Authentication
==============
.. currentmodule:: authentication
.. _Yggdrasil: http://wiki.vg/Authentication
.. _LoginResponse: http://wiki.vg/Authentication#Authenticate
The authentication module contains functions and classes to facilitate
interfacing with Mojang's Yggdrasil_ service.
Logging In
~~~~~~~~~~~~~~~~~~~~
The most common use for this module in the context of a client will be to
log in to a Minecraft account. The convenience method
.. autofunction:: login_to_minecraft
should be used which will return a LoginResponse object. See LoginResponse_ for more details on the returned attributes
.. autoclass:: LoginResponse
:members:
or raise a YggdrasilError on failure, for example if an incorrect username/password
is provided or the web request failed
.. autoexception:: YggdrasilError
:members:
Arbitary Requests
~~~~~~~~~~~~~~~~~~~~
You may make any arbitary request to the Yggdrasil service with
.. automodule:: authentication
:members: BASE_URL
.. autofunction:: make_request
.. autoclass:: Response
:members:
---------------
Example Usage
---------------
An example of making an arbitary request can be seen here::
url = "https://sessionserver.mojang.com/session/minecraft/join"
server_id = encryption.generate_verification_hash(packet.server_id, secret, packet.public_key)
response = authentication.make_request(url, {'accessToken': self.connection.login_response.access_token,
'selectedProfile': self.connection.login_response.profile_id,
'serverId': server_id})

Connecting to Servers
======================
.. currentmodule:: network.connection
Your primary dealings when connecting to a server will deal with the Connection class
.. automodule:: network.connection
:members:
Dealing wih 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:
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

You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Welcome to pyCraft's documentation!
===================================
``pyCraft`` is a python project to handle networking
between a Minecraft server as a client.
The authentication package contains utilities to manage communicating
with Mojang's in order to log in with a minecraft account, edit profiles etc
The Connection class under the networking package handles
connecting to a server, sending packets, listening for packets etc
