Version Notes

2.0.0 version changes:

  • Moved the mod to C# / SPT 4.0
  • Instead of switching the season every 7 days, added lengths for each one. Winter and summer are slightly less than 2 weeks while offseasons (autumn, autumn_late, spring, spring_early) are about 7 days as previously.
  • Setting some season’s length to 0 will result in ignoring this season

A very simple mod that automatically changes seasons.

  • When first installed, the timer starts on the day of the first run.
  • The first season will be whichever season comes next after your current one. For example, if you play vanilla SPT without season-changing mods and your current season is summer, the mod will switch to early autumn, then to late autumn, then to winter and so on
  • In 2.0.0 (SPT 4.0) version, default setting is ~7 days for offseasons and ~14 days for winter and summer, you can change it in the config. The SPT 3.11 version is 7 days for each season.
  • Not compatible with other season-changing mods (and not intended to be)
  • Runs only when SPT server starts - so no season change in-game in edge cases

This mod is meant to be simple. If you need more flexebility, you should probably use some of these mods:
Tarkov Weather System

Time & Weather Changer NG
Simple Season Selector

TLDR: Added weather variety to spring and autumn.

Details: It turns out transitional seasons (all varieties of spring and autumn) don’t have proper weather values in the vanilla SPT server config, raids are basically sunny almost all the time - huge thanks to markopas for the report. I added more (grumpy) weather variety to the transitional seasons, though it might need some tweaking in the future. You can disable these changes and switch back to vanilla weather in the config, or just download version 1.0.0 if you want sun.

Just out of curiosity would the mod work just fine if you changed line 199 in SeasonsRotator.cs from public Dictionary<Season, int> SeasonsLengths { get; set; } = new();

to

public Dictionary<Season, double> SeasonsLengths { get; set; } = new();

So that we could use decimal points? This would allow for rotations measured in hours as I believe DateTime.AddDays() can accept a double. Also feel free to call me dumb as I am not the best with all this type of stuff.

I built it with said change and its not throwing any errors and looks to be working correctly.

Makes sense, but the state is still saved as yyyy-mm-dd :) I guess not many players really need floats and seasons changes mid-day, at least this mod wasn’t intended for it.

And I’d never call anyone who is curious and willing to learn “dumb”. Feel absolutely free to experiment as much as you want, whether it’s just to adjust it for yourself or make a new mod.

Just to be clear, season changes don’t even happen mid-game in this mod, they occur only when server starts. Initially I wrote this mod (TS version) in 20-30 minutes just for myself, and tbh I’m not interested in making it more advanced. There were more complex weather/season mods for SPT 3.x, and I’m pretty sure some of them will move to SPT 4.x too eventually.

Fair enough I geuss I didnt pay attention to the fact that it only changes the season on server start XD

is there a way to force a season to be the start of the rotation like starting on winter? or would i be able to force a season using SVM or another mod and then this mod would start to rotate after the set number of days?

The easiest to do it, I think, is:

  1. Run the game with mod installed for the first time, so it generates state.json file
  2. go to mod folder, open state.json
  3. Change “CurrentSeason” number to the number of season you need

Seasons numbers: SUMMER = 0, AUTUMN = 1, WINTER = 2, SPRING = 3, AUTUMN_LATE = 4, SPRING_EARLY = 5

so let’s say the mod settled autumn as the current season. in this case it would be 1. and if you want it to change to summer you change 1 to 0.

probably a much better way to do it lol, way i did it was i changed all seasons except winter to be 1 minute long, and winter to be 8 months long

not possible via config, but you can open src/mod.ts and

find this line

constseasonsArray= [0, 1, 4, 2, 5, 3]

change it to

constseasonsArray= [0, 1, 4, 5, 3]

make sure you don’t have winter enabled currently. delete state.json in mod folder if so

Why is it always sunny even tho its autumn?
No rain or no clouds so there is no sun

idk, it doesn’t change weather, at least it should not - it only rewrites 1 config variable that is responsible for season

i encourage you to try other mods (links in description) if you want to have some control over weather

Hmmm sad. Idea is very nice its just sad that im getting one weather and that’s it.

It seems transitional seasons (everything except summer and winter) don’t have proper values by default, so if you force a season even without my mod it will be the same

I will add weather variety to the mod, hopefully soon
