How do i add a whitelist for only players in this script? please help!

local Teleport = "tp2" --Put the name of the Part between the ""s. function Touch(hit) --Indicates that the Part has been Touched. if script.Parent.Locked == false and script.Parent.Parent:findFirstChild(Teleport).Locked == false then script.Parent.Locked = true script.Parent.Parent:findFirstChild(Teleport).Locked = true --Checks Debounce. local Pos = script.Parent.Parent:findFirstChild(Teleport) --Gets the Part to teleport to. hit.Parent:moveTo(Pos.Position) wait(1) script.Parent.Locked = false script.Parent.Parent:findFirstChild(Teleport).Locked = false end end --Takes you there and Ends the Function. script.Parent.Touched:connect(Touch) --Listens out for Touchers.

this is a teleporting script how do i add a whitelist to this script to make it only teleport players and not parts?

I rewrote your code.

local teleport = workspace:FindFirstChild("tp2") -- You may want to look elsewhere for this if it's not directly in "workspace".
local isPad = false -- Change this to "true" if your "tp2" is a pad, else leave it as is. 

script.Parent.Touched:Connect(function(hit)
	if hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid") then
		if isPad == true then
			hit.Parent.HumanoidRootPart.CFrame = CFrame.new(teleport.Position.X, (teleport.Position.Y + 6), teleport.Position.Z)
		else
			hit.Parent.HumanoidRootPart.CFrame = CFrame.new(teleport.Position)
		end
	end
end)

If this helps, you're welcome.
