Hey Kent,

Totally understandable about your shift in time usage.  I figure i'll take
on some of the scripting tasks but leave the important stuff like networked
pirate dice to you.

If anything becomes uber important and you dont have time to do it, i have
no problem takin it over so we should be fine (:

Ok, about the network stuff hrmms...

#1 - GetServerList: well first things first, i added the network script
functions to the script help documents.  Have you seen those?  If so were
they not too helpful?  If not let me know, maybe i need to document things

Anyhow, GetServerList is only useful for searching for existing servers.
 Theres another function for creating servers but you are right, you would
change the string to PirateDice and thats all you need to do to make it work
for pirate dice.

#2 - SendChat: yeah this is the only place it sends to the server.  For the
success thing, basically what thats about is every network function returns
whether or not it was successful.  If it wasn't, you should display an error
message to the player and then bail out of the game.  The reasons it wouldnt
be successful is like if they unplugged their internet cable or something.

#3 - OnNetworkMessage: This guy is called by the game whenever it receives a
network message from the server.  How network messages work is you send a
message to the server which consists of "MessageName" and "MessageValue".
 After it gets to the server, the server sends it down to all of the
clients, including the person who sent the message in the first place.
 OnNetworkMessage is called once for each message received so that you can
respond to the message (like if someone raised a bet, you can update the pot
size).  Everyone receives messages in the same order (:

Since messages have both a name and a value you can do something like all
chat messages have the message name "Chat" and all message values are what
the person typed for chat.

For when anyone takes a turn you might make a message named "TakeTurn" and
then have the message value be something like "call", "fold", "raise 10"

OnNetworkMessage also receives messages when players join or leave.

Also each network message (i think... going from memory) give you both the
name of the player, as well as a "PlayerID" which is a unique ID# associated
with that player (if its ever useful to know, this ID# is always the same
for the same player, it's like an account number).

Does this help at all?
