🎵 AudioReactor for Flax Engine

Real-time audio visualization for Flax Engine. This plugin analyzes audio frequencies using NAudio and syncs your game world (lights, cameras, UI, objects) to the beat.

✨ Features

• Plug & Play: Just drag it in, no C# knowledge required.
• Auto-Sync: Handles the complex math to sync game time with audio time.
• The "Safe House": Automatically manages raw .wav files in a MusicData folder so Flax doesn't corrupt them.
• Modular Reactors: Different scripts for different needs (Camera, UI, Objects, Lights).

📦 File Structure

Ensure your files are arranged like this: AudioReactor/ ├── AudioReactor.flaxproj ├── README.md └── Source/ ├── NAudio.dll ├── AudioReactorPlugin.cs ├── AudioReactor.Build.cs ├── RealTimePulse.cs (Lights & Materials) ├── AudioCameraReactor.cs (FOV, Sway, Shake) ├── AudioTransformReactor.cs (Scale, Spin, Jitter) └── AudioUIReactor.cs (UI Punch, Color)

🚀 How to Use

1. Setup

1. Drag the AudioReactor folder into your project's Plugins/ folder.
2. Open your project. The plugin will activate automatically.
3. Drag a .wav file into your Content window.
   • The plugin will silently copy a raw version to MusicData/ for analysis.
