PlayableDirector 组件开始播放时所引发的事件。
向此事件添加一个事件处理程序,以便在 PlayableDirector 开始播放时接收相关通知。该处理程序还接收正在播放的 PlayableDirector。
使用 PlayableBehaviour 时,系统将在 PlayableBehaviour.OnPlayableCreate 之后以及 PlayableBehaviour.OnGraphStart 和 PlayableBehaviour.OnBehaviourPlay 之前引发此事件。
如果使用 PlayableDirector.playOnAwake 自动播放 PlayableDirector,则不会引发此事件。
using UnityEngine; using UnityEngine.Playables;
public class PlayableDirectorCallbackExample : MonoBehaviour { public PlayableDirector director;
void OnEnable() { director.played += OnPlayableDirectorPlayed; }
void OnPlayableDirectorPlayed(PlayableDirector aDirector) { if (director == aDirector) Debug.Log("PlayableDirector named " + aDirector.name + " is now playing."); }
void OnDisable() { director.played -= OnPlayableDirectorPlayed; } }
