// Example showing the structure of SerializedProperty objects that comprise an Array property exposed by SerializedObject. // Often this structure can be ignored and SerializedProperty.arraySize and SerializedProperty.GetArrayElementAtIndex(0) // are convenient to jump straight to the size and data content. // But, because the specific structure is exposed when using SerializedProperty.Next and SerializedProperty.propertyPath, // some understanding of this structure can be useful. public class StructureOfArrayExample : ScriptableObject { // Serialized array // Note: The example would behave the same way if it was List<int> public string[] m_Data;

StructureOfArrayExample obj = ScriptableObject.CreateInstance<StructureOfArrayExample>(); obj.m_Data = new string[] { "zero", "one" };
SerializedObject serializedObject = new SerializedObject(obj);
// Top level property represents the entire array SerializedProperty serializedProperty = serializedObject.FindProperty("m_Data"); ReportPropertyDetails(serializedProperty, log);
// Next element is a structural element ".Array". // This does not take any space in the serialized data, and acts much the same as the top level property bool visitChildren = true; serializedProperty.Next(visitChildren); ReportPropertyDetails(serializedProperty, log);
// First nested child is ".Array.size", which stores the number of elements of the array serializedProperty.Next(visitChildren); ReportPropertyDetails(serializedProperty, log);
// Next comes the first array element, ".Array.data[0]". // In this case it is the string "zero". Strings are also represented as Arrays in SerializedObject. serializedProperty.Next(visitChildren); ReportPropertyDetails(serializedProperty, log);
// Skip past the nested content of the first string to get to the next string ("one") visitChildren = false; serializedProperty.Next(visitChildren); ReportPropertyDetails(serializedProperty, log);
//Will log: //Property path: 'm_Data' type: 'Generic' isArray: True depth: 0 //Property path: 'm_Data.Array' type: 'Generic' isArray: True depth: 0 //Property path: 'm_Data.Array.size' type: 'ArraySize' isArray: False depth: 1 //Property path: 'm_Data.Array.data[0]' type: 'String' isArray: True depth: 1 //Property path: 'm_Data.Array.data[1]' type: 'String' isArray: True depth: 1 Debug.Log(log.ToString()); }
