Make a door that more than one team can walk through?

My idea.

Alright so I think I know what you can do as if I remember correctly and correct me if i'm wrong but you can add more than one value to a NameValue such as TeamColor so I'm taking a guess at this to see if this works..

What I did

All I really did was just add "Teal" into the value of TeamColor, now of course you'll have to change that to a color of what you have. If that doesn't work, try changing the or to an ,

Here you go, my tiny extra fix.

TeamColor = "Maroon" or "Teal" --the team color allowed though
Time = 2   -- time to keep door opened
AntiHack = 1 --This is the mode it will do to intruders who touch the door   0= mostly nothing if they sneak, 1= pushes em back and sits em ^_^, 2=Kills em on touch....
ColorDoor = false --whether it colors the door the team color you disignated
----------------------------------------code------------------------------------------------------------------------------
Color=BrickColor.new(TeamColor)
on=false
s=script.Parent
ss=script.Parent:clone()
s.BrickColor=Color
function Check(hit) if on then return end
if hit==nil then return end
local player=game.Players:FindFirstChild(hit.Parent.Name)
if player==nil then return end
on=true
    if player.TeamColor==Color then
    s.Transparency=0
    s.CanCollide=false
    wait(Time)
    s.Transparency=ss.Transparency
    s.CanCollide=true
    else
    local h=player.Character:FindFirstChild("Humanoid")
    local t=player.Character:FindFirstChild("Torso")
    if t==nil or h==nil then s.CanCollide=true s.Transparency=ss.Transparency on=false return end
    if AntiHack==1 then
    h.Sit=true
    t.Velocity=t.CFrame:inverse().lookVector*80
    elseif AntiHack==2 then
    h.Health=0
    elseif AntiHack==0 then
    else hit.Parent=nil
    end
    end
on=false
end

s.Touched:connect(Check)

Well, you can make it checking the name in a dictionary tables, like a whitelist:

local List = {
    ["Maroon"] = true;
    -- ...
}

Then you need to check if List[tostring(Player.TeamColor)] then on the Touch Event, if its true, then you can make your functional, if not, kill the player. Example:

--> Services
local Players = game:GetService("Players")

--> Variables
local Part = script.Parent
local Debounces = {} --> Make a Player Debounce, for the player not touch soo much times in like 1 second.
local List = {
    ["Maroon"] = true;
}

Part.Touched:Connect(function(Hit)
    local Humanoid = Hit.Parent:FindFirstChild("Humanoid") --> Try to find Humanoid
    local Player = Humanoid and Players:GetPlayerFromCharacter(Hit.Parent) --> If Humanoid exists get player, else nil.
    if  Player then --> Check if the player exists
        if List[Player.TeamColor] then
            if Debounces[Player.Name] then return end --> If find the player Debounce then return.
            Debounces[Player.Name] = true --> Set debounce to true.
            --> Player allowed
            Part.Transparency = 0.5
            Part.CanCollide = false
            delay(1, function() --> After 1 second, close the door
                Part.Transparency = 0
                Part.CanCollide = true
                --> Here set Debounce to false
                Debounces[Player.Name] = false
            end)
        else
            --> Here, just do the kill.
            Humanoid.Parent:BreakJoints() --> Instant kill...
        end
    end
end)

Hope it helped!
