DrawPropertiesExluding for non Monobehaviour classes?

Having an error trying to assign classAbilities from target under OnInspectorGUI(). Error is cannot convert ClassAbilities to UnityEngine.Object. I realize it's because ClassAbilities doesn't inherit Monobehaviour, but I haven't been able to find a solution for this.

Code (CSharp):

1. [CustomEditor(typeof(ClassAbilities))]
2. public class ClassAbilitiesEditor : Editor
3. {
4.     public override void OnInspectorGUI()
5.     {
6.         ClassAbilities classAbilities = target as ClassAbilities;
7.         List<string> excludedProperties = new List<string>();
8.  
9.         if (!classAbilities.CanUse)
10.             excludedProperties.Add("_abilities");
11.  
12.         if (excludedProperties.Count > 0)
13.             DrawPropertiesExcluding(serializedObject, excludedProperties.ToArray());
14.         else
15.             DrawDefaultInspector();
16.  
17.         ProcessChanges(classAbilities);
18.     }
19. }

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3.  
4. namespace FirstGearGames.MOBAROyale.Abilities
5. {
6.     [System.Serializable]
7.     public class ClassAbilities
8.     {
9.         /// <summary>
10.         /// Use CanUse.
11.         /// </summary>
12.         [Tooltip("True if the unit can use this weapon in the specified HandPlacements.")]
13.         [SerializeField]
14.         private bool _canUse = true;
15.         /// <summary>
16.         /// True if the unit can use this weapon in the specified HandPlacements.
17.         /// </summary>
18.         public bool CanUse { get { return _canUse; } }
19.         /// <summary>
20.         /// Use Abilities.
21.         /// </summary>
22.         [Tooltip("Abilities for the UnitClass using this weapon.")]
23.         [SerializeField]
24.         private List<Ability> _abilities = new List<Ability>();
25.         /// <summary>
26.         /// Abilities for the UnitClass using this weapon.
27.         /// </summary>
28.         public List<Ability> Abilities { get { return _abilities; } }
29.     }
30.  
31.  
32. }

 

As non-MonoBehaviour/SO classes aren't ever given an editor of their own, having an editor class for one doesn't make much sense. If your ClassAbilities class is meant to be a property in another SO or MonoBehaviour, you want to use a PropertyDrawer instead.

 

This was helpful, thank you.
