Reply To: SerializeReference doesn’t work in custom task

Hello again,

I just created a Property Drawer which when used on a field, it will popup a selection of the field type implementations and create an instance of that selection. If you want to try it now please do the following:

1) Open up DrawerAttributes.cs and add this code somewhere within the namespace:

1 2 3 4

[AttributeUsage(AttributeTargets.Field)]     public class ReferenceFieldAttribute : DrawerAttribute { }

2) Open up AttributeDrawers.cs and add this code somewhere within the namespace as well:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

public class ReferenceFieldDrawer : AttributeDrawer<ReferenceFieldAttribute>     {         public override object OnGUI(GUIContent content, object instance)         {             var options = ReflectionTools.GetImplementationsOf(fieldInfo.FieldType);             var selection = EditorUtils.Popup<System.Type>(content, instance != null? instance.GetType() : fieldInfo.FieldType, options);             if (selection == null){ return instance = null; }               if (instance == null || instance.GetType() != selection ) {                 if (!typeof(UnityEngine.Object).IsAssignableFrom(selection)){                     return System.Activator.CreateInstance(selection);                 }             }             EditorGUI.indentLevel++;             EditorUtils.ReflectedObjectInspector(instance, contextUnityObject);             EditorGUI.indentLevel--;             return instance;         }     }

You can then use the [ReferenceField] attribute on your custom task interface type fields.
Please let me know how this works for you.

Thank you.
