Igloo walls will start melting if the "ambient temperature" of the wall is above 0C. Ambient temperature is a vanilla game concept that factors in the temperature of adjacent cells, so if one side of the wall is 20C and the other side is 0C, the wall will have an effective temperature of 10C and start melting. In my games I've actually found that my colonists are more comfortable in the winter because it's colder outside, so it allows for a warmer inside temperature without melting the igloo. In the summer where it's barely below freezing, you can't really have a heated igloo.

I'm definitely planning to verify the ambient temperature logic before updating this for 1.6 as things could have changed in the base game engine.

And by melting, i mean around 20 ish a day

For some odd reason my igloos are melting? The inside is 20 degrees, but the outside (Which is ambient temperature i assumed) is well below 0C

Updated for 1.5!

@Arky - I had the same concerns when I implemented this. Looking through the code it seemed that the item deterioration loop was designed in order to minimize performance impacts, for instance by using an RNG trigger rather than a micro-counter to determine when an item should take damage, so I decided to leverage that same mechanic. Melting in my mod is essentially just another source of deterioration damage.
@Doctor Neetzow - I'm probably the wrong guy to ask about mods. I like to keep my games as vanilla as possible, and even now I only play with my own couple of mods. For a good time I'd recommend just turning down the temperature and settling near the poles.

How performance intensive it is if it has to check for melting every time?

Hey dear author, I want to first say thank you for taking upon yourself the endeavor to make an ice-biome gameplay friendly modpack.
I'm in love with the idea of surviving those since frostpunk.

I'd like to ask you 2 things:

1st) What are the configs you use/recomend to set up such gameplays in Rimworld (I'm realatively new to the game... added several mods, but never knew how to mess with game configs very much)

Pt 1/2

2nd) I wanted to play 2 scenarios related to freezing landscapes, and I wonder if I'd need more mods for those:

A) An "snowball earth" scenario, with little to no wildlife scenario... probably only moss on the equator or something like that... Maybe fish?

B) An "nuclear winter" scenario, with just a few spots with "less radioactive" environment, but fronzen cold as a trade-off, with nuclear fallout places, and lots of ruins in the sententrional regions of the map.

>>>> In case it's not possible to set up such gameplays with existing vanilla/mods, would you consider picking at least one of those to your To-do list? Sorry for being a nuisance.

pt 2/2

Can you make this compatible with the Soil Relocation Framework? It allows for the collection/removal of Ice, as well, plus more.

Might I suggest having the walls and possibly the bricks cool rooms down to just above freezing if you were to have them in a room on a warmer map? In theory this would help with food preservation for low tech starts in locations that experience seasons.
