Unity TimeLine循环播放某个时间段

1、设置Playable Director的Update Method为GameTime模式

2、API : using UnityEngine.Playables;
我们需要用到PlayableDirector的time属性

3、设置开始和结束时间段（使用的帧率）我在0-158帧循环和158到290帧之间循环

4、代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Playables;
using System;
public class ModlesManager : MonoBehaviour
{
    public GameObject m_Book;//PlayableDirector 组件的载体
    public List<TimeScopes> m_TimeScopes = new List<TimeScopes>();//设置时间段
    private PlayableDirector m_BookAndLight;
    private bool m_IsCanPlay;//是否播放timeline
    void Start()
    {
        m_BookAndLight = m_Book.GetComponent<PlayableDirector>();
    }
    public void SetIsCanPlay(bool ison)
    {
        m_IsCanPlay = ison;
    }
    private void PlayTimeline()
    {
        if (m_IsCanPlay)
        {
            m_BookAndLight.time += Time.deltaTime;
            //加30是为了在争取在循环的时候能最贴合动画时间，可以自己测试自己动画时间
            if(m_BookAndLight.time>= Getfps(m_TimeScopes[1].m_TimeStart+30))
            {
               
            }
            if (m_BookAndLight.time >= Getfps(m_TimeScopes[m_TimeScopeindex].m_TimeEnd))
            {
                if (m_TimeScopes[m_TimeScopeindex].m_IsLoop)
                {
                    m_BookAndLight.time = Getfps(m_TimeScopes[m_TimeScopeindex].m_TimeStart);                 
                }else
                {
                    m_BookAndLight.Pause();
                    m_IsCanPlay = false;
                }                        
            }
        }
    }
        /// <summary>
    /// 计算当前帧率 动画为每秒60帧
    /// </summary>
    /// <param name="targetfps"></param>
    /// <returns></returns>
     private double Getfps(double targetfps)
    {
        return targetfps / 60;
    }
}
[Serializable]
public class TimeScopes
{
    public double m_TimeStart;
    public double m_TimeEnd;
    public bool m_IsLoop;
}
