Hi Radu...

first of all thank's for the quick implementation of the interface... I =
really needed it in order to continue my experiments...

I tryed to run your code and it works perfectly... but if I try to use =
an PlayerGraphics2dCmdPolyline object with the number of lines smaller =
than 64 it simply does not show anything... I tryed to show a simple =
line on Stage with only 2 points using the same idea you used in the =
example and it did not work... Then I hacked slightly your code (see =
bellow) in order to print only part of the circles and it did not worked =
as well...

I then tried to solve the issue with the class =
PlayerGraphics2dCmdPolygon but I had the same problem. I tried to went =
through the source code of playerclient and the graphics2DInterface and =
it seemed fine to me...=20

Another thing that you might want to have a look in the class =
PlayerGraphics2dCmdPolygon is that if you do not setFill_color it gives =
an exception, when it could probably use a default (transparent?) =
value...

Thank you very much=20
Regards...
Hugo

Hi Hugo,

Sorry I'm only delivering now, but I've been busy with other things=20
during the weekend. :( Hope it's not too late for your project.

Anyway, I just committed the code to CVS, so it should be available for=20
you in the morning. Please ignore the WSNInterface for now, as I'm still =

working on committing the new wsn interface and drivers to the Player=20
repository first.

I haven't had time to test it properly, but here's a "quickie" :)...
- Player/Stage 2.x from CVS
- started with everything.cfg
- and the following code compiled into Javaclient:
PlayerClient        robot =3D null;
Graphics2DInterface g2di  =3D null;

robot =3D new PlayerClient                 ("localhost", 6665);
g2di    =3D robot.requestInterfaceGraphics2D (0,=20
PlayerConstants.PLAYER_OPEN_MODE);

robot.runThreaded (-1, -1);

        g2di.clearScreen ();
        PlayerGraphics2dCmdPolyline p =3D new =
PlayerGraphics2dCmdPolyline ();
      =20
        PlayerColor color =3D new PlayerColor ();
        color.setAlpha (0);
        color.setRed (0); color.setGreen (0); color.setBlue (0xff);
        p.setCount (64);
      =20
        for (double r =3D 0; r < 1.0; r +=3D 0.05) {
            PlayerPoint2d[] points =3D new PlayerPoint2d[64];
            for (int j =3D 0; j < 64; j++) {
                points[j] =3D new PlayerPoint2d ();
                points[j].setPx ((float)(r * Math.cos (j * Math.PI / =
32)));
                points[j].setPy ((float)(r * Math.sin (j * Math.PI / =
32)));
            }
            p.setPoints (points);
            p.setColor (color);
            g2di.drawPolyline (p);
            try { Thread.sleep (100); } catch (Exception e) {=20
e.printStackTrace(); }
        }
---

Please tell me if it works and if you encounter any errors.

Cheers,
Radu.
