How does happiness work

kittens-game

In the tab Small Village in the Kittens Game, there is an option to send hunters (when there is enough catpower available) with a happiness percentage in front of it. How is this happiness calculated or influenced by me, and what effect does it have on anything (probably the resource gathering from the send hunters option?)?

Best Answer

Happiness goes down by 2% for every kitten you have after the fifth kitten (so the sixth kitten will drop it by 2% from 100% to 98%)

Happiness is the efficiency of your kittens. For example, a farmer (without any upgrades) normally will yield exactly 1 catnip per tick, but at 98% happiness they'll only yield 98% of that (0.98 catnip per tick)

Hunters can bring in items from the forest (I've only seen fur and ivory), each will increase the happiness by exactly 10%, cumulative (getting both increases by 20%). The amount of each of them only affects how long the bonus lasts, not how many the happiness bonus is

EDIT: Also, Amphitheaters reduces unhappiness by 4.8% each, which means that it will negate the happiness reduction effect by overpopulation, but can't actually increase happiness (so if you have only ever had 5 kittens, it will not increase the happiness)

EDIT 2: In reality, it looks like that as of v 0.9.6 Amphitheater does not actually reduce unhappiness by 4.8%. I have 18 kittens for a projected happiness level of 74%, unicorn raises it to 84%, yet 7 amphitheaters only brings it to 93%, about 1.8% each. I'll see if I can find more on this
