[游戏开发]Unity Timeline的资产动态创建内容动态编辑添加

也是冷不丁的要做这块的东西.翻博客翻了半天也没有非常一文解决我需求的.整理好了就自己写个以备不时之需? ,也分享给其他需要的人

先上干货:

创建Timeline资产

_timelineAsset = ScriptableObject.CreateInstance<TimelineAsset>();

资产上创建一条条的内容

var track = _timelineAsset.CreateTrack<ActivationTrack>(null, "Track1");
var track1 = _timelineAsset.CreateTrack<AnimationTrack>(null, "TrackAnimator");

设置单条的clip内容

var clip = track.CreateDefaultClip();
clip.start = 2;
clip.duration = 2f;

再上运行后效果

最后是完整代码

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Playables;
using UnityEngine.Timeline;

public class Wd : WDParent
{
   public GameObject bingdi1;
   public GameObject bingdi2;
   
   private PlayableDirector _playabledirector;   
   private TimelineAsset _timelineAsset;
   Dictionary<string, PlayableBinding> bindingDict = new Dictionary<string, PlayableBinding>();

   public override void Start()
   { 
      _timelineAsset = ScriptableObject.CreateInstance<TimelineAsset>();
      _playabledirector = gameObject.AddComponent<PlayableDirector>();
      AddTrack();
      _playabledirector.playableAsset = _timelineAsset;
      foreach (var bind in _playabledirector.playableAsset.outputs)
      {
         if (!bindingDict.ContainsKey(bind.streamName))
         {
            bindingDict.Add(bind.streamName, bind);
         }
      }

      SetTrackDynamic("Track1", bingdi1);
      SetTrackDynamic("Track2", bingdi2);

   }
   //根据名称设置绑定的物体
   public void SetTrackDynamic(string trackName, GameObject gameObject)
   {
      if (bindingDict.TryGetValue(trackName, out PlayableBinding pb))
      {
         _playabledirector.SetGenericBinding(pb.sourceObject, gameObject);
      }
   }
   /// <summary>
   /// 添加时间轨
   /// </summary>
   private void AddTrack()
   {
      //创建timeline一条一条的滑轨条
      var track = _timelineAsset.CreateTrack<ActivationTrack>(null, "Track1");
      var track1 = _timelineAsset.CreateTrack<AnimationTrack>(null, "TrackAnimator");
      var track2 = _timelineAsset.CreateTrack<ActivationTrack>(null, "Track2");
      //设置时间轨道上的clips 设置开始时间和持续时间 end是只读的不可以直接设置
      var clip = track.CreateDefaultClip();
      clip.start = 2;
      clip.duration = 2f;
      //连续添加
      clip = track.CreateDefaultClip();
      clip.start = 8;
      clip.duration = 2;
   }
}
