How to Have Your Sims Never Have Their Needs Go Down on the Sims 3.

Do you hate having to sleep, eat, or use the bathroom in The Sims 3 when you could be building skills or exploring tombs? This cheat will give your whole household bladders of steel and bottomless energy.

Steps

1. 

   Enter the household you want to freeze the motives of.

2. 

   Open the cheat console. Hold down Ctrl+⇧ Shift+C. A small bar should appear at the top of the game window.
   • Windows Vista users may have to hold down the Windows button along with the other three.

3. 

   Enable testingcheats. Type testingcheatsenabled true and hit Enter.

4. 

   Hold down ⇧ Shift and click on the mailbox in front of your house.

5. 

   Select Make All Happy. This will fill all your Sims' needs bars. It only affects the Sims you control, not any NPCs or visitors in your household.
   • You can also click and drag the needs bars up and down with your mouse. This will stop working after you make needs static.

6. 

   Select Make Needs Static. Shift-click the mailbox a second time and select Make Needs Static. Your Sims' needs will not change as long as this is enabled.
   • To make Sims' needs behave normally again, shift-click the mailbox and press Make Needs Dynamic.
