[NodeCanvas] Helper to find possible null references in BB

[leanon00]

Hello! Made this tool to help me find possible null references in the blackboards of my NC tree assets.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52

public class NC_GraphAssetsInspector : EditorWindow     {         private List<Graph> graphAssets = new List<Graph>();           [MenuItem("Tools/NC Types Inspector")]         public static void ShowWindow()         {             GetWindow<NC_GraphAssetsInspector>("NC Types Inspector");         }           private void OnGUI()         {             if (GUILayout.Button("Find and Print Graph Scriptable Objects"))             {                 FindAndPrintGraphAssets();             }               EditorGUILayout.Space();               foreach (var item in graphAssets)             {                 EditorGUILayout.ObjectField(item, typeof(Graph), true);             }         }           private void FindAndPrintGraphAssets()         {             string[] assetGuids = AssetDatabase.FindAssets("t:" + nameof(Graph));             graphAssets.Clear();               foreach (string assetGuid in assetGuids)             {                 string assetPath = AssetDatabase.GUIDToAssetPath(assetGuid);                 Graph graph = AssetDatabase.LoadAssetAtPath<Graph>(assetPath);                   if (graph != null)                 {                     foreach (var item in graph.blackboard.variables.Values)                     {                         if (item.varType == typeof(object))                         {                             Debug.LogWarning(item + " from: " + graph.name + " detected as possible null Type with type: " + item.varType, context: graph);                             graphAssets.Add(graph);                         }                     }                 }             }         }                }
