Moodlet

Moodlets are mood altering events or situations that a Sim has done or experienced. These moodlets may be positive, negative, or neutral. Some moodlets happen for an indefinite amount of time while others are timed. Some moodlets lead directly from one to the next, such as "Strained" leading to "Stressed Out", or "Sleepy" leading to "Tired" then "Exhausted", but all other moodlets are not mutually exclusive and so you can have "Vile Surroundings" and "Beautifully Decorated" at the same time, or multiple instances of "It's a Boy!"or It's a Girl!".

Moodlets that do not specify a time only end when certain events occur, such as leaving the area that gives the moodlet.

Moodlets may also have secondary effects, such as improving skill gain, making it easier to burn to death, or making a sim fatter when they eat, or to drown when swimming, to name a few.

Moodlets can be removed using the Moodlet Manager lifetime happiness reward. The manager is not perfect, and may affect the sim with a red beam causing negative effects instead of removing them.

Moodlets can also be removed when the testingcheatsenabled on command is used by ctrl+clicking them, removing need-related moodlets may cause the need to be refilled. This can also cause a glitch in the game, when a pregnant sim has the "baby is coming" moodlet and it is removed the baby will never be born and there is no option at the hospital to deliver the baby, also the sim will not be able to age up, exercise or maybe even die.

Ctrl+clicking negative or neutral moodlets when testingcheatsenabled is off will add the appropriate action to the bar. For example, ctrl+clicking the smelly moodlet will make the sim take a bath or shower, ctrl+clicking the sleepy moodlet will make it go to sleep, e.t.c.
