// Set m_Item2 to point to the same object as m_Item // Note: managedReferenceValue could also be used here, for the same result item2Property.managedReferenceId = itemProperty.managedReferenceId;

serializedObject.ApplyModifiedProperties(); }

// Check the results back on the live object

//Will print "Value of m_Item2.m_data: 1" Debug.Log("Value of m_Item2.m_data: " + scriptableObject.m_Item2.m_data);

// Prove that both fields point to the same object scriptableObject.m_Item.m_data = 2;

//Will print "Value of m_Item2.m_data: 2" Debug.Log("Value of m_Item2.m_data: " + scriptableObject.m_Item2.m_data); } }
