[ASK] How do we modify specific diet for a race?

[deliveryservice]

I wanted to add an Item designed to be an only diet for my unique race. But after a while I thought it would necessary to add new diet type (in racedef).

Based on the existing diet, I observed we have,
1. the carnivore (for Carnivore animal i.e dogs, consisting any meats nutrition, but also meals and kibbles),
2. strict-carnivore (For warg that prefer raw meat, especially corpses, and kibbles),
3. herbivore (For the cattles), and
4. the omnivore (For vanilla colonist).

The ultimate question I ponder about is;

Is it possible to make them, say eats only rotten corpses or maybe nutrient paste by modding the xml only?

According to the source code, these are all the available possibilities for the foodType xml entry:

None = 0,
VegetableOrFruit = 1,
Meat = 2,
Fluid = 4,
Corpse = 8,
Seeds = 16,
AnimalProduct = 32,
Plant = 64,
Tree = 128,
Meal = 256,
Processed = 512,
Liquor = 1024,
Kibble = 2048,
VegetarianAnimal = 3345,
VegetarianRoughAnimal = 3409,
CarnivoreAnimal = 2314,
CarnivoreAnimalStrict = 10,
OmnivoreAnimal = 3355,
OmnivoreRoughAnimal = 3419,
DendrovoreAnimal = 2193,
OvivoreAnimal = 2336,
OmnivoreHuman = 1855

So probably the closest you could get to "Rotten corpses and nutrient paste" would be:

Code Select Expand

<foodType>Corpse, Processed</foodType>

Foodtypes are computed by adding their numerical values together to get a unique number. Everything after Kibble is just a "group" of other previous types. So some of these like "CarnivoreStrict(10)" is exactly the same as "Meat/2 + Corpse/8 " = 10. CarnivoreAnimal/2314 is the same as Kibble/2048 + Meal/256 + Corpse/8 + Meat/2... etc.

Thank you Thirite, sir! This is useful, very!
Now I wondered about new things which is if the strings in foodtype, has related tag to use in fooddef to make the system think it's part of a certain foodtype. But I think I can do small research on my own.

That unique arithmetic method of defining a diet seems interesting, I thought at first they were primary number at least not the one that is a sum, but it wasn't, they hide a secret pattern it seems

Edit: nvm, it was 2x (or rather 2(n-1))

it is a eleven bit BINARY bit pattern
eg 00100100100
the clue from the kibble of 2048(binary 10000000000) sets the maximum limits of the flag size

Interesting it seems to have a limit. But compared to using class, or array function, it's relatively compact. I love it.
