So, I believe I have gotten presence to work. I committed a new file
called test_ogp_presence. It essentially just keeps acking the
packings it needs to and responds to a handful (with VERY GENERIC
message handlers) of needed responses (looking at Sai's old code,
thanks Sai!). I put a screenshot on our main page for old-times sake.
Now we have our own screen up there.
Very cool! I need to have a look at that code to see why mine back
then did not work ;-) I suppose I did not send all needed packets.
My recollection is that you just need to ack all incoming packets that
request acks. There are 2-3 packets you have to send first to establish
presence before the circuit is complete. 2 are required plus 1 optional
(3 required+1 optional?) and in order to make sure you have a good EQG
with the sim you have to send those with acks and wait for them to be
acked before using the EQG cap. Otherwise, it works only sometimes. Very
hair-pulling when it doesn't work.
The next step for the client library, I believe, would be to somehow
hook up some sort of input so that while presence is established you
could send commands to do (like teleporting). This way, we could see
things working live I think. Maybe this would allow us to see an
avatar teleporting interactively. It may be easy to get an av to walk
in a straight line or something too, but I dunno.
I started some client with threads in my sandbox. Well, maybe more an
experiment than a client. But as it uses threads it should as well be
possible to take commands and pass them to the correct threads.
See here:
http://svn.secondlife.com/svn/linden/projects/2008/pyogp/sandbox/trunk/sandbox/mrtopf/example1.py
It's pretty much the original example which does it all manually but
sorted out into threads.
There is also the ADQueue thread which calls the EQG of the AD regularly.
It's not pretty code at the moment though but maybe it's helpful.
cheers,
Moving around on the sim should be possible once you have full presence.
Not sure if ghosting (leaving off the optional presence-packet) allows
movement or not or if that only has to do with Physics. Changing avatar
position and the like would be a good first test for making sure our bot
is truly functional, but I think the most useful thing to test will be
group IM. Getting that to work should reveal more design flaws that
anything since you have to pull in data from UDP AND EQG to get it working.
