Showcase An editor window to show you prefab properties

I get confused when working with prefabs, so I made an editor window to show you prefab properties. It doesn't cover the whole PrefabUtility API (modifications and arrays are notably absent), but useful for when you're trying to figure out which function returns True in the right cases.



See the gist for more elegance, but the code is essentially this:

Code (CSharp):

1. using UnityEditor.Experimental.SceneManagement;
2. using UnityEditor.SceneManagement;
3. using UnityEditor;
4. using UnityEngine;
5. public class PrefabDetector : EditorWindow {
6.     [MenuItem("Tools/PrefabDetector")]
7.     static void ShowToolbar() {
8.         EditorWindow.GetWindow<PrefabDetector>("PrefabDetector");
9.     }
10.     public void OnGUI() {
11.         var go = Selection.activeGameObject;
12.         EditorGUIUtility.labelWidth = 300;
13.         EditorGUILayout.ObjectField("Selection", go, typeof(GameObject), allowSceneObjects: true);
14.         EditorGUILayout.Space();
15.         EditorGUILayout.LabelField("PrefabStageUtility", EditorStyles.boldLabel);
16.         var stage = PrefabStageUtility.GetCurrentPrefabStage();
17.         EditorGUILayout.LabelField("GetCurrentPrefabStage", stage != null ? "has stage" : "null");
18.         if (stage != null) {
19.             EditorGUILayout.LabelField("IsPartOfPrefabContents", "" + stage.IsPartOfPrefabContents(go));
20.         }
21.         EditorGUILayout.Space();
22.         EditorGUILayout.LabelField("PrefabUtility", EditorStyles.boldLabel);
23.         EditorGUILayout.LabelField("IsAddedComponentOverride", "" + PrefabUtility.IsAddedComponentOverride(go));
24.         EditorGUILayout.LabelField("IsAddedGameObjectOverride", "" + PrefabUtility.IsAddedGameObjectOverride(go));
25.         EditorGUILayout.LabelField("IsAnyPrefabInstanceRoot", "" + PrefabUtility.IsAnyPrefabInstanceRoot(go));
26.         EditorGUILayout.LabelField("IsDisconnectedFromPrefabAsset", "" + PrefabUtility.IsDisconnectedFromPrefabAsset(go));
27.         EditorGUILayout.LabelField("IsOutermostPrefabInstanceRoot", "" + PrefabUtility.IsOutermostPrefabInstanceRoot(go));
28.         EditorGUILayout.LabelField("IsPartOfAnyPrefab", "" + PrefabUtility.IsPartOfAnyPrefab(go));
29.         EditorGUILayout.LabelField("IsPartOfImmutablePrefab", "" + PrefabUtility.IsPartOfImmutablePrefab(go));
30.         EditorGUILayout.LabelField("IsPartOfModelPrefab", "" + PrefabUtility.IsPartOfModelPrefab(go));
31.         EditorGUILayout.LabelField("IsPartOfNonAssetPrefabInstance", "" + PrefabUtility.IsPartOfNonAssetPrefabInstance(go));
32.         EditorGUILayout.LabelField("IsPartOfPrefabAsset", "" + PrefabUtility.IsPartOfPrefabAsset(go));
33.         EditorGUILayout.LabelField("IsPartOfPrefabInstance", "" + PrefabUtility.IsPartOfPrefabInstance(go));
34.         EditorGUILayout.LabelField("IsPartOfPrefabThatCanBeAppliedTo", "" + PrefabUtility.IsPartOfPrefabThatCanBeAppliedTo(go));
35.         EditorGUILayout.LabelField("IsPartOfRegularPrefab", "" + PrefabUtility.IsPartOfRegularPrefab(go));
36.         EditorGUILayout.LabelField("IsPartOfVariantPrefab", "" + PrefabUtility.IsPartOfVariantPrefab(go));
37.         EditorGUILayout.LabelField("IsPrefabAssetMissing", "" + PrefabUtility.IsPrefabAssetMissing(go));
38.         EditorGUILayout.ObjectField("GetCorrespondingObjectFromOriginalSource", PrefabUtility.GetCorrespondingObjectFromOriginalSource(go), typeof(GameObject), allowSceneObjects: true);
39.         EditorGUILayout.ObjectField("GetCorrespondingObjectFromSource", PrefabUtility.GetCorrespondingObjectFromSource(go), typeof(GameObject), allowSceneObjects: true);
40.         EditorGUILayout.ObjectField("GetIconForGameObject", PrefabUtility.GetIconForGameObject(go), typeof(Texture), allowSceneObjects: true);
41.         EditorGUILayout.ObjectField("GetNearestPrefabInstanceRoot", PrefabUtility.GetNearestPrefabInstanceRoot(go), typeof(GameObject), allowSceneObjects: true);
42.         EditorGUILayout.ObjectField("GetOutermostPrefabInstanceRoot", PrefabUtility.GetOutermostPrefabInstanceRoot(go), typeof(GameObject), allowSceneObjects: true);
43.         EditorGUILayout.TextField("GetPrefabAssetPathOfNearestInstanceRoot", PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot(go));
44.         EditorGUILayout.LabelField("GetPrefabAssetType", PrefabUtility.GetPrefabAssetType(go).ToString());
45.         EditorGUILayout.ObjectField("GetPrefabInstanceHandle", PrefabUtility.GetPrefabInstanceHandle(go), typeof(GameObject), allowSceneObjects: true);
46.         EditorGUILayout.LabelField("GetPrefabInstanceStatus", PrefabUtility.GetPrefabInstanceStatus(go).ToString());
47.     }
48. }
