This is a bit too much, but thanks i will look into the mods.
Do you have it's name?

In version 0.4.2.4 the speed at which they try to get pregnant is mainly driven by the hunger level.

The hungrier they are, the faster the pregnancy timer goes.

High nutrition food (cooked meat, cooked pumpkin) usually reverses the pregnancy timer, because sapiens try to eat when they're >60% hungry and these foods provide 70% and 80% satiation.

But it seems there's an update today so maybe this already changed

I believe you meant <60% ;)
No, the update did not address this since it was just to fix some things that needed fixing.

True, they start eating when their need of need.types.food is moderate (>0.6) and they keep eating until it is lower than mild (<0.3).


At least that's what i observed, they always eat two berries at a time (0.3 food) but they only eat one peach (0.5 food)

Thanks for the coding.
What is the coding where hunger relates to increased rate of pregnancy though?

What is the coding where hunger relates to increased rate of pregnancy though?

It's in longWaitInfrequentUpdate in serverSapien.lua. It first checks if sapien isFemale, not a nomad, it's an adult, but not too old, loyalty is at least mildNegative, and it's not very very hungry and then accumulates a value that goes from 0 to 1, populationMultiplier curves the population, speedMultiplier multiplies by the food need and dt by the time elapsed between updates:


After that when pregnancyOrBabyTimer reaches 1 it tries to find a mate to make babies which can fail.

This update runs multiple times during the day, and since population is usually constant the most important factor is hunger, the hungrier the sapien the faster the pregnancies (up to a limit)

Fun fact: If this value reaches 1 while the sapien is sleeping it decreases randomly, can't try to get pregnant while sleeping. Maybe it should pause when sleeping, the food need timer seems to pause in that case.

That's cool, it's nice nuance to how the game tick is increasing the timer! You should do an edit to the wiki, I had this article written as a start that could use some refreshing or start another pregnancy page on it's own:

I'm confused. Are you saying that a well fed sapien is LESS likely to get pregnant?
If that is the case, then having a food surplus will mean fewer pregnancies, while having a food shortage will mean more. That just seems backwards to me. Completely backward.

What am I missing here?

I agree, it is even contrary to scientific evidence because starving populations have lower reproduction rates than well-nourished...
Means that we should block access to food to let the tribe grow! Weird...
