local Player = game:GetService("Players").LocalPlayer local Character = Player.Character local Portal = game:GetService("Workspace").PortalOne.Portal

function Navigate() if (Portal.Position - Character.Torso.Position).Magnitude < 20 then Portal.Transparency = 0 Portal.CanCollide = true Portal.PortalScript.Disabled = false end end

while true do Navigate() wait(0.1) end
