Fulfill Needs
Press "Ctrl," "Shift" and "C" simultaneously during the game to open up the console window, and then type "Maxmotives" to fill the Motives bars of your sims. Next, enter "MotiveDecay On" to prevent the motives from ever declining. You now have a situation where your sims will never want anything, such as feeding or needing to use the bathroom. If you would prefer to adjust your sims motives a more manual way, open the console window using the method previously stated and type "boolProp testingCheatsEnabled." You can now simply treat the Motives and Skills meters as slider bars, clicking and dragging them to a desired point.
Become a Witch
Enter "boolprop testingcheatsenabled true" into the console window and click the mailbox while holding "Shift." Select "NPC" and choose either the good or bad "Grad High Witch." Click a sim while holding "Shift" once the witch arrives and choose "Spawn" followed by "Tombstone of L and D." Click the tombstone and select the option "'Make me friendly to everyone here," and then socialize with the witch by talking to her. If you selected the good witch, click her and select "Teach the way of the light." For the bad witch, click her and select "Teach the path of darkness." Your sim will transform into a witch.
Five-Hour Pregnancy
Enter the console window if you have a pregnant sim and input the cheat "Boolprop testingcheatsenabled true." Click a sim while holding shift and choose "Spawn," and then "Tombstone of L and D." Click the tombstone and choose the option "Speed up my pregnancy." Select the sim who is pregnant from the list of names, and she will give birth in five hours at the most.
Maximum Skills
Select the bookshelf when your sim is in a good mood and choose to study a physiology book. When your sim finishes studying, immediately go outside and select "Jump Rope." Check your Body Skill, and you will see it is at its highest possible level. Now study from another book, and the corresponding skill will change to its optimum level too. Do this with every book to fill all of the Skills bars.
