Hi @mvaneijgen,
Your prompt advice made me very happy, and I really appreciate it!
I found a problem when using the ScrollTrigger and Observer plugins together, so I attempted to use the Observer plugin to manipulate a single timeline.
I have uploaded a new demo to CodePen:
https://codepen.io/gritzweb/pen/bGzgQgp
I've added "addLabel("endAnime1")" to "addLabel("endAnime4")" in the timeline. My intention is to "timeline.pause()" at this point and scroll forward to the next section.
However, it seems that "timeline.seek('endOpening1')" and "timeline.play()" are not behaving as expected.
Could you please advise me on how to control the timeline? Your assistance would be greatly appreciated.
