If your intending it to be an internet based game you'll have to
cater for the lag (or slow responce) issues. If it's a network game
(ie. all computers on a local LAN) then this wouldn't be an issue.
Some of the big games (quake etc) have pretty complex algorthims to
counteract latency problems. If you look around the net you should
find a bit of information on how this can be achieved.
Considering a ping to another computer on the net can easily take 2
seconds (at best!) means that this is a real problem!
Can't wait to see the finished game! Sounds good!

As long as the server stores the connection information for each
client you should be able to send and receive to each client.
I never did write a demo program to show this. Anyway ... I think
euLibnet is better for multi-client server programs anyway.

In general there isn't a whole lot of discussion about euLibnet (or
euAllegro either!!!).
Communication libraries aren't ever going to be hugely popular as
not many people want to develop net/internet apps. There are a few
... but only a few.
euAllegro on the other hand I thought was going to be hugely popular!
It really is simple to write top quality 2D games using euAllegro!
I think I scared alot of people off by saying it wasn't complete
(which it isn't). Still top quality games can be made with what
already is finished.
HiRes support is probably the biggest "missing" feature. For me (a
simple 2D games writter 256 colours is heaps!!!) others do require
hires support though!
The number of example apps and my demo games show that pretty cool
demos and games can be made pretty simply!
As it turns out it is a huge amount of work to wrap Allegro. Allegro
has somewhere around 1300 functions!!!! Even if it only takes 10
minutes to wrap each one ... it is a huge amount of time. In reality
by the time you research the command, understand how it works,
implement it, test it and then document it, it takes alot of time
for just 1 out of the 1300 functions!

I didn't write any of the libraries, just wrappers to them. Still to
go find all the libraries (Allegro, Mappy, PPCol and JGMOD), compile
them all (not as simple as it sounds!), wrap them in a DLL and write
Euphoria wrappers was a huge job.
Thanks for the kind works but really they should be for the authors
of the above libraries. Allegro in particular is as good (if not
better) than most commercial 2D graphics libs).
www.allegro.cc is an excellent site to find out what people are doing
with Allegro.
As i've said before my interest has wanned a little in Euphoria ...
this is probably also because of a huge increase in my work
commitments. If anyone wants to become the offical maintainer of
any of my libs let me know.
