Setting a players team(In a localScript only)?

I've been working on a team changer GUI

I have it teleporting you to a specific spot.... but i would love it if it could just set your team, Instead of a spawning point. so i don't have to use a one way door I also have three teams

The Local script is located at:

StarterGui -> TeamMenu(ScreenGUI) ->LocalScript(TheLocalScript)

Inside the: "TeamMenu(ScreenGUI)" ChooseBlue(TextButton),ChooseRed(TextButton),ChooseGreen(TextButton),

here is what you need to know:

ChooseBlue  =  false
ChoosenGreen = false 
ChoosenRed = false
RedTeam = "Bright red"
BlueTeam = "Really blue"
GreentTeam = "Lime green"
BlueSpot = CFrame.new(-32, 4.6, 168)
RedSpot = CFrame.new(0, 0, 0)
GreenSpot = CFrame.new(0, 0, 0)
SetTeamBlue = false
SetTeamRed = false
SetTeamGreen = false

ChooseGreen.MouseButton1Down:connect(ChoosenGreen == true)
ChooseRed.MouseButton1Down:connect(ChoosenRed == true)
ChooseGreen.MouseButton1Down:connect(ChoosenBlue == true)

while ChoosenBlue == true do
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace
	wait()
	player.Character.Torso.Anchored = false
	wait()
	ChoosenBlue = false
	SetTeamBlue = true
end

while SetTeamBlue == true do
	--This is where you will become part of the Blue team
end

while ChoosenRed == true do
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace
	wait()
	player.Character.Torso.Anchored = false
	wait()
	ChoosenRed = false
	SetTeamRed = true
end

while SetTeamRed == true do
	--This is where you will become part of the red team
end

while ChoosenGreen == true do
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace
	wait()
	player.Character.Torso.Anchored = false
	wait()
	ChoosenGreen = false
	SetTeamGreen = true
end

while SetTeamGreen == true do
	--This is where you will become part of the Green team
end

I have no experience using teams with roblox and ask that when you awnser you explain what you did.

What you did is set variables to let the code jump around and mesh pieces of code together. I consolidated the into anonymous functions, but you could do with defined functions and call those functions from the connect methods. A question, did you mean "BlueSpot" or another color's var for "newplace"?

--You didn't need these variables.
RedTeam = "Bright red"
BlueTeam = "Really blue"
GreenTeam = "Lime green" --spelling error here. You had "GreentTeam".
BlueSpot = CFrame.new(-32, 4.6, 168)
RedSpot = CFrame.new(0, 0, 0)
GreenSpot = CFrame.new(0, 0, 0)
--You didn't need these variables either.

-- The below code is consolidated somewhat.


script.Parent.ChooseGreen.MouseButton1Down:connect(function() --You only need script.Parent if you didn't set a variable for it.
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace --What is newplace? It wasn't defined in the script you gave us. Did you mean "GreenSpot", the variable?
	wait()
	player.Character.Torso.Anchored = false
	wait()
	game.Players.LocalPlayer.TeamColor = BrickColor.new(GreenTeam) --TeamColor is a BrickColor value. I gave it the var you set earlier.
end)

ChooseRed.MouseButton1Down:connect(function()
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace --What is newplace?
	wait()
	player.Character.Torso.Anchored = false
	wait()
	game.Players.LocalPlayer.TeamColor = BrickColor.new(RedTeam)
end)

ChooseBlue.MouseButton1Down:connect(function() -- You had "ChooseGreen" twice.
	player.Character.Torso.Anchored = true
	wait()
	player.Character.torso.CFrame = newplace --What is newplace?
	wait()
	player.Character.Torso.Anchored = false
	wait()
	game.Players.LocalPlayer.TeamColor = BrickColor.new(BlueTeam)
end)

Here's the wiki documentation on teams and on an individual team.
