Development Notes

Adding New Effects

1. Create new effect function following the pattern:

const newEffect = () => {
  setTimeout(() => {
    // Hydra effect code here
    .out();
  }, 100);
};

2. Add to hydraEffects array
3. Update terminal command switch statement
4. Add to help text

Hydra Syntax Tips

• Use scrollX() and scrollY() for positioning (not translate())
• Use shape(32, ...) for smooth circles (not shape(4, ...))
• Always end effect chains with .out()
• Use setTimeout() wrapper for stability

Troubleshooting

Common Issues

1. Effects not loading: Check browser WebGL support
2. Audio not playing: Check CORS and network connectivity
3. Mobile controls not working: Ensure touch events are enabled
4. Terminal not responding: Check for JavaScript errors in console

Browser Requirements

• WebGL support for Hydra effects
• Modern ES6+ JavaScript support
• Audio API support for music playback
• Local storage for playlist history
