挂载在UI上的脚本：
using UnityEngine;
using DG.Tweening;
using UnityEngine.EventSystems;
/// <summary>
/// 此脚本挂载在UI上,鼠标在UI上滑动时旋转指定对象
/// </summary>
public class UITouchRotateTarget : MonoBehaviour, IDragHandler
{
/// <summary>
/// 要旋转的对象
/// </summary>
public Transform target = null;
/// <summary>
/// 旋转速度(3-5效果最佳)
/// </summary>
public float speed = 5.0f;
//DOTween过渡时间(为1时效果最佳)
private float m_time = 1.0f;
//缓存Vector3,避免频繁New
private Vector3 m_rot = Vector3.zero;
public void OnDrag(PointerEventData eventData)
{
if (target == null) return;
float y = eventData.delta.x;
m_rot.y = -y * speed;
target.DOLocalRotate(m_rot, m_time, RotateMode.LocalAxisAdd).SetEase(Ease.OutCubic);
}
}
