i made a couple of tutorial once. probably way out of date though.....buy might help you get started:

well you can use the pd objects, netsend and netrecieve i think they even have a simple chat server using netserver implementation in there. I have written a Java server that works in conjunction with the netclient object. the reason i am doing that is because i can write a multithreaded server.

basically you need to know a little bit about sockets to make it work.

so this thread is kindof a good place to ask a question. I have a working pd client but I am tring to parse out results from my object server, needed to manage the OCS data coming from my TUIO server.

since TUIO really just builds on top of OSC (it took me some time to understand that you really mean "OSC" when you write "OCS"; there are so many abbreviations and acronyms out there that you have to be careful,...), why don't you just use OSC-objects?

there is this nice set of externals from mrpeach: net/: a collection of objects allowing you to open UDP or TCP/IP ports as client or server osc/: a collection of objects that parse the output (or input resp.) of the net/-objects as OSC-messages understandable by Pd.

afaik they are part of pd-extended. if you are not using pd-extended, get them from ./externals/mrpeach/net and ./externals/mrpeach/osc (both in the pd-repository at sourceforge)

here is my client patch....

http://www.newobjectivity.com/downloads/pd/tuio_netclient2.gif

hmm, this is not really a patch, this is an image :-)

since Pd patches are usually very small text-files, it often makes sense to send the patches themselves instead of screenshots of them.

it seems the data is coming from the server ok...

afaik, [netclient] (as well as mrpeach/net's [udpreceive]/[tcpreceive]) will output binary data in the form of lists of byte-values. you will have to parse them to make sense. otoh, your output does not seem to be binary-data in form of byte-lists. it seems to be binary data interpreted as pd-messages. OSC is a binary protocol.

so this may be a misunderstanding. I am writing my own server that intercepts the OCS events, that all works. what I am trying to figure out is if i wanted to send out messages to net client for instance a string that was something like id 56; x 200; y 300; rot 0.923; what would I need to do to parse the netclient result.

I have tried [route x]-----[unpack $1] but that doesnt seem to work, but when i print the message using [print client1] it prints it just fine.

thanks a bunch, OSC it is, on port 3333, from the reacTable TUIO server.

I figured out that I needed ";\n" on my messages for the router to figure them out.

here is my netclient in PD, i will be making my server available also when I get that darn BLOG up.

might be a problem with the parsing of your string. when you send a message to Pd (e.g. [netreceive]), it will parse the string received and try to interpret it as a pd-message. e.g. the string "id 56" will be split into a symbol-atom "id" and a number "56".

if your string is somehow "weird" (e.g. because you send "56,4" instead of "56.4") Pd's built-in parser might parse the string in an unexpected way. (e.g. "56,4" will become a symbol "56,4"!)

[netclient] is an external, probably it uses some broken parser.

2 suggestions:

• if you really mean OSC intead of OCS, then try sending OSC data to Pd

from your server, if that is feasible.

• if you don't need a bidirectional connection between your server and

Pd but are happy with a unidirectional one, use [netreceive] instead; this object is built-into Pd and certainly better tested.
