|

<p>TODO: Channels are covered in <a class="reference internal" href="Communications.html"><span class="doc">Communications</span></a> right now.</p>
|
||||
<p>In a multiplayer game, players often need other means of in-game communication
|
||||
than moving to the same room and use <code class="docutils literal notranslate"><span class="pre">say</span></code> or <code class="docutils literal notranslate"><span class="pre">emote</span></code>.</p>
|
||||
<p><em>Channels</em> allows Evennia’s to act as a fancy chat program. When a player is
|
||||
connected to a channel, sending a message to it will automatically distribute
|
||||
it to every other subscriber.</p>
|
||||
<p>Channels can be used both for chats between <a class="reference internal" href="Accounts.html"><span class="doc">Accounts</span></a> and between
|
||||
<a class="reference internal" href="Objects.html"><span class="doc">Objects</span></a> (usually Characters). Chats could be both OOC
|
||||
(out-of-character) or IC (in-charcter) in nature. Some examples:</p>
|
||||
<ul class="simple">
|
||||
<li><p>A support channel for contacting staff (OOC)</p></li>
|
||||
<li><p>A general chat for discussing anything and foster community (OOC)</p></li>
|
||||
<li><p>Admin channel for private staff discussions (OOC)</p></li>
|
||||
<li><p>Private guild channels for planning and organization (IC/OOC depending on game)</p></li>
|
||||
<li><p>Cyberpunk-style retro chat rooms (IC)</p></li>
|
||||
<li><p>In-game radio channels (IC)</p></li>
|
||||
<li><p>Group telephathy (IC)</p></li>
|
||||
<li><p>Walkie talkies (IC)</p></li>

<p>If you temporarily don’t want to hear the channel for a while (without actually

<h3>Chat on channels<a class="headerlink" href="#chat-on-channels" title="Permalink to this headline">¶</a></h3>
|
||||
<p>To speak on a channel, do</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>channel public Hello world!
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>If the channel-name has spaces in it, you need to use a ‘<code class="docutils literal notranslate"><span class="pre">=</span></code>’:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>channel rest room = Hello world!
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Now, this is more to type than we’d like, so when you join a channel, the
|
||||
system automatically sets up an personal alias so you can do this instead:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">public</span> <span class="n">Hello</span> <span class="n">world</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<div class="admonition warning">
|
||||
<p class="admonition-title">Warning</p>
|
||||
<p>This shortcut will not work if the channel-name has spaces in it.
|
||||
So channels with long names should make sure to provide a one-word alias as
|
||||
well.</p>
|
||||
</div>
|
||||
<p>Any user can make up their own channel aliases:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">alias</span> <span class="n">public</span> <span class="o">=</span> <span class="n">foo</span><span class="p">;</span><span class="n">bar</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>You can now just do</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>foo Hello world!
|
||||
bar Hello again!
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>And even remove the default one if they don’t want to use it</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">unalias</span> <span class="n">public</span>
|
||||
<span class="n">public</span> <span class="n">Hello</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>But you can also use your alias with the <code class="docutils literal notranslate"><span class="pre">channel</span></code> command:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>channel foo Hello world!
|
||||
</pre></div>
|
||||
</div>
|
||||
<blockquote>
|
||||
<div><p>What happens when aliasing is that a <a class="reference internal" href="Nicks.html"><span class="doc">nick</span></a> is created that maps your
|
||||
alias + argument onto calling the <code class="docutils literal notranslate"><span class="pre">channel</span></code> command. So when you enter <code class="docutils literal notranslate"><span class="pre">foo</span> <span class="pre">hello</span></code>,
|
||||
what the server sees is actually <code class="docutils literal notranslate"><span class="pre">channel</span> <span class="pre">foo</span> <span class="pre">=</span> <span class="pre">hello</span></code>. The system is also
|
||||
clever enough to know that whenever you search for channels, your channel-nicks
|
||||
should also be considered so as to convert your input to an existing channel name.</p>
|
||||
</div></blockquote>
|
||||
<p>You can check if you missed channel conversations by viewing the channel’s
|
||||
scrollback with</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">history</span> <span class="n">public</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>This retrieves the last 20 lines of text (also from a time when you were
|
||||
offline). You can step further back by specifying how many lines back to start:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">history</span> <span class="n">public</span> <span class="o">=</span> <span class="mi">30</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>This again retrieve 20 lines, but starting 30 lines back (so you’ll get lines
|
||||
30-50 counting backwards).</p>

<h3>Channel administration<a class="headerlink" href="#channel-administration" title="Permalink to this headline">¶</a></h3>
|

<p>To create/destroy a new channel you can do</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">create</span> <span class="n">channelname</span><span class="p">;</span><span class="n">alias</span><span class="p">;</span><span class="n">alias</span> <span class="o">=</span> <span class="n">description</span>

<span class="n">channel</span><span class="o">/</span><span class="n">destroy</span> <span class="n">channelname</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Aliases are optional but can be good for obvious shortcuts everyone may want to
|
||||
use. The description is used in channel-listings. You will automatically join a
|
||||
channel you created and will be controlling it. You can also use <code class="docutils literal notranslate"><span class="pre">channel/desc</span></code> to
|
||||
change the description on a channel you wnn later.</p>
|
||||
<p>If you control a channel you can also kick people off it:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>channel/boot mychannel = annoyinguser123 : stop spamming!
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>The last part is an optional reason to send to the user before they are booted.
|
||||
You can give a comma-separated list of channels to kick the same user from all
|
||||
those channels at once. The user will be unsubbed from the channel and all
|
||||
their aliases will be wiped. But they can still rejoin if they like.</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">channel</span><span class="o">/</span><span class="n">ban</span> <span class="n">mychannel</span> <span class="o">=</span> <span class="n">annoyinguser123</span>

|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Banning adds the user to the channels blacklist. This means they will not be
|
||||
able to <em>rejoin</em> if you boot them. You will need to run <code class="docutils literal notranslate"><span class="pre">channel/boot</span></code> to
|
||||
actually kick them out.</p>
|
||||
<p>See the <a class="reference external" href="../api/evennia.commands.default.comms.CmdChannel.html">Channel command</a> api

docs (and in-game help) for more details.</p>

<p>When distributing a message, the channel will call a series of hooks on itself
|

and (more importantly) on each recipient. So you can customize things a lot by

just modifying hooks on your normal Object/Account typeclasses.</p>
|

<p>Internally, the message is sent with

<code class="docutils literal notranslate"><span class="pre">channel.msg(message,</span> <span class="pre">senders=sender,</span> <span class="pre">bypass_mute=False,</span> <span class="pre">**kwargs)</span></code>, where

<code class="docutils literal notranslate"><span class="pre">bypass_mute=True</span></code> means the message ignores muting (good for alerts or if you

delete the channel etc) and <code class="docutils literal notranslate"><span class="pre">**kwargs</span></code> are any extra info you may want to pass

to the hooks. The <code class="docutils literal notranslate"><span class="pre">senders</span></code> (it’s always only one in the default implementation

<h2>Channels in code<a class="headerlink" href="#channels-in-code" title="Permalink to this headline">¶</a></h2>
|
||||
<p>For most common changes, the default channel, the recipient hooks and possibly
|
||||
overriding the <code class="docutils literal notranslate"><span class="pre">channel</span></code> command will get you very far. But you can also tweak
|
||||
channels themselves.</p>
|
||||
<p>Channels are <a class="reference internal" href="Typeclasses.html"><span class="doc">Typeclassed</span></a> entities. This means they are
|
||||
persistent in the database, can have <a class="reference internal" href="Attributes.html"><span class="doc">attributes</span></a> and <a class="reference internal" href="Tags.html"><span class="doc">Tags</span></a>
|
||||
and can be easily extended.</p>
|
||||
<p>To change which channel typeclass Evennia uses for default commands, change
|
||||
<code class="docutils literal notranslate"><span class="pre">settings.BASE_CHANNEL_TYPECLASS</span></code>. The base command class is
|
||||
<a class="reference external" href="api:evennia.comms.comms.DefaultChannel"><code class="docutils literal notranslate"><span class="pre">evennia.comms.comms.DefaultChannel</span></code></a>.
|
||||
There is an empty child class in <code class="docutils literal notranslate"><span class="pre">mygame/typeclasses/channels.py</span></code>, same
|
||||
as for other typelass-bases.</p>
|
||||
<p>In code you create a new channel with <code class="docutils literal notranslate"><span class="pre">evennia.create_channel</span></code> or
|
||||
<code class="docutils literal notranslate"><span class="pre">Channel.create</span></code>:</p>

|

<ul class="simple">

sensible optimization since people offline people will not see the message anyway.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">log_file</span></code> - this is a string that determines the name of the channel log file. Default
|
||||
is <code class="docutils literal notranslate"><span class="pre">"channel_{channelname}.log"</span></code>. The log file will appear in <code class="docutils literal notranslate"><span class="pre">settings.LOG_DIR</span></code> (usually

<code class="docutils literal notranslate"><span class="pre">mygame/server/logs/</span></code>). You should usually not change this.</p></li>
|

<li><p><code class="docutils literal notranslate"><span class="pre">channel_prefix_string</span></code> - this property is a string to easily change how

the channel is prefixed. It takes the <code class="docutils literal notranslate"><span class="pre">channelname</span></code> format key. Default is <code class="docutils literal notranslate"><span class="pre">"[{channelname}]</span> <span class="pre">"</span></code>
|

<li><p><code class="docutils literal notranslate"><span class="pre">channel_msg_nick_pattern</span></code> - this is a regex pattern for performing the in-place nick

replacement (detect that <code class="docutils literal notranslate"><span class="pre">channelalias</span> <span class="pre"><msg</span></code> means that you want to send a message to a channel).

This pattern accepts an <code class="docutils literal notranslate"><span class="pre">{alias}</span></code> formatting marker. Don’t mess with this unless you really

the channel. The <code class="docutils literal notranslate"><span class="pre">**kwargs</span></code> are passed on into the other call hooks (also on the recipient).</p></li>
|

<li><p><code class="docutils literal notranslate"><span class="pre">at_post_channel_msg(message,</span> <span class="pre">**kwargs)</span></code> - by default this is used to store the message
|

to the log file.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">channel_prefix(message)</span></code> - this is called to allow the channel to prefix. This is called
|
||||
by the object/account when they build the message, so if wanting something else one can
|
||||
also just remove that call.</p></li>
|
||||
<li><p>every channel message. By default it just returns <code class="docutils literal notranslate"><span class="pre">channel_prefix_string</span></code>.</p></li>

what maps e.g. <code class="docutils literal notranslate"><span class="pre">alias</span> <span class="pre"><msg></span></code> to <code class="docutils literal notranslate"><span class="pre">channel</span> <span class="pre">channelname</span> <span class="pre">=</span> <span class="pre"><msg></span></code>.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">remove_user_channel_alias(user,</span> <span class="pre">alias,</span> <span class="pre">**kwargs)</span></code> - remove an alias. Note that this is
|

a class-method that will happily remove found channel-aliases from the user linked to <em>any</em>
|
||||
channel, not only from the channel the method is called on.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">pre_join_channel(subscriber)</span></code> - if this returns <code class="docutils literal notranslate"><span class="pre">False</span></code>, connection will be refused.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">post_join_channel(subscriber)</span></code> - by default this sets up a users’s channel-nicks/aliases.</p></li>
|

<li><p><code class="docutils literal notranslate"><span class="pre">pre_leave_channel(subscriber)</span></code> - if this returns <code class="docutils literal notranslate"><span class="pre">False</span></code>, the user is not allowed to leave.</p></li>
|
||||
<li><p><code class="docutils literal notranslate"><span class="pre">post_leave_channel(subscriber)</span></code> - this will clean up any channel aliases/nicks of the user.</p></li>
|

<li><p><code class="docutils literal notranslate"><span class="pre">delete</span></code> the standard typeclass-delete mechanism will also automatically un-subscribe all
