[RF] Permafrost [1.0]

MOD Desc
‘Permafrost,’ as you’d probably guess, adds a new biome to the game. Permafrost exists on the border between tundra and ice sheets. The ground is permanently frozen, and much of it is covered in ice, but unlike the ice on ice sheets, the ground ice here is at most a few meters, rather than kilometers, thick. There is little vegetation beyond scrub brush, and few animals.

Additionally, the mod also allows water to freeze. This means that lakes, rivers and marshes in any biome will slowly ice over when the temperature drops below freezing, and only thaw again when the temperature rises. It also means that ground ice in permafrost biomes will (very) slowly advance and retreat with temperature changes. (If you don’t like this feature, it can be disabled in the mod’s ‘options’ menu.)

Note that if you have a fishing spot (whether from my own ‘Fishing’ mod, ‘Thanks for All the Fish,’ or ‘ZARS Simple Fish’) located on a water tile that freezes, the fishing spot will be destroyed. You can’t fish through ice. Fishing piers from ‘FishIndustry’ are not impacted, though, and neither are shellfish traps from ‘Fishing,’ since they’re actual buildings with material costs.

I wouldn’t expect this mod to conflict with any other mods.

‘Permafrost’ can safely be added to a game in progress, though obviously, it won’t add new biomes to an already-generated map. Trying to remove the mod from a game in progress, however, would be ill-advised.

If you’re a modpack maker and want to include ‘Permafrost’ in your pack, or if you’re a modder and want to use it as the basis of a derivative mod, please feel free to do so. I ask only that you let me know about it.

The Ludeon forums discussion thread for my mods can be found here[ludeon.com].

If you have any (helpful) suggestions for improvement, please let me know!

My mods are free, but if you’d like to buy me a Dr Pepper[ko-fi.com], I wouldn’t complain.

  • Water in ice sheet biomes probably shouldn’t freeze, or should just freeze solid into generic ice; I’ll look at changing that. And nothing can be build on ice frozen over water by design, because that ice will soon thaw back to water again, but you’re right, it would make sense to still be able to build bridges over it.As to your ‘treat permafrost like ice sheet,’ though, to be honest, I created the permafrost biome specifically as an alternative that would have ground ice NOT subject to the new ‘hard mode’ rules in ‘Fertile Fields.’ Ice in ice sheets is, per the description (and per the real life regions the biome is based upon), kilometers thick. There’s really no way to get rid of it to expose any different terrain. Ice in permafrost biomes is much thinner, and *can* be removed to expose underlying terrain. (That’s also why permafrost biomes, unlike ice sheet biomes, aren’t completely ice covered, but feature both ice and soil.)
  • I’m trying to farm some pine trees but they die in the winter due to ‘rotting’. I don’t think I’m running any other mods that alter temperature behavior, it just looks like the game arbitrarily kills the trees after some length of time with no growth progress, the way crops kept in the dark will die. I’m OK with that because I found the term I was looking for, krummholz: https://en.wikipedia.org/wiki/Krummholz It’s a permafrost/tundra adapted tree, and the game doesn’t really have such a thing. I suggest you add it, it would fit with this mod ๐Ÿ™‚
  • Ice that forms on water is custom terrain, so other mods shouldn’t affect it. Water becomes thin ice, then thick ice, as it freezes, and then melts back to whichever type of water it was originally as the temperature rises. However, ground ice that advances and retreats in permafrost biomes is vanilla ice — ‘Ice, Ice, Baby!’ (I had to go there) — and so could be affected by other mods.As to how this mod handles ground ice changes, it’s not perfect, but it works. Ice only spreads over soil, stony soil or marshy terrain tiles. (It won’t spread over stone, marsh or water.) When it retreats, it leaves behind stony soil, regardless of what the terrain was originally. I did that because there’s no easy way to keep track of what a tile was before ice replaced its original terrain. But the bulk of non-ice terrain in permafrost biomes is stony soil, anyway, and given that ice advances and retreats slowly, I doubt it’s something that would call attention to itself.
  • Hmm. I hadn’t specifically thought about the implications of using this mod in conjunction with ‘Archipelagos’ on a lake map…. But, yeah, what you described is exactly what I’d have expected to happen. And honestly, I’m not sure how I’d ‘fix’ it even if I thought it needed to be fixed. :D(Ocean water on maps doesn’t freeze, simply because, for a variety of reasons, oceans in reality typically don’t freeze. But even large lakes can freeze, and there’s really no easy way — and no particularly compelling reason — to try to keep larger lakes in the game from doing so. Though I might try to add in a check to make larger lakes freeze more slowly, to simulate the fact that they hold heat better than smaller ones.)
  • Some behavior that isn’t really consistent (maybe bug, maybe not):- Pools of water in Ice Sheet biomes freeze as they would in Permafrost biomes, I guess this is probably not a bug but fyi.- map start generated ice patches in Permafrost (i.e. NOT pools of water that have frozen) can be removed with Fertile Fields/Terraform/Remove Ice even when Hard Mode is enabled (this is probably a bug)Apparently nothing at all can be built on pools of water that have frozen over – this makes sense I suppose in maps that have a range of temperature that can permit them to thaw again, but in ice sheet biomes where the temperature is permanently below freezing, it feels weird. I don’t know what to suggest aside from like, permit building bridges so you can at least build support for other things like furniture and walls if you really want to.
  • I have to say, I downloaded your realistic planets mod some time ago to mess with the new settings. After playing on a permafrost tile for a good while, I came back to check what other mods you had, and saw this.’Wow, he has a mod to improve permafrost too?’What I didn’t know is that this was supposed to /add/ the biome to the game (which is added /with/ your realistic planets mod), it fit so smoothly with the game’s biomes that I thought the biome was vanilla this whole time.Goes to say a lot about the quality of your mods, love them to bits.Keep up the good work!
