The Ultimate Sims 4 UI Cheats Extension Guide (2025 Update): 10 Hidden Features You Need To Know

Contents

The Sims 4 UI Cheats Extension mod has cemented its place as the single most essential tool for any player who uses cheats, completely transforming the way you interact with your game. Instead of typing lengthy commands into the console, this mod allows you to manipulate nearly every aspect of your Sim’s life with a simple click or right-click directly on the User Interface (UI). This guide, updated for the latest major game patches as of December 2025, provides the definitive breakdown of how to download, install, and master every hidden feature of this powerful mod.

As of late December 2025, The Sims 4 has undergone several significant updates, including the major Patch 1.120 released on December 2nd. This patch, like all others, temporarily broke many popular script mods, including the UI Cheats Extension. It is absolutely critical that you download the most current, updated version (often v1.49 or v1.50) from the official creator to ensure compatibility and avoid frustrating script errors or UI glitches in your game.

The Definitive List of UI Cheats Extension Commands (Right-Click Master List)

The true power of the UI Cheats Extension lies in its intuitive, clickable nature. Instead of memorizing codes, you simply right-click on the element you want to change. Here is a comprehensive list of the most important and time-saving interactions, often referred to as "Relationship Cheats," "Skill Cheats," and "Career Cheats."

1. Money and Funds Cheats

  • Change Household Funds: Right-click on the Household Funds (Simoleons) counter in the bottom left corner of the screen. A pop-up box will appear, allowing you to type in any exact numerical value for your Simoleons.

2. Needs and Moodlets Cheats

  • Fill Needs: Click on any individual Need Bar (Hunger, Bladder, Fun, etc.) to instantly fill it to 100%.
  • Adjust Needs: Right-click on any individual Need Bar to set the exact value for that need, from completely empty to completely full.
  • Remove Moodlets: Right-click on any Moodlet (the small icons that indicate a Sim's current emotion, like "Tense" or "Happy") to instantly remove it. This is perfect for instantly eliminating negative Moodlets or Fears.
  • Change Emotions: Right-click on the Sim's portrait to access a menu of available emotions and instantly change your Sim's current emotional state.

  • Change Sim Age: Right-click on the Sim’s age bar in the Simology Panel to instantly age them up or down within their current life stage.

Troubleshooting: How to Fix UI Cheats Extension Not Working After a Patch

The most common issue players face is the mod suddenly "breaking" after a major game patch, such as the December 2025 update. This usually manifests as missing UI elements, graphical glitches, or the cheats simply not working. Follow these steps to resolve nearly all compatibility and installation issues.

Step 1: Verify Game Settings

The UI Cheats Extension is a script mod, which requires specific settings to be enabled in your game. Always check this first, as a game update can sometimes reset your options.

  • Go to Game Options > Other.
  • Ensure both Enable Custom Content and Mods and Script Mods Allowed are checked.
  • Apply the changes and restart the game.

Step 2: Delete the Cache File

The `localthumbcache.package` file stores outdated data from old mods and can cause conflicts when a mod is updated. Deleting it forces the game to generate a fresh file.

  • Exit The Sims 4 completely.
  • Navigate to your main Sims 4 folder (typically in Documents/Electronic Arts/The Sims 4).
  • Find and delete the file named localthumbcache.package.

Step 3: Check Installation Path (Crucial for Script Mods)

Script mods like UI Cheats Extension must be placed directly in the main Mods folder and should not be nested too deeply in sub-folders.

  • Go to your Mods folder (Documents/Electronic Arts/The Sims 4/Mods).
  • The downloaded file (which contains both the .package and .ts4script files) should be placed directly inside the Mods folder or only one folder deep.
  • Do not place the mod's files inside a sub-folder that is more than one level deep, as the game will not read the script file.

Step 4: Download the Latest Version (The Permanent Fix)

If the mod breaks, it is almost always because your version is outdated. The official creator, Weerbesu, is quick to update the mod after a patch, but you must manually download and replace the old files.

  • Delete the old UI Cheats Extension files from your Mods folder.
  • Visit Weerbesu's official Patreon page and download the newest version (e.g., v1.50 for the post-December 2025 patch).
  • Place the new files into your Mods folder and restart the game. This should resolve all script errors and restore full functionality.
