[Java-player-users] simulation clock

[<sa...@sf...>]

I am developing a simulation using Stage and have run into a problem.  With
the old C++ client, it was very easy to get the simulation time.  However, I
can't seem to find a way to get the time since start of simulation using the
JavaClient.	

If there is a way, does anyone know what it is?  If not, can anyone point me
in the right direction on how to add this feature to the JavaClient?

Thanks for any help.

Sarah

I haven't looked at that one yet... If possible, take a look at the C++ client and see 
where that information is coming from, and then we could try to replicate it into Javaclient.

Due to time constraints, I am not able to do too much for the project right now, but I can 
definitely offer pointers and supervise.

I'll probably take a look again at the whole thing after we release Player 2.1, so having 
a list of "to do" would be neat, so I know what to upgrade or fix or... :)

As always, contributions are more than welcome!

Cheers,
Radu.

I did something similar not long ago:

Each header does come with a time stamp since the start of the simulation,
my solution was to simply record the most recent time stamp.  The best
position to do this seems to be in "read (int interf, int index)" in
PlayerClient.java, after the line:

    header = readHeader ();

you could add something like:

    if(header.getTimestamp()>currentTime)
    {
        currentTime = header.getTimestamp();
    }

then a getter method on currentTime in PlayerClient would allow you to get
the latest time.

I have attached my version of 
http://www.nabble.com/file/p12410309/PlayerClient.java PlayerClient.java . 
Its not exactly the most eligent way of doing this since PlayerClient
shouldnt realy be storing this type of information but it works.

Let me know if you have any problems

Thanks

John

Thanks John. Could you generate a patch against SVN ? I could commit it to the official 
repository afterwards.

Cheers,
Radu.

[John O. <joh...@gm...>]

sorry it took awhile but been busy.  Here it is(
http://www.nabble.com/file/p12634944/timestampPatch timestampPatch ), you
should be able to apply it by:

patch -p0 < timestampPatch

from the directory above the javaclient2 directory.

thanks

John
