Re: [Java-player-users] Problems using Position and Simulation interfaces

[Nils O. T. <no...@gm...>]

I just did a similar post on the player mailinglist... readData() 
doesn't work fo r me either, but readAll() for the proxy works. This is 
an not fully working example but some code fragments of it taken from 
the stuff I'm currently working on:

//At startup
player = new PlayerClient("localhost",6665);
position = player.requestInterfacePosition(0, 'r');	//a, r or w

//now loop this stuff...
player.readAll();
//update the global data so every behaviour can access it
currentX=position.getX();
currentY=position.getY();
currentYaw=position.getYaw();
System.out.println("Position  (" + currentX + "/"+ currentY + ") Angle 
is " + currentYaw);

This is of course for the Odometry data... give it a try...
I'm using plauer 1.6.4 and latest stable stage &  latest stable playerclient


cheers, Ole
