Sims 4 relationship cheats
Updated 8 commands
One command covers nearly all of this. Type testingcheats true first, then modifyrelationship with both Sims' full names, a number, and the bar you want to move: LTR_Friendship_Main for friendship, LTR_Romance_Main for romance.
Both bars run from -100 to 100. The number you type is added to the score that is already there, and anything past either end is clamped, so 100 from a standing start fills the bar and -100 empties it.

Turn cheats on first
Two steps, and the second one is the one people forget.
Open the console with Ctrl + Shift + C on a Windows PC. On a Mac, try the same shortcut first and then Command + Shift + C, because EA's own FAQ and the community guides disagree about which one applies. On PlayStation, hold R1, R2, L1 and L2 together. On Xbox, hold RB, RT, LB and LT.
Then type testingcheats true and press Enter. Relationship commands sit squarely in the group that EA gates behind that switch, alongside the skill, career, trait and stat commands. Without it, the console accepts what you type and nothing changes.
Every relationship cheat
Copy the line, swap the names and the number, press Enter.
Friendship and romance between two Sims
One command does all of it. Name both Sims, give it a number, then say which bar you want to move.
| Command | What it does | Notes | Copy |
|---|---|---|---|
Commandmodifyrelationship <Sim1First> <Sim1Last> <Sim2First> <Sim2Last> <value> LTR_Friendship_Main | What it doesAdds that value to the friendship score between the two named Sims. | NotesNeeds testingcheats true. Both Sims need a first and a last name, spelled exactly as the game spells them. PC, Mac, Xbox, PlayStation. | |
Commandmodifyrelationship <Sim1First> <Sim1Last> <Sim2First> <Sim2Last> -<value> LTR_Friendship_Main | What it doesSubtracts from friendship.

Commandmodifyrelationship <Sim1First> <Sim1Last> <Sim2First> <Sim2Last> <value> LTR_Romance_Main | What it doesAdds that value to the romance score between the two named Sims. | NotesNeeds testingcheats true.

Sims and pets
The same command, with the pet in place of the second Sim and a different bar name.
| Command | What it does | Notes | Copy |
|---|---|---|---|
Commandmodifyrelationship <SimFirst> <SimLast> <PetFirst> <PetLast> <value> LTR_SimtoPet_Friendship_Main | What it doesChanges the friendship between a Sim and a pet. | NotesNeeds testingcheats true.

CommandShift-click an animal > Cheat relationship > Set max friendship | What it doesMaxes your relationship with an animal from the shift-click menu. | NotesNeeds testingcheats true. Cottage Living only. No typing and no names to spell. On console, shift-click is Circle and X, or B and A. PC, Mac, Xbox, PlayStation. |
Meeting Sims and filling the relationship panel
Two commands that create relationships rather than adjust the ones you already have.
| Command | What it does | Notes | Copy |
|---|---|---|---|
Commandrelationship.introduce_sim_to_all_others | What it doesIntroduces the active Sim to every other Sim in the world, so they all appear in the relationship panel as acquaintances. | NotesThe prefix is singular here. Turn cheats on first if nothing seems to happen. PC, Mac, Xbox, PlayStation. | |
Commandrelationships.create_friends_for_sim | What it doesSpawns a brand new Sim on the lot who is already a friend of the active Sim. | NotesThe prefix is plural here. Repeat the command to spawn more. Turn cheats on first if nothing seems to happen. PC, Mac, Xbox, PlayStation. |

How the scale from -100 to 100 works
Friendship and romance each sit on a scale that runs from -100 at the bottom to 100 at the top. The bar you see under a Sim's portrait in the relationship panel is that number drawn as a line, with the midpoint at zero.
The number in the command is added to the current score rather than replacing it. Two Sims sitting at 40 friendship who get a 30 end up at 70. Values that would push the score past either end are clamped, which is why most players just type 100 or -100 and let the game do the arithmetic.
There is no separate command for each stage of a relationship. Friendship is one score, so raising it far enough carries the relationship along with it, and romance is a second score that behaves the same way on its own.
A worked example. To make two Sims best friends and nothing more, enter modifyrelationship Bob Pancakes Eliza Pancakes 100 LTR_Friendship_Main and leave the romance bar alone. To make them a couple, run the same command again with LTR_Romance_Main on the end.
Getting the two names right
This is where the command fails, and it fails without saying so.
modifyrelationship takes four name arguments: the first and last name of Sim one, then the first and last name of Sim two. A space separates each argument, which means a Sim whose surname has a space in it cannot be typed as one word and cannot be typed with the space either.
When a name is wrong, the console does not complain. It accepts the line and nothing happens, which sends most people looking for a problem with the cheat rather than with the spelling. Before you retype the command, check three things: the exact spelling in the relationship panel, whether the Sim has a nickname you have been using instead of their given name, and whether two Sims in the save share the same full name.
Capitalisation is not part of the problem. Cheat codes in The Sims 4 are not case sensitive, so bob pancakes and Bob Pancakes behave the same way.
If you need a Sim who is definitely reachable, run relationships.create_friends_for_sim. It spawns a new Sim on the lot who already counts as a friend, which is quicker than tracking down a townie and typing their name. To fill the relationship panel with everyone in the world at once, use relationship.introduce_sim_to_all_others. Note the singular relationship in one and the plural relationships in the other. That inconsistency is in the game, not a typo.
Sentiments, dynamics and relationship bits
Sentiments can be attached to a modifyrelationship command by appending the sentiment token, but Sims Community records that doing so needs TwistedMexi's AllCheats mod rather than the base game. There is no vanilla console command for them, so anything you see presented as one is really a mod feature.
That leaves two honest options. Play the sentiment out in game, or use a mod that exposes it. The UI Cheats Extension is the lighter of the two: right-clicking the green Sentiments title bar in a Sim's profile adds one, right-clicking a sentiment removes it or sets its value from 0 to 100, and the same pattern covers relationship bits under the green Relationships title bar.
Console and platform differences
The commands are identical on all four platforms. What differs is how you reach the console and what it costs you.
On PlayStation and Xbox you open the console by holding all four shoulder buttons, and you type with the on-screen keyboard. Shift-clicking, which you need for the Cottage Living animal option, is holding Circle and pressing X on PlayStation, or holding B and pressing A on Xbox.
Console players have no mods at all. The Sims 4 on PlayStation and Xbox does not load script mods, so the typed command is the only route to a relationship cheat there. That is covered in full on whether UI Cheats works on console.
Achievements and trophies
On PlayStation and Xbox, any cheat that needs testingcheats true turns off achievements and trophies for that save. Relationship cheats are in that group, so using one costs you the trophies in the save where you use it.
The penalty is per save, not per account. Other saves keep earning normally, which is why a common approach is one save for trophy hunting and another for building the family you actually wanted. Build mode cheats are the exception to the rule: EA states plainly that those do not disable achievements.
The same thing in one click with UI Cheats
On PC and Mac, the UI Cheats Extension turns this into a right-click. It is a free script mod by weerbesu that makes the game's own panels respond to clicks, and the relationship panel is one of the panels it covers.
Inside the relationship panel:
- Right-click a Sim to set friendship or romance anywhere from -100 to 100, delete the relationship outright, or remove the romance bar.
- Right-click the icon that opens the relationship panel to add any Sim to it, including one your Sim has never met.
That covers the ground modifyrelationship covers, with two names fewer to spell and no silent failures. Deleting a relationship and removing a romance bar have no console equivalent at all.
See every UI Cheats click, panel by panel for the rest, including the sentiment and relationship bit cheats in the Sim profile. If you do not have the mod yet, start with how to install UI Cheats.
If a relationship cheat does nothing
Work through these in order. The first two account for most cases.
- Enter
testingcheats trueagain. It does not survive loading a different save. - Check both names against the relationship panel, letter for letter, including the surname.
- Check that you typed the bar name exactly:
LTR_Friendship_MainorLTR_Romance_Main, with underscores and no spaces. - Check the number. A bar already at 100 will not visibly change when you add more to it.
- If the console itself will not open or refuses every command, the problem is not this page. Go to the fixes for Sims 4 cheats not working.
If you are using the UI Cheats Extension and the right-click does nothing, the mod is the thing to check rather than the game. That has its own walkthrough on fixing UI Cheats when it stops working.
Frequently asked questions
What is the relationship cheat in The Sims 4?
It is modifyrelationship. You give it both Sims’ full names, a number, and the name of the bar you want to move: LTR_Friendship_Main for friendship or LTR_Romance_Main for romance. Turn on testingcheats true before you use it.
How do you max out a friendship in The Sims 4?
Use 100 as the value. From a standing start, modifyrelationship Bob Pancakes Eliza Pancakes 100 LTR_Friendship_Main fills the friendship bar in one go, because anything past the top of the scale is clamped to it.
Can you make two Sims hate each other with a cheat?
Yes. Put a minus sign in front of the number: -100 takes the friendship bar to the bottom of the scale. Romance works the same way, so you can drop a romance to its floor without staging a fight in Live mode.
Does raising friendship also raise romance?
No. Friendship and romance are two separate bars with two separate command arguments. Run the command twice if you want to move both.
Why does my modifyrelationship cheat do nothing?
Almost always a name. The command needs the first and last name of both Sims, spelled exactly as the game spells them, and it fails silently when one is wrong or when two Sims in the save share a name. The other common cause is forgetting testingcheats true.
Can you cheat a relationship with a pet?
Yes, with Cats & Dogs. Use the pet in place of the second Sim and end the command with LTR_SimtoPet_Friendship_Main. With Cottage Living you can also shift-click an animal and choose Cheat relationship, then Set max friendship.
Do relationship cheats work on Xbox and PlayStation?
They do. Hold all four shoulder buttons to open the console, then type the same command. Because it needs testingcheats true, using it disables achievements and trophies in that save.
