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

[Kenneth M. <km...@at...>]

I'm using Javaclient 1.6.4 (Player 1.6.4, simulating bot in stage) and
having some problems getting either odometry data or the simulation 2d =
pose
back.=20
=20
When trying to get odom data (readData then getX, getY on the position
interface) I keep getting garbage values (values jump all over the =
place)
without even moving my 'bot from its start position.=20
=20
When I try to use the simulation interface to get back a 2dPose and look =
at
the 'bot's co-ords that way, it just sits there waiting for a response =
(did
a get2DPose, kept waiting on isPose2DReady).=20
=20
At one point, I managed to get the simulation interface to connect to =
stage
(somehow; still not sure how) and got an error like "warning: No =
permissions
to configure device lf:0"....?   I read somewhere in the P/S mailing =
list
that that error could be due to an old version of Player or Stage, but =
I'm
using the latest release...
=20
Could someone please post a clear, working code example of how to do =
either
or both of these things (retrieve odometry data and retrive a simulation =
2d
pose)?=20
=20
Thank you

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

Try adding player.runThreaded (-1, -1); for a kick.

Hi
Thanks alot, will try that now... I was left under the impression that 
the way I was doing it was the standard way from the examples in th "How 
to..."
I saw this threaded stuff in the source code but could not really figure 
out what it would change...


Good luck in Munich, I'm from Germany myself :)


regards,
Ole

You have several client<->player modes. Check

details.
