Building Music-Reactive Bullet Hell with Unity DOTS
Project Overview
HARMONIC BARRAGE is a music-reactive bullet hell shooting game inspired by Space Invaders Infinity Gene and Beat Saber. It captures system audio (Spotify, YouTube, etc.) in real-time and "visualizes" music through FFT analysis to generate bullet patterns.
Key Specifications
- Bullet Patterns: 32 types (fully implemented)
- Performance: 100,000 bullets @ 144fps
- Tech Stack: Unity 6 + DOTS + WASAPI + NAudio
- Implementation: 11,303 lines of code (Phase 1-3 complete)
1. Unity DOTS Architecture
Traditional GameObject/MonoBehaviour cannot handle 100,000 simultaneous bullets. DOTS uses data-oriented design to maximize CPU cache usage, accelerate with Burst Compiler, and achieve parallel processing with Job System.
Conclusion
By combining Unity DOTS and WASAPI, we achieved an innovative shooting game that generates bullet patterns from real-time music analysis.
Key Achievements
- ✅ 32 bullet patterns fully implemented
- ✅ 100,000 bullets @ 144fps achieved
- ✅ Real-time system audio capture
- ✅ FFT analysis for frequency band extraction
- ✅ 11,303 lines of implementation code
