Building friendships and romance in The Sims 4 can be a bit tiring, so players often cheat themselves. Luckily, the following tricks should work for both PC / Mac and Playstation 4 and Xbox. You need to get the syntax correct, but I'm here to help.
Awards Ctrl + Shift+ C to open the cheat console, a small command line in the top left corner of the screen. On console, press all four triggers (L1 / L2 + R1 / R2) to do so.
Once open, just type in the commands and press Enter. We will use the ModifyRelationship YourSimFirstname YourSimLastname Sim2Firstname Sims2LastName # Relationship_Type - see below for explanations. Test tricks can be deactivated for these, but you can try activating them if you have problems.
Relationship types: romance, friendship and friendship between Sim and pets
There are three types of friendship. They can range from -100 to +100. A 0 value is neutral, while a +100 means I really like you or for +100 romance, I really love you. Negative values can make Sims enemies.
- LTR_Friendship_Main - normal Sim to Sim friendship
- LTR_Romance_Main - Sim to Sim romance
- LTR_SimtoPet_Friendship_Main - A Sim's relationship with a pet (The Sims 4 Cats and Dogs Only)
Friends and Enemies Cheats
For examples of how to use this, I have two Sims here. My Sim's name is Ashley Payne, the target is Yuki Behr. So to make them enemies, I would use ModifyRelationship Ashley Payne Yuki Behr -100 LTR_Friendship_Main and I get this result, a completely red friendship bar - real enemies:
If I then wanted to take them out of the hole, I would have to add 200, because it is negative. 100 would be fine if it were neutral, but to maximise it I'll use ModifyRelationship Ashley Payne Yuki Behr 200 LTR_Friendship_Main.
This is useful if you want a boy or girl right away or just to woohoo with another Sim to try out for baby. To maximise their romance bar, I'd use ModifyRelationship Ashley Payne Yuki Behr 100 LTR_Romance_Main. Remember, even romance can become negative! For example, with -100 romance and -100 friendship, two Sims are total opposites. If they have a positive romance but a negative friendship, they can be labelled as "Enemies with Benefits.
On the basis of all this, you should have no problem deceiving your friendship with a pet. If the dog's name was Duke Eats The Garbage I would use it ModifyRelationship Ashley Payne Duke EatsTheGarbage 100 LTR_SimtoPet_Friendship_Main.
I hope this helps!
