Template:Actual Age

Returns the actual age at which an animal will reach a life stage age listed in its def files.

Parameters

• adult_age - this has to be the adult_age listed in the animal's def xml, or seen in the in-game information window
• juvenile_age - if a second parameter is given, the number returned will be the actual juvenile age. This number must be found from the defs files.

Formula used

actual_juvenile_age = (1-1/e^(juvenile_age/adult_age))×adult_age

actual_adult_age = (1-1/e)×adult_age

Explanation

The reason this predicts the actual ages at which animals reach their life stages stems from how the amount the growth stat increases each tick is proportional to 1/ticks_to_adulthood, where ticks_to_adulthood is simply the def file's adult_age expressed in ticks.

The consequence of growth updating this way is that initially, the growth stat will increase slowly, and then as the animal approaches 100% growth, it increases faster.
