PointerEventData.pointerDrag

説明

The object that is receiving OnDrag.

Calling pointerDrag returns the GameObject this script is attached to. This is a ScrollView.

The parent of the pointerDrag can be set to null. This prevents OnDrag and OnEndDrag from being called.

// OnDrag() has the pointerDrag GameObject removed.
// This stops the cursor being moved.

public class ExampleScript : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler

    private float timeCount;

    public void OnBeginDrag(PointerEventData data)

        Debug.Log("OnBeginDrag: " + data.position);
        data.pointerDrag = null;
    }

    public void OnDrag(PointerEventData data)
    {
        if (data.dragging)
        {
            timeCount += Time.deltaTime;
            if (timeCount > 1.0f)
