This week I am just doing sims 3 no exspansion packs. To open the cheat bar in sims 3 hit the keys CTRL SHIFT C at the same time. To add lifetime happiness, just open the cheat bar on the page where you click the check for your family and type in cheat number 4.
Motherlode: Gives your household 50,000 simeloens
Kaching: Gives your household 1,000 simeloens
Help: Will display a lot of cheats
Testingcheatsenabled true: You can shift+click many items to see what comes up.
Moveobjects on: No limit to where you can move objects (also moveobjects off will turn it off)
