Hi Michel!
Well I waited for a response from You as long as I could… I am now going to be “Deep in the Weeds” the next several days so I will not be able to have a detailed or extended back & forth with You.
So I have created a Demo which I believe shows the principles of what You are looking to accomplish: Timeline-JHSv4.hype.zip (41.8 KB)
Live Demo here.
The key element here is we are NOT going to use the “Main Timeline” for these scene transitions, we will use an alternate (new) timeline in “Scene 1” called “Slider”. This alternate timeline is critical to having things work as we want them to work.
Drag the “Scrubber” on the left side up or down to view the different book rows. The scrubber controls the “Slider” timeline (via “On Drag” in the “Action Inspector”). This “Slider” timeline is the key to going to the correct row when we return to “Scene 1” from the book content scenes (i.e. for Books 1, 4, & 7).
Books 1, 4, & 7 are set up for mouse clicks. A click triggers a “Push Bottom to Top” scene transition and goes to the corresponding scene (“Book Content~Pages”) for that book.
There is a “Back Arrow” on these “Book Content” scenes that takes the viewer back to “Scene 1”. This “Mouse Click” trigger runs a scene transition (“Push Top to Bottom”) AND runs a Custom Behavior matched to the corresponding book row (via Scene 1’s “Slider” timeline)… e.g. going back to “Scene 1” from the “Book 7” content scene we trigger the Custom Behavior “timeBook7”.
“Scene 1” are where all the “Custom Behaviors” are located that will set the “Slider” timeline to the correct mark - and hence set the corresponding book row correctly.
