[Java-player-users] Position and Laser interfaces conflict?

[Hugo G. M. <hg...@es...>]

Hello...

I've tried to make a small java class in order to understand the way the
interaction between the java client, the player and stage works.
So far I manage to get information about some sensors and move the robot
around... However I found a problem that I don't understand why it
happens... When I run the code below I have the information about the
position of the robot updated every step... And that is OK... But when I
uncomment the (apparently innocent) LaserInterface line I stop having that
information updated and it prints always the same position. Can someone help
me please...

Thanks...

package javaclient;

public class Test {
   
   public static void main(String[] args) {
     
     String hostToConnect = args[0];
     int portToConnect    = Integer.parseInt(args[1]);

     System.out.println(" Host: "+hostToConnect+"  Port: "+portToConnect);
     
     PlayerClient robot = new PlayerClient (hostToConnect, portToConnect);
     PositionInterface ppd   = robot.requestInterfacePosition(0, 'a');
     
//     LaserInterface    lpd   = robot.requestInterfaceLaser(0, 'a');
     robot.runThreaded(-1, -1);
     
     for(int i = 0; ; i++) { 
        robot.readAll(); 
 
        for(int j = 0; j < 100000000; j++){} 
         
        ppd.setSpeed(100, 0);
        System.out.println(ppd.getX() +  " " + ppd.getY());

     }
  }
}
