<p>A Royalnet Command is a small script that is run whenever a specific message is sent to a Royalnet interface.</p>
<p>A Command code looks like this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">royalnet.commands</span> <span class="k">import</span> <span class="n">Command</span>

<span class="n">name</span> <span class="o">=</span> <span class="s2">"ping"</span>
<span class="n">description</span> <span class="o">=</span> <span class="s2">"Play ping-pong with the bot."</span>

<span class="k">await</span> <span class="n">data</span><span class="o">.</span><span class="n">reply</span><span class="p">(</span><span class="s2">"Pong!"</span><span class="p">)</span>

<div class="section" id="creating-a-new-command">
<h2>Creating a new Command<a class="headerlink" href="#creating-a-new-command" title="Permalink to this headline">¶</a></h2>
<p>First, think of a <code class="docutils literal notranslate"><span class="pre">name</span></code> for your command.
It’s the name your command will be called with: for example, the “spaghetti” command will be called by typing <strong>/spaghetti</strong> in chat.
Try to keep the name as short as possible, while staying specific enough so no other command will have the same name.</p>
<p>Next, create a new Python file with the <code class="docutils literal notranslate"><span class="pre">name</span></code> you have thought of.
The previously mentioned “spaghetti” command should have a file called <code class="docutils literal notranslate"><span class="pre">spaghetti.py</span></code>.</p>
<p>Then, in the first row of the file, import the <a class="reference internal" href="apireference.html#royalnet.commands.Command" title="royalnet.commands.Command"><code class="xref py py-class docutils literal notranslate"><span class="pre">Command</span></code></a> class from <code class="xref py py-mod docutils literal notranslate"><span class="pre">royalnet</span></code>, and create a new class inheriting from it:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">royalnet.commands</span> <span class="k">import</span> <span class="n">Command</span>
<span class="k">class</span> <span class="nc">SpaghettiCommand</span><span class="p">(</span><span class="n">Command</span><span class="p">):</span>
<span class="o">...</span>
</pre></div>
</div>
<p>Inside the class, override the attributes <code class="docutils literal notranslate"><span class="pre">name</span></code> and <code class="docutils literal notranslate"><span class="pre">description</span></code> with respectively the <strong>name of the command</strong> and a <strong>small description of what the command will do</strong>:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">royalnet.commands</span> <span class="k">import</span> <span class="n">Command</span>
<span class="k">class</span> <span class="nc">SpaghettiCommand</span><span class="p">(</span><span class="n">Command</span><span class="p">):</span>
<span class="n">name</span> <span class="o">=</span> <span class="s2">"spaghetti"</span>
<span class="n">description</span> <span class="o">=</span> <span class="s2">"Send a spaghetti emoji in the chat."</span>
</pre></div>
</div>
<p>Now override the <a class="reference internal" href="apireference.html#royalnet.commands.Command.run" title="royalnet.commands.Command.run"><code class="xref py py-meth docutils literal notranslate"><span class="pre">Command.run()</span></code></a> method, adding the code you want the bot to run when the command is called.</p>
<p>To send a message in the chat the command was called in, you can use the <a class="reference internal" href="apireference.html#royalnet.commands.CommandData.reply" title="royalnet.commands.CommandData.reply"><code class="xref py py-meth docutils literal notranslate"><span class="pre">CommandData.reply()</span></code></a> method:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">royalnet.commands</span> <span class="k">import</span> <span class="n">Command</span>
<span class="k">class</span> <span class="nc">SpaghettiCommand</span><span class="p">(</span><span class="n">Command</span><span class="p">):</span>
<span class="n">name</span> <span class="o">=</span> <span class="s2">"spaghetti"</span>
<span class="n">description</span> <span class="o">=</span> <span class="s2">"Send a spaghetti emoji in the chat."</span>
<span class="k">async</span> <span class="k">def</span> <span class="nf">run</span><span class="p">(</span><span class="bp">self</span><span class="p">,</span> <span class="n">args</span><span class="p">,</span> <span class="n">data</span><span class="p">):</span>
<span class="n">data</span><span class="o">.</span><span class="n">reply</span><span class="p">(</span><span class="s2">"🍝"</span><span class="p">)</span>
</pre></div>
</div>
<p>And it’s done! The command is now ready to be used in a bot!</p>
