🎧 Sound Effects

Place your ambient sound files inside /audio/bgs/ folder:

Weather TypeExpected BGS File
Rain or Drizzle Rain.ogg
Thunderstorm Thunder.ogg

If the weather clears, the background sound will automatically stop.

🖼️ Time-Based Tinting

Automatically adjusts screen tint based on the current local time of your target city:

Time (Hour)Tint Applied
5:00–8:59 Dawn tint
9:00–16:59 Day (no tint)
17:00–19:59 Sunset tint
20:00–4:59 Night tint


🧠 How It Works

  1. The plugin connects to the OpenWeatherMap API using your API key and city.

  2. It fetches the current weather + timezone offset.

  3. Based on this:

    • RPG Maker’s weather is applied ($gameScreen.changeWeather)

    • Time tint is adjusted using $gameScreen.startTint

    • Corresponding BGS is played via AudioManager.playBgs

✅ Installation

  1. Download and include the RealWeather.js plugin in your /js/plugins/ folder.

  2. Add it to your Plugin Manager.

  3. Fill in:

    • Your OpenWeatherMap API Key

    • City of your choice

    • Set Update on Load to true or false depending on your needs

  4. Add appropriate sound files to /audio/bgs/ folder.

💬 Example Use Case

Want your snowy RPG to actually snow when it's snowing in Tokyo? Just set "Tokyo" as your city and watch your maps dynamically match the real weather, time, and even mood.

🧪 Plugin Command Example

Use in an event:

Plugin Command: UpdateWeather

This will refresh and re-apply real-world weather data on demand.

💡 Tips

  • Use a free or paid OpenWeatherMap account depending on your update frequency needs.

  • Combine with parallax overlays or region-based effects for next-level immersion.

  • Check the console (F8) for debug logs if the weather fails to load.
