using置換

- using UniRx;
+ using R3;
- using UniRx.Triggers;
+ using R3.Triggers;
- using System;

ObserveEveryValueChangedはEveryValueChangedへ

// UniRx
transform.ObserveEveryValueChanged(_ => _.Count).Subscribe(count => Debug.Log(count))
    .AddTo(gameObject);

// R3
CompositeDisposable disposable;
disposable = new CompositeDisposable();
Observable.EveryValueChanged(transform, _ => _.Count)
    .Subscribe(count => Debug.Log(count))
    .AddTo(disposable);

Observable.Createの置換

// UniRx
IObservable<int> isCompletedsAsObservable = Observable.Create<int>(observer =>
            {
                return Disposable.Empty;
            });
// R3
Observable<int> isCompletedsAsObservable = Observable.Create<int>(observer =>
            {
                return Disposable.Empty;
            });

IObservableをObservableへ

// UniRx
ObservableCollision2DTrigger landTrigger;
IObservable<Collision2D> landOnCollisionEnterAsObservable = landTrigger.OnCollisionEnter2DAsObservable();

// R3
ObservableCollision2DTrigger landTrigger;
Observable<Collision2D> landOnCollisionEnterAsObservable = landTrigger.OnCollisionEnter2DAsObservable();

Observable.EveryUpdate()~AddTo()の返り値まわり対応

//UniRx
var observable = Observable.EveryUpdate()
.Subscribe(_ => {
            }).AddTo(disposable);

// R3
Observable.EveryUpdate()
.Subscribe(_ => {
    // 略
            }).AddTo(disposable);

ReactiveCollectionをObservableList<T>へ

ObservableList では、`using ObservableCollections;`を追加する。

// UniRx
private ReactiveCollection<string> users = new ReactiveCollection<string>();
users
    .ObserveAdd()
    .Subscribe(value =>
    {
        Debug.Log($"[Add]Index={value.Index},Value={value.Value}");
    });

// R3
using ObservableCollections;
private ObservableList<string> users = new ObservableList<string>();
users
    .ObserveAdd()
    .Subscribe(value =>
    {
        Debug.Log($"[Add]Index={value.Index},Value={value.Value}");
    });

SubjectのSubscribeの置換

// UniRx
Subject<string> subject = new Subject<string>();
subject
    .Subscribe(
        message => Debug.Log("msg1:" + message),
        error => Debug.LogError("Error" + error)
        () => Debug.Log("Completed")
            );

// R3
Subject<string> subject = new Subject<string>();
subject
    .Subscribe(
        message => Debug.Log("msg1:" + message),
        error => Debug.LogError("Error" + error)
            );

TakeUntilDestroyはAddTo()へ置換

// UniRx
button.OnClickAsObservable()
    .TakeUntilDestroy(gameObject)
    .Subscribe(_ => {
        Debug.Log("click!");
    });

// R3
button.OnClickAsObservable()
    .Subscribe(_ => {
        Debug.Log("click!");
    })
    .AddTo(gameObject);
