Packet

Details

This will not explain the basics of networking, but more specifically what an SOEPacket is.
A "packet" is the most basic form of data that can be sent from either the client or server.

There is a specific set of packets for:

• Connecting
  • 1. Session Request
  • 2. Session Response
• Sending multiple packets
  • 3. Multi
• Disconnecting
  • 5. Disconnect
• Pinging
  • 6. Keep Alive
• Sending messages
  • 9. Reliable Data
  • 0D. Fragmented Reliable Data
  • 15. Reliable Data Acknowledge

A full listing can be found here.

Name	Type	Byte-Order	Description
OpCode	uint16	Net	The type of packet. (The operation that should be carried out)
Packet Header	N/A	N/A	Determines whether the packet args are compressed, or encrypted.
Packet Args	N/A	N/A	The data for this packet.
CRC Checksum	byte[]	Net	The CRC of the entire contents of the packet. More info here.

Note: The packet header and CRC checksum only appear in packets after the initial connection handshake.
Implementation: SOEPacket

Handling a Packet

If you come across a message that is not handled please contribute to this repository and add it into the SOEProtocol handlers found here.

All packet types should be handled.

Writing a Packet

You can write packets through an SOEWriter instance that has been initialized to write packets.

SOEWriter writer = new SOEWriter(0x02, false);

Calling GetFinalSOEMessage on a writer that is set-up to write packets will return null in any case.
