UniRxでDOTweenをObservableにする

Last updated at Posted at 2019-02-02

概要

DOTweenをObservableにしました。
すべてのアニメーションの完了を待ってから何かしたいといった場合に、
Observable化されていると、何かと便利です。

DOTween

無料版と有料版があり、それぞれアセットストアからDLできます。
DOTween (HOTween v2)
DOTweenPro

使用バージョン

DOTweenPro v1.0.075

コード

DOTweenExtensions.cs
using UniRx;
using System;
using DG.Tweening;

static public partial class DOTweenExtensions
{
    static public IObservable<Tween> OnCompleteAsObservable(this Tween tweener)
    {
        return Observable.Create<Tween>(o =>
        {
            tweener.OnComplete(() =>
            {
                o.OnNext(tweener);
                o.OnCompleted();
            });
            return Disposable.Create(() =>
            {
                tweener.Kill();
            });
        });
    }

    static public IObservable<Sequence> PlayAsObservable(this Sequence sequence)
    {
        return Observable.Create<Sequence>(o =>

#endif //DOTweenPro Extensions
}

DOTweenProでのみ使用可能なDOTweenAnimationを使用しているコードは
if~endifで囲っています。無料版を使用している場合はDOTweenAnimationが使用不可なので、
falseにしてください。

使用例

DOLocalMove

        this.transform.DOLocalMove(new Vector3(-200f, 0f, 0f), 1f)
            .OnCompleteAsObservable()
            .Subscribe(_ => 
            {
                Debug.Log("Completed.");
            })
            .AddTo(this);

シーケンス


        // シーケンス
        var sequence = DOTween.Sequence();
        sequence.Append(anim.tween);
        sequence.PlayAsObservable().Subscribe(_ =>
        {
            Debug.Log("Complete Sequence.");
        })
        .AddTo(this);

Observable.WhenAllですべてのアニメの待機完了待ち


    [SerializeField] DOTweenAnimation[] animations;

    void Start()
    {
        Observable.WhenAll(animations.Select(x => x.DOPlayAsObservable(rewind)))
        .Subscribe(x =>
        {
            Debug.Log("Completed.");
        });
        .AddTo(this);
    }

AsyncMessageBrokerでアニメの待機完了待ち

他にもMessageBrokerの非同期版であるAsyncMessageBrokerで、
送り手がメッセージをPublishして誰がReceiveしているかわからないけど完了するまで
送り手を待機させるといった、疎結合な非同期処理も可能です。

    public class AnimEvent {}

    // 受け手
    public class SampleReceiver : MonoBehaviour
    {
        [SerializeField] DOTweenAnimation anim;

        void Awake()
        {
            AsyncMessageBroker.Default.Subscribe<AnimEvent>(_ =>
                bool rewind = true;
                anim.DOPlayByIdAsObservable("in", rewind)
            ).AddTo(this);
        }
    }

    // 送り手
    public class SamplePublisher : MonoBehaviour
    {
        void Start()
        {
            AsyncMessageBroker.Default.PublishAsync<AnimEvent>(new AnimEvent()).Subscribe(_ =>
            {
                Debug.Log("Publish Completed.");
            });
        }
    }
