🚧 In Progress (Next Steps) ​

High Priority ​

  1. Particle System Sync (90% ready)

    • Impact: Real-time particle visualization
    • Effort: ~50 lines

  2. Fragment Visualization (50% ready)

    • Issue: Fracture creates physics fragments but no visual updates
    • Solution: Hook fracture events → renderer.addObject()
    • Impact: Real-time fracture visualization
    • Effort: ~100 lines

  3. Structural Damage Visualization (0% ready)

    • Issue: Structural failures not visualized
    • Solution: Expose structural elements, color-code load
    • Impact: See building collapse progression
    • Effort: ~150 lines

Medium Priority ​

  1. Post-Processing Effects (0% ready)

    • Bloom for explosions
    • Motion blur for fast debris

🔥 Quick Start ​

Execute .holo File (Runtime) ​

typescript
import { RuntimeRegistry } from '@holoscript/core/runtime';
import { ThreeJSRenderer } from '@holoscript/core/runtime';
import '@holoscript/core/demos/demolition';

// Parse composition
const composition = parseHoloScript(holoSource);

// Create renderer
const renderer = new ThreeJSRenderer({
  canvas: document.getElementById('canvas'),
});

// Execute with auto-sync
const executor = RuntimeRegistry.execute(composition, {
  renderer,
  autoSyncRenderer: true,
});

executor.start(); // Physics + rendering!

Export to Unity (Compilation) ​

typescript
import { compileToUnity } from '@holoscript/core/compiler';

const composition = parseHoloScript(holoSource);
const unityCode = compileToUnity(composition);

// Save to file, import into Unity
fs.writeFileSync('DemolitionScene.cs', unityCode);
