Reducing network latency

I recently read an article about Microsoft''s Age of Empires game and how they handled network latency. (Btw, this applies particularly for 2D graphics). Doing it in 3D might differ a bit. A few methods were outlined. To summarize, their method involved the sending of data packets from client to server to synchronize player status with the server and all the other clients connected to the server WHILE the animation frames for that player are being drawn. This would therefore lead me to think : If I have longer animation cycles,or prolong a player''s movement (Eg: say, holding the up key on the keyboard for one second moves the player 10 pixels forward in a networked game while it''ll only move a player 5 pixels forward in a single-player game in 1 sec)would that directly mean I have more time for the server to synchronize with the other clients therefore reducing the chances for network latency ? Is this the way how games like networked FPS-es are being done?) Just another thought : The article also recommended the transmission of user input (mouse clicks, keystrokes), instead of game object statuses. In this sort of paradigm, basically everything in the game will have to abstain from using pure randomly generated numbers, since every game object on every machine in the same world would have to respond in the exact same way to the user input. I find this a pretty efficient way of reducing packet size.. But I''m not sure about the kinda problems you''d encounter with re-synchronizing unsychronized clients. Anyway, anyone with any idea on my question in my 2nd paragraph,pls let me know. Thanks! Regards, Eddie for (i=0;i<=forum_replies;i++) { if (reply.useful==true) { my_knowledge++; } }

Well, .useful is the boolean property in an array holding a list of Reply Classes, so I didn''t define it as a function. But then again, that would have become
if (reply->useful==true) {my_knowledge++;}

(btw, I''m also quite used to using curly braces...helps me see where the if statement ends)

I''ve decided to just drop that silly signature anyway.
lol..
Regards,
Eddie
