// Bring a scene saved by an older engine up to date, and say what changed.

void main() {
  const saved = '{"version": 5, "name": "cave", "entities": []}';
  final scene = jsonDecode(saved) as Map<String, dynamic>;
  final result = SceneFormat.migrateWithReport(scene);
  print('format v${result.fromVersion} -> v${SceneFormat.current}');
  for (final note in result.notes) {
    print('  $note');
  }

  // A new level, as the editor makes one.
  print(SceneStarters.encode(SceneStarters.twoD('level_02')));
