All those moodlets add up to an emotion.
To understand emotions, and what causes them, you first must understand moodlets. Moodlets are small effects that result from a variety of influences during a Sim’s life. They are usually short lived—only lasting a few hours or until a condition changes. There are more than a thousand moodlets in The Sims 4. Each is related to an emotion. Let’s take a look at what causes moodlets.
Environment
In addition to having a nicely decorated home, visit museums or other venues that can provide positive environmental moodlets.
A Sim’s surroundings can affect emotions—both for good or bad. Many objects have an environment value such as paintings and decorations. Living in a home, or visiting a venue with these objects, can help put Sims into a good emotion by receiving positive moodlets. Traits can also play a role in this. Neat Sims get a positive moodlet when in a clean environment and a negative moodlet when their surroundings are messy. Slobs are just the opposite. Going outdoors or indoors can also affect some Sims based on their traits.
Some objects actually have an emotional aura that you can enable or disable. For example, if you catch a fish and then choose to mount it and hang it on the wall, you can provide a aura of confidence. This provides a Confident moodlet. Other objects exude a playful aura and so forth. By having several of these types of objects in your home, you can enable and disable them to help create the desired moodlets—and related emotions—for your Sims.

Needs
This Sim is very Uncomfortable due to all of her neglected needs.
Keeping all of your Sims’ needs in the green is an easy way to receive some positive moodlets. While these types of moodlets are usually Happy, they tend to bolster whatever positive emotion the Sim is already in. On the other hand, by neglecting your Sims’ needs such as Hunger, Hygiene, Bladder, and Energy, they receive Uncomfortable moodlets that can build up and overpower positive moodlets. Failure to maintain your Sims’ Fun need can result in Tense moodlets, while low Social need causes Sad moodlets. Luckily, these types of moodlets are short lived and quickly disappear once you take care of those needs.
Socializing
Socializing with other Sims provides a variety of different moodlets.
It is amazing how many moodlets your Sims can receive by socializing with other Sims. In fact, it is interesting to watch them appear and see how quickly they can change your Sims’ emotions. Most social moodlets are caused by the types of social interactions that you or other Sims choose. Friendly socials usually lean toward Happy moodlets. Romance socials lead to Flirty moodlets. Funny socials can create Playful moodlets while mischief and mean socials can cause negative moodlets. Because these moodlets affect both your Sims and those other Sims in the conversation, you can use this knowledge to help influence the emotions of other Sims.
Actions and Activities
Just watching television can provide moodlets to help you create an emotion.
Many of the activities your Sims do can cause moodlets. Catching a big fish can give your Sims a Confident moodlet. Taking showers, working out, watching television, or listening to music can provide different moodlets. Leveling up a skill or getting a career promotion can also provide positive moodlets. Many of these types of moodlets are related to a Sim’s traits. Doing actions that go along with the traits provide positive moodlets while actions that are contrary to a trait can result in negative moodlets. A Slob does not like to clean up. However, a Neat Sim finds great pleasure in cleaning.
Food and drinks can cause moodlets as well. A well prepared meal creates a positive experience and good moodlets. On the other hand, Sims new to the Cooking skill and using a basic stove might prepare meals that actually cause negative moodlets even though meeting the Hunger need.
Situations
Decisions you make while your Sims are at work can have emotional consequences.
Some moodlets don’t fit into the other categories. Some Sims can be affected by just being near other Sims doing things. If a Sim is next to someone playing an instrument badly, it can make a negative moodlet. Sims who have the Vicarious trait (from completing the Successful Lineage Aspiration) actually receive positive moodlets such as Focused or Inspired when their children level up in a skill.
When Sims are at work or somewhere off the screen—such as flying through space in a rocketship—you have to make some decisions. These can result in various outcomes that provide different moodlets for your Sims. Some of these are positive and others are negative.
