How can 你 make your sim invisible?

Oh yeah I want to do it with no cheats but if there's cheats its alright. I dont want to use cheats because I have the first one not the 秒 one

So do 你 have the first sims of second??

Can 你 send me a link of that video? Because i play sims for like 8 years,and im very experienced with it.I must see the video to see what do 你 exactly want. :)
