Caution

Deprecated. Use OnValueChanged instead.

Important

Enable SaintsEditor before using

OnValueChanged can not detect if an array/list is changed in size. OnArraySizeChanged attribute will call a callback for that.

Using it together with OnValueChanged to get all changing notification for an array/list.

Parameters:

• string callback: the callback function when the size changed.
• Allow Multiple: No

using SaintsField;  // namespace for OnValueChanged
using SaintsField.Playa;  // namespace for OnArraySizeChanged

[Serializable]
public class MyClass  // generic class change is also detectable
{
    public string unique;
}

[OnValueChanged(nameof(ValueChanged))]  // optional
[OnArraySizeChanged(nameof(SizeChanged))]
public MyClass[] myClasses;

public void ValueChanged(MyClass myClass, int index) => Debug.Log(
quot;OnValueChanged: {myClass.unique} at {index}");

// if you do not care about values, just omit the parameters
public void SizeChanged(IReadOnlyList<MyClass> myClassNewValues) => Debug.Log(
quot;OnArraySizeChanged {myClassNewValues.Count}: {string.Join("; ", myClassNewValues.Select(each => each?.unique))}");
