Bladder is a basic motive (also known as a "need") for Sims, pets and other life states in The Sims series. The bladder motive gradually decreases throughout the day, but is also decreased when eating or drinking. Using a toilet or other designated object causes the bladder motive to rise (i.e. relieves the need). If bladder is ignored, it will eventually become urgently low, and an accident can occur if the need is not resolved soon enough.
Bladder motive decreases naturally throughout the day, and can only be increased by going to the toilet. For males, the level of the bladder meter controls whether they sit or stand while using the toilet. In The Sims and The Sims 2, upgrading to a better toilet can let Sims boost Comfort if they sit while relieving themselves. If a Sim's bladder starts to get full, they become extremely cranky; when it gets to the red, they make a wild dash for the toilet with urgency, and if they can't get there in time, the poor Sim has an embarrassing accident on the floor, which will severely affect the Sim's Hygiene bar. In The Sims and The Sims 2, drinking a cup of coffee can make the bladder meter decrease. In The Sims 3 and The Sims 4, drinking anything decreases the bladder meter. If Sims do not flush the toilet, it can eventually become clogged, resulting in a mess that someone will have to clean up.
In The Sims 2 and The Sims 3, Sims have to train toddlers in order to let them use the potty by themselves. They will wet themselves if not potty trained. An older Sim can click on the potty chair and potty train the toddler.
As a rule, community lots will have public toilets of some sort. In The Sims 2, Knowledge Sims and/or neat Sims may occasionally have a minor fear of using a public toilet. "Having an accident" is a fear in The Sims 2, though it takes away more influence than aspiration.
In The Sims 2, outgoing and sloppy Sims are also able to "use" shrubs and the AquaGreen Hydroponic Garden to relieve their bladder needs. Sloppy Sims will also pee while taking a shower if their bladder need is low enough. Sims that wet themselves during a party will get the "Had an Accident at a Party" memory.
In The Sims 2, bladder failure can be associated with two negative memories.
|Image||Memory Name||Type||Cause||Game Dialog/Description||Notes|
|Had an Accident||Negative||Having a bladder failure.||I'm so embarrassed I think I'll crawl into a hole... or at least a shower.||If this motive is caused by the scare of a ghost or a vampire peek, then this memory will not be received. The Hygiene motive instantly depletes as a result.|
|Had an Accident at a Party||Negative||Having a bladder failure at a party.||That's the most embarrassed I've ever been! How can I ever show my face at a party again?||This memory only appears the first time this motive happens at a party. Anytime else it happens, the regular "Had an Accident" memory will be received.|
The Sims 3Edit
In The Sims 3, the Steel Bladder lifetime reward makes it so that Sim who purchased it no longer has to use the bathroom again. Sims will wet themselves if the "Really has to Pee" moodlet expires and gain an "Embarrassed" moodlet for wetting themselves, which gives -20 mood for 3 hours; and their hygiene drops to 0.
|Image||Moodlet Name||Mood Effect||Time Period||From||Game Dialog/Description||Notes|
|Has To Pee||No Mood Effect||2 Hours||Low Bladder Need||Your Sim needs to go. Like, "go."||Switches to Really Has To Pee after duration expires. Steel Bladder Lifetime Reward prevents and eliminates this.|
|Really Has To Pee||-30||60 Minutes||Critically Low Bladder Need||The bladder situation really has only gone from bad to worse, find a bathroom soon!||When duration expires, Sim pees him/herself. If they pee themselves, it will cause them to have the "Embarrassed" moodlet if other Sims are in the room (unless they are a toddler or infant) and will instantly deplete the Hygiene need, causing the Sim to be "Smelly". Accidents also may cause a small drop in the Fun need. Timer will freeze when sitting in a car. Steel Bladder Lifetime Reward prevents and eliminates this.|
The Sims 4Edit
In The Sims 4 Sims will likewise wet themselves when the "Really Has To Go" moodlet expires, and will then get the "Peed Self" moodlet and be Very Embarrassed for 4 hours. Sims that wet themselves in a swimming pool get a special positive moodlet instead.
In The Sims 4, the Steel Bladder Lifetime Reward prevents the bladder need from going down normally. It is still possible for the meter to go down by drinking.
