Help with Structs and Custom Inspector

Question

Currently trying to build a custom inspector, and I've hit a bit of a wall. Haven't had much experience with Unity, so bear with me if this seems easily obvious.

I have a given struct:

     public AttackProfileInfo[] attackProfiles;
      
     [Serializable]
     public struct AttackProfileInfo
     {
         public float animationDuration;
         public HitProfile hitProfile;
         public float initialDamage;
     }

And I am not sure how to get the relevant information to display in a custom inspector. I tried using SerializedObject/SerializedProperty with no success.

     SerializedObject profiles;
     SerializedProperty animationDuration;
      
     profiles = new SerializedObject(PlayableCharacters.AttackProfileInfo);
     animationDuration = profiles.FindProperty("animationDuration");
     EditorGUILayout.PropertyField(animationDuration);

new SerializedObject isn't working. "PlayableCharacters.AttackProfileInfo is a type, which is not valid in the given context".

Any guidance on where I'm going wrong here would be muchly appreciated. Thanks in advance.

After some time, I have figured out the answer I was looking for. Turns out making this is an array added a bit more of the complexity.

First step, is to search out the original variable name, so in this case:

 var attackProfileArray = serializedObject.FindProperty("attackProfiles");

From there, I set a simple indexer variable for looping:

 int indexer = 0;

Then you can use a combination of GetArrayElementAtIndex with FindPropertyRelative, which gets the field in the struct, so:

 hitProfileArray.GetArrayElementAtIndex(indexer).FindPropertyRelative("animationDuration").floatValue = EditorGUILayout.FloatField("Animation Duration", PlayableCharacters.attackProfiles[indexer].animationDuration);
 hitProfileArray.GetArrayElementAtIndex(indexer).FindPropertyRelative("hitProfile").objectReferenceValue = (HitProfile)EditorGUILayout.ObjectField("HitProfile", PlayableCharacters.attackProfiles[indexer].hitProfile, typeof(HitProfile), true);

Which is all put into a loop, so it can be iterated. The loop is surrounded with BeginChangeCheck() and EndChangeCheck()).

If changes are detected with EndChangeCheck(), then serializedObject.ApplyModifiedProperties() is called.

Try to use a class instead of a struct, in Unity i have never used struct, also to make a custom inspector you need a script with the editorBehviour and set which script you want to set custom.

Thanks for the reply. Unfortunately, I cannot change how the structs have been created. This is also only a sample of the code since this is part of a larger editor script.

Usually, with this kind of things i make a for an inside it putfor every custom variable inside the structure i made Edit: Ex: for(int i=0;i
