Function savePrefab

src/world/saver.ts:40–54

(path: string, prefab: PrefabData)

// Write a prefab file. Same semantics as `saveWorld` but for prefabs.
export function savePrefab(path: string, prefab: PrefabData): SaveResult {
  prefab.schemaVersion = WORLD_SCHEMA_VERSION;

  const check = validatePrefab(prefab);
  if (!check.ok) {
    return { ok: false, errors: check.errors };
  }

  const json = JSON.stringify(prefab, null, 2);
  const ok = writeFile(path, json);
  if (!ok) {
    return { ok: false, errors: ['writeFile failed for path: ' + path] };
  }
  return { ok: true, errors: [] };
}

// Convenience: format a SaveResult's errors as a single human-readable string.
// The editor uses this for status bar / dialog messages.
