## Enumeration Type Documentation

enum DefaultMessageIDTypes

You should not edit the file MessageIdentifiers.h as it is a part of RakNet static library To define your own message id, define an enum following the code example that follows.

     enum {
       ID_MYPROJECT_MSG_1 = ID_USER_PACKET_ENUM,
       ID_MYPROJECT_MSG_2,
        ...
     };

Note:
  All these enumerations should be casted to (unsigned char) before writing them to RakNet::BitStream

Enumerator:

  ID_INTERNAL_PING | These types are never returned to the user. Ping from a connected system. Update timestamps (internal use only)
  ID_PING | Ping from an unconnected system. Reply but do not update timestamps. (internal use only).
  ID_PING_OPEN_CONNECTIONS | Ping from an unconnected system. Only reply if we have open connections. Do not update timestamps. (internal use only).
  ID_CONNECTED_PONG | Pong from a connected system. Update timestamps (internal use only).
  ID_CONNECTION_REQUEST | Asking for a new connection (internal use only).
  ID_SECURED_CONNECTION_RESPONSE | Connecting to a secured server/peer (internal use only).
  ID_SECURED_CONNECTION_CONFIRMATION | Connecting to a secured server/peer (internal use only).
  ID_RPC_MAPPING | Packet that tells us the packet contains an integer ID to name mapping for the remote system (internal use only).
  ID_DETECT_LOST_CONNECTIONS | A reliable packet to detect lost connections (internal use only).
  ID_OPEN_CONNECTION_REQUEST | Offline message so we know when to reset and start a new connection (internal use only).
  ID_OPEN_CONNECTION_REPLY | Offline message response so we know when to reset and start a new connection (internal use only).
  ID_RPC | Remote procedure call (internal use only).
  ID_RPC_REPLY | Remote procedure call reply, for RPCs that return data (internal use only).
  ID_OUT_OF_BAND_INTERNAL | RakPeer - Same as ID_ADVERTISE_SYSTEM, but intended for internal use rather than being passed to the user. Second byte indicates type. Used currently for NAT punchthrough for receiver port advertisement. See ID_NAT_ADVERTISE_RECIPIENT_PORT.
  ID_CONNECTION_REQUEST_ACCEPTED | RakPeer - In a client/server environment, our connection request to the server has been accepted.
  ID_CONNECTION_ATTEMPT_FAILED | RakPeer - Sent to the player when a connection request cannot be completed due to inability to connect.
  ID_ALREADY_CONNECTED | RakPeer - Sent a connect request to a system we are currently connected to.
  ID_NEW_INCOMING_CONNECTION | RakPeer - A remote system has successfully connected.
  ID_NO_FREE_INCOMING_CONNECTIONS | RakPeer - The system we attempted to connect to is not accepting new connections.
  ID_DISCONNECTION_NOTIFICATION | RakPeer - The system specified in Packet::systemAddress has disconnected from us. For the client, this would mean the server has shutdown.
  ID_CONNECTION_LOST | RakPeer - Reliable packets cannot be delivered to the system specified in Packet::systemAddress. The connection to that system has been closed.
  ID_RSA_PUBLIC_KEY_MISMATCH | RakPeer - We preset an RSA public key which does not match what the system we connected to is using.
  ID_CONNECTION_BANNED | RakPeer - We are banned from the system we attempted to connect to.
  ID_INVALID_PASSWORD | RakPeer - The remote system is using a password and has refused our connection because we did not set the correct password.
  ID_MODIFIED_PACKET | RakPeer - A packet has been tampered with in transit. The sender is contained in Packet::systemAddress.
  ID_TIMESTAMP | RakPeer - The four bytes following this byte represent an unsigned int which is automatically modified by the difference in system times between the sender and the recipient. Requires that you call SetOccasionalPing.
  ID_PONG | RakPeer - Pong from an unconnected system. First byte is ID_PONG, second sizeof(RakNetTime) bytes is the ping, following bytes is system specific enumeration data.
  ID_ADVERTISE_SYSTEM | RakPeer - Inform a remote system of our IP/Port, plus some offline data.
  ID_REMOTE_DISCONNECTION_NOTIFICATION | ConnectionGraph plugin - In a client/server environment, a client other than ourselves has disconnected gracefully. Packet::systemAddress is modified to reflect the systemAddress of this client.
  ID_REMOTE_CONNECTION_LOST | ConnectionGraph plugin - In a client/server environment, a client other than ourselves has been forcefully dropped. Packet::systemAddress is modified to reflect the systemAddress of this client.
  ID_REMOTE_NEW_INCOMING_CONNECTION | ConnectionGraph plugin - In a client/server environment, a client other than ourselves has connected. Packet::systemAddress is modified to reflect the systemAddress of the client that is not connected directly to us. The packet encoding is SystemAddress 1, ConnectionGraphGroupID 1, SystemAddress 2, ConnectionGraphGroupID 2.
  ID_FILE_LIST_TRANSFER_HEADER | FileListTransfer plugin - Setup data.
  ID_FILE_LIST_TRANSFER_FILE | FileListTransfer plugin - A file.
