How to make teaming system more randomized?

Help and Feedback Scripting Support
1

I have a simple method that evenly splits players into 2 teams, but it teams the same players together every round. Is there a way to re script this and make it more random?

(c is the player, and this current code uses a for a,c in ipairs(game.Players:GetPlayers()) do)

-teams have to be even
-teams have to be randomized

if team == "red" then
	c.FTEAM.Value = "Red"
team = "blue"
	else
	c.FTEAM.Value = "Blue"
team = "red"
end
2 
local teamColors = {"Blue","Red"}
for a, c in pairs(game.Players:GetChildren()) do
	c.FTEAM.Value = teamColors[math.random(1,#teamColors)] -- Choose a random value from the teamColor list
end

You can also implement math.randomseed() to help vary the randomness from server to server, however ‘true random number generation’ is its own rabbit hole

will this make the teams even?

No; but this will (assuming you have an even number of players):

local players = game.Players:GetPlayers()
for i = 1,  #players do
	players[i].FTEAM.Value = "Red"
	if i%2 == 0 then 
		players[i].FTeam.Value = "Blue"
	end
end

But then there’s the issue of them being on the same teams every round.

nvm that was the same thing you had

Tested this a few times, and one time there were 3 people on 1 team (4 player server)

local function assignTeams(playersPerTeam)
	local players = game.Players:GetPlayers()
	local redTeam, blueTeam = {}, {}
	math.randomseed(tick())
	
	for i = #players, 2, -1 do
		local j = math.random(i)
		players[i], players[j] = players[j], players[i]
	end

	local currentTeam = redTeam
	for i, player in ipairs(players) do
		if #currentTeam < playersPerTeam then
			table.insert(currentTeam, player)
			player.FTEAM.Value = "Red"
		else
			if currentTeam == redTeam then currentTeam = blueTeam
			end table.insert(currentTeam, player)
			player.FTEAM.Value = "Blue"
		end
	end
end

assignTeams(3) --playersPerTeam
Mockup 
local function assignTeams(playersPerTeam)
	local players = {"Player1", "Player2", "Player3", "Player4", "Player5", "Player6", "Player7", "Player8"}
	local redTeam, blueTeam = {}, {}
	math.randomseed(tick())

	for i = #players, 2, -1 do
		local j = math.random(i)
		players[i], players[j] = players[j], players[i]
	end

	local currentTeam = redTeam 
	for i, player in ipairs(players) do
		if #currentTeam < playersPerTeam then
			table.insert(currentTeam, player)
		else
			if currentTeam == redTeam then currentTeam = blueTeam
			end	table.insert(currentTeam, player)
		end
	end

	print("Red Team:", table.concat(redTeam, ", "))
	print("Blue Team:", table.concat(blueTeam, ", "))
end


for i = 1, 4 do	assignTeams(4) --playersPerTeam, testing 4, 4 times
	print(" ") task.wait(3)
end

Not sure if you want a set number or everyone.

Oop – dunno how I missed this


Confirmed this shuffles players each time and equally divides into two teams

-- Tables
local plrTable = game.Players:GetPlayers()
local shuffledPlrs = {}

-- Shuffle Players
for i, v in pairs (plrTable) do
	local slot = math.random(1,#plrTable)
	while shuffledPlrs[slot] do
		slot = math.random(1,#plrTable)
	end
	shuffledPlrs[slot] = v
end

-- Equally divide teams from shuffled table
local last = "Red"
for i, v in ipairs(shuffledPlayers) do
	if last == "Red" then
		last = "Blue"
	else
		last = "Red"
	end
	v.FTEAM.Value = last
end

Wish i could mark both as a solution, but looks good, thanks!
