Relationships are a critical component of The Sims 4, influencing gameplay in various ways. You may be seeking to build a large circle of friends, a tight-knit family, or a romantic relationship with the Sim of your dreams. Unlike real life, The Sims 4 allows for intriguing relationships with non-human entities such as vampires, spellcasters, and ghosts. This guide will guide you through the process of editing relationships in The Sims 4 so that you can have the Sim life you've always desired.

Setting Up Initial Relationships

Setting Up Initial Relationships

Upon creating a new Sim, players can establish relationships with other Sims in the same household from the get-go. By default, every Sim is a standard roommate. However, you can set them as siblings, spouses, parents, and children, using the Household Relationships button on the character customization menu. This allows players to lay the groundwork for their Sim relationships right from the start.

Activating Cheats

Unpredictable and dynamic as they are, relationships in The Sims 4 can sometimes shift in ways you might not prefer. If you want to have more control over your relationships, you'll need to unlock the power of cheats. These codes alter the game to give you more authority and control over your Sim's world, including their relationships. Follow these steps to activate cheats:

  • On Windows - Press CTRL + SHIFT + C.
  • On PS4 and Xbox - Press all four bumper buttons.
  • On Mac - Press Command + Shift + C.
  • Type “testingcheats true” into the cheat box.
  • Enter “cas.fulleditmode” into the cheat window and press enter.

Editing Relationships

Editing Relationships

With cheats activated, editing your Sim's relationships is now possible. Press and hold the shift key, then left-click on the desired Sim. From the list, select 'Modify in CAS.' You can now edit the relationship dynamics of your Sim and their selected contact. Got a Sim you want to promote from friend to lover? Or perhaps a Sim you want to downgrade from friend to mere acquaintance? Here’s where all the magic happens.

Relationship Cheats

Beyond the CAS mode edits, you can direct your Sim's relationships using specific cheat codes. Here are some cheat codes to help guide your Sim's social life:

  • Use 'ModifyRelationship Sim1 Sim2 100 LTR_Friendship_Main' to increase friendship between two Sims.
  • 'ModifyRelationship Sim1 Sim2 -100 LTR_Friendship_Main' diminishes the friendship between two Sims.
  • Use 'Relationship ModifyRelationship Sim1 Sim2 100 LTR_Romance_Main' to boost romance between two Sims.
  • Relationship ModifyRelationship Sim1 Sim2 -100 LTR_Romance_Main weakens the romantic bond between two Sims.

Whether it's pursuing friendship or romance, these codes give you the power to influence your Sim's network of relationships, providing a unique spin and more control over gameplay.


Simulating life in The Sims 4 is an operational experience in relationships. By editing your Sim’s relationships, you can add a unique flavor to your gameplay, tailoring it to your precise preferences for the perfect Sim life. Happy Simming!
