When you look at your packets logs, you will very often see a "0x02 packet" from client.
This packet can have 2 "meanings".
The first is , that it acknolegde a receiving from a server packet.
The second is a "ping" answer.
And depending on the flag that is set , it can request the SimTime, so you get the Answer
"82" + 4 bytes Sim Timestamp.
At the beginning i had problems to understand how they work, cause if you are in the world and dont moove they are permanent send.
So now i understand the technique of it a little bit :
if you dont moove or turn your character, the server updates all objects in your near permanent (for a example: other players, mobs etc.).
If there is no other object in the near, the server does this update not so often (only every 1 or 2 seconds).
If you now would moove your character, the client send that the client wants to moove from position X to position Y.
And Server says something like "okay lets him do".
Another interesting thing is that the server syncronize with the client the players position, means when a client moove and the position isnt right, the server corrects the client position .
However, if an object change or the player moove the server updates all objects / add objects that are in your range .
