In Sims 4 you can use screenshots to create memories then recall them to get that emotion! Steps below on how! Playalot had mentioned this feature I was not aware of over on the Emotions Thread. I said I would make a guide about it so here it is
Step 1) Locate the camera button in the top right of your screen then click the small Polaroid Icon (Memories & Pictures)
Step 2) click (View Screenshots) button in the bottom left corner
- This will take some time if you have a ton of screenshots! -
Step 3) Select a screenshot you want to use
Step 4) You can add a description or whatever you want. Then click the icon to the left of the Trash Can
Step 5) You should be taken back to the main Memory Timeline you are now going to want to select your new memory
Step 6) You should now be able to select Angry, Embarassing, Inspiring, Confident, Romantic, Sad, or Happy from the list in the top right then press the check mark to accept it
Step 7) At any time you can choose the cloud icon and Reminisce about the memory!
Your Sim will que up this action. In total the process is very quick (about 15-30 seconds) then you will get an emotional buff of whatever the memory had associated with it.
