Hi there,
I am still looking for a way to program my network game (four players on four different computers collaboratively control the direction of one object, each is responsible to move the object in one of four directions.) I guess one solution would be a server-client approach. Each client sends a value to the server, the server collects the input of the four clients and returns the input of all four to each client.
I figured that using the Komhttpserver package I can easily run a server.
My problem is now is the communication between clients and server. How can I send a value from each client to the server and get back the inputs from all clients?
Thanks a lot Martin
This is how I run my server.

Have a look at HTTPClient examplePostArgs and HTTPClient httpGet: url
As an alternative you might want to have a look at some remote messaging tools like soap opera http://www.mars.dti.ne.jp/~umejava/smalltalk/soapOpera/soapCore.html or rST http://wiki.squeak.org/squeak/2288 or maybe even osc http://map.squeak.org/package/61f807be-83a3-4944-bfa1-686ddac7153c

Hi all,
thanks for the many suggestions. There does not seem to be THE way to do it. What would be the easiest way, even if that would be not the nicest solutoin.

right, also examples should be tested first... ;-)
Ok, with the following (replace upToEnd with contents and omit the closing of the (non)stream:
examplePostArgs | args result resultStream | args := Dictionary new. args at: 'arg1' put: #('val1' ); at: 'arg2' put: #('val2' ); yourself. resultStream := HTTPClient httpPostDocument: 'http://www.squeaklet.com/cgi-bin/thrd.pl' args: args. result := resultStream contents. Transcript show: result; cr; cr
it kind of works. Modulo that squeaklet.com is not there anymore so you don't get any specific answers. If I were you I'd probably go for the udp solution mentioned by others.
It would be great though to have some kind of Etoyish solution for your problem (think lightweight open croquet for etoys) with udp or osc or anything under the hood) so this is a very interesting question!

Hello again,
I am making some slow progress. Well, I managed to run an example :)
I run on one image the OldSocket example remoteTestServerUDP and on a second the remoteTestClientUDP. I hope that is the right direction so far. my transcript tells me that server and client endpoints are created, and some packets are sent.
I get the following message: 4000 bytes/packet, 117packets/sec, 2370 packets dropped.
he shouldn't drop packages, shouldn't he?
Further, the image running the server is not responsive any more (does not react to anything). Is that how it is supposed to work?
Thanks for your help. Martin

Hi Derek,
I have to confess I just want the application. I assembled a small program with squeak and was happy that I could do everything I wanted within minutes. (Drag and drop of morphs and some scripting).
Then I wanted to do that as a collaborative game and hoped that that would also be possible quite quickly. However, it turned out to be more difficult. So now I am stucked with network programing. I am simply interested in the result. However, if there is no other way I am also willing to learn how to get there.

Take a look at Scratch (http://scratch.mit.edu/). It has some networking built in (http://scratch.mit.edu/forums/viewtopic.php?id=9458) and there may be a new version soon. I think there are some multi-player examples that might help you.
Of course stick with what you are doing if it is going to expand on the idea but Scratch may help to quickly test the concept.
As for your current code it looks like you are pushing around ~4MBit/sec so maybe that explains the dropped packets and unresponsiveness. This is probably a lot more than you need for your purpose. Maybe you only need to send ~20 updates/sec max?

Also do check out the previously mentioned NetMorph (http://swikis.ddo.jp/NetMorph/17). The bit on "Remote Perform" looks like it will save you some work.

when I reduce the amount of data it does not lose packages. so, that is solved.
How would the netMorph integrate in the UDP approach? I am a bit overwhelmed by the many possibilities. and its difficult as a beginner to see through the forest. I go for the UDP approach at the moment and hope that I will get somewhere :)

In NetMorph you are working at a much higher level. I suppose you might create copies of the morph to be manipulated and migrate them out to the clients and possibly each client might push a dummy morph back to the server so they can centralise user input. It might even be as simple as each client migrating a morph to the next, which the client still controls. Close the loop and you have continuous updates. Experiment :-)
I have had NetMorph running here. The migrating of a morph between images is not instantaneous but once it is then remote calls should be quick enough.
I am a bit overwhelmed by the many possibilities. and its difficult as a beginner to see through the forest.
I know that feeling :-)
I go for the UDP approach at the moment and hope that I will get somewhere :)
Good luck!
Hi Derek,

How would the netMorph integrate in the UDP approach?
In NetMorph you are working at a much higher level. I suppose you might create copies of the morph to be manipulated and migrate them out to the clients and possibly each client might push a dummy morph back to the server so they can centralise user input. It might even be as simple as each client migrating a morph to the next, which the client still controls. Close the loop and you have continuous updates. Experiment :-)
I have had NetMorph running here. The migrating of a morph between images is not instantaneous but once it is then remote calls should be quick enough.
I am a bit overwhelmed by the many possibilities. and its difficult as a beginner to see through the forest.
I know that feeling :-)
I go for the UDP approach at the moment and hope that I will get
somewhere
:)
Good luck! _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

you may try simple Socket connections via UDP. ByteArrays make nice Buffers as ByteArray has methods to stuff in Floats, Integers and Strings.
The class to look at is Socket. On the class side newUDP will create a new UD socket, which you assign a port via setPort:
Receiving and sending is done via receiveUDPDataInto: and sendUDPData:toHost:port:
You query the receiving socket with dataAvailable before actually receiving data.
If you search the swiki or the mailing list archives for these method names you will find examples.
Cheers,
Herbert

Hi there,
I am still looking for a way to program my network game (four players on four different computers collaboratively control the direction of one object, each is responsible to move the object in one of four directions.) I guess one solution would be a server-client approach. Each client sends a value to the server, the server collects the input of the four clients and returns the input of all four to each client.
I figured that using the Komhttpserver package I can easily run a server.
My problem is now is the communication between clients and server. How can I send a value from each client to the server and get back the inputs from all clients?
Thanks a lot Martin
This is how I run my server.
