			local position = mouse.Hit
			local target = position.p
			script.Parent.BuildSound:Play()
			if firstTime == true then
				firstTime = false
				script.Parent.Teleporters:MoveTo(Vector3.new(math.random(-200,200), 1000, math.random(-200,200)))
				script.Parent.Teleporters.Parent = game.Players.LocalPlayer.Character
			end
			if currentColor == 1 then
				game.Players.LocalPlayer.Character.Teleporters.Red.Position = target
				currentColor = 2
				script.Parent.Open:Play()
			elseif currentColor == 2 then
				game.Players.LocalPlayer.Character.Teleporters.Blue.Position = target
				currentColor = 1
				script.Parent.Open:Play()
