是否有可能使 RactiveProperty public 在 UniRx 中获得私有集

Question

我有两个 class。其中之一具有 BoolReactiveProperty。我希望第二个 class 只能订阅而不能更改值。这是我当前的代码

public class SourceToggle : MonoBehaviour
{
    public BoolReactiveProperty boolRP { get; private set; } 
        = new BoolReactiveProperty();

    private void Start()
    {
        boolRP.Subscribe(b => GetComponent<Toggle>().isOn = b);

        GetComponent<Toggle>()
            .OnValueChangedAsObservable()
            .Subscribe(b => boolRP.SetValueAndForceNotify(b));
    }
}

public class SubscribedToggle : MonoBehaviour
{
    [SerializeField]
    private SourceToggle sourceToggle;

    private void Start()
    {
        sourceToggle.boolRP
            .Subscribe(b => GetComponent<Toggle>().isOn = b);

        GetComponent<Toggle>()
            .OnValueChangedAsObservable()
            .Subscribe(b => sourceToggle.boolRP.SetValueAndForceNotify(b));
    }
}

Answer 1

我不完全明白你想阻止什么。我想你想阻止你的 SubscribedToggle 在你的 ReactiveProperty 上调用 SetValueAndForceNotify？

然后在您的 SourceToggle class.

中声明一个 public IReadOnlyReactiveProperty 并管理一个私有 BoolReactiveProperty

public class SourceToggle : MonoBehaviour
{
    private BoolReactiveProperty isOn;
    private Toggle toggle;

    public IReadOnlyReactiveProperty<bool> IsOn => isOn;

    private void Awake()
    {
        toggle = GetComponent<Toggle>();

        isOn = new BoolReactiveProperty(toggle.isOn);

        toggle
            .OnValueChangedAsObservable()
            .Subscribe(b => isOn.SetValueAndForceNotify(b));

        isOn.Subscribe(b => toggle.isOn = b);
    }
}

public class SubscribedToggle : MonoBehaviour
{
    [SerializeField]
    private SourceToggle sourceToggle;

    private void Start()
    {
        sourceToggle.IsOn
            .Subscribe(b => GetComponent<Toggle>().isOn = b);

        // GetComponent<Toggle>()
        //     .OnValueChangedAsObservable()
        //     .Subscribe(b => sourceToggle.IsOn.SetValueAndForceNotify(b)); // Impossible to call SetValueAndForceNotify
    }
}

感谢@Hellium，我找到了解决方案

public class SourceToggle : MonoBehaviour
{
    public ReadOnlyReactiveProperty<bool> IsOn { get; private set; }

    private void Awake()
    {
        Toggle toggle = GetComponent<Toggle>();

        IsOn = new ReadOnlyReactiveProperty<bool>(toggle.OnValueChangedAsObservable());
    }
}

public class SubscribedToggle : MonoBehaviour
{
    [SerializeField]
    private SourceToggle sourceToggle;

    private void Start()
    {
        Toggle toggle = GetComponent<Toggle>();

        sourceToggle.IsOn
            .Subscribe(b => toggle.isOn = b);
    }
}

是否有可能使 RactiveProperty public 在 UniRx 中获得私有集

Is it possible to make RactiveProperty public get private set in UniRx
