With Unity 2022.2 I am having a weird offset for ExtendObject properties. Any ideas?

Same problem for Serializable classes used as members of the extended object. I think foldout in general is the issue.

That sounds to me on first impression to be caused by Unity's switch to UI toolkit default editors. See if the problem is gone when changing the setting "Project Settings/Editor/Use IMGUI Default Inspector" to true. I believe UI Toolkit might not properly set EditorGUIUtility.hierarchyMode to true in its PropertyField code.

Is there a way I can exclude a specific type of ScriptableObject from being drawn with this?

@robrab2000 Yup, see ignoreClassFullNames

Thanks! It doesn't seem to be fixing the issue I'm having however. I'm using OdinInspector to create window which has buttons and does stuff. I want to be able to assign a custom scriptable object in the window but it seems to be struggling to find the type. When it renders the editor window I get loads of errors: NullReferenceException: Object reference not set to an instance of an object ExtendedScriptableObjectDrawer.GetFieldType () (at Assets/Scripts/SO-Scripts/Editor/ExtendedScriptableObjectDrawer.cs:271)

Line 271 is:
Type GetFieldType () { Type type = fieldInfo.FieldType;

The GetFieldType() function necessarily gets called before checking against the ignoreClassFullNames list. Perhaps the issue is with Odin though...

Huh. fieldInfo is a property in PropertyDrawer, so that should be set before OnGUI is called. What object are you inspecting?

I'm drawing a custom scriptable object within an OdinEditorWindow

Here is the window shown with the ExtendedScriptableObjectDrawer disabled and then enabled

This is such a great tool. Thank you!

I've been getting Unity editor crashes in this case:

• My ScriptableObject type (call it MySOType) contains a List
• I create a cyclical reference using this list: A -> B -> A

I've done some digging through the code to try to prevent it by statically tracking some state but I haven't been able to prevent the crash. Any thoughts?

I believe this can be fixed by adding lines similar to these, taken from my own modified script so some changes are probably necessary:

public static uint maxDepth = 5;

public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
{
    depth++;
    try
    {
        float totalHeight = EditorGUIUtility.singleLineHeight;
        var so = property.objectReferenceValue as ScriptableObject;
        if (depth > maxDepth || so == null)
            return totalHeight;

        //...
    }
    finally
    {
        depth--;
    }
}

public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
    depth++;
    try
    {
        label = EditorGUI.BeginProperty(position, label, property);

        var type = GetFieldType();


        // Ignoring
        if (depth > maxDepth || type == null
            || ignoreClassFullNames.Contains(type.FullName)
            || Attribute.IsDefined(fieldInfo, typeof(NonExtendedScriptableObjectAttribute)))
        {
            property.isExpanded = false; // Just in case
            DoObjectField(position, property, label, type);
            //EditorGUI.PropertyField(position, property, label);
            EditorGUI.EndProperty();
            return;
        }

        //...

Super helpful! Thanks! If anyone can confirm this works we can merge it in; I've not got the time to do it just now. Ta!

Thank you for saving my day! (probably more than a day actually :D)

I'm not sure about the codes, but I have move to UIToolkit. It's less codes to write editor and easy to implement.

Added a small code change so it won't trype to create ScriptableObjects of abstract class

                if (!type.IsAbstract && GUI.Button(buttonRect, "Create"))

Actually took it a step further,

Made a Property Attribute

    public class ExtendableScriptableObject : PropertyAttribute
    {
        public Type createType;


        public ExtendableScriptableObject()
        {
        }

        public ExtendableScriptableObject(Type createType)
        {
            this.createType = createType;
        }
    }

And then edited the create function

else if (!type.IsAbstract || propertyAttribute.createType != null)
           {
               if (GUI.Button(buttonRect, "Create"))
               {
                   string selectedAssetPath = "Assets";
                   if (property.serializedObject.targetObject is MonoBehaviour)
                   {
                       MonoScript ms =
                           MonoScript.FromMonoBehaviour((MonoBehaviour)property.serializedObject.targetObject);
                       selectedAssetPath = System.IO.Path.GetDirectoryName(AssetDatabase.GetAssetPath(ms));
                   }

                   var typeToCreate = type;
                   if (propertyAttribute.createType != null)
                   {
                       typeToCreate = propertyAttribute.createType;
                   }

                   property.objectReferenceValue = CreateAssetWithSavePrompt(typeToCreate, selectedAssetPath);
               }
           }

And now I can use it like this: (RecoludeAPIRecordingResolver extends RecordingResolverConfig)

        [ExtendableScriptableObject(typeof(RecoludeAPIRecordingResolver))] [SerializeField]
        private RecordingResolverConfig resolverConfig;

Hi, love this. Not a specialist of prop drawer in unity.
Updating to latest Odin in my main project started to have errors resulting in wrangled layout in inspector of a gameobject with Scriptables.

After a bit of digging (and again I don't know what Im doing in Prop Drawers ;-)
I had to add a test in this function so that it does not break/stops when encountering refs to scriptables objects that are not referencing any (basically null pointers to SO in the MonoBehaviour)

Type GetFieldType () {
		// FIX NICO ? IF NULL then dont try to get type
		if (fieldInfo == null)
		{
			return null;
		}
		Type type = fieldInfo.FieldType;
		if(type.IsArray) type = type.GetElementType();
		else if (type.IsGenericType && type.GetGenericTypeDefinition() == typeof(List<>)) type = type.GetGenericArguments()[0];
		return type;
	}

Does it make sense ?
Thanks a lot for this.
Nick

If you end up with a Type Mismatch in your inspector, this script will spam invalid cast warnings at this line in AreAnySubPropertiesVisible:
var data = (ScriptableObject)property.objectReferenceValue;

Does anyone know of a simple way to guard against this?

Isn't there a bug in AreAnySubPropertiesVisible(), as if it returns early it fails to dispose the serializedObject?

This could be solved by replacing the 'return true' statement with setting a found property and break, but I figured going with a 'using' would be better. Additionally I add a guard around data being null.
Anyone see anything wrong with this?

   static bool AreAnySubPropertiesVisible(SerializedProperty property)
    {
        var data = ( ScriptableObject )property.objectReferenceValue;

        if ( null != data )
        {
            using ( SerializedObject serializedObject = new SerializedObject(data) )
            {
                SerializedProperty prop = serializedObject.GetIterator();

                // Check for any visible property excluding m_script
                while ( prop.NextVisible(true) )
                {
                    if ( prop.name == "m_Script" )
                        continue;

                    return true;
                }
            }
        }

        return false;
    }

Going further I'm wondering if all instances of getting a SerializedObject in the script should be wrapped in 'using' to ensure dispose is automatically called even if an exception occurs.

Finally i'm not entirely convinced for the need for 'AreAnySubPropertiesVisible', as in best case it returns quickly as most properties are going to be visible, but by the same token i'm not sure there is a worse case as how could a scriptableObject have every property non-visible.

At this point I realized I don't fully understand what the 'visible' property explicitly denotes as I've never given it much thought. The documentation isn't much help, but appears to suggest that HideInInspector, isExpanded and hasVisibileChildren can only affect this value. However the only one of those that truly doesn't draw anything at all would be HideInInspector,. This suggests to me the possibility that there is nothing to draw at all ( once past the explicit isExpanded check for our scriptableObject reference we already have ) is low to non-existent. Therefore is this method pointless?

Edit: Just wondering what the point is of the '_GUILayout' methods and associated 'DrawScriptableObjectField/DrawScriptableObjectFields'? They aren't currently used as far as I can tell and its not exactly clear where one might have used it. Checked the previous revisions and found where they were added, though again they don't appeared to be used, nor is there any comments as to why they were added. Would it not be better to remove them?

Isn't there a bug in AreAnySubPropertiesVisible(), as if it returns early it fails to dispose the serializedObject?

This could be solved by replacing the 'return true' statement with setting a found property and break, but I figured going with a 'using' would be better. Additionally I add a guard around data being null. Anyone see anything wrong with this?

   static bool AreAnySubPropertiesVisible(SerializedProperty property)
    {
        var data = ( ScriptableObject )property.objectReferenceValue;

        if ( null != data )
        {
            using ( SerializedObject serializedObject = new SerializedObject(data) )
            {
                SerializedProperty prop = serializedObject.GetIterator();

                // Check for any visible property excluding m_script
                while ( prop.NextVisible(true) )
                {
                    if ( prop.name == "m_Script" )
                        continue;

                    return true;
                }
            }
        }

        return false;
    }

Good spot, sounds sensible. I'll swap to using statements locally and update this if I don't run into any problems.
On the visible property - I can't really recall how this works and I don't have time to run tests. Let me know if you work it out!
The GUILayout functions were duplicates of DrawScriptableObjectField. Oops! Fixed.

if (fieldInfo == null)

Totally does, I've added this to the script :)

Hello.

I have a problem with your script and https://github.com/ayellowpaper/SerializedDictionary
If there is a SerializedDictionary in the SO, then after Expand I get the following error in this method (their SerializedDictionaryInstanceDrawer class):
NullReferenceException: SerializedObject of SerializedProperty has been Disposed.

public float GetPropertyHeight(GUIContent label)
{
    if (!ListProperty.isExpanded) // error here 
        return SerializedDictionaryDrawer.TopHeaderClipHeight;

    return ReorderableList.GetHeight();
}

Do you have any ideas? Thanks

Hm I just changed how objects are disposed last week. If you try an earlier version of this gist and it works could you let me know?

Thank you for the quick response. I’ve already tried both older and newer versions. Unfortunately, it didn’t help.
Could you possibly check this on your side?

The reproduction steps are very simple:

1. Import SerializedDictionary.
2. Create a ScriptableObject with the following field:

   [SerializedDictionary("Id", "Description")]
   public SerializedDictionary<int, string> ElementDescriptions;

3. Create a field with this ScriptableObject in another MonoBehaviour script and click "Expand" for this SO.

Hm I don't have time to dig into this, sorry! I would try not discarding the serialized objects in this class and seeing if that makes any difference, but if not it sounds like it could be a problem with how the SerializiedDictionary drawer works?
