Sorry for my English, but I really want to write this suggestion :)

Balance of Substances
Idea: make (but not force) Player to grow different types of food.

Can you add to your mod - balance of substances in the body?
Ie. each type of food adds a character, like a:
- vitamins (pink on GUI)
- minerals (pink on GUI)
- carbohydrates (blue on GUI)
- fats (blue on GUI) or something else.
Each of the existing products or any food in mod affects on the balance. This will require the player to use different dishes.

GUI picture (As I see it) https://www.dropbox.com/s/ospte7blkrkhi3b/Balance%20of%20Substances%20GUI.png?dl=0

Exsample: Scale on left and right = 10 points (or 100%, as more convenient for programming).
And: 1 baked-potato adds 3 vitamins/minerals, 0.5 carbohydrates and 0.5 fats
Or: 1 basic-salad adds 5 vitamins and 0.8 carbohydrates
Etc.

This balance affects:
1. Energy Usage, if the less balance from one side, then greater the energy consumption (+400%...+1000% additionally).
2. Rate of decrease Fullness, as well as Energy Usage but slower decreases of Fullness.
The balance impact factor can also be changed or completely disabled in the mod settings.

Thanks!

Баланс веществ
Идея: заставить (но не принудить) Игрока выращивать разные виды пищи.

Можете ли вы добавить к своему моду - баланс веществ в организме?
Т.е. каждый тип пищи добавляет персонажу, например:
- витамины (розовый на GUI)
- минералы (розовый на GUI)
- углеводы (синий на GUI)
- жиры (синий на GUI) или что-то еще.
Каждый из существующих продуктов или любая еда в моде влияет на баланс. Это потребует от игрока употребление разных блюд.

GUI (как я его вижу) https://www.dropbox.com/s/ospte7blkrkhi3b/Balance%20of%20Substances%20GUI.png?dl=0

Пример: Шкала налево или направо = 10 очкам (или 100%, как удобнее для програмирования)
И: 1 Запеченный картофель при съедании добавляет 3 витаминов/минералов, 0.5 углеводов и 0.5 жиров.
Или: 1 Салат - 5 витаминов и 0.8 углеводов.
и т.д. и т.п.

Данный баланс влияет:
1. Energy Usage, чем меньше баланса с одной из сторон, тем больше потребление энергии (+ 400% ... + 1000% дополнительно).
2. Скорость снижения Fullness, также использования энергии, но более медленное снижение Fullness.
Коэффициент влияния баланса также можно изменить или полностью отключить в настройках мода.

Спасибо!

I thought about this too, but I ended up making it simple, because I felt this was overcomplicating.

Yeah.. :( It's hard, but it will make the gameplay more interesting.

Let's go back to suggestion:
The consumption of vitamin and minerals depends on the mental activity of the Player (construction or disassembly). And fats and carbohydrates are expended from physical exertion (movement and shooting).
While the Energy Using is small and stable, but as soon as one of the balance scales is empty - the Energy is consumed quickly. Now the Energy Usage depends only on the movement of the Player, only the percentage of consumption is still increased by the armor.

I am sorry to say this, but I don't plan on updating this mod anymore. There is tons more to do, but I have moved on. Sorry

That's all right.
You are developing a new mod or something else? Sorry that such a wonderful mod will not continue its development.

There is his code in the public domain? May be someone else will continue.

p.s. And, I have new one small suggestion.

The code can be obtained by simply downloading the mod.
