How can i make npcs queue?

The following is an example for the Citizens plugin, but the method should be similar for other npc plugins too.

1. To make the queue via an npc, the process is pretty easy. First, you need to select your npc by doing Select the NPC: Face the NPC and run the following command to select it: /npc select

2. Add the Duels Command: Once you've selected the NPC, you can assign the duels play command. This example will allow the NPC to queue the player for an unranked 1v1 duel in classic mode: /npc command add duels play unranked solo classic

This will automatically queue the player for an unranked 1v1 match with classic mode when they interact with the NPC.
