Basically. When 2 players duel they get the parameters added to their name (player1, player2) but we have multiple players dueling in the same arena and they cant see each other or anything but the duels can clash if they come into each other. For example player1 is dueling player2 but then another player1 and player2 join which is completely 2 other random people and if that other player1 hit the other player1 it would allow it, same for player2 and player2+player1. The duels can clash basically. Also the potions clash so when you are dueling you can see the other player1+player2's potions and enderpearls if your in the same arena. Does anyone have a fix for this? Im like super tired right now and really confused with it. I've done java but rarely bukkit. I will list all the classes that you will need below.
