Unity editor become very slow if reorder List has large struct and large array elements.

Unity editor is very slow if reorder List has large struct and large array elements.

I also noticed the same thing when these structs and array elements contain ScriptableObjects.

Here are several tests I've done:

1. ScriptableObject containing classes which contain ScriptableObject fields will lag if both #LIST_ALL_ARRAYS and #EDIT_ALL_SCRIPTABLES are uncommented
2. ScriptableObject containing classes which contain ScriptableObject fields will not lag if only #LIST_ALL_ARRAYS is uncommented

I've also noticed that if a ScriptableObject contains classes which contain ScriptableObjects, the classes' ScriptableObjects are not editable.

Solution
I made a new PropertyAttribute called NonEditScriptableProperty and added the new header into any child ScriptableObject fields of a ScriptableObject

public class NonEditScriptableAttribute : PropertyAttribute { }

And edited this in ReorderableArrayInspector.cs starting from line 367:

#if EDIT_ALL_SCRIPTABLES
    bool makeEditable = !iterProp.HasAttribute<NonEditScriptableAttribute>();
#else
    bool makeEditable = iterProp.HasAttribute<EditScriptableAttribute>();
#endif

The logic in play here is to set makeEditable to false if a field has the NonEditScriptable attribute. Add this attribute to any inner ScriptableObjects and you should notice that the lag is gone. I have not tested on large Lists of ScriptableObjects.

Example:

[SubjectNerd.Utilities.NonEditScriptable]
[Tooltip("A un-editable ScriptableObject")]
public MyScriptableObject myScriptableObject;

Hope this helps! @LoS-Light @ChemiKhazi
