Timeline Pause works as expected in Editor, works wrong in Runtime

    Hello there, I have a simple timeline with two clips, one after each other.

    First clip - opens doors (two panels are move aside)
    Second clip - closes doors (two panels moving back together)

    When I preview timeline and hit Pause/Resume animation clip stop and resume as expected.

    Here's animated GIF of what's happening:

    At first I test it hitting Play on the timeline window in the Editor and it works as expected.
    But then in runtime, when I pause timeline from the code (there's marker around middle of the track which does that) first animation clip is reseted back to frame zero, producing this effect of once opened doors suddenly shut closed.

    This is animator for the animations:

    Code:

    What's happening here - any ideas?

    Thanks,
    S.

    @julien-b @seant_unity Guys, could you please check it out:

    Two clips put sequentially on the animation track. While in editor, it works fine:

    Begining of animation - doors closed:

    Animation progresses

    First clip finishes, timeline is paused, doors stay opened (according to animation):

    BUT during runtime, when I pause timeline (from the script) here, first clip goes back to first frame and doors are closed:

    I tried to offset signal - no difference.
    All clips have looping off

    Would appreciate a hint what's happening here - I really want to use timeline here, don't want to fallback to legacy animations and events.

    use activation tracks rather than animation tracks?
    activation tracks just activate and deactivate an object (which could contain an animator set to play on awake)

    .Pause() will release the timeline from the animator, so what you are seeing is control being reverted back to the animator controller. In editor, the controller doesn't run so it the animation isn't being updated.

    Instead of Pause()/Resume() you can play with the speed of the graph as a workaround.

    this.director.playableGraph.GetRootPlayable(0).SetSpeed(0) == Pause()
    this.director.playableGraph.GetRootPlayable(0).SetSpeed(1) == Resume()

    This will work similar to a 'Hold' on the playableDirector.

    Thanks for the hint. Is this a desired behaviour and I am doing something wrong, or it's going to changed in the future?

    I'll call it a known issue. It's something we'd like to fix, but it hasn't bubbled up to the top of the pile yet.

    OK, it works with a workaround, so gotta live with it for the time being :cool:
