[CustomEditor] Displaying an array in a struct list like the default inspector

I am trying to display an array in a custom inspector the way the default inspector displays it.
That array is contained in a serialized struct, which i have a list of.

Here is where i am so far :


Test script :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Test : MonoBehaviour {
6.  
7.     public List<TheStruct> theStructList = new List<TheStruct>();
8.  
9.     [System.Serializable]
10.     public struct TheStruct
11.     {      
12.         public float[] theFloatArray;      
13.     }
14. }

CustomEditor script :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [CustomEditor(typeof(Test))]
7. public class TestEditor : Editor {
8.  
9.     Test test;
10.  
11.     public override void OnInspectorGUI()
12.     {
13.         serializedObject.Update();
14.  
15.         foreach (Test.TheStruct myStruct in test.theStructList)
16.         {
17.             SerializedObject so = new SerializedObject((Object) myStruct);
18.  
19.             SerializedProperty sp = so.FindProperty("theFloatArray");
20.  
21.             EditorGUILayout.PropertyField(sp, true);
22.         }
23.      
24.         serializedObject.ApplyModifiedProperties();
25.     }
26.  
27.     void OnEnable()
28.     {
29.         test = target as Test;      
30.     }
31. }

The problem i have currently is that i can't access the properties of the struct element from the foreach loop because the struct element cannot be converted into an Object

Is there any way to make this work ?

Thanks

 

[SerializeField]
public float[] theFloatArray;

Looking for that to see the array ??

 

It doesn't hurt to add it, but the issue is line 17 where i try to cast myStruct to an Object, it cannot be converted that way.

But thank you anyway.

 

So, small update on my issue, i managed to display the array, but any change i make is instantly reverted to the old value, any idea how to fix that ?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [CustomEditor(typeof(Test))]
7. public class TestEditor : Editor {
8.  
9.     Test test;
10.  
11.     public override void OnInspectorGUI()
12.     {
13.         serializedObject.Update();
14.         base.DrawDefaultInspector();
15.  
16.         GUILayout.Label("----------------------Test----------------------");
17.        
18.         SerializedObject so = new SerializedObject(target);      
19.         SerializedProperty listsp = so.FindProperty("theStructList");
20.  
21.         for (int i = 0; i < test.theStructList.Count; i++)
22.         {
23.             SerializedProperty arraysp = listsp.GetArrayElementAtIndex(i).FindPropertyRelative("theFloatArray");
24.             EditorGUI.BeginChangeCheck();          
25.  
26.             EditorGUILayout.PropertyField(arraysp, true);
27.          
28.             if (EditorGUI.EndChangeCheck())
29.             {              
30.                 serializedObject.ApplyModifiedProperties();
31.             }
32.         }    
33.     }
34.  
35.     void OnEnable()
36.     {
37.         test = target as Test;      
38.     }
39. }

 

That's because you're making a new SerializedObject, but applying the modified properties to the one from Editor.

Code (csharp):

1. SerializedObject so = new SerializedObject(target);  
2. ...
3.  
4. if (EditorGUI.EndChangeCheck())
5. {
6.     serializedObject.ApplyModifiedProperties(); //this should be so, not serializedObject
7. }

In fact, you don't need to create so at all, serializedObject is the same thing.

 

Thanks, it's working perfectly now
