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

Hi All,

I have commited the current version of the split-screen
developments in the r1-3-x branch of the CVS tree.
I also made packages in <http://torcs.org/tmp>

Be sure to get also the cars packages as they contain
mandatory texture files for shadow.

The TORCS-1.3.0-data-tracks-base.tgz contains a new track
(22 km long) yet unfinished, but it is used to test
the framerate with long tracks (60484 vertices)

Have fun,
Eric.

the race->"racetype"->configure menuentry don't work (for every
racetype).
that means i can't select multiple human player for the race;)

Just select multiple players in the race drivers selection.
but if the race config menu is broken, that won't be possible
to select the drivers.

What do you mean exactly by "broken" ?

Bye,
Eric.

Ok, now it works, but i can't find the multiplayer configuration... and the race config menu entrys are broken;)

I forgot to indicate how to install the data:

"make datainstall" and it should work.

hi,

i have some problems with the cvs version...
it compiles fine, but it don't run:(

wintermute:/usr/local/share/games/torcs# torcs
/usr/local/bin/torcs: line 50: 11030 Speicherzugriffsfehler  ./torcs -l
$LOCAL_CONF $*

sorry for the german local;)


and finaly "make install" didn't installed the data,tracks and cars to
"/usr/local/share/games/torcs" (i had to copy it by hand).

Sorry for the problem, I commited correctly this time,
you'll have to update src/libs/tgfclient only to have
it compile.
Or better a "cvs update -P" under src/libs will also
remove unused directories...

Sorry for the incovenience,
Eric.

PS: I sent the mail to the devel mailing list because
other people may be interrested.

Hi,

I just commited in the CVS tree (branch r1-3-x)
a "playable version" of the multiplayer.

You can now configure the controls separately for each
player and the screen will split automatically according
to the number of players.

The smoke and flames bug is now fixed.

The camera and viewed car selection need some work yet.

I tested the 3 players mode with two of my sons with
2 wheels and one joystick (all USB) on the PIII 800 Mhz 1024x768
it was smooth and we had a lot of fun.

Bye,
Eric.

Hi all,

I have started a local multiplayer mode (the network
mode is a little harder than expected...) with split
screen.

The first "pre-alpha" version is under CVS
(branch r1-3-x), you'll not be able to play yet
but you can see the robots in the screens.

Screen shots are there:
<http://torcs.sourceforge.net/sections.php?op=viewarticle&artid=25>

Note that the robots viewed in the screens are the first
ones, and you'll have to select at least 4 robots for
a screen splitted in 4 parts.

to split and unsplit the screen use the '[' and ']' keys.

There's a lot of modifications to do yet, like
fix the smoke and flames, configure the players,
fix the camera movements, select the cars viewed
in the different screens...

Comments are welcome as usual ;-)

have fun,
Eric.

In TORCS it is possible to beat every robot at this time (after 10 to 20=20
training laps, a steering wheel and several thousands F1-simulation laps=20
experience...). The robots are doing a good job as long as they are=20
alone, but in racing situations they are at the moment simply too=20
stupid. The reason for that is not the lack of ideas how to improve it,=20
but that you have just very few computing time to make your decisions.

AFAIK they are using manually designed paths (waypoints) and are=20
cheating what the physics conserns.

trajectory:
-----------
- static path planning from your K1999, clothoids or splines.
- acceleration and brake is computed according to my TORCS robot tutorial=
=2E
- following the path: controlling the distance of the center of gravity=20
=66rom the path and the angular velocity, steer toward a point on the pat=
h=20
ahead of the car.

collision avoidance/overtaking:
-------------------------------
- check every car near mine
- try to predict the position of the opponents with several hypothesis
- select the "weakest" opponent for overtaking
- plan a path to overtake it (spline, it needs to be cheap to compute)
- check if the path is on the track, else reject it
- recompute allowed speeds if the path has been changed
- check for possible collisions, modify the allowed speed on these locati=
ons

letting overlap:
----------------
- check if opponent behind me has more laps
- if yes, start a counter, increase the counter if the opponent stays=20
within a certain range, if it falls back decrease the counter
- if the counter exceeds a limit, let the opponent overlap (drive on 
side till it passed me)
- if i manage to lap back "penaltise" the counter of the opponent to be=20
able to lap back if i can drive faster (else i would let it overlap=20
again as soon i overtook it)

pit stops:
----------
- path is a spline to the pit
- it is not that easy to stop on the point:-)

cool:-)
