Unity/R3/UniRxから移植

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));

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

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();

ReactiveCollectionをObservableList<T>へ

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

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

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