Basically you'd just want to send the server the least data possible. I'd send only player coordonates and useful informations like health and such but make sure to send it only if it changed.

Code: Select all

if(healthChanged)
{
    // send information on the character's health
}
if(xChanged || yChanged)
{
    // send coordonates
}

That way you will minimize lag and low latency issues.

Learn to spell; it's client not clinet.

To minimize lag, don't send coordinates of the player each frame, but rather every 10 frames lets say. Then to get rid of the choppyness of not updating it that often you can make a function that takes the current location and goal, and infers their location for the 9 frames where they aren't getting info. It's how much major MMO's do it.

Most work with a series of messages and parameters for that message. For me, the client just sends a move message every time you acctually move. And then that message is braudcasted to everyone that can see that player.

So, the CMSG_MOVE (cmsg = client message, smsg = server message) takes the x and y coordinate to move to parameters. So you receive 4 bytes for the message and than put it through a switch statement to know how much to receive for the parameters. The switch case CMSG_MOVE goes through and you know to receive the x and y coordinates.

At least thats what I do...
