Short example from the past and now
Past example was ASCII
TimeStamp PacketID 1 1 1 1 1 1 -1
Right now
TimeStamp
PacketID
RetCode
Parametar ( like 1 1 1 -1 )
A Small Hint
if you got some old client from prev changment for packet system all you need to do is just to replace your ASCII Packet corresponding uint8
from now you can reverse each class structures and doing your private server with latest client ofcourse would take time.
All Packet Structures Size is 24576 so class wouldnt be bigger then this size.
I Used for some years for clb. i just abbandoned the project :mofo:
