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

Here is a patch to play with.
Correctly combined longitudinal, lateral, and yaw tire friction forces.
(realistic and predictable vehicular response where the rubber meets the road)

Correct.

Probably.

torcs-1.3.5-test1
'openal' has the problem.
'disabled' and 'plib' work correctly.

torcs-1.3.7
both 'disabled' and 'openal' have the problem.

Hi David

So, to recap, just to make sure: It freezes only under gnome 2, when you 
do the same thing e.g under KDE it does not happen?

Hypothesis: KDE and Gnome do not use the same sound daemon, the Gnome 
sound daemon in combination with torce causes a hang somehow.

Can you test this? You could try to disable the sound in TORCS and see 
if you are still able to make it hang (as it sounds it is "a piece of 
cake" to reproduce it on your system, is it)? If you take an old version 
of TORCS (which had the plib option), does it happen with plib and 
openal, or just with openal?

Thank you for your support.

Kind regards

Bernhard

Here are two more scenarios:
1) I crashed into olethros-6/car4-trb1. When olethros-6 hit the pit wall
    TORCS froze. This is with Dirt-2 as mentioned above.

2) Select: Quick Race (previous tests also), car6-trb1, E-Road, semi-pro
     (t-bone pit wall from track-side using Gnome2 desktop freezes TORCS)

Thus any car/driver hitting the pit wall on any track may freeze TORCS
when using the Gnome2 desktop. I have never froze TORCS by colliding
with anything other than the pit wall.

 HELLO
I am experimenting the simulink robot plugin for TORCSfound in https://github.com/VerifiableAutonomy/TORCSLinkwhich is an interface between TORC and MATLAB The problem is that I am enable to ACC example. Afterfollowing the first steps on the "read me" file and  installing the Motorway track, the driversmatlab 0 and matlab 1 are  nowhere to beadded to the race in the TORCS menu.I am using visual studio 2013 and matlab 2016b. Thanks in advance for any help.

I can reproduce this problem with 1.3.6 and windows. 
I also remember seeing the problem on linux with earlier versions of 
torcs. 

The best way to reproduce the problem is to keep the throttle open 
and adjust the steering to both extremes while contacting the pit wall. 
You'll need to repeat this with the car at differing angles to the wall. 
I just used dirt-2 with the peugeot 206 to reproduce the problem. 

I've never seen this problem under normal game play conditions.
