The project requires no environment variables or API keys.
Edit src/server.ts to change port:
const server = Bun.serve({
port: 3000, // Change as needed
// ...
});Edit public/js/main.js to modify default quality:
this.qualitySettings = {
bloom: true,
trails: true,
atmosphere: true,
antialiasing: true,
pixelRatio: Math.min(window.devicePixelRatio, 2)
};Use the theme manager to switch between 7 preset themes or create custom ones:
// Apply a theme
themeManager.applyTheme('nebula');
// Create custom theme
themeManager.addCustomTheme('myTheme', {
name: 'My Theme',
description: 'Custom color scheme',
colors: { /* color definitions */ },
ui: { /* UI settings */ }
});| Issue | Solution |
|---|---|
| Port 3000 in use | Change port in src/server.ts |
| Black screen | Check browser console (F12), verify WebGL support |
| Low FPS | Switch to Low/Medium quality preset |
| Textures not loading | Check public/textures/ folder exists |
| News not loading | Check internet connection, fallback news will display |
| Trails lagging | Reduce maxTrailPoints or disable trails |
| VR not working | Check WebXR support, use HTTPS, verify headset connection |
| Worker errors | Web Workers may not work in some environments, features will fallback |
Verify WebGL support: get.webgl.org
Verify WebXR support: Check browser console for WebXR messages
