+
+If you wish to receive a specific event packet, you will need to subscribe to the event. Once subscribed you can register a packet handler as normal (see example above).

+public class Example {

+        HypixelModAPI.getInstance().subscribeToEventPacket(ClientboundLocationPacket.class);
+    }
