using UnityEngine;using System.Collections;using System;//新增命名空间 using UnityEngine.EventSystems;//新增public class DragJoyStick : **//这俩个是新增接口 IDragHandler,IEndDragHandler**MonoBehaviour,IDragHandler,IEndDragHandler {    private Vector3 direction;    public float maxDistance;//可以拖动的最大距离    public void OnDrag(PointerEventData eventData)    {        transform.position = Input.mousePosition;        //鼠标拖动摇杆移动         if (Vector3.Distance(Vector3.zero,transform.localPosition)>maxDistance)        {            direction = transform.localPosition - Vector3.zero;//获取方向            transform.localPosition = direction.normalized * maxDistance;//当超出范围一直在边界        }    }    public void OnEndDrag(PointerEventData eventData)    {        transform.localPosition = Vector3.zero;        //鼠标松开后回到原点    } }

效果如下图所示
