Of the six motive bars present in the Sims 4 (hunger, bladder, energy, fun, hygiene, and social) environment is absent. This is nothing new, as the environment bar was absent in the Sims 3 as well. In the Sims 3, the environment bar was replaced with moodlets. If your Sim was in an area with lots of decorations, they’d get a positive moodlet, and if they were in a pig sty with lots of dirty objects, they’d get a negative moodlet. The Sims 4 incorporates environment-as-moodlets in a similar manner, but gives the whole system some major enhancements along the way.
