Making a see through wall script?!

I have the script just need something that makes me see through walls any help?

If you want to make a part semi transparent during a function, try this:

game.Players.PlayerAdded:connect(function(player)
           if player.Name == Robloxian_Hero1234 then
                game.Workspace.Partnamehere.Transperency = 1 -- How invisible part is
           end
      end
end
