Custom PropertyDrawer is not called

Hello,

I don't understand why my custom PropertyDrawer is not called from my custom Editor.

Here my property declaration :

Code (CSharp):

1. [SerializeField]
2.     private List<SpellEffect>    _spellsEffects;

Here how the propertyDrawer is called in my custom Editor :

Code (CSharp):

1. // --- SpellsEffects ---
2.         Debug.Log("Call property drawer");
3.         SerializedProperty se = this.serializedObject.FindProperty("_spellsEffects"); // I checked in debug mod : everything is OK at this point.
4.         EditorGUILayout.PropertyField(se, true);

Here my propertyDrawer definition :

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEditorInternal;
4. using System.Collections.Generic;
5.  
6. [CustomPropertyDrawer(typeof(List<SpellEffect>))]
7. public class Drawer_object : PropertyDrawer {
8.     //_____ CONSTRUCTOR _________________________________________________________
9.     public Drawer_object () : base() {
10.         Debug.Log("Init PropertyDrawer");
11.     }
12.  
13.     ~Drawer_object () {
14.         Debug.Log("Destructor PropertyDrawer");
15.     }
16.  
17.     //_____ TRIGGER _____________________________________________________________
18.     public override void OnGUI (Rect position, SerializedProperty property, GUIContent label) {
19.         Debug.Log("ON GUI PropertyDrawer");
20.     }
21. }

Here my consol log :


As you can see the PropertyDrawer is never called. Do you have an idea why ?

Thanks for your help.

 

I think it should be [CustomPropertyDrawer(typeof(SpellEffect))].
Property drawers for list fields are not done on the list property itself, it's one property drawer call per each list element.
Also make sure SpellEffect has System.Serializable attribute

 

Hello,

Thanks for your reply. It looks like you are true : https://forum.unity.com/threads/pro...-inspector-customization.150337/#post-1031443
It's an old post but we can't do propertyDrawer for List or Array themself.

A solution could be to wrap the list inside a custom classe, but the downside is that this class won't be serialized as an array/List by unity.
Thanks for your help, i have to find an other way to do that.
