Teleporter Keeps Teleporting All Players?? (PLS HELP)

I'm not completely sure if this is the problem, but I assume the script you posted is a LocalScript and is parented to your character.

The script you posted is supposed to run anything under Teleporter1.Touched:Connect(function(hit) when Teleporter1 is touched.

The problem is, the script is inside of every character in the game. If anything touches Teleporter1, and game.Players.LocalPlayer is true, the Touched event will fire for every character because every character has the LocalScript to do so.

In other words, it's not Teleporter1 that's going to teleport you, but it's your own character with the LocalScript.

Your Script:

local Teleporter1 = workspace.Teleporter1
local Teleporter2 = workspace.Teleporter2
local TeleporterTouched = false

Teleporter1.Touched:connect(function(hit)
if game.Players.LocalPlayer then
    local HumanoidRootPart = script.Parent:FindFirstChild("HumanoidRootPart")
    local Torso = script.Parent:FindFirstChild("Torso")

    if hit.Name == "HumanoidRootPart" or hit.Name == "Torso" or hit.Name == "Handle" then
        if TeleporterTouched == false then

            print(hit.Name.." Touched Teleporter1")

            TeleporterTouched = true
            print(TeleporterTouched)

            if HumanoidRootPart then

                print("HumanoidRootPart")
                HumanoidRootPart.CFrame = CFrame.new(15.381, 3, 0.12)  -- Change The Position To Teleporter2 Position

            end

            if Torso then

                print("Torso")
                Torso.CFrame = CFrame.new(15.381, 3, 0.12)  -- Change The Position To Teleporter2 Position

            end

            wait(3)

            TeleporterTouched = false
            print(TeleporterTouched)

        end 
    end
end
end)

To fix this, we make a script inside of Teleporter1, and make it teleport any character that touches it.

How do we do that? First, we put a Script (not a LocalScript) inside of Teleporter1. Why a Script instead of LocalScript? Because LocalScripts are only ran by a client. We want the server to make characters teleport, so we use a Script.

You've already written most of the script, so all we need to do is change some variables so it won't error when changed to a Script or when parented into Teleporter1 instead of a character.

-- Remember, this is parented inside of Teleporter1, and is a Script.

local Teleporter1 = workspace.Teleporter1 -- or script.Parent, since Teleporter1 is the parent of this script.
local Teleporter2 = workspace.Teleporter2
local TeleporterTouched = false

Teleporter1.Touched:Connect(function(hit) -- use :Connect() instead of :connect(), since it's deprecated.
    if hit.Parent:FindFirstChild("Humanoid") then -- if the parent of the part that touched the teleporter has a Humanoid inside of it, it's most likely a character.
	    local theCharacter = hit.Parent -- hit.Parent would be the character that touched the teleporter.
	    local HumanoidRootPart = theCharacter:FindFirstChild("HumanoidRootPart")
	    local Torso = theCharacter:FindFirstChild("Torso")
	        if TeleporterTouched == false then
	
	            print(theCharacter.Name.." Touched Teleporter1")
	
	            TeleporterTouched = true
	            print(TeleporterTouched)
	
	            if HumanoidRootPart then
	
	                print("HumanoidRootPart")
	                HumanoidRootPart.CFrame = CFrame.new(15.381, 3, 0.12)  -- Change The Position To Teleporter2 Position
	
	            end
	
	            if Torso then
	
	                print("Torso")
	                Torso.CFrame = CFrame.new(15.381, 3, 0.12)  -- Change The Position To Teleporter2 Position
	
	            end
	
	            wait(3)
	
	            TeleporterTouched = false
	            print(TeleporterTouched)
	
	        end
	end
end)
