EditorApplication.hierarchyWindowChanged

Descripción

A callback to be raised when an object in the hierarchy changes.

Each time an object is (or a group of objects are) created, renamed, parented, unparented or destroyed this callback is raised.

See Also: EditorWindow.OnHierarchyChange.

using UnityEditor;
using UnityEngine;

public class ExampleCode
{
    [MenuItem("Example/Hierarchy Window Changed")]
    static void Example()
    {
        EditorApplication.hierarchyWindowChanged += ExampleCallback;
    }

    static void ExampleCallback()
    {
        Object[] all = Resources.FindObjectsOfTypeAll(typeof(Object));
        Debug.Log("There are " + all.Length + " objects at the moment.");
    }
}

Note: Changing the HideFlags on an object will also cause this callback to be called.
