How to make a Team Generator?

its really basic, once you have your random player, you can get the others.

players = game.Players:GetChildren()  -- gets current players
randomp = players[math.random(#players)]  -- picks random player
print(randomp.Name .. " is it") -- tells us who the random player is
--stuff for it player or random
for i,v in pairs(players)  do -- iterate the player table
    if v.Name ~= randomp.Name then -- whoever isn't 'it', will tell us who isn't
        print(v.Name .. " is not it") -- tells us who
            --stuff if not it
    end
end
