TSW Live & Historical Weather

NOW OPEN SOURCE: https://github.com/vanlueckn/TSW5Mods

This mod introduces live weather synchronization and historical weather to Train Sim World 5.

The mod queries the current position on the map and uses the API from open-meteo.com to retrieve the current weather data based on the position. While driving, the weather is updated every 5 minutes (15 minutes is the shortest interval for weather updates from the API, but changing coordinates while driving make a shorter interval useful).

If you select Live Weather, the weather will reflect the current real-life conditions, regardless of the date or time used in the simulator. The second mode is Historical Weather. In this mode, the mod queries the weather based on your selected date and time in the simulator. If you select the historical weather mode and choose a future date, the mod queries the weather based on the current or last year. The month, day, and time will remain the same.

The API may be used free of charge for non-commercial purposes. There is a limit of 10,000 API requests per day, but this should not be exhausted by this mod.

Please install the dependency (UE4SS) before installing this mod.

Important: This is a beta release of the mod. If you have any problems or suggestions for improvement, please use the comment function.

How to use

After installing, you will find two new options in the weather settings menu. Choose Live Weather or Historical Weather instead of Dynamic Weather or Custom Weather to activate the mod for your journey. After starting, the first synchronization will occur after ~60 seconds.

If you are in historical mode and change the date using the God Mode mod or time-related console commands, the mod will force a weather synchronization.

Known issues

• Sometimes the game crashes after the journey
• After starting a journey, it takes up to 60 seconds for the weather to synchronize.
• At the beginning there is no snow on the ground and it only appears gradually. I will adjust this with historical data in the future.

Roadmap

• Add possibility to keep irl time in sync
• Add more realistic sunset and sunrise behaviour
