The Sims 4 relationship editor lets you change how your sims feel about each other without playing through months of in-game time

The fastest way to edit relationships in The Sims 4 is through the Relationship and Pregnancy Mod by roBurky, which you install like any other mod and then access through a menu in-game. Once installed, you click on a sim, select "Modify Relationships" from the pie menu, choose which other sim you want to adjust, and then set the relationship value to whatever you want — anywhere from -100 (enemies) to 100 (best friends or romantic partners). The mod also lets you change pregnancy status, which is useful if you want to skip the waiting period.

If you do not want to use mods, you can also use the Relationship Console cheat code, which is built into the base game. Type testingcheats on into the cheat console (opened with Ctrl+Shift+C on Windows or Cmd+Shift+C on Mac), then use commands like modifyrelationship [sim1 first name] [sim1 last name] [sim2 first name] [sim2 last name] [amount] [relationship type] to adjust relationships by a specific number of points. This method is slower than a mod because you have to type out each command, but it requires no read.

Key Takeaways

  • The Relationship and Pregnancy Mod is the easiest way to edit relationships because it gives you a menu instead of requiring you to type commands.
  • You can also use the built-in cheat console with testingcheats on, though this requires typing out each relationship change one at a time.
  • Relationship values range from -100 to 100, and different relationship types (friendship, romance, family) have separate tracks.
  • Mods and cheats do not break your save file or disable achievements, but they do disable the ability to earn trophies on console versions.

How the Relationship and Pregnancy Mod works

The Relationship and Pregnancy Mod by roBurky is hosted on ModTheSims and works with the current version of The Sims 4 on Windows and Mac. You read the .zip file, extract it to your Mods folder (usually Documents > Electronic Arts > The Sims 4 > Mods), and restart the game. Once it is installed, you click on any sim, scroll down in the pie menu, and select "Modify Relationships."

A window opens showing all the other sims in your household and neighborhood. You click on the sim you want to adjust the relationship with, and then you see three sliders: one for friendship, one for romance, and one for family. You can drag each slider to set the relationship value, or you can type a number directly into the box. The changes take effect when ready — you do not have to save or restart the game.

This mod also includes a "Modify Pregnancy" option in the same menu, which lets you set how far along a sim is in their pregnancy or remove pregnancy entirely. This is useful if you want to skip the three in-game days of pregnancy without using cheats.

Using the built-in cheat console instead

If you prefer not to install mods, The Sims 4 has a cheat console built into the base game. Open it by pressing Ctrl+Shift+C on Windows or Cmd+Shift+C on Mac, and a text box appears at the top of the screen. Type testingcheats on and press Enter to enable cheats for this play session.

Once cheats are on, you can type relationship commands. The basic format is modifyrelationship [first sim first name] [first sim last name] [second sim first name] [second sim last name] [number] [relationship type]. For example, modifyrelationship John Smith Jane Doe 50 friendship would add 50 friendship points between John and Jane. You can use negative numbers to decrease relationships, and you can use romance or family instead of friendship to adjust those tracks.

The cheat console method works on all platforms and does not require any downloads, but it is slower because you have to type out each command separately. If you have many sims or want to make large changes, the mod is more practical.

What relationship values mean in The Sims 4

Relationships in The Sims 4 are tracked on three separate scales: friendship, romance, and family. Each scale runs from -100 to 100, and where a sim falls on that scale determines how they interact with each other. A friendship value of 50 or higher means the sims are friends and will have positive interactions. A value of -50 or lower means they dislike each other and will have negative interactions. Values between -50 and 50 mean the sims are neutral toward each other.

Romance works the same way — a romance value of 50 or higher means the sims are attracted to each other and can pursue romantic interactions like kissing or moving in together. A value of -50 or lower means they actively dislike each other romantically. Family relationships work differently in that they are usually set automatically when you create a household, but you can still edit them if you want to change a sim's feelings toward their relatives.

When you use a mod or cheat to change a relationship, you are directly setting the value rather than earning it through gameplay. This means the sims will when ready treat each other according to that value, even if they have never met before.

Why you might want to edit relationships

The most common reason to edit relationships is to skip the time it takes to build them in-game. If you want two sims to fall in love and get married, it normally takes several in-game days of interactions to build up enough romance points. Editing the relationship lets you jump straight to the romantic interactions without the grind.

Another reason is to fix relationships that went wrong. If a sim insulted another sim and tanked the friendship, you can use the editor to restore it instead of playing through the apology interactions. Some players also use it to create specific family dynamics or friend groups that would be tedious to build through normal gameplay.

Some players use relationship editing for storytelling purposes — setting up a scenario where two sims are enemies, or where a sim has a one-sided crush on someone who does not like them back. The editor lets you create these situations without having to engineer them through gameplay.

Mods versus cheats: which method to choose

The Relationship and Pregnancy Mod is easier to use if you plan to edit relationships often, because you get a visual menu instead of typing commands. It is also faster if you need to make many changes at once. The downside is that you have to read and install it, and you need to keep it updated when The Sims 4 gets patched.

The cheat console method is better if you want to avoid mods entirely or if you only need to edit relationships occasionally. It requires no read and works on all platforms, including console versions of the game (though using cheats on console disables trophy earning). The downside is that it is slower and more error-prone if you mistype a sim's name.

Both methods are safe and do not break your save file or disable achievements on PC and Mac. On console versions, using cheats disables trophy earning for that save, but the game itself remains playable.

Common mistakes when editing relationships

The most common mistake is typing a sim's name wrong in the cheat console. If you type modifyrelationship John Smith Jane Doe 50 friendship but the sim's name is actually "Jon" without the "h", the cheat will not work and you will not get an error message — it will just do nothing. Check the exact spelling of both sims' names before you type the command.

Another mistake is forgetting to turn cheats on with testingcheats on before you try to use relationship commands. If you type a relationship command without enabling cheats first, nothing happens. You have to enable cheats every time you start a new play session — turning cheats on does not carry over when you close and reopen the game.

If you are using the mod, make sure you have extracted the .zip file to the Mods folder and not left it zipped. The game does not read zipped mod files, so the mod will not load. You can tell if the mod loaded correctly by clicking on a sim and checking whether "Modify Relationships" appears in the pie menu.

Frequently Asked Questions

Does editing relationships disable achievements?

No. On PC and Mac, using cheats or mods does not disable achievements. On console versions, using cheats disables trophy earning for that save file, but the game remains fully playable. Mods are not available on console versions at all.

Can I edit relationships between sims who are not in my household?

Yes, but only if they are in your neighborhood or have visited your lot. The mod and cheat console can only modify relationships for sims that exist in your save file. If a sim has never been to your lot, they do not have a relationship value yet and you cannot edit it.

What happens if I set a relationship to 100 or -100?

Setting a relationship to 100 means the sims are at maximum friendship or romance — they will have the most positive interactions available. Setting it to -100 means they are at maximum dislike — they will refuse to interact positively and may fight. Both extremes are stable and do not change unless you interact with the sims.

Do I need to update the mod when The Sims 4 gets patched?

Usually yes. When The Sims 4 releases a major patch, mods often break because the game's code changes. The mod creator usually releases an updated version within a few days. You can check ModTheSims to see if an update is available, or you can use the cheat console method instead while you wait for the mod to be updated.
