OK so I am making a adventure map and I am going to have 2 teams against each other. The game is basically a team death-match. I don't know how to have it so that there is 2 teams and if you kill someone you get a point and if you die you lose a point. I have seen that it is a command and that there is a scoreboard on the right side of the screen. And how do you assign people to a team? Do they have to be in a room and then have a command block which sets their team? And if so is there a points detector so that when a team gets for example 50 points then they win? Please help i'm confused
