Hey all. I am working on a team based PvP plugin that has 2 teams which each have their own permission group using GroupManager. What I am trying to figure out is how I can make it so one team can kill the other team but not members of the same team. Think of it as Red vs Blue for simplicity, red can kill blue and blue can kill red, but red can't kill red and blue can't kill blue. I'd like to make it simple and just be able to put like pvp.red and pvp.blue for each group. Those would be permissions that make a team part of an actual side/team. Any help would be greatly appreciated, thanks.
