RE: [Java-player-users] InterfacePosition2D

[Marques, H. G <hg...@es...>]

Hello...=20

thanks for the reply... I've double checked my code and there is no =
refences (not even in the classpath) to javaclient1.6.5. I already =
manage to control the robot's movement but the method setSpeed(int,int) =
is in my code of javaclient2:

    public void setSpeed (int speed, int turnrate) {
    	PlayerPose pp =3D new PlayerPose ();
    	pp.setPx (speed);
    	pp.setPa (turnrate);
        setVelocity (pp, 1);
    }

I agree with you that it should not be there has it looks compliant with =
the previous version but in fact the speed and turnrate are different =
now...

I also tried to investigate a bit further the ClassCastException and I =
believe that the mistake is on the player (or stage) side. It seems to =
me that  there are variables not properly instantiated and that is =
somteimes it works and sometimes don't... the PlayerClient code looks =
fine to me...=20

actually the error only happens when I receive only this message from =
stage:
Player v.2.0.0

Rather than:

Player v.2.0.0
selected devices [localhost:6666]:
 6666:position2d:0 (stage)
 6666:sonar:0 (stage)
 6666:laser:0 (stage)
 6666:blobfinder:0 (stage)
 6666:fiducial:0 (stage)

I hope this helps... once again thanks...
Hugo

This is not good... setSpeed was removed in Javaclient2 completely!=20
Instead we have setVelocity (PlayerPose,int). PlayerPose has float=20
structures so no need to send integers. Are you using a mix between=20
Javaclient 1.6.5 and Javaclient2 ?
