 Client requesting a list of content info based on an external 'unique' id; GRF ID + MD5 checksum for NewGRFS, shortname and xor-ed MD5 checsums for base graphics and AIs.
 DECLARE_CONTENT_RECEIVE_COMMAND (PACKET_CONTENT_SERVER_INFO)
 Server sending list of content info: byte type (invalid ID == does not exist) uint32 id uint32 file_size string name (max 32 characters) string version (max 16 characters) uint32 unique id uint8 md5sum (16 bytes) uint8 dependency count uint32 unique id of dependency (dependency count times) uint8 tag count string tag (max 32 characters for tag count times).

Member Function Documentation

NetworkContentSocketHandler::DECLARE_CONTENT_RECEIVE_COMMAND ( PACKET_CONTENT_CLIENT_INFO_EXTID_MD5   )  [protected]

Client requesting a list of content info based on an external 'unique' id; GRF ID + MD5 checksum for NewGRFS, shortname and xor-ed MD5 checsums for base graphics and AIs.

Scenarios and AI libraries are not supported uint8 count of requests for each request: uint8 type unique id (uint32) md5 (16 bytes)

NetworkContentSocketHandler::DECLARE_CONTENT_RECEIVE_COMMAND ( PACKET_CONTENT_CLIENT_INFO_EXTID   )  [protected]

Client requesting a list of content info based on an external 'unique' id; GRF ID for NewGRFS, shortname and for base graphics and AIs.

Scenarios and AI libraries are not supported uint8 count of requests for each request: uint8 type unique id (uint32)

bool NetworkContentSocketHandler::HandlePacket ( Packet p  )  [protected]

Handle the given packet, i.e.

Handle an incoming packets by sending it to the correct function.

pass it to the right parser receive command.

Parameters:
p the packet to handle
Returns:
true if we should immediatelly handle further packets, false otherwise
Parameters:
p the received packet
