在unity中，有这么一些接口
IPointerClickHandler, IPointerEnterHandler, IPointerExitHandler, IPointerMoveHandler, IPointerUpHandler, IPointerDownHandler, IInitializePotentialDragHandler, IBeginDragHandler, IDragHandler, IEndDragHandler, IDropHandler, IScrollHandler, IUpdateSelectedHandler, ISelectHandler, IDeselectHandler, IMoveHandler, ISubmitHandler, ICancelHandler这些接口可以响应一些触摸事件，一般这些是ui控件挂载一个实现了这些接口的脚本就可以响应的，现在想让场景中的3d物体也能响应这些事件该怎么做呢？
一.创建3d物体，并挂载实现了这些接口的脚本
public class Supported : MonoBehaviour, IPointerClickHandler, IPointerEnterHandler, IPointerExitHandler, IPointerMoveHandler, IPointerUpHandler, IPointerDownHandler, IInitializePotentialDragHandler, IBeginDragHandler, IDragHandler, IEndDragHandler, IDropHandler, IScrollHandler, IUpdateSelectedHandler, ISelectHandler, IDeselectHandler, IMoveHandler, ISubmitHandler, ICancelHandler
{
public void OnBeginDrag(PointerEventData eventData)
{
Debug.Log("OnBeginDrag");
}
public void OnCancel(BaseEventData eventData)
{
Debug.Log("OnCancel");
}
public void OnDeselect(BaseEventData eventData)
{
Debug.Log("OnDeselect");
}
public void OnDrag(PointerEventData eventData)
{
Debug.Log("OnDrag");
}
public void OnDrop(PointerEventData eventData)
{
Debug.Log("OnDrop");
}
}二.创建EventSystem
三.camera挂载Graphic Raycaster 和 Physics Raycaster
运行游戏，鼠标放在物体上就能触发OnPosinterMove等事件
