Re: [simspark-devel] NaN line segment positions

[Drew N. <dre...@ya...>]

Hi Yuan,

Unfortunately no, I can't give much detail about what caused it.  I was debugging another issue I saw between two teams using binaries from Iran Open 2011.  If you wanted to reproduce the environment, then you could use this configuration as much as possible.

Firstly, I'm on Ubuntu 11.04 x64.

I installed the server via:
sudo add-apt-repository ppa:gnurubuntu/rubuntu && sudo apt-get update
sudo apt-get install rcssserver3d
It's running with single-threaded ODE (until I work out how to get multithreaded working!)

The two teams were Karachi Koalas and Strive3D.  It was a 9 vs 9 game.  There was a bug in TinMan caused by a 'hear' message from Strive3D (completely my fault) which is fixed now, so you will need to replace their TinMan.dll with version 0.5.7 (debug build) from:

http://code.google.com/p/tin-man/downloads/list


With that setup, I see these occasionally during play, normally a few times per 300 second half.

It might be worth mentioning that my server install generally crashes at least once every game (within 600 sec) and that when it does, RoboViz encounters some exceptions related to "nan" strings as well.

    java.lang.NumberFormatException For input string: "-nan"

I hope that's helpful.

Drew.

Hi Drew,
Do you know which situation it happened ? For example did the robot fall on the line.
Thank you .
Best Regards,
Xu, Yuan
