If you've been returning to life sims of years past, you'll want to brush up on all the Sims 3 cheats at your disposal. Personally, I just needed to remind myself the syntax for the move objects cheat in this one so I could get down to building freely as usual, but you may be on the hunt for The Sims 3 money cheats, or trying to fix your Sims' dismal moods by "cheating needs." The prior game in the series doesn't have quite as stacked a list of cheats as in The Sims 4, so there's a lot less to memorize here, thank goodness.
Enabling cheats in The Sims 3 is very familiar, but one thing you'll want to be mindful of is that capitalization matters in a lot of these cheats. If a cheat isn't working for you, double check you haven't messed that part up. When in a pinch, you can also use "testingcheatsenabled true" and then just enter "help" to see a list of cheats. There are more than just cheat codes to know, though. Once you've enabled testing cheats, you can trigger other effects by using Shift+Click or Ctrl+Click on certain objects and Sims, as detailed below.
To enable cheats in The Sims 3, press Ctrl+Shift+C to open the cheat console. Enter the cheats below as written or by filling in relevant values and press Enter to activate them. Press Esc to close the cheat console without entering a cheat.
Many cheats won't return a confirmation message, so you'll have to pay attention to whether your household funds, Sim needs, or other values changed as expected. Some cheats, explained below, require that you first use "testingcheatsenabled true" so watch out for that.
hideHeadlineEffects true/false
This cheat hides plumbobs over Sims' heads, but does not remove thought bubbles, which is useful for taking screenshots.
resetSim [first name] [last name]
For example, "resetSim Mortimer Goth" cancels a Sim's current action and resets their position if stuck, but does not change their needs or mood.
Ctrl+Click to remove moodlets
After using "testingCheatsEnabled true" you can hold Ctrl then left-click on any moodlet in the interface to remove it from your Sim.
To cheat the "needs" meters in The Sims 3 first use "testingcheatsenabled true" and then Ctrl+Click and drag on your Sim's need bar to change its value. You can raise or lower any of your Sim's needs this way. As mentioned above, you can also Ctrl+Click on any moodlet to remove it from your Sim.
moveobjects on/off
The most common Build/Buy cheat allows you to place objects more freely, even if they're clipping into another object.
disableSnappingToSlotsOnAlt true/false
This is a long but handy cheat for cluttering a build. It stops objects from snapping into slots on surfaces like tables or counters while you are holding Alt. You might use this to place objects under a table, for instance.
buydebug true/false
Allows you to buy and place "debug objects" that are normally inaccessible such as animal spawners and small clutter items. You can find them categorized in the ? symbol that appears beneath the normal Buy Mode categories.
fullscreen true/false
Forces your game into windowed or fullscreen mode.
fps on/off
This adds an FPS counter to the top right of your window.
maptags on/off
In the zoomed out neighborhood view, this disables or enables the symbols showing what each lot is. Though this works when looking at your full neighborhood while playing a household, this does not work when in Edit Town mode.
discotags
In the zoomed out neighborhood view, this makes lot symbols flash different colors, just for fun.
Before using any of the cheats below, enter "testingcheatsenabled true" and hit Enter. Now you can hold Shift and click on various targets.
