Spice of Life and Enviromine are the mods you're looking for.
I'm not sure if i can or even should attempt to add mods to this mod pack.
I think Spice of life was in this mod pack before, but was removed, i didn't like how it artificially forced you to have different foods, i just want different foods to have different nutrients so you will on your own accord choose to eat many different meals to fulfill all your nutritional needs.
drink water when thirsty, eat food when hungry, wear clothes when cold, take cover in shade when over heated, all these are done withat enviromine i think?
Imagine being able to become obese or underweight in minecraft lol, i think it would be very enjoyable to micromanage this.
Spice of Life was in this modpack before but was removed after being disabled i think, all SoL does is punishing you for eating the same thing with diminishing returns, so you can still live with only candy.. just that you need to eat different kinds of candy.
So its not for me really, i want to learn things playing minecraft and diminishing returns doesn't teach me much, but learning how to get all the nutrients might have real-world benefits and fix the food values being hard-coded and all weird and stuff.
Enviromine i think i saw it when some youtubers was playing, might be worth a try if it can work with this modpack or not, not sure, but i'm more interested just in the nutrients in food.
Think of steve as a machine, this machine need a very specific ratio of nutrients to work properly... NOT, just needs wheat, wheat all day, all night, every time
What i would like would be a way to enjoy food in a more fulfilling manner, a dining table, a fork, a knife, a glass of vine, a plate with delicious food that you have worked hard for, lovely music playing in the background... heck this once in a day experience could give you just that!
Experience points!.. just one idea that is a little over the top but maybe you get my drift
Also enjoying cooking the food and acquiring the ingredients.. no more inventory clottering.. you actually have a kitchen where you can easily cook food without clottering your inventory and making you run around everywhere for ingredients.. it might just be that my "kitchen" sucks and needs a remake lol.. we do have a furniture mod, maybe i should give it a shot, but i want real benefits for doing things this way, like i said before: experience points could be an appropiate reward.
Also a way to enjoy food more easily on the go (well this is the big point), food just take up too much space, i have like 30 chest blocks just for food and i still don't have enough space for it, my steve is walking around with 4 bags, not enough space for different foods.. i could have a dedicated bag for food though.. those project-red bags isn't compatible with inventory tweaks, making them annoying to move stuff into/out of, i don't like dealing with them, is there better bags with inventory tweak compatibility?
What we need is more equipment slots for steve, that doesn't use the main action bar. too many things fight for control of the action bar, what i would love the most would be a mod that gave us more slots that can be keybinded into any key you want, think an MMO where you only have 9 buttons to press... then look at WoW where you have like 100 buttons (i don't really play wow but i see it very often).
I want to press T to place torch, i want to press X to bring out my weapon i want to press a lot of weird keys for different stuff and i would have a lot more action bar slots for random stuff like different foods, tho optimally food would have a dedicated button and inventory all of it own so it will give you 0 inventory clutter, a mod like this would be GOLD for me.
