Connecting to Servers
|
|
======================
|
|
|
|
.. module:: minecraft.networking.connection
|
|
|
|
Your primary dealings when connecting to a server will be with the Connection class
|
|
|
|
.. autoclass:: Connection
|
|

Writing Packets
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The packet class uses a lot of magic to work, here is how to use them.
|
|
Look up the particular packet you need to deal with, for this example
|
|
let's go with the ``serverbound.play.KeepAlivePacket``
|
|
|
|
.. autoclass:: minecraft.networking.packets.serverbound.play.KeepAlivePacket
|
|
:undoc-members:
|
|
:inherited-members:
|
|
:exclude-members: read, write, context, get_definition, get_id, id, packet_name, set_values
|
|
|
|
Pay close attention to the definition attribute, and how our class variable corresponds to
|
|
the name given from the definition::
|
|
|
|
from minecraft.networking.packets import serverbound
|
|
packet = serverbound.play.KeepAlivePacket()
|
|
packet.keep_alive_id = random.randint(0, 5000)
|
|
connection.write_packet(packet)
|
|
|
|
and just like that, the packet will be written out to the server.
|
|
|
|
It is possible to implement your own custom packets by subclassing
|
|
:class:`minecraft.networking.packets.Packet`. Read the docstrings and in
|
|
packets.py and follow the examples in its subpackages for more details on
|
|
how to do advanced tasks like having a packet that is compatible across
|
|
multiple protocol versions.
|
|
|
|
Listening for Certain Packets
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Let's look at how to listen for certain packets, the relevant method being
|
|
|
|
.. automethod:: Connection.register_packet_listener
|
|
|
|
An example of this can be found in the ``start.py`` headless client, it is recreated here::
|
|
|
|
connection = Connection(options.address, options.port, auth_token=auth_token)
|
|
connection.connect()
|
|
|
|
def print_chat(chat_packet):
|
|
print "Position: " + str(chat_packet.position)
|
|
print "Data: " + chat_packet.json_data
|
|
|
|
from minecraft.networking.packets.clientbound.play import ChatMessagePacket
|
|
connection.register_packet_listener(print_chat, ChatMessagePacket)
|
|
|
|
The field names ``position`` and ``json_data`` are inferred by again looking at the definition attribute as before
|
|
|
|
.. autoclass:: minecraft.networking.packets.clientbound.play.ChatMessagePacket
|
|
:undoc-members:
|
|
:inherited-members:
|
|
:exclude-members: read, write, context, get_definition, get_id, id, packet_name, set_values
