IsActivePublisher() - Encore

Calls onChange with the current state of an Entitlement, then again on each change, until you dispose the handle it returns. Follows changes on iOS only: on Android and WebGL it calls onChange(false) once.

Signature

public static IDisposable IsActivePublisher(Entitlement entitlement, EntitlementScope scope, Action<bool> onChange)
public static IDisposable IsActivePublisher(Entitlement entitlement, Action<bool> onChange)   // EntitlementScope.All

Parameters

Name	Type	Default	Description
`entitlement`	`Entitlement`	required	The entitlement to follow
`scope`	`EntitlementScope`	`All`	Which grants count
`onChange`	`Action<bool>`	required	Called with the current state, then on each change

Example

using System;
using EncoreKit;
using UnityEngine;

public class PremiumBadge : MonoBehaviour
{
    [SerializeField] private GameObject badge;
    private IDisposable _subscription;

    private void OnEnable() =>
        _subscription = Encore.IsActivePublisher(Entitlement.FreeTrial(), active => badge.SetActive(active));

    private void OnDisable() => _subscription?.Dispose();
}

Notes

onChange runs on the Unity main thread, and never after you dispose the handle.
Before Configure(), or when the native subscribe fails before any answer, it calls onChange(false) once.
Throws ArgumentNullException when entitlement or onChange is null.
