Editor Reorderable List - Properties

Questions & Answers
1

Hello,

I’m trying to build a very simple Reorderable List of type GameObject, but I can’t get my head around it, in my script of MonoBehaviour, I have a list:

public List<GameObject> MyGameObjects = new List<GameObject>();

And within my Editor script (typeof above script):

private ReorderableList _list;

private void OnEnable() {
		_list = new ReorderableList(
		serializedObject, 
		serializedObject.FindProperty("MyGameObjects"), 
		true, true, true, true);

        _list.drawElementCallback = (Rect rect, 
		int index, 
		bool isActive, 
		bool isFocused) => {
		var element = _list.serializedProperty.GetArrayElementAtIndex(index);

		EditorGUI.PropertyField(new Rect(rect.x, 
			rect.y, 60, EditorGUIUtility.singleLineHeight),

			element.FindPropertyRelative("GameObject"));
	};
	}

The problem lies within ‘FindPropertyRelative’ I believe. This gives me the error: Object reference not set to an instance of an object?

Thanks.

Yes I’m not sure what you’re trying to do, but it should just be element and not element.FindPropertyRelative(“GameObject”)
