[HideReferenceObjectPicker] Doesn't seems to affect nested dictionaries.

[Ruslan Kudriachenko]

Here is the code sample that causing the issue at the moment:

[CreateAssetMenu]
[HideMonoScript]
public class SinglePlayerLevelSettings : SerializedScriptableObject
{
    [System.Serializable]
    [InlineProperty]
    public struct WordsCountSetting
    {
        [OdinSerialize]
        [HideLabel]
        [HorizontalGroup]
        [MinValue(0)]
        public int MinCount { get; private set; }

        [OdinSerialize]
        [HideLabel]
        [HorizontalGroup]
        [MinValue(0)]
        public int MaxCount { get; private set; }
    }

    [System.Serializable]
    [InlineProperty]
    public class LevelInfo
    {
        [OdinSerialize]
        [HideReferenceObjectPicker]
        [DictionaryDrawerSettings(DisplayMode = DictionaryDisplayOptions.OneLine, KeyLabel = "Letters count", ValueLabel = "Words count")]
        private Dictionary<int, WordsCountSetting> wordsSettings = new Dictionary<int, WordsCountSetting>();
    }

    [OdinSerialize]
    [HideReferenceObjectPicker]
    [DictionaryDrawerSettings(DisplayMode = DictionaryDisplayOptions.OneLine, KeyLabel = "Initial level", ValueLabel = "Settings")]
    private Dictionary<int, LevelInfo> levelsInfo = new Dictionary<int, LevelInfo>();
}

In fact it’s doesn’t seems to affect values of the dictionary in any way.

I’am want to see no reference field for some cases, but I can’t change it in the any way except mentioned below:

I managed to hide parameter by adding the attribute to the class definition:

‌

But I don’t think it’s perfect solution because you might not want to have this at some other place. Is it possible to add something like [HideReferenceValuePicker], [HideReferenceValuePickerIf(“MyFunc”)] attribute or something like that?

This is the challenge of working with dictionaries - there's no straightforward way to "target" attributes at keys or values in the dictionary. What I would suggest is to use an attribute processor to conditionally apply HideReferenceObjectPicker only if you are in a dictionary (for example, the property name is "Value" or the parent is an EditableKeyValuePair or whatever you'd like to distinguish it). You can have a look at our tutorials for attribute processors.
