/cylos1/cylos1.so driver
No driver for that race...
 
From TORCS FAQ, I found for such type of errors, 
slDSP: open: Device or resource busy
WARNING: slScheduler: soundcard init failed.
it says to apply the patch to plib 1.6.0. After that you need to recompile and reinstall plib and TORCS. 
 
I installed the plib 1.8 and plib 1.6.0 versions, it didn't work.
I am getting the same message of plib 1.6.0 version not detected.
 
Another problem, I have is the directory link has double slashes torcs//drivers/ 
 
I will appreciate any help.
 
Thanks!

I have made a new road track, which has some nice textures and a
rather large shadow file for environment mapping, should be in
torcs/data/tracks/road/ole-road-1

I probably need to smooth out the terrain's 3d data because the one
generated with trackgen from the elevation file tends to create
strange subdivisions.

Hi Mihnea

>I was wondering if torcs supports force feedback. Thanks,

No. I think it would take 5 hours to build a prototype and up to 30 hours
for a nice implementation (menu for adjustments, effects, portability, etc.).
I think various people already implemented some kind of force feedback for
TORCS, but their code made it never to us (e.g. look at the link on the end
of the FAQ):-(

Hi Mihnea

> Does anybody know if it is at all possible to put animation type files for textures? Basically what I need is to look at a wall that has a texture on it and see it change. I don;t care what file format the texture needs to be in to be animated as long as I can animate something. Any help would be greatly appreciated

No, I'm quite sure that plib does not support that without further work. 
You have to implemnent it yourself.  Depending on your animation type 
you can:
- Put all pictures to textures or better into one big texture if 
possibe. Depending on your choice you can animate with changing the 
texture object or the texture coordinates. The latter choice is better 
(look for background information on several OpenGL 
sites/discussions/papers/newsgroups, opengl.org, nvidia.com, ati.com, ...).
- If your animation is large (e.g. a movie) you have to generate a 
texture object on the fly for every movie-frame. On PCI and AGP cards 
this is quite an expensive operation, I heard PCI-Express is better for 
such kind of operations (I have not touched such a card yet). The issues 
are the bus bandwith, latency and the texture caching of the card.

A partial example for what you are looking for is the rear mirror, you 
have just to get the texture not from the framebuffer (e.g. if you would 
like to implement a huge display for the spectators it would work like 
the rear mirror).

Bye, Bernhard.

Too bad :-( it's the PLIB loader that is used for that.
well you'll have to add some additional parameters to the loader
in order to use your own image loader, check the ssgLoaderOptions
for that.

by loeader do you mean grutil.cpp? If in my ac file I define a texture =
texture1.test, I want to have a loader that interprets that as download =
this texture from www.mike.com?texturename=3Dtexture1   That's what I'm =
interested in doing: intercept the texture loading process for my own =
recognized extension

let say that your track uses road.rgb as a texture as defined in the .ac =
file.
the loader will search first in the track directory, then in the =
data/texture
directory, and if everything fails, you can read a parameter in your xml =
file
with the URL to search...
look in the code for the parameters retreiving, it's not so complicated =

I merged my maintainance code with the latest torcs code. This does
not include any new features, but merely bugfixes of older ones and
slight improvements in mature modules, such as the grsound module.

Please do test, as this code changes interfaces/car.h and
modules/graphic/ssgraph/grmain.h - among other things.

The learning library is not touched. I think maybe I should move it to
the robottools directory, it seems nicer. My work on the
learning led to the development of a new learning technique, so I am
busy trying it out on some experiments and writing a paper
about it, though I have not tried it yet on TORCS. (still toy problems
like controlling an inverted pole and stuff).

However as far as TORCS is concerned, and with respect to learning, I
am not sure if it is good to combine learning with an already good,
but very constrained robot, or with a mediocre but quite adaptible
one - hey, maybe that's a good research topic.
