Using UnityEvent to execute arbitrary code from Unity timelines.
Inspiration reference: https://github.com/georgejecook/UnityTimelineEvents
I replace the former methods with UnityEvent. I bind UnityEvent and TimelineClip on custom script to store UnityEvent just like PlayableDirector do.
It can even work on same scene, same timeline but different director.
Create TimelineUnityEventTrack in Timeline
Add TimelineUnityEventClip. Then it will create a binding script on your director object.
Select clip and set UnityEvent.
The binding script is bound on director.
