torcs-users Mailing List for TORCS - The Open Racing Car Simulator

This is mostly a MS VC++ question.*

I'm trying to follow Bernhard's robot tutorial in windows but I don't
know how to compile my new robot. (I've not used VC++ much before just
gcc)

I've got the sources and compiled Torcs fine and I can edit the bt
robot and recompile and race it without a problem.
 
I've run the robotgen script (on my headless linux machine) and got a
skeleton driver which I've put in C:\torcs\torcs-1.3.0\src\drivers\ but
I don't know how to import this into VC++ or get it built.

I can currently follow the tutorial by downloading the bt skeleton
robot from the end of the first chapter and replacing the finished
src\drivers\bt file with it, but I'd obviously like to create my own
robot.

I suppose if I could copy the bt robot within MS VC++ that would do the
trick but I can't even do that.

Help/ advice/ suggestions/ pointers to the friendly manual/ etc would
all be welcome thanks.

*Yes I'm sorry, but I've only got windows on this machine.

When running the configure script locally, it redefines LDFLAGS at the
point just before checking X11 libraries to -L$x_libraries. On my
system, this path is empty (not sure if that's good, but okay) so it
rewrites it to "-L". It then interprets the filename of the next test
as library path, figures it doesn't have any files to compile and
errors out. The error given is that my X11 library isn't findable.

Could you fix the script to not assume a variable to be set?

You can press F2 or another F-button to change the camera position. You can=

press F1 (during a race) for more information about the camera keys.

Hi,

Hi all!

For my master degree thesis, I have been working on a robot which is able
to learn to drive by itself. TORCS is used for about halve the experiments
(a much simpler Java simulation is used for the other experiments).

For those interested in more details:
A neural network is used to control the car. The weights are tuned using
Evolution Strategies (ES), which means that a reinforcement learning
approach is used. Different combinations of inputs are tried out, as well
as different coding approaches for the outputs. General driving skills are
learnt, so the robot is able to race also new, unseen tracks.

Experiments were also run using the Temporal Difference (TD) learning
framework that comes with TORCS. However, the results were bad.

The learning is quite simple, with no opponents, pit stops etc. So the
robot is not able to race against opponent cars!

TORCS was modified for the training in the following ways:
 - A "batch-mode" was implemented, where the graphics is disabled.
 - A common data area was shared between the robot and the rest of TORCS.
(A pointer was passed in the tCarElt->ctrl.lightCmd field). This was used
to communicate to and from the robot.
 - Initialization between races was made much faster, primarily by
skipping reloading of the robot, track and the simulation engine
(simuv2).

After training, the results were saved and the driving could be observed
using a "normal" TORCS.

Perhaps some elements of my thesis can be interesting if you work on
similar projects, I have an impression that also other people use TORCS
for this type of problems...

The thesis is available here:

My statement just tells that it is easily possible, but you need to adopt TORCS
for your requirements. Have a look at racestate.cpp and raceengine.cpp, watch it
in action with a debugger , then you will get an idea.

Bye, Bernhard.

Hello!

I have done some attempts on using reinforcement learning in TORCS. During
the this work, I have made some adjustments to the code. For the problem
of terminating a race, the following solution can be used:
 - If the robot wants to terminate the race, set the
tCarElt->ctrl.lightCmd to a specific value.
 - In raceengine.cpp, check the lightCmd value of the robot. Add a check
inside the ReOneStep() function, about line #550 in my (modified)
version...

Make sure the flag is reset before starting the next race!
Note that I use version 1.2.4

If you do not violate the licenses it is no problem. But take care, make sure
that you really understand them.

I've read various tutorials for designing cars, and I've never been
able to quite get one completed.  What I'm interested mostly in is
getting cars that I've found in Google Sketch-up to Torcs.  I've got
some tools to convert the various formats (from sketchup to kml import
to blender) but I'm not really sure what to do from there to prep the
car for torcs.  I'm a complete novice in blender (which is probably
why I'm not quite getting it), so if somebody has some detailed steps
I can attempt, that would be great.

Thanks,

The distribution I use has a patch for it, which can also be applied if you=
=20
install plib from sources: [1]. It is a patch against plib-1.8.4, but it ca=
n=20
be changed to be against 1.8.3 (although I don't know for sure if it still=
=20
works then, but I do think that the patch still works). For that change,=20
replace "1.8.4" everywhere in the patch file for "1.8.3" and patch it after=
=20
it.

To apply the patch, download the file and place it in /home/modi (in your=20
case) or the directory where you unpacked the sources in general. If=20
necessary, change the version number. Then, execute
"patch < plib-1.8.4-gcc41.patch" from the directory where the patch file is=
 in=20
(/home/mondi/, in your case).

Regards,

Mart

I uninstalled it and installed it as root where it wanted to go in usr/bin but now I still can't execute it. Why?

Hello this is Justin Breithaupt, i.e. usacomputertec

I want to use your project as a base and add to it. Do you think you could help me? My intentions our outlined here: http://thetuxproject.com/node/47.

We don't want to steel your cars. We would like the free ones though and to make our own cars for the game. What do you say? Please.
