Just watched them, I love it, the explosions are very good and the collisional should be pretty efficient! As I said in the comments I can't wait to see more, seeing other people get things done with their games makes me want to continue with mine

How are you managing networking? What library? Or is it built in to pyogre?

I'm using python's socket object, no fancy stuff there. I have some classes which make packets/messages for me, I send, I recv, thats about it. The Client + Server are both multi-threaded (Sorta, Python's GIL means its fake but yea...). One thread does game processing, one thread does network handling.
Why not use something like Twisted? Well, I started this project with no networking experience, and no 3D experience. In order to properly train myself in those two arts I tasked myself with creating a network game using sockets and OpenGL. I swapped OpenGL for Ogre after my first prototype/version for perf. But the networking stuff honestly hasn't become an issue sufficent to warrant outsourcing to another lib. Python may be slow, but its not WAN slow. And the messages are all my own, so I know the size/format of them, I don't think Twisted could make them much more efficient.
Thats pretty much it at a high level, are you interesting in specifics?

Well could you maybe tell me how you learned to use pythons sockets? If it was through the docs, just let me know. I tend not to look at them unless necessary.

Programming Python, Chapter 10, apptly named Network Scripting.
Found this code in the python docs for the "socket" lib
http://docs.python.org/library/socket.html:
Server
Code: Select all
# Echo server program
import socket
HOST = '' # Symbolic name meaning all available interfaces
PORT = 50007 # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()
print 'Connected by', addr
while 1:
data = conn.recv(1024)
if not data: break
conn.send(data)
conn.close()
Client
Code: Select all
# Echo client program
import socket
HOST = 'localhost'
PORT = 50007 # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
s.send('Hello, world')
data = s.recv(1024)
s.close()
print 'Received', repr(data)
Took that piece of code, and just kept iterating on it.

Well thank you for that, should come in handy should I also decide to make a python space game with
the same graphics, story, items, and users as you completely custom content.

Sounds good, its a race!

By the way, im looking at amazon for 'programming python' and I was wondering, do you have the third edition, or the regular?

I've got the second edition, circa 2001.
