How do you make a team only door that has something to do with the team name?

I have no idea how to script, so can you help me?

Seems you need a Touched event.

local Door = workspace.Door -- define the door
local debounce = false -- make sure to have a debounce

Players = game:GetService('Players') - we'll be needing this service



Door.Touched:Connect(function(otherPart)
	local Player = Players:GetPlayerFromCharacter(otherpart.Parent)
	if Player then
		if Player.Team == game.Teams['TeamNameHere'] and debounce == false then -- check team and debounce
			debounce = true
			Door.Transparency =.5
			Door.CanCollide = false
			wait(.5) -- how long before the door goes back to normal
			Door.Transparency = 0
			Door.CanCollide = true
			debounce  = false
		end
	end
end)

Make sure to properly define the door to make sure this works.
