Connecting to Servers
|
|
======================
|
|
|
|
.. module:: network.connection
|
|
|
|
Your primary dealings when connecting to a server will deal with the Connection class
|
|
|
|
.. autoclass:: network.connection.Connection
|
|
:members:
|
|
|
|
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 my example let's go with the ``KeepAlivePacket``
|
|
|
|
.. autoclass:: network.packets.KeepAlivePacket
|
|
:undoc-members:
|
|
:inherited-members:
|
|
:exclude-members: read, write
|
|
|
|
Pay close attention to the definition attribute, we're gonna be using that to assign values within the packet::
|
|
|
|
packet = 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
|
|
|
|
Listening for Certain Packets
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Let's look at how to listen for certain packets, the relevant method being
|
|
|
|
.. automethod:: network.connection.Connection.register_packet_listener
|
|
|
|
An example of this can be found in the ``start.py`` headless client, it is recreated here::
|
|
|
|
connection = Connection(address, port, login_response)
|
|
connection.connect()
|
|
|
|
def print_chat(chat_packet):
|
|
print "Position: " + str(chat_packet.position)
|
|
print "Data: " + chat_packet.json_data
|
|
|
|
from network.packets 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:: network.packets.ChatMessagePacket
|
|

|
|
:inherited-members:

:exclude-members: read, write |
