Hello, I have been trying to code a /duel (player name) /duel accept plugin to work ALLL day. But I cannot seem to make it work. What I need: Commands: /duel (player name) /duel accept Mechanics: What will happen is when a player does /duel accept. It will add them to a hashmap making them only able to attack eatch other and no one will be able to attack them. I need 10 different set able 1v1 boxes and if they are full it needs to say: "Full! Sorry!" I really need this because I own a successful kitpvp server I code for but I cant get this to work. Thanks if you can. Other plugins: I have searched, searched, and searched. But I cant find a simple plugin that does this. Thanks for this if you can and if you can help me code it it would help too.
