Happy

Happy is an emotion available in The Sims 4. It occurs when a Sim performs a positive interaction, succeeds in an interaction or enters a room with wall decorations.

Interactions and Activities
Sims will only have a chance to use these interactions and do these activities while happy.

Supportive Traits
These traits affect how often a Sim is happy.

Object Auras
These are items found, bought, or earned in the game that can emit a happy aura in the area around the object. Players can choose to enable or disable the aura at any time. Once enabled, a Sim can interact with the object, through viewing or using it, and they will earn a happy moodlet. Whether their mood changes to happy or not depends on the other moodlets affecting the Sim at that time.

Careers and Jobs
Sims with these jobs or careers will gain work performance if they go to work while happy.
