Re: [simspark-devel] [Sserver-three-d] rcssmonitor3d: Playing back logfiles in real time?

[H.Ebrahimi <hes...@gm...>]

Hi Hedayat and all,

I have created a new patch, adds the speed controls, fixes a bug, and
tidies up the code.
The fixed bug: when the log player hits the end of log file, it cannot
play backward (using the 'l' key). After applying the patch, when the
end of log file is hit, the player pauses and resets the eof bit of
the input stream. Thus, user can hit 'l', and then 'p' to go backward.

If it's possible please a more active developer tests this patch :-)

Hedayat, is the problem you mentioned about the log recorder and
multi-threading fixed? If not, maybe I can give a hand.
