Saturation is the unseen game mechanic that controls Characters' needs for Food. A character with a higher saturation value has eaten recently, and is more full than another character with a low saturation level.
Levels of Saturation
Characters' saturation level is grouped into four thresholds: Fed, Hungry, Urgently Hungry, and Starving. Each threshold exhibits different effects on a character, especially their Thoughts.
For humanoids, the saturation levels are as follows:
|Fed||Greater than 30||none|
|Hungry||20 to 30||-8|
|Urgently Hungry||0.01 to 20||-15|
|Starving||Less than 0.01||-25|
Saturation caps at 100.
Saturation goes down every tick (1/20000 of a game day) depending on the character's current saturation.
|Saturation||Change per tick||Change per day|
Once a character becomes starving they start a clock to take damage from starvation.
After 5000 ticks (1/4 game day) a starving character takes 5 starvation damage and the clock resets.
This means a character with 100 health (full) will die after 5 days of starvation.
Jones recently became hungry. His saturation is 25. He eats a Packaged Survival Meal which restores up to 100 saturation. His saturation caps out at 100.
Jones will become:
Hungry in 17500 ticks (0.875 game days)
Urgently Hungry in 17500 + 5000 = 22500 ticks (1.125 game days)
Starving in 22500 + 19990 = 42490 ticks (2.125 game days)
Dead in 42490 + 100000 = 142490 ticks (7.125 game days)
