Functions

func ChangeLoginServer

func ChangeLoginServer(w *net.Message) error

ChangeLoginServer sends network message with ID 0x28, of uncertain functionality.

func CharacterList

func CharacterList(w *net.Message, chars []CharacterListEntry, premiumDays uint16) error

CharacterList sends the network message containing the passed characters on the character list, and tells the user they have premiumDays left.

func Error

func Error(w *net.Message, errorText string) error

Error writes a login error network message to the passed net.Message.

Passed error text will be included.

func FYI

func FYI(w *net.Message, fyiText string) error

FYI writes an FYI network message to the passed net.Messsage.

Passed FYI text will be included.

func MOTD

func MOTD(w *net.Message, motdText string) error

MOTD writes the message-of-the-day network message to the passed net.Message.

Passed motdText will be included.

The motdText should begin with ascii-encoded decimal number identifying the sequence number of the MOTD, then it should be followed by a newline set of characters (ascii 13+10, \r\n). The number is used by the client to avoid bothering the user with the same message that was already seen.

Types

type CharacterListEntry struct {
	CharacterName, CharacterWorld string
	GameFrontend                  gonet.TCPAddr
}

CharacterListEntry represents a single character presented on the character list.

	// contains filtered or unexported fields
}

func NewServer

func NewServer(pk *rsa.PrivateKey) (*LoginServer, error)

NewServer creates a new LoginServer which can decrypt the initial login message using the passed RSA private key.

func (*LoginServer) Serve

func (c *LoginServer) Serve(conn net.Conn, initialMessage *tnet.Message) error
