<h1>Peer/server discovery</h1>
<p>
Peer discovery is the process of clients detecting what servers are available. Discovery requests can be made in two ways;
locally as a broadcast, which will send a signal to all peers on your subnet. Secondly you can contact an ip address directly
and query it if a server is running.
</p>
<p>Responding to discovery requests are done in the same way regardless of how the request is made.</p>
<p>Here's how to do on the client side; ie. the side which makes a request:</p>
<div class="cf">
<pre class="cl"><span class="cb1">// Enable DiscoveryResponse messages</span></pre>
<pre class="cl">config.EnableMessageType(<span class="cb2">NetIncomingMessageType</span>.DiscoveryResponse);</pre>
<pre class="cl">&nbsp;</pre>
<pre class="cl"><span class="cb1">// Emit a discovery signal</span></pre>
<pre class="cl">Client.DiscoverLocalPeers(14242);</pre>
</div>
<p>This will send a discovery signal to your subnet; Here's how to receive the signal on the server side, and send a response back to the client:</p>
<div class="cf">
<pre class="cl"><span class="cb1">// Enable DiscoveryRequest messages</span></pre>
<pre class="cl">config.EnableMessageType(<span class="cb2">NetIncomingMessageType</span>.DiscoveryRequest);</pre>
<pre class="cl">&nbsp;</pre>
<pre class="cl"><span class="cb1">// Standard message reading loop</span></pre>
<pre class="cl"><span class="cb3">while</span> ((inc = Server.ReadMessage()) != <span class="cb1">null</span>)</pre>
<pre class="cl">{</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; <span class="cb3">switch</span> (inc.MessageType)</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; {</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.DiscoveryRequest:</pre>
<pre class="cl">&nbsp;</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb1">// Create a response and write some example data to it</span></pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb2">NetOutgoingMessage</span> response = Server.CreateMessage();</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; response.Write(<span class="cb4">&quot;My server name&quot;</span>);</pre>
<pre class="cl">&nbsp;</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb1">// Send the response to the sender of the request</span></pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Server.SendDiscoveryResponse(response, inc.SenderEndpoint);</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">break</span>;</pre>
</div>
<p>When the response then reaches the client, you can read the data you wrote on the server:</p>
<div class="cf">
<pre class="cl"><span class="cb1">// Standard message reading loop</span></pre>
<pre class="cl"><span class="cb3">while</span> ((inc = Client.ReadMessage()) != <span class="cb1">null</span>)</pre>
<pre class="cl">{</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; <span class="cb3">switch</span> (inc.MessageType)</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; {</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">case</span> <span class="cb2">NetIncomingMessageType</span>.DiscoveryResponse:</pre>
<pre class="cl">&nbsp;</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb2">Console</span>.WriteLine(<span class="cb4">&quot;Found server at &quot;</span> + inc.SenderEndpoint + <span class="cb4">&quot; name: &quot;</span> + inc.ReadString());</pre>
<pre class="cl">&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; <span class="cb3">break</span>;</pre>
</div>
