Description of the program

About Timeline Assets

The Timeline asset (.playable file) played in this sample is set in the PlayableDirector component of the game object "AtomTimeline".
In the Timeline window, you can add and edit CRI Atom tracks and clips.

About playback control

Playback control of Timeline is realized by Assets/Scripts/TimelineControl.cs (sample common script).

/* Code excerpt */
director = GetComponent<PlayableDirector>();

if (Scene_00_GUI.Button(playButtonRect, "Play")) {
    director.Play();
}

if (Scene_00_GUI.Button(pauseButtonRect, "Pause")) {
    director.Pause();
}

if (Scene_00_GUI.Button(stopButtonRect, "Stop")) {
    director.Stop();
}

When paused, playback is resumed by executing Play().
