How to make a character hibernate depending on the temperature?

[Greyan777]

Hello, this is my first time on this forum and also my first time doing a mod. I'm quite new to this. 
Let me explain the situation a little bit:
My character is cold-blooded and, in theory, he should fall asleep at a low temperature. So, how to make it so that at a low temperature (zero degrees) he falls asleep, and wakes up when it rises? Non-seasonal hibernation (not in winter), it is at low temperatures.
I've read a lot of the game files, but I haven't found anything similar in them, which is why I don't have the slightest idea how this can be done(

So your character would sleep indefinitely until temperature rises above 0? Sounds bad in terms of gameplay experience tbh.

If it's not permanent sleep, they would still stuck in a loop: too cold - sleep - wake up - still cold - sleep again.

It's certainly possible but it would be buggy, could you go in details about this mechanic?

Okay, wait a minute. 
Ahem, the idea of this character belongs to my co-author and he would like the reptile to fall asleep at a negative temperature. That is, until she rises, the character would sleep (perhaps this can be considered an endless sleep until someone warms him up. That is, he would not fall asleep, wake up and so on again). I mean... yes. Playing for him, you would have to monitor the character's body temperature more closely in winter (prepare an insulated hoodie, a thermal stone, maybe materials for a campfire with you just in case). Perhaps it would be more designed for coop, so that if anything in winter there would be someone who could warm it up. Something like that.. 

But if it really is going to be quite buggy, then I'd be interested in how it could be optimized (without loss as such, if possible)
(I use a translator, so I apologize if there are any mistakes ><")

You can do it like this in your character prefab file

local function master_postinit(inst)
  local temperature = inst.components.temperature
  local onupdate = temperature.OnUpdate
  temperature.OnUpdate = function(...)
    -- If the character is freezing but not sleeping, make it sleep
    if temperature.IsFreezing() and not inst.sg:HasStateTag("sleeping") then
      inst.components.grogginess:AddGrogginess(3, 60) -- The second parameter is the time to sleep in seconds.
    end
    onupdate(...)
  end
end

Hm.. I tried to do it in the file, there were no errors, which is good, but.. he does not fall asleep, even grogginess does not appear. I tried changing the numeric values, but the character just freezes and no more
I can roughly read the code and have an idea how it should work, but I don't quite understand what needs to be fixed to make it work

[Greyan777]

I didn't quite understand how the function above works (or rather why it doesn't work), so I tried to find other solutions. After digging through the files, I achieved something like this:

inst:ListenForEvent("temperaturedelta", function(inst,data)   
        if inst.components.temperature.current <= 0 then    
            inst.components.grogginess:AddGrogginess(3, 10) 
        end 
 end)

Yes, he is not waking up now, in the future I will add the opposite event to this (if possible), but I have a question again.. When the temperature reaches 0 degrees, the character falls asleep instantly. I would like him to look sleepy for a while at first, and then fall down. Is there anything you can add or change?
I'm very tight in this regard, but I really want to do something(
