Hey Chris,

Could you perhaps shed a little light on what exactly you mean by fail all
the time?

Cheers,

Sam N.

Gytha for OS X

Hi

I would like to run Gytha on OS X but seem to fail all the time. Anyone that knows how to set that up?

Regards

Good job. Can you add phasers (middle mouse button), det, shield
toggle, cloak toggle, show ship's current speed.

I just realized I pushed some Chrome-specific code to the demo server.
 I've revised it, so the demo should now run correctly in up-to-date
Firefox and Chrome.  I don't have access to a Windows machine right now, so
I can't test in IE.  I have no excuse for not testing in Opera, though.

Socket.io uses the best possible connection channel available in the
browser (Websockets, then Flash sockets, then long-poll), so it should use
Websockets automatically if they're available.  However, anything less than
a Websocket connection will be far too slow to be playable, so perhaps I
should just switch to ws.  I'll run some tests and see what the best option
is.

I did indeed lift the architecture of the networking code directly from
Gytha.  I was fortunate that there is a Javascript implementation of the
Python struct packing library, so I needed to change very little.  For the
SP_ and CP_ message objects, I actually wrote a regular expression that
rewrites the Python code into Javascript syntax.  (

I've reviewde the code in git, I like it, well done.  I see how it
derives from some of my work on Gytha.

I'm interested in hearing more, do keep us informed.

Re: HTML5 Netrek, pre-alpha

Sven Neuhaus — 2012-04-04T08:26:27

Andrew,

interesting project, I'll definitely have a look!
I see that you are using Socket.io - is it fast enough? You may be better off requiring web sockets in the browser and using
the "ws" library: http://einaros.github.com/ws/

Also, I think in the long run we should add support for websockets to the netrek server directly… anyone feel like doing that? :-)

Btw the demo is not working at the moment.

HTML5 Netrek, pre-alpha

Andrew Sillers — 2012-04-03T21:34:11

All,

Just to let you know, I've been working on the browser-based Netrek client,
and I have a proof-of-concept up and running on Nodester.  It connects you
to continuum.us.netrek.org as a guest; right now you can do basic
dogfighting with torps (and phasers -- phaser-fire events are sent to the
server but they aren't currently rendered visually on the client).  It's
incredible sparse at the moment: when you die, you'll need to refresh the
page to get a new ship.

The demo is at http://trekproxy.nodester.com/.  If you can't join by
clicking on a race, try refreshing.

It runs pretty slow, but Nodester is a free (but awesome) service that
probably isn't providing the same level of bandwidth I'd get from a
commercial host (if multiple people follow that link at the same time,
expect it to be exceptionally slow).  I also plan to improve rendering
speed, so that might improve things a bit as well.

The code is also up on Github: https://github.com/apsillers/html5-netrek/.

So, it's not much to look at right now,

And now it is also available on Mageia, and will hopefully be available on Mageia 2, which is scheduled to be released may 3, 2012. Some two months to go.

Re: netrek-client-cow - Mandriva RPM release

Johnny Solbu — 2012-03-01T02:41:58

My first was SuSE 5.2 which came on a CD in a norwegian computer magazine in 1998.
I remember the title and cover as if it was last week: "A real 32 bits, gratis operating system" (Translated)
I har learned that Windows 9x wasn't a real 32 bit system. It was a mix of 16 and 32 bits.
So the ability to try a real 32 bist system atractec me. and th fact that it was free of charge, was what made me try it.


I went the other way around. :-)=
I had a Redhat 7.1 gateway, and was looking for something to test on my other computer. So I tried Debian 3.0-rc1, as Debian was supposed to be the best one.
It was the worst computer experience I've had to this date. The Debian installer back then was almost nothing but crap. t naged on and on about what hardware I had. On every posible hardware it found it asked me to manually enter/select the chipset, how much ram the system had, how much ram the graphics card had, and which chipset it was. And, I had no clue as to any of this, except what CPU and how much memory it had.

Zachary Uram — 2012-03-01T01:49:06

Heh, my very first Linux was Mandrake back in 1999. Wasn't very happy
with it so I moved to Debian. Does Mandriva have a Live disc I can
boot off of to try it?

Re: netrek-client-cow - Mandriva RPM release

Johnny Solbu — 2012-03-01T01:44:51

If one use the terminal: "urpmi netrek-client-cow"
Or one could search for "netrek" in the graphical package manager, and it will show up.

They might have to add a repository in order to find it, as not all packages fit on a 4.4GB dvd. ;-)=
The easy way to do that is to use the "Easy Urpmi" website and add one.

Thanks.  How does a naive Mandriva 2012 user install the package?  Is it
the same as installing a package on Ubuntu or Fedora?

Re: HTML5 Netrek client

James Cameron — 2012-02-29T02:00:21

Gytha also has packet dumping facilities, see --help.

Re: HTML5 Netrek client

James Cameron — 2012-02-29T01:59:13

Yes, in the file include/packets.h in the server source.

http://james.tooraweenah.com/cgi-bin/darcsweb.cgi?r=netrek-server;a=headblob;f=/Vanilla/include/packets.h


Not a good way.  Wireshark won't help much at all.  Build on my work.
After you've read packets.h, check the Python packet processing code in
the Gytha client.  There is very little to it.

client.py implements the TCP (and UDP) interface.

http://james.tooraweenah.com/cgi-bin/darcsweb.cgi?r=gytha;a=headblob;f=/gytha/client.py

client.py calls back into __init__.py for each packet type.  There's a
function for each packet type.  These packets are ordered in the source
in roughly the order that they appear on the wire, as it was a cyclic
development method that was used.

http://james.tooraweenah.com/cgi-bin/darcsweb.cgi?r=gytha;a=headblob;f=/gytha/__init__.py#l2670


Gytha has --tcp-only option on command line.

netrek-client-cow has something like it, but since I don't recommend you
learn from it, I'll make it harder for you to find it.  ;-}

Re: HTML5 Netrek client

Andrew Sillers — 2012-02-29T01:31:23

Collin: Absolutely, keeping the WebSocket server running would be just
about as important as keeping the actual Netrek server running.

James: Thanks for the TCP and RSA clarifications.  Is there any
documentation on the Netrek protocol?  If not, I'll just read through the
source for the Linux COW client and use Wireshark to see it for myself.
 Actually, is there an easy way to turn off UDP in COW?  (Or in any other
major client; I'm flexible.) Since I won't be using UDP, I want monitor the
net traffic of TCP-only behavior.

Thanks,
Andrew

Re: HTML5 Netrek client

James Cameron — 2012-02-29T01:18:06

G'day Andrew,

You need not be unduly concerned about the difference between UDP and
TCP, since the extra hop of the WebSocket server will more than cover
the difference.  Players will be at a slight disadvantage, but now that
everybody has fibre to the home, it won't be a problem.  New players
won't notice.  Old players won't want to change.  It's a non-issue.
Don't let it stop you.

You also need not be worried about RSA verification.  No server requires
it.  The server source does not include RSA support.  Several clients
already exist without RSA support.

So go for it.  Looking forward to your first implementation.  You should
post back here once you have something for people to test.

Re: HTML5 Netrek client

Collin Pruitt — 2012-02-29T00:43:30

The instant the WebSocket server dies, every person playing from the 
browser platform is disconnected.
