Unity TimeLine扩展
发表于2018-10-26
这篇内容给大家介绍下TimeLine的扩展使用，例如说想在TimeLine中右键添加自定义的Track，具体的步骤如下：
1、创建一个继承于TrackAsset的脚本
using UnityEngine; using UnityEngine.Timeline; [TrackColor(0.855f, 0.903f, 0.87f)] // 添加的具体资源类型 [TrackClipType(typeof(NewPlayableAsset))] // 绑定指定类型 //[TrackBindingType(typeof(GameObject))] public class CustomTrack : TrackAsset ｛ ｝
2、创建PlayableAsset类
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Playables;
using UnityEngine.Timeline;
[System.Serializable]
public class NewPlayableAsset : PlayableAsset,ITimelineClipAsset
｛
public ExposedReference<GameObject> obj;
// 使其暴露在面板中，但是该类需要序列化
public NewPlayableBehaviour np = new NewPlayableBehaviour();
public ClipCaps clipCaps
｛
get ｛ return ClipCaps.None; ｝
｝
// Factory method that generates a playable based on this asset
public override Playable CreatePlayable(PlayableGraph graph, GameObject go) ｛
np.Obj = obj.Resolve(graph.GetResolver());
return ScriptPlayable<NewPlayableBehaviour>.Create(graph, np);
//return Playable.Create(graph);
｝
｝
3、具体功能的实现
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Playables;
using UnityEngine.Timeline;
using System;
// 如果不序列化，在面板中没办法看到参数接口
[Serializable]
public class NewPlayableBehaviour : PlayableBehaviour
｛
private GameObject obj;
public string str;
public GameObject Obj
｛
get
｛
return obj;
｝
set
｛
obj = value;
｝
｝
// Called when the owning graph starts playing
public override void OnGraphStart(Playable playable) ｛
｝
// Called when the owning graph stops playing
public override void OnGraphStop(Playable playable) ｛
｝
// Called when the state of the playable is set to Play
public override void OnBehaviourPlay(Playable playable, FrameData info) ｛
｝
// Called when the state of the playable is set to Paused
public override void OnBehaviourPause(Playable playable, FrameData info) ｛
｝
// Called each frame while the state is set to Play
public override void PrepareFrame(Playable playable, FrameData info) ｛
Debug.Log(Obj.name);
｝
｝
