一、脚本事件运用
Add添加Playable Track轨道，在后面的轨道中右键会有Event System Playable文本显示，点击创建。
代码部分：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Playables;
//Timeline脚本事件运用
public class EventSystemPlayable : PlayableAsset
{
public string eventId;
public string param;
public override Playable CreatePlayable(PlayableGraph graph, GameObject owner)
{
var playable = ScriptPlayable<NewPlayableBehaviour>.Create(graph);
playable.GetBehaviour().eventId = eventId;
playable.GetBehaviour().param = param;
return playable;
}
}
public class NewPlayableBehaviour : PlayableBehaviour
{
public string eventId;
public string param;
public override void OnBehaviourPlay(Playable playable, FrameData info)
{
Debug.Log("发送事件 id ："+ eventId+ "___param :"+ param);
//EventMgr.Instance.SendEvent(eventId, param);
}
public override void PrepareFrame(Playable playable, FrameData info)
{
Debug.Log("触发时每帧都执行");
}
}
运行结果：
