Unity/UniRx/EventTrigger

サンプル

オブジェクトに、触れたときとか、外れたときとかのイベントを取得できる。 ObservableEventTriggerを、オブジェクトに、事前にAddComponentしておいても良い。

using UniRx.Triggers;

GameObject eventTextObj = GameObject.Find("EventText");
var eventTrigger = eventTextObj.AddComponent<ObservableEventTrigger>();
        
eventTrigger.OnPointerEnterAsObservable()
            .Subscribe(pointerEventData => Debug.Log("PointerEnter " + pointerEventData.position)); // 触れた時 PointerExit (666.0, 1013.0)
eventTrigger.OnPointerExitAsObservable()
            .Subscribe(pointerEventData => Debug.Log("PointerExit " + pointerEventData.position)); // 外れた時
eventTrigger.OnDragAsObservable()
            .Subscribe(pointerEventData => Debug.Log("Drag " + pointerEventData.position));
eventTrigger.OnPointerDownAsObservable()
            .Subscribe(pointerEventData => Debug.Log("PointerDown " + pointerEventData.position)); // downした時
eventTrigger.OnPointerClickAsObservable()
            .Subscribe(pointerEventData => Debug.Log("PointerClick " + pointerEventData.position)); // upした時だが、PointerUpの後に実行
eventTrigger.OnPointerUpAsObservable()
            .Subscribe(pointerEventData => Debug.Log("PointerUp " + pointerEventData.position)); // upした時
eventTrigger.OnBeginDragAsObservable()
            .Subscribe(pointerEventData => Debug.Log("BeginDrag " + pointerEventData.position));
eventTrigger.OnEndDragAsObservable()
            .Subscribe(pointerEventData => Debug.Log("EndDrag " + pointerEventData.position));
eventTrigger.OnDropAsObservable()
            .Subscribe(pointerEventData => Debug.Log("Drop " + pointerEventData.position)); // EndDragとほぼ同じで、EndDragより早い。
eventTrigger.OnInitializePotentialDragAsObservable()
            .Subscribe(pointerEventData => Debug.Log("Initialize " + pointerEventData.position)); // downした時とほぼ同じで、少し後
eventTrigger.OnScrollAsObservable()
            .Subscribe(pointerEventData => Debug.Log("Scroll " + pointerEventData.position)); // オブジェクト上でscrollした時
// 以下は、反応しない
eventTrigger.OnDeselectAsObservable()
            .Subscribe(baseEventData => Debug.Log("Deselect " + baseEventData.selectedObject));
eventTrigger.OnSelectAsObservable()
            .Subscribe(baseEventData => Debug.Log("Select " + baseEventData.selectedObject));
eventTrigger.OnSubmitAsObservable()
            .Subscribe(baseEventData => Debug.Log("Submit " + baseEventData.selectedObject));
eventTrigger.OnCancelAsObservable()
            .Subscribe(baseEventData => Debug.Log("Cancel " + baseEventData.selectedObject));
eventTrigger.OnUpdateSelectedAsObservable()
            .Subscribe(baseEventData => Debug.Log("UpdateSelected " + baseEventData.selectedObject));
eventTrigger.OnMoveAsObservable()
            .Subscribe(axisEventData => Debug.Log("Move " + axisEventData.moveVector));
