4. Editor Extension Development

// ✅ Production-Ready: Batch Asset Processor
public class BatchAssetProcessor : EditorWindow
{
    [MenuItem("Tools/Batch Asset Processor")]
    public static void ShowWindow() => GetWindow<BatchAssetProcessor>();

    private void OnGUI()
    {
        if (GUILayout.Button("Apply to All Textures"))
            ApplyToAllTextures();
    }

    private void ApplyToAllTextures()
    {
        var guids = AssetDatabase.FindAssets("t:Texture2D", new[] { "Assets" });
        try
        {
            AssetDatabase.StartAssetEditing();
            for (int i = 0; i < guids.Length; i++)
            {
                var path = AssetDatabase.GUIDToAssetPath(guids[i]);
                var importer = AssetImporter.GetAtPath(path) as TextureImporter;
                if (importer == null) continue;

                EditorUtility.DisplayProgressBar("Processing", path, (float)i / guids.Length);
                // Apply settings...
                importer.SaveAndReimport();
            }
        }
        finally
        {
            AssetDatabase.StopAssetEditing();
            EditorUtility.ClearProgressBar();
        }
    }
}

🔧 Troubleshooting Guide

┌─────────────────────────────────────────────────────────────┐
│ PROBLEM: Build times too long                                │
├─────────────────────────────────────────────────────────────┤
│ DEBUG: Measure stages, check cache hit rate, profile import │
├─────────────────────────────────────────────────────────────┤
│ SOLUTIONS:                                                   │
│ → Enable Library folder caching                             │
│ → Parallelize independent build targets                     │
│ → Use faster runners (self-hosted with SSDs)               │
└─────────────────────────────────────────────────────────────┘

┌─────────────────────────────────────────────────────────────┐
│ PROBLEM: Import errors / Missing references                  │

├─────────────────────────────────────────────────────────────┤
│ SOLUTIONS:                                                   │
│ → Delete Library folder, reimport                           │
│ → Lock package versions in manifest                         │
│ → Regenerate missing .meta files                            │

Recovery Procedures

Failure Mode	Detection	Recovery Action
CI broken	Pipeline fails	Revert, fix forward
Asset corruption	Import errors	Restore from VCS
Cache stale	Wrong output	Clear cache, rebuild
