How to display the car in the video screen? about gym_torcs

[ugo-nama-kun]

Hi,

The car body and dashboards are usually omitted in experiments in deep (vision) reinforcement learning papers by Schmidhuber's team and Deepmind team. That's why I removed them from the screen.

Anyway, you can recover the car body by modifying 280th line of grscreen.cpp

    for (i = 1; i < s->_ncars; i++) {
        grDrawCar(cars[i], curCar, dispCam->getDrawCurrent(), dispCam->getDrawDriver(), s->currentTime, dispCam);
    }

You should modify i =1 to i = 0. After the compile, you will be able to see the car body.
i=0 represent the first car, that is the agent. And other numbers are opponent cars.

For car mirrors, you should uncomment 361-366 lines in grscreen.cpp

    /* MIRROR */
  /*
    if (mirrorFlag && curCam->isMirrorAllowed ()) {
        mirrorCam->display ();
        glViewport (scrx, scry, scrw, scrh);
    }
  */

To show the map, tachometers etc. I remember that we should uncomment appropriate methods in 841-845 lines of cGrBoard::refreshBoard in grboard.cpp.

void cGrBoard::refreshBoard(tSituation *s, float Fps, int forceArcade, tCarElt *curr)
{
    if (arcadeFlag || forceArcade) {
        grDispArcade(curr, s);
    } else {
        //if (debugFlag) grDispDebug(Fps, curr);
        if (GFlag) grDispGGraph(curr);
        //if (boardFlag) grDispCarBoard(curr, s);
        //if (leaderFlag)   grDispLeaderBoard(curr, s);
        //if (counterFlag) grDispCounterBoard2(curr);
    }

    //trackMap->display(curr, s, Winx, Winy, Winw, Winh);
}

Hi
Thanks @ugo-nama-kun and @yanpanlau for the wonderful codes and explanations. I have finished training and I'd like to record a video with some of the basic sensor readings like speedometer etc. Please could you give detailed instructions on how to compile after making the changes.

You should modify i =1 to i = 0. After the compile, you will be able to see the car body.
i=0 represent the first car, that is the agent. And other numbers are opponent cars.

I'm relatively new to linux and it was with great difficulty I got all these components to work. I don't want to break it . Everything is installed inside an Anaconda environment.

Thanks!

i changed i=1 to i=0 but how can i re-compile the cpp file?

i just did "make" at vtorcs-RL-color but it doesn't show car

@JungHY
You need to

make
sudo make install
sudo make datainstall

Do you reproduce the model which is close to the model given by the author？According to the modification suggestions given in other issues, I have been able to train the model, but the car does not run very well. The car often goes out of the track and cannot return to the track. Do you have any good suggestions?
