Step 2: Understanding the ModifyRelationship Syntax

The main cheat command has a specific structure that you must follow precisely. If you mistype a Sim's name or the relationship type, the cheat will fail.

modifyrelationship [SimAFirstName] [SimALastName] [SimBFirstName] [SimBLastName] [Number] [RelationshipType]

Here is a breakdown of each entity in the command:

• [SimAFirstName] [SimALastName]: The full name of the Sim you are controlling.
• [SimBFirstName] [SimBLastName]: The full name of the Sim you are targeting (the Sim whose relationship bar you want to change).
• [Number]: This is the relationship score you want to add or subtract. The valid range is -100 to 100. Use 100 to max out the bar instantly, or -100 to make them instant enemies.
• [RelationshipType]: This is the specific code for the type of relationship bar you want to affect (Friendship, Romance, or Pet).

Expert Tips for Advanced Relationship Cheating

While the modifyrelationship command is incredibly powerful, there are a few nuances and LSI keywords that expert players use to fine-tune their gameplay and avoid common pitfalls.

Understanding Relationship Titles vs. Relationship Scores

It is important to understand what the cheat does and does not do. The modifyrelationship cheat only affects the relationship score, which is the numerical value (from -100 to 100) that governs the green (friendship) and pink (romance) bars. It does not change the fixed family relationship title (e.g., Mother, Brother, Aunt, Cousin).

If you want to change a Sim's actual family tree title (e.g., make two unrelated Sims siblings), you will need a popular community mod like MCCC (MC Command Center). In vanilla (un-modded) gameplay, you must use the 'Add Family Relationship' option in Create-A-Sim (CAS) to set these titles.

Using Shorter Values for Fine-Tuning

While 100 is great for a quick max-out, using smaller values like 10 or 20 can give you more control. For example, if you want to push a friendship from 'Good Friend' to 'Best Friend' without maxing out the bar entirely, you can use:

modifyrelationship SimA SimA TargetSim TargetSim 15 LTR_Friendship_Main

This allows for more natural-feeling relationship progression in your storytelling.

Troubleshooting Common Cheat Errors

If your cheat is not working, check the following:

• Did you enable cheats? Re-type testingcheats on.
• Spelling and Capitalization: Ensure all names and the RelationshipType code (e.g., LTR_Friendship_Main) are spelled correctly, including capitalization.
• Sims Must Exist: Both Sims must be in your game's world and known to the Sim you are controlling.
• Pet Names: Remember that for pets, you only need the pet's first name unless they were given a last name.

By mastering these Sims 4 relationship cheat codes, you gain the power to craft complex, detailed, and instantly gratifying social narratives. Whether you are creating a bitter rivalry, a whirlwind romance, or an unbreakable family bond, these cheats are the key to unlocking your full storytelling potential in The Sims 4.
